Hi, hoping someone can help.

I have a laptop with a Intel N6230 wireless card which I'm having a strange issue with. I can be connected fine to my wireless network but if I perform a reboot the laptop 'connects' to the network however has no internet access (nor can I access the router via its ip address).

The only way i can get it working again is delete the wireless adapter via the device manager, let windows re discover and install it, and all is fine again - nothing else is required. It continues to work fine until I shut down and reboot where it drops again (sleep modes or hibernation do not cause any problem).

I have a second XP laptop which has no issues at all.

Any ideas? I have spent a fair amount of time googling but have come up blank.

Many thanks in advance...

I've been on the phone with Norton, Microsoft and my ISP (Cogeco) about this issue and have ruled out that Norton Internet Security Suite 2010 and Cogeco are not the issue. Microsoft have been calling me in these recent days to figure this issue out and to help me solve it.

My issue is when I'm browsing the site (my profile, etc.), my network icon in the system tray shortly after says something like 'No Network Access.' Soft rebooting the machine puts things back to normal (having network/Internet connectivity). When this issue happens, it doesn't even recognize my routers or anything beyond the scope of my computer.

I have all the updates for the OS. I'm an expert/advanced user so I know what sites to stay away from (ones with worms, trojans, etc.). I've run Malwarebytes in Safe Mode (no networking); also, Spybot S&D and Super Antispyware. Only cookies have shown up with no other threats. I'm able to access the site no problem with my laptop with Vista on it, so I know it's not a router issue.

Any thoughts?

Hi there, I have recently been having difficulties with connecting with my wireless connection. We have a in-home router that is connected to two computer's downstairs by cable. I however own a Acer, Windows 7 laptop that I mainly use upstairs and I get a Excellent signal strength.
I have connected to my Home wireless connection before with no problem but recently the connection keeps coming up as ~Identifying... No Internet Access.
Also when I have had connection to this network prior to this problem the connection is under Home. But when I try to connect to the same network it comes up as Public or just keeps Identifying. I have the connection set to Connect Automatically.
Also the yellow triangle with the exclamation point almost always pops up immediately when I reboot my system or after I Disconnect and Connect the network again. I have tried Disabling and Enabling the network in the adapter settings and this does not work either. In the manage wireless networks tab, I have repeatedly deleted the connection and reentered the security password and again put it as automatically connect but it still comes up as Identifying. I have seen many people with this same problem and have tried many of the suggestions to no avail.
It is rather bizarre because my connection will be in this Identifying state for a while and randomly connect properly and I have no idea what makes it go off and on so erratically. I just had it working again for a few days and it is again acting up. I would appreciate the help and hope I can get this resolved and not have to wait tell my connection randomly works again xD

I'll preface this by saying that with only one other exception the internet on my Windows 7 system has been rock-steady, and I always install Windows Updates as soon as they're available.

Last night was a large series of updates, and after they installed and the system restarted, the little internet indicator has a yellow triangle on it and the tooltip reads "Unidentified Network No internet access".

This has happened exactly once before, a few months ago, again following a Windows Update, the system lost internet connectivity. I honestly have no idea how I got it working again that time, and all I remember for sure was that I rebooted the system twice.

This time, however, after dinking around with both the Local Area Connection settings, and the Device Manager(and finding absolutely nothing wrong, just like last time), and rebooting a total of SIX times in the process, the system still cannot access the internet in any capacity.

This is infuriating because I depend on the internet for my work and for online tasks I cannot perform on the secondary computer I'm using to make this post.

Skipping right over the ridiculousness of Windows Updates breaking the system's internet access on multiple occasions, I simply need to get it working again, ASAP.

I have an Acer Aspire M5800-U5801A desktop purchased in late 2009. Onboard Intel® 82567 Gigabit Ethernet Controller. Originally came with Vista and upgraded to Win7 through Acer's free upgrade program. All features of the system were operating without noticeable issues until recently.

I put the computer to sleep/hiberate every night. Woke up one morning a few days ago and noticed there was a bland screen I'd never seen before which simply read that there was a "fatal error" and that the system could not come out of hibernate and instead was rebooting. Don't know if this is relevant but figured it could be more than a coincidence. Note that pretty much right after this (maybe with 24 hours) was when the internet stopped working. Also I noticed that since this error, the system takes noticeably longer to boot up. I believe a screen appears briefly saying something about Eagle BIOS with a message saying something like NOT AUTHORIZED TO DISMANTLE/ASSEMBLE that had never appeared before. After this the normal Acer screen appears that I had been used to seeing on bootup. Again, this may be unrelated but I'm trying to give every possible bit of info I can think of to fix this problem.

