I Recently upgraded my system and performed a fresh install of Windows 7 ultimate. Everything went smoothly, until i tried connecting to the internet, where i received an yellow triangle and 'no internet connectivity.'

Important Computer specs are: Intel Core i3-2100 3.10GHz (Sandybridge) Socket LGA1155 Processor
Seagate Barracuda 7200.12 500GB SATA 6Gb/s 16MB Cache

MSI H61M-P23 Intel H61 (Socket 1155) DDR3 Motherboard **B3 REVISION**
(PCI Express LAN 10/100/1000 Fast Ethernet by Atheros AR8151.)

Kingston HyperX Blu 8GB (2x4GB) DDR3 PC3-10666C9 1333MHz Dual Channel Kit (KHX1333C9D3B1K2/8G)

Lan drivers installed fine and I have tried reinstalling them several times.

Ive also tried: Disabling/renabling the network adapter.
Reinstalling Windows 7
Putting in a random mac address
Changing security settings
uninstalling anti virus
checking bonjour wasnt interfering with the system
changing router settings to assign different ip
flushing dns
ipconfig renew/release
I've also tried changing to wireless from the lan connection i was using, all to no avail.

Another laptop seems to connect fine, so it seems like it's a problem with the install of windows 7. I did try an install of windows xp but got a 'psy.sys' error, which i presume is due to my mobo no longer supporting xp? In which case it seems that Windows 7 is my only option as I don't have a Vista disk.

Does anyone have any ideas? I'm fairly stumped, the only thing i can think of is perhaps downloading the lan drivers from the MSI website, but they dont seem to be updated from the originals I already have. Alternatively I was thinking I could try to do a static IP address but I can't seem to find my true DHCP server on my Virgin Super Hub panel. Also i've tried resetting the router and switching it off and on several times and should mention that i can access the router panel through my browser.

Any help would be really be appreciated as i need my pc up and running to work,

Thanks.




Dear All,

I am experiencing this windows 7 problem regarding internet connection. Every win7 pc is connected to the network but cannot access the web. This happens every morning, after sometime the icon with yellow exclamation point will disappear. But everyday I get complaints regarding that. The settings of my router's DNS is pointed to the Domain controller, w/c in my case is 192.168.23.4. Then the TCP/IP DNS setting on our DC is pointed to ISP's IP w/c is my case is 213.42.20.20(etisalat). Is this the correct configuration for this one, because only the windows 7 pc's are having trouble with regards to internet connection. Thanks in advance




I am using Windows 7 64-bit Home Premium. I have had this issue for a while and cannot seem to get it resolved. While the issue has not caused me any problems with working on my network/Internet, it is an annoying bug.

When I click on the Network icon on my system tray, I am told that there are no connections available. The Network icon itself though is showing that I am connected. I can access the Internet and my network without issue. I have two LAN adapters in my PC and the issue occurs with both of them. I have tried updating the drivers, uninstalling and reinstalling, disabling and enabling, all to no avail.

Going into the Network and Sharing Center shows that I am not connected to any network. If I pull up the Network Map, it shows my other computers, but that there is no connection to the Internet.

Does anyone have any idea how to fix this issue? I cannot seem to find a resolution on the 'net.

I've attached some screen shots as to what I see.

Thanks,

Looks like your connections get to the switch on the Router, or whatever you are using for an internet appliance, but something isn't correct for the internet connection.

Could you type the following in a command prompt window and attach the resulting text file, which should be on your desktop, using the paperclip on the advanced replies. Edit it for any personal info if you like.

ipconfig /all > %userprofile%Desktopipconfig.txt

You can paste this in a command window by right clicking and select paste.

Dear All,

I currently have a workgroup set up involving 4 computers with Windows 7. The network, prior to my modifications, worked very well, all of the computers were able to access each other's folders.

The only problem with this set up, however, was that there was no permissions set; more accurately, every user had access to every file.

I have now significantly changed the permissions for a folder on one of the computers (we will call it C1). Whereas there was an 'Everyone' user group, I have now deleted this, and there are remaining a 'Staff' user and a 'Manager' user. Now, none of the other computers can access the folder (although they can access other folders on C1 that have not had the permissions changed). All 4 computers have identical Staff and Manager accounts, with identical passwords.