So when Win7 loads, it searches for a network and instead of my normal homegroup, finds an "unknown public network" with no internet access. Diagnosing says that the system cannot connect to the gateway device and says to reboot cable modem. This leads to no success. Checking the driver shows it's up to date, the device is working properly, etc. Running IPConfig shows that it's connected to Comcast, there's a default gateway(4 sets of numbers), shows "MEDIA DISCONNECTED" on two lines, there is an ipv4 address. I thought my modem might have broken since it was from 2003 so I went to Comcast and got a brand new Motoralla and new wires/cables and the problem remains exactly the same, so I'm totally out of ideas now.

One other issue that may have relevance. when I went into BIOS, the Onboard LAN Option ROM was disabled and grayed out with no ability to enable it.

Does anyone have any ideas what went wrong? Seems so strange that the internet would be working 100% fine and now cannot connect. Is it possible the onboard card itself died? I'd think if Win7 could detect it and says it's working properly then no, but I'm not an expert.

Sometime ago I had to install ORACLE VIRTUALBOX to do some linux/debain work with UBUNTU. NOW I'm trying to restore my machine. When I uninstall the VIRTUALBOX the network quits working. All the network drivers show up in the device manager. I haven't seen any settings between the 'before' and 'after' driver settings. Yet when I connect to my wireless connector I get 'Limited Access', No internet when connected to my wireless cable modem. Further, running IPCONFIG /ALL only lists the bluetooth driver as present. The wireless and wired adapters are not listed. Yea, Sounds like a driver problem.

Restore to the restore point prior to the deletion and the wireless internet connection is back.

I downloaded the most recent drivers (network adapters, usb, etc). Installed them. Network still works. Remove VIRTURALBOX and the network is no longer present. Reinstall the newly downloaded drivers; reboot; Still the same result. IPCONFIG doesn't see the adapters and can't connect to the Wireless modem.

Restore the restore point and the internet is back, or I couldn't write this. I can live with the VIRTUALBOX installed (not my preference), but I don't know what other parts may be broken because of it. I would like to remove it without having to spend days doing a wipe, new install, configuration, updates, and re-install of all programs.

I decided to just post this as a new thread, as it appears to be getting positive results for most people. I highly recommend it anyway, as you will eventually encounter this if you apply all of your updates...

For those of you reporting problems with your network after updating MS Office or installing Adobe CS3 -

If you are having Internet connection problems related to "Unidentified Network" showing and the "!" over your NIC icon, then this should take care of it:

Check to see if you have this little devil in your services list:

"##Id_String2.6844F930_1628_4223_B5CC_5BB94B87 9762 ##"

If you do, stop it and disable it. It is actually the Bonjour DNS Responder Service, and I believe it is the cause of the "Unidentified Network."

The Unidentified Network disappeared after stopping this service and a quick disable/enable of the NIC, restoring Internet access.

I Actually just rebooted, edited this post, and then re-enabled the offensive service to see what would happen...Immediately after enabling the NIC and this bastard service, the "Unidentified Network" returned...stopped it, disabled it, disable/enable NIC...Internet back up and running and no "Unidentified Network." (woot - woot!)

Hope that helps! I haven't had issues since...

FYI - I experienced this in both build 7100 and 7127...I am running 7127 now x64 - and discovered this fix just last far so good just rebooted and then edited this post...I believe this fix will solve 7100 build issues too; however... I have not tested 7100 again yet.

...I also re-enabled Win 7's Discovery Mapping services, but always leave IPv6 disabled just because I am not using it.

...another two reboots, and a hard disk addition, and no problems with the Internet! - If you tried another fix such as changing the address of your network adapter, under "Advanced" - this is not necessary...I set mine back to "Not Configured." Everything is working fine as long as the Bonjour service is not running...

My system:
Quad Core Q6600

For the record, there is some blame pointing towards the following software, of which I do have installed and running properly:
Office 2007 SP2

Hello all:

I've found several others having the same problem as I on this and other forums but no answer yet.

I have a home network that includes an XP-based home server of sorts. I hang my Drobo off that server and share it to my home Network. On all my other PC's I access it as my "N" drive (N for network). This has worked fine through XP, Vista and even Windows 7 installations on the same PC (discussed below) for some time. But now whenever I boot up my system with Windows 7 I get the

"Could not reconnect all network drives"

error every time I boot.

When I click on the "N:" drive through Windows Explorer or a link on the desktop W7B asks me for a userid and password. I can literally type anything in the Userid field (complete gibberish works) and add a password or not. When I do, my shared drobo connects as N: (I refer this as a manual connection for the rest of this post). Thereafter all my apps can use, see, change files on N: . All is golden until my next reboot.

It's important for me that the system automatically connect because a dozen or so of my apps routinely interact with my "N:" drive. For example I use the program Second Copy to automatically backup several directories and drives across my network to my Drobo on N:. That app won't work until N: is connected. My iTunes library is situated on my Drobo. iTunes won't see my iTunes library and gives error messages until I manually connect the N: drive and on and on and on from app to app. My N: drive is my data repository for all my devices.

Here's the rub. When I first installed W7B (on the exact same PC) I installed it as an upgrade to my then current Vista x64 installation. After that upgrade, I had no problem. That N: drive auto connected on bootup just as it had when I was running Vista on the same PC and just as it had when I ran XP before on the same PC.

Subsequently I chose to do a fresh W7B install on the exact same PC that I had previously installed the WB7 as a Vista x64 upgrade. That's when this problem arose.

Despite dozens of hours of research and tinkering I have NOT been able to get my shared N: Drobo drive hosted off an XP computer to automatically connect when I boot up. I have changed NOTHING on the XP server. I have changed nothing on Drobo (though I did try "Unsharing" and "Resharing" the drobo on the XP server to reset / update directory permissions - this did nothing). My other networked Vista/XP PCs continue to access it as their N: drive without incident. It is only my clean-install W7B PC (and a tablet PC I did a fresh W7B install on) that cannot automatically connect to that shared network drive on boot.

What is truly strange is that on this EXACT same PC the share worked flawlessly (as always) after an upgrade from Vista x64, but when I did a fresh/clean install on the EXACT same PC, the problem raised its head.

- All PC's on my network are on the same workgroup.
- The problem persists whether or not I have a homegroup activated
- I have no problems accessing shared drives BETWEEN PCs running WB7
- I have no problem accessing the shared Drobo on the XP PC from other XP/Vista PCs
- all pcs are behind a NAT router so firewalls are turned off
- no anti virus software is running on any PC (not that anti-virus software ever caused an issue here before)
- I have tried changing most of the Advanced Sharing Settings in:

Start --> network and sharing center --> change advanced sharing settings

including turning on and off 'password protected sharing'

- When I mapped my network drive to N: I did it using the proper 'serverdrobo' naming convention
- I note that when I click on the "Browse..." button my networked XP server does not show up as an available network device (though I can still connect to it by manually typing serverdrobo
- I, of course, always check the 'Reconnect at logon' checkbox on the "Map Network Drive" dialogue box
- Whether or not I check the "Connect using different credentials' checkbox on the "Map Network Drive" dialogue box makes no difference.
- Under the 'Computer' item on the left side of Windows Explorer, the N: drive shows up (before manual connection) with a red x through it.
- I note that under the 'Network' item on the left side of Windows Explorer, only W7B PCs show up even though W7B shows all network PC's even XP PCs in the Network Map
- Clicking on the 'Remember my credentials' checkbox on the "Enter Network Password" screen when I manually connect makes no difference - WB7 clearly doesn't remember them.
- NOTE: I do NOT login with the same userid and password on the server and on my WB7 machine. I never had to before (including when WB7 on this PC was an upgrade from Vista) so I can't imagine that that is the problem. Note, all other PCs on my network access the shared Drobo from ANY userid on any other PC

Control Panel --> Network and Internet --> Network Map,

(after manually connecting N: by clicking on it, that is)

I am at a loss for how to proceed. Any suggestions?


------------------------------------------------------------------------ UPDATE ------------------------------------------------------------------


Folks, after spending the better part of a second day I solved it. Though I don't know how. About an hour after giving up today, after a reboot, I noticed N: was connecting. I really don't know how/why.

The last thing I did (as mentioned in parenthesis above)(though I did try "Unsharing" and "Resharing" the drobo on the XP server to reset / update directory permissions - this did nothing)was to copy files from N: (after a manual connection) to my C: drive. When I connected that last time it asked me, as it does/did sometimes, though not always, for a userid and password. I entered the server's userid (different from my W7B's userid) and password and checked the 'remember my credentials' field, all as I had many times before).

Funnily enough the system crashed when I was trying to do that transfer of files which lead me to reboot (pressing the power button to shut down and restart). The next time it started I didn't even notice that the N: had connected at first (I was on to a new project and wasn't paying attention to the boot process). About 15 minutes in I noticed there was no red x beside the mapped N: drive in Windows Explorer as there always had been in the past. Since I was pretty sure I hadn't done a manual connection I decided to reboot and test ... Lo and behold, N: automagically connected at boot and I don't know why.