Where the plot thickens, is that when I connect my XP laptop to the network, it will happily connect to the folder with the changed permissions, provided that I give either the 'Staff' or 'Manager' account with associated password.

The permissions are essential as this network is being used in an environment where free access to all files is undesireable.

Any assistance on this would be gratefully received.

Thanks in advance,

Ljubica




I have two PCs cabled directly to a Netgear WNDR4500 router. This morning, my Windows 7 PC had no network connection when I turned it on. These computers don't get moved, I wasn't messing with the cables beforehand. Everything was fine yesterday.

The Troubleshooter suggested I had a broken cable. I tried another cable, but it still would not work. I connected the Windows 7 machine to the same router connection my XP machine uses, but it still did not work.

Device Manager reports the Network Adapter is working properly. The system tray network icon reports "Not connected/No connections are available." The Troubleshooter reports, "A network cable is not properly plugged in or may be broken."

I tried disabling/enabling the Local Area Connection, but it still reports "Network cable unplugged."

My gut feeling is that the Ethernet jack on the motherboard is physically broken. But it blows my mind that it would break for no reason.

Could an automatic update of some sort disabled networking in a way that it only appears the cable is bad? Could the physical connection at the back of the machine spontaneously break?

I suppose I could go buy a network card, which would be cheaper than replacing the motherboard. I'm gonna get cleaned up and head to the store now.

Hi, I really cannot understand this and could do with some help.

Connectivity between SBS 2003 Server and Windows 7 Workstation is a problem, works and then does notw work. At a basic level ICMP a ping between does not work, request timed out.

If I ping another Machine on Network form Windows 7, i.e. XP PC no problem reply, if I ping the XP machine from Server no problem reply. Try between server and win 7 time out. (FIREWALL DISABLED)

I can resolve Name, I have used IP Address, I have rebuilt IP Stack, Cleared ARP, Installed Cisco VPN Client to manage MTU Packet Size, Changed Network card on servers, changed IP Address as well. Someting in Windows 7 is blocking connection to Server 2003, in some instances I get 1 packet response and then noting after I have rebooted or diabled and reenabled NIC Card.

Quick overview of Enviroment:
SBS 2003 SP2, Runnding Exchange and ISA (Cachine and Fikletring only not Firewall)
Cisco Catalyst 2960 Switch L2
Cisco ASA 5505

Desktops Are DX7900 Desktops, brand new and clean install of Win7. We did have XP in Nov,Dec while we waited for Win 7 Media to arrive and NO ISSUES WITH THE XP OS (SAME HARDWARE MICROSOFT!!!!!!!!!!!!!! WHAT THE HELLL!!!!!!!)

Anyone have any ideas on what the problem coudl be??

Thanks in advance.




Hello all,

I ran out of options to solve the following problem and I need your advice.

After return from standby or hibernating the network and internet connection did not re-establish.
The eventviewer ( I typed "eventvwr.exe" in the "Run" window) shows that the DHCP server( which's my router) does not provide an IP address for that computer. Other PC's ( 4 ) in the network are working well and showing not that behaviour and 2 of them are also on Win7.

I tried:
- static IP adress -> no success
- checked the router and the belonging address range -> no success
- disabling network adapter ( Network IC) in hardware manager when returning from standby -> works
- then re-enabling network adapter in hardware manager when returning from standby -> failure, Win7 freezes, hard boot
- same behaviour when I try with MPstandby handler and external batch file.
- in command console I tried different "powercfg" commands
- latest driver for network adapter
- unchecked in properties tab" this device can wake up...." -> no success

Network adapter can be disabled and enabled in hardware manager once a network connection is established but not when returning from Standby/Hibernate neither manually in hw manager nor with batch files using devcon.exe

Another strange behaviour: from normal boot the name of the network connection is "Lan-Verbindung" ( in English OS it is just "network") . But after return from sleep/standby the name changes into "Lan-Verbindung 2" ( or in English OS it would be "network 2")

Any other ideas ? I've searched and searched....

Thanks.

I have a question to anyone who can help. I have 2 wireless devices that stream my PC content to my LCD. Previously I was running Vista Enterprise and the devices could easily connect with WEP and I could stream content. Now with Windows 7 Ultimate, neither device can connect.