I created a save point so I can get back here if something goes awry. For now I'm just happy it works. I don't know how to replicate it.

I NOTE THAT THE PROBLEM STILL SUBSISTS ON MY TABLET RUNNING W7B, so I am now confident the problem has nothing to do with how my XP server is configured. It has something to do with the way W7B is configured. If I solve this problem on my tablet I'll write another post. Hopefully by then I'll have isolated what worked.


I have two pretty annoying problems with 7 and they are as regular as clockwork and I can not isolate the cause of these problems. The first one is with the network card. Every single time I reboot, on reboot, I loose internet access...not necessarily my network access but definitely internet access and I have to go to the device manager and uninstall the network card and then reinstall. This takes care of the problem 99% of the time.

Next is the audio/sound issue. If for any reason the machine is put to sleep or hibernation or I loose all audio after the machine re-awakes. However, I do get whatever annoying microsoft sound that signifies it is going to sleep or I am having to restart the machine to get the sound to work again. I have to restart the machine to get my sound back only to hear some sound as the machine is going into reboot....drives me insane! All drivers are up to date and I have tried older drivers to no avail. Any help would be greatly appreciated. Below are the machine specs.

Hi Guys

Installed Windows 7 on my Acer laptop with no problems, all was working fine was using the inet downloading updates etc all ok ,was so sweet after Vista.
Last night I rebooted and I no longer have access to the internet.

I checked the internet connection by plugging in my XP laptop all ok
So its somthing with the Acer laptop and windows 7

Hardware in the device manager is all ok,
Updated network card drivers , still nothing.(nvidia card)

Tried to use Windows 7 to diaganois the issue , Windows cannot find a problem.

I cannot find anything with hardware or software which leaps out and says, here be problem.

The GF wants me to go back to XP , I am resisting, I like this Windows 7 ,but not for much longer
Please help


Got the internet back by disabling my network card then re- enabling it
However I have to do this everytime I reboot
Driver issue?

Upgraded my Vista Ultimate desktop PC to Windows 7 RC and everything works perfectly... apart from the fact that I can't get an internet connection.

I have a wired ethernet connectio to my adsl router and the router is connected to the internet, as my laptop does still have access.

The wierd thing is Windows 7 is talking to the router just fine. DCHP is working and it get's an IP address no problem and I can log in to the router. But the router internet connection is broken.

Anyone any ideas what could be wrong and how to fix it? I have tried disabling and re-enabling the network adapter and that does not work. I have also rebooted the router and that doesn't help either. I have searched for new network adapter drivers (Marvell Yukon) but the ones I have seem to be the latest.

Any suggestions?


Well, I have managed to get it working by setting up a static ip address and dns servers and then going back to automatic settings, and it connected to the internet. Whether it will keep working after a reboot, who knows.

Greetings.... as a first timer in this forum, I trust I'm in the right place.... This issue is a little complicated so I will try to be quick about it. We utilize a virtual network adapter along with a Sprint broadband adapter which communicates on an EVDO-A platform for a mobile computing system (public safety). By itself, Win7 functions fine when accessing the broadband network. However, problems arise when we introduce the virtual network adapter which provides access to a secure network. Initially the VNA works fine until the modem for the broadband drops out (dead zone, power outage) then "internet access" is denied to the VNA upon restoral of services. This "no internet access" indication is persistent until we power down the modem, and reboot the workstation.... this loss of network access for a first responder utilizing this mobile computer system can be quite troublesome to say the least. After many hours of troubleshooting, we are convinced that the problem lies with Win7 and not any other of the components.... as we certainly do not have this problem in an XP environment... as a side note... this issue of having a network connection but "No Internet Access" on behalf of Win7 is a little "crazy."

Hi all,

We're pretty much stumped as to why we're having this problem.

We've been with our ISP for nearly 2 years without this problem, and about last week suddenly 2 of the 5 desktop PCs on the network suddenly developed the local internet access issue. 3 of the 5 desktop PCs use ethernet/wired, 2 of the 5 desktop PCs use wireless N. The problem seems to happen equally to wired or wireless PCs.

The problem is intermittent, it has since happened on 4 of the 5 desktop PCs on the network.

The problem "symptoms" go roughly like this:
-The affected PC will stop loading web pages (in any browser) message: cannot load web page. The network adapter will STILL think it has internet access.

-The affected PC will stop loading web pages (in any browser) and the network adapter will show local only.

The PCs have shown a range of problems and I believe we've tried most of the fixes out there.

- Enabling/Disabling the adapter will sometimes work. Most of the time it will not work and there will be no internet access.

- Pinging or an address will sometimes work but mostly cannot reach it.
- ipconfig /renew /release /renew6 /release6 etc will sometimes work after multiple attempts and a reboot, but often gives the error "cannot find file.."

- flushdns will complete but doesn't bring back internet access.

- rebooting the modem router will sometimes work, sometimes not. Sometimes it will bring but access on ONE PC but NOT on the other.

- rebooting the PC - same as the router.

- checked for the bonjour / id string service, only one of the PCs has this service and it is disabled anyway.

- Tried the Vista reg fix for forcing DHCP broadcast. Worked on one of the wireless PCs, but the next day after turning on the PC the intermittent/local only was back.

- We have tried 4 different modem routers. ISP provided (thomson BEbox), Belkin modem router F5D8633-4 (we used this one for 2 years+ and never had a problem), and 2 new Belkin F5D8635-4 v1

- We rang our ISP who told us there were no problems detected, they also said they did a 24hr line test and it was fine.

-We've tried setting Google public DNS on all the PC network adapters and the router and the intermittent internet still occurred.

- Tried disabling ipv6 and problem still occurred.

- Checked windows update for recent updates but the only thing prior to the problem was an Microsoft Security Essentials Client update - tried disabling Windows Firewall and MSE and still no access

- Tried updating the wireless driver on one of the PCs that lost access, made no difference.

Our setup looks like this:
Modem Wireless Router --> 2 wired desktop PCs, 1 TP-Link wireless access point --> 1 wired desktop PC, 2 wireless PCs.

All computers are Windows 7 ultimate 64bit

All the computers are custom builds.

I have a Samsung Windows 7 starter netbook which I occasionally turn on and connect wirelessly - have not yet experienced intermittent internet with this.

We are really pulling our hair out here! Not sure why we have been able to use the net for years and suddenly almost all computers on the network have this issue! Sometimes at the same time, sometimes independently. Internet can suddenly drop on one or two PCs just by loading google (router internet lights still on)

Since all the PCs are custom built I'll have to go dig out the motherboard model nos and so on but my PC is:
AMD PhenomII x6 core
6GB ddr3
primary hdd: 500gb sata, x1 seconday hdd: 250gb
mobo: Gigabyte GA-880GMA-UD2H
Ethernet: Realtek

Sorry for the super long post, just trying to put all the info I can think of that might be needed. Many thanks in advance if you can suggest why this is happening and what exactly could be causing it since we've tried changing multiple routers and the problem is happening on more than one PC...

I've tried to list all the "fixes" I've attempted and think that's all of them, but I might have missed one or two and will probably be trying any more that I come across.

This morning my computer restarted itself after carrying out a Windows Update, unprompted, as usual. However, when I woke up and logged in my wireless network would not allow me internet access.

Instead I get a yellow exclamation mark over the signal strength bars. In addition to this the windows wireless tool just displays "Identifying... (Tiscali)" constantly. It is sending packets but not receiving any what so ever.

In addition to this, and I'm not sure it's relevant or not but I am using Avast! anti virus and it's "Web shield" function will not turn on.

I have tried a wired connection with the same result. I have also tried another router wirelessly with the same problem.

Usually this can be fixed by a reboot of the computer and/or the router however no such luck.

I have tried a few things i.e. updating drivers enabling/ disabling the adaptor. Any help would be greatly appreciated.

I have two Windows 7 Ultimate computers and around
10 Windows XP (Home and Professional, SP2 and SP3) computers trying to connect
to it. It's just a LAN (no internet access).

I have set all of the
password-protected sharing off on the Win 7 systems. I have tried opening up ALL
of the permissions and such (since security is not really an issue).

problem I'm having is this:

When I try to map the network drive, it won't
let me merely connect to it. So, I have to click map network drive on the XP
computer and hit "login with other credentials" and enter the username/pass for
the user account on the Win 7 machine (we'll say Bob for user and Smith for
password for the sake of example). It will mount the share (which is actually
the C: root of the drive) just fine.

The only problem is the moment you
restart the Windows XP system, it will lose the connection. My fix for it was to
create a .bat file that contained the following:

Code: net use S: /delete net use S: Server1Win7server1win7 Smith /USER:Bob /PERSISTENT:YES net use T: /delete net use T: Server2Win7server2win7 Smith /USER:Bob /PERSISTENT:YES
I put it in the Progam FilesStartup folder to run upon boot. For the most part,
it seems to work after a fashion. Some of the computers, though, will drop the
connection to the two Windows 7 systems and need to be rebooted 1-2 times before
they get it back again. Even clicking the .bat file manually will have the same
result (you will have to reboot) if it drops the connection while you're using
it. Plus, sometimes it doesn't map the drive correctly (I assume because the
batch file is running before the connection has a chance to initialize on the

Any help would be much appreciated, as I am completely at a loss
here. Any solution that would allow me to map the network share for both of them
and it remain persistent would be wonderful.

PS - I've also tried adding
an "Everybody" user to the permissions on the Win 7 systems with full access,
but it only seemed to cause problems with the existing connections.

It might also be prudent to mention that both the Windows 7 and Windows XP
systems are all 32 bit. I've also disabled the firewalls on the two Windows 7
systems. Neither of them have any antivirus or security software installed.

Under Windows7 RC 7100 with a modem (Nokia N91, with pcsuite driver last version), the internet connection worked well at the beginning, and after a few days, without changing anything, it now always says "no network access", with the yellow triangle.
I'm in the African bush without any local help but crocodiles for suicide in case I can't solve the issue with you…
All troubleshootings have not detected any issue.
The modem is still connecting to the computer (Dell studio 17), IPs are appearing, but "no network access".
On another computer under xp, the internet access is working fine.
I have already:
- unticked the IPv6
- switched off the other network cards (ethernet and wireless) in order to avoid conflicts
- switched off the windows firewall
- rebooted
- tried public and office networks (home network impossible without IPv6)

Please help!
Thks in advance.

After experiencing some problems with stable connectivity, I went into device manager and selected to uninstall the driver for my Qualcomm Atheros AR5007 802.11b/g WiFi Adapter. After rebooting, I selected the option to automatically update the driver. After all this, I keep getting "Not connected- No connections are available".

1. It's not the router. (The internet is working)
2. Already tried to do system restore. (System restore can't access a certain file and won't let me).
3. Already tried Roll Back Driver.
4. Another weird thing is that when looking at the status of the network connection, it states that the speed is 412.3 Gbps. Despite this speed being ridiculous and it not being connected to anything.
5. Trust me, it's not the router.

ffs, somebody? anybody?

Hello all,

I'm new around here and I've got a problem with my networking.

Relevant Hardware:
Asus Sabertooth (first verson) 990FX Maim board.
2x WD 7200RPM HDs
Windows 7 Ult x64

I install 2 disk hard drives into my computer to set them up into a Raid 0.

Now I got them installed and the the raid set up. But when I boot back into windows I find that the Realtek Network Controller is missing. After several days I finally learned that its actually a bug between Windows 7 and the Realtek Network Controller and a lot of people seem to be suffering from it. About the only method is to cut power to the PC for 10+ minutes.

The gist was that Windows 7 put the network controller into a "Deep Sleep Mode" and the BIOS could not override this (in fact the BIOS said the controller was enabled when it really wasn't). Since it seems that the actually active BIOS and the one I actually flash are not exactly the same thing I'm thinking this issue is caused by Windows 7.

Now I went ahead and installed Windows 7 on the Raid 0 setup to see if it was just OS specific. Turns out the device was still turned off and neither OS install could turn it back on.

I did go to the Realtek website (the Asus drivers were out of date, although I tried them at least once anyways) and installed those drivers.

When I reboot the computer, it says the device is there, if I try to reinstall the device it says that it doesn't exist again. The behavior is exactly the same no matter which boot I use.

Now the entire rest of the system works perfectly and the actual port was at the far end of the board from where I was working.

So right now I've tried both of my ethernet cables. Both work fine when I plug them into my laptop but not my desktop so I don't think those are the issue. I have taken some q-tips (no cleaner) and wiped off the contacts on the motherboard and the cable although this produced no change in behavior.

What is very weird is that both the router and the mainboard have a small LED light that is supposed to light up when the cable is connected. When I hook up the cable, the router's LED is on and doing that rapid flash it seems to do when talking to a computer (and it does this continously) but the mainboard's port does not light up.

On the Windows end, when the Device Manager says the Network Controller is working perfectly, the message is that its "Connected to a Unknown Network" and "No Network Access" (not internet, just network, seems to be different errors). If I unplug the cable from either end then it just says "Not Connected - No connections are available".

Another thing I noticed (memory is a little blury after 5 days) is that when the Device Manager says that it cannot find the Network Controller the registry data for that controller (in the current control set) is also missing.

And I apologize, this should have been written earlier, but unchecking the box's in the Controller's power options (so the OS couldn't turn it off) had no effect on the device disappearing.

This last round I had windows auto-install a driver for the controller is and is coming back with the reboot for the time being.

Windows cannot seem to connect to my router. Info above.

Thats about all I can give you. I don't have any space on the mainboard to put a NIC card because all of the space is taken by 2 bricks (Radeon 6950 cards) so the port is all I've got.

Can anyone help me? Thanks!

This post is very long. Please read only if you are patient enough to help a
newbie. These questions mostly pertain to XP networking, and this seems the
best forum for networking. Referrals and suggestions are very welcome. Even
if you can answer just one or two of my many questions here, that will help
a lot. Just quote the text you are replying to so I know which question you
are answering. I get confused rather easily.

Before beginning the networking questions, in Belarc Advisor under
"Installed Microsoft Hotfixes," SP2 (KB811113) does not have a green
checkmark next to it (lacks the data to allow verification). Is that normal?
All updates after SP2 show up as SP3, and all of them do have green
checkmarks and are verified. Here is a synopsis.

Unmarked hotfixes lack the data to allow verification.

In another area of Belarc, Local System accounts show "HelpAssistant" and
"SUPPORT_388945a0" as disabled accounts. Is that because I disabled Remote
Assistance and Remote Desktop in Control Panel - System - Remote? Could it
also be because I disabled Messenger from starting up with Windows?

Is this a good place to get help with what I need, or is there an online
forum for newbies you might recommend, because this could take a while. I
basically need instructions that an idiot could understand.

I will also need help determining which of the numerous Services that start
up in WinXP I need and which I do not. The MSCONFIG in XP sucks. I can't
maximize it, and there is hardly any information in either MSCONFIG or the
Task Manager under Services. Program names and paths are not mentioned, just
names of processes. How do they expect me to find anything? I need a good
third-party Startup Manager/Task Manager in one program that is not very
expensive. WinTasks Pro is too expensive. One option is the Ultimate
Troubleshooter, which is $25. I haven't it tried yet, but I am open to other
options. Their site has a list of Processes (Services). SysInfo has a list
of Startups. Spybot helps me to some extent with Startups but not Processes
or Services.



Some of those XP background processes might be what is causing my LAN to cut
out from time to time. When that happens I lose both Internet access and
network access. One of the network icons disappears from my taskbar. Other
times it doesn't, and when I click on it to "repair" it it freezes. When I
try to bring up "Network Connections" it freezes. A reboot brings everything
back to normal. Firewall, antivirus and antispyware are all up-to-date, full
system malware scans are run regularly, including online scans. I really
don't think malware is the problem. I think it's background processes in XP,
but I just don't know enough about them to mess with any of them. XP has
only been installed for a few days on both PCs. Both of us are new to it.

Please assistant with Network Setup and with Binding/Unbinding TCP/IP from
File and Printer Sharing for better security. I am the "network
administrator" of this home network but new to XP and not a techie or
certified expert. Many web sites and Microsoft articles about networking are
geared toward more advanced users, and I do not understand all that is in
them. Need step-by-step advice. Forgive me if too much information is below.
Better to have too much than not enough.

At present, only two XP Pro SP2 computers are connected, this one and one
other desktop. I do not know how to connect the Win95a and Win98se laptops
or if it is even possible since they use 16-bit PCMCIA to connect to the
ethernet hub. The XP network setup wizard does not support Win95. The old
laptops connected fine to the network when this computer and the other
desktop both used Windows Me.

With XP, it is all user-level rather than share-level access, and I don't
know how to configure Win9x for user-level access. Let's do that later after
we get things configured properly for the two XP machines. Also, I need to
password protect the shared folders, the access to each computer, and each
network printer. Can't see how to do that with XP. With 9x, it was easy to
password-protect a shared printer or a shared drive.

SBC Yahoo! DSL Technical Support and 2Wire Technical Support state that the
2Wire Home Portal 1000HW is both a DSL Modem and a Router. I do not know if
it is a gateway, but I suspect it is for three reasons: (1) Windows uses the
word "gateway" in the name for the connection, (2) Windows preselects the
"residential gateway" option in the network setup wizard, and (3) the 2wire
people say that I cannot connect a separate "residential gateway" to the

All protocols were automatically installed and configured by Windows except
for IPX/SPX, which I added after reading that that protocol (or NetBEUI) is
the key to separating File and Printer Sharing from TCP/IP. I just don't
know how to do it. On the options for each network connection in XP, I see
nothing about bindings. In Win9x, the bindings options are easier to find.

1394 Net Adapter
2Wire Gateway USB
MAC Bridge Miniport (Network Bridge)
Realtek RTL8139/810x Family Fast Ethernet NIC (Disabled)
HSP56 Micromodem (COM3) (56k Dial-up Fax Modem)

- Realtek is disabled, nothing is plugged into my ethernet port. A Z65n
network printer will go there later to replace my existing Z42 parallel port
printer. We don't have a cartridge for the Z65n. That's the only reason
we're not using it.

- The Network Bridge connects 1394 and Realtek, so that the new Z65n
printer, once installed, will be available to the existing network.

- The 1394 Net Adapter is used with my network and/or the Internet, but I am
not exactly how or what it does. Windows automatically configured it. The
1394 sounds like firewire, but I don't have any firewire devices installed.
Firewire is enabled on the mainboard, but I'm not using it. Or am I using it
through this adapter? Is this just an internal connection needed for Windows
to set up the Internet and the network? Windows needs at least two adapters
for that, according to the XP Help and Support.

** Which adapter is the one that connects to the Internet, 1394 or 2Wire? **

** Which adapter should be used for File & Printer Sharing? **

- The Realtek Ethernet NIC is disabled at my choice because nothing is
plugged into that port. Since I'm already connected to the network via USB
(or 1394), I cannot also be connected to the hub or there would be

- I plan to connect an ethernet cable to my open ethernet port at some
point. The cable will go from my ethernet port directly to the ethernet port
of a Lexmark Z65n printer (when we get a print cartridge for it) without
going through the ethernet hub.

- When I re-enable that Realtek ethernet port for the Z65n printer, that
printer will automatically become part of the existing network through the
Network Bridge, theoretically.

- The dial-up connection is only used when the LAN is not available.

- When dialing in with the dial-up connection, TCP/IP completes the
connection successfully, but a connection to the remote computer cannot be
established with IPX/SPX (error 733). A dialog box asks me if I want to
"Accept" the connection as is and if I want to check the box "Do not
request the failed protocols next time". I click "Accept", but I'm afraid to
check the other box about failed protocols because I don't know how
difficult it will be to reverse that decision if things change.

- I wonder why the 2Wire Gateway USB connection is only 10Mbps (rather than
400Mbps) for USB 2.0, unless it's because the router connects to an ethernet
hub which can only support 10Mbps.

Option #1: "This computer connects directly to the Internet. The other
computers on the network connect through this computer."
(This is the option I thought was correct, but Windows did not preselect

Option #2: "This computer connects to the Internet through a residential
gateway or through another computer on the network"
(This option came up by default in the network setup wizard when Windows
searched for a shared connection. Maybe this one is correct. This is the
option I am presently using on this computer.)

Option #3: "Other"
(This option is not used, but it was set up this way originally. At that
time, there was no USB cable between the router and my computer. My computer
was connected directly to the ethernet hub. Then we heard that the USB
direct connection method would be more secure, so we switched the wiring to
the current configuration as recommended by the 2Wire people and my ISP.)

1. Which option for the network setup wizard (see 1, 2 or 3 above) is
correct for this computer?
2. Would option 2 be correct for all the other computers on the network?
That was used for the other XP machine.
3. Since the modem/router connects to my machine with USB, there is no power
to that USB connection when my computer is turned off, right?
4. So the other computers can't connect when my machine is turned off,
5. Does my machine need to be turned on all the time in order for the others
to connect to the Internet?
6. Is my current network peer-to-peer or client/server?
7. Which adapter is the one that connects to the Internet, 1394 or 2Wire?
8. Which adapter should be used for File & Printer Sharing, 1394 or 2Wire?
9. Network Bindings need to be reconfigured to isolate File & Printer
Sharing from the Internet without losing my ability to connect either to the
Internet or to the other computers (and the other computers to me). I need
step-by-step instructions, not too technical.
10. Password protection needs to be added to each network printer and each
shared drive/folder. I need step-by-step instructions, not too technical.
11. The network access and Internet connection through are sometimes lost
for no apparent reason. Any idea why? Sometimes the 2Wire Gateway USB icon
disappears from the taskbar when this happens. When it doesn't disappear, I
can't right-click on it because it freezes. Sometimes Start -- Network
Connections will not open. I suspect it may be some background process
running in XP. The only way to get the connection back is to reboot the PC.
12. Remote Desktop and Remote assistance are both disabled. Do they need to
be enabled?

After the two XP machines are configured, I will need assistance setting up
the two Win9x laptops. Looking forward to hearing from the experts.