I have a Samsung 3600 Blu Ray with wireless connectivity that cannot connect and also a Verbatim Media Station Pro displaying the message "There is no shared directory on this PC. Check the status of the PC and try to connect again".
So far I have altered from Home to Work, from Homegroup to not Homegroup and nothing. Media streaming options have been switched on and off and I have also tried Network discovery is on. I have tried everything to my knowledge. Can anyone help who may know what the situation is and a possible solution. Oh and FYI I found a forum saying check the SSDP in services for discovery problems and it was fine.

Thanks in advance.




I have been using Windows 7 RC since it's release and on Saturday morning 9/12, my network stopped connecting to my AT&T Uverse router. I switched to my other hard drive having Windows XP 32-bit and that connected to the router just fine. I have a wired connection to it so I don't see what the problem is other than Windows 7 having the issue.

I spoke with AT&T Uverse Tech Support online and they basically just said Windows 7 is not supported by UVerse and didn't help. UVerse was working just fine the whole time with Windows 7 until Saturday morning when I woke up.

Detail of problem, when I log into Windows 7, the network icon in the tray shows a circle going for a few seconds then just has a ! mark. I check on troubleshoot but it doesn't help much. I tried disabling and reenabling the adapters and that didn't fix the problem, on top of uninstalling and letting windows reinstall the adapter.

When the ! is there, it says Unidentified Network or something of that nature. When I login to the router settings and look at the computers connected, it shows my computer connected by Ethernet!

What's wrong here and how do I correcet it? Router is showing my wired computer is connected, but windows 7 is showing a ! mark and says Unidentified Network and I can't do anything to correct it. Tried shutting off the firewall as well. Windows 7 was working just fine the night before w/o any changes, just next morning decided to stop connecting for no reason.

Please help, thanks!

from the XP machines I can now see vista and XP machine
I can access vista shares no problem
access using workgroup

Every so often i can see the windows 7 machine, and browse to my shares and access the windows 7 machine
and then everything stops ..... access denied ....

It should not be firewall ( Vista gets in and out)
it should not be the anti virus avast
from xp I can ping the machine seeing it in view workgroup does not seem relevant since I think that information is cached in xp ...

All machines have the same workgroup, TCP-IP setting -area 255.255.255.0 10.0.0.*
all machines have the same user and that user has same pw and is enabled for all shares individual and file access....
Ping works for all machines
internet works for all machines

Any idea ??? the fact I get connected without any problem every once and a wile bothers me a lot ....
as it takes days and a lot of fiddeling around to get it up again ....

any idea's I'm sruggling with the problem for days and lost a few XP machines ( reinstall..) but no success at all
nothing stable




Hi !
I'm new here and I must say I am a n00b when it comes to Windwos 7 connection methods, please explain it to me step by step if possible.

I have CANYON 11g AP Router which is conencted to this PC and a Windows 7 PC (my workstation). Last night the providers connection dropped so after finishing my work I didn't stand around to check if the internet will be back and closed it. This morning my girlfriend tried to unplug something and accidentally unplugged the router. Ever since that happened, this PC, running XP has no internet connection issues.

Unfortunately, the Windows 7 PC cannot connect to the Internet. I tried disabling and enabling, it ahs a clear connection towards "Multiple networks", but from there to the "Internet" it does not connect. I also tried a diagnostics and a firewall deactivation but still no luck.

My Netwpork meter gadgetr shows my Int. IP as 192.168.1.2 and my Ext. IP as NO CONNECTION.

When I try to connect to the internet it appears that Mozilla finds the website but cannot conenct to it. At least that's what I think, since it is stuck on "Connecting" and not on "Looking up".

Ipconfig does not work, it only shows the window for a brief second, then auto closes.

Any ideas how to fix this thing ?

Note: Both IPv4 and IPv6 are set to find IP and DNS address automatically.

IPv4 connectivity: No Internet Access
IPv6 connectivity: No Network Access




I have a 3 PC network (no WEP or WPA security) attached to a Thomson 760W wireless router with the latest Firmware (6.3.27.2)
2 PCs (Angua and Carrot - dont ask!!) run XP SP3 (all latest updates); 1 PC runs Windows 7 Ultimate (all latest updates)
There are no active firewalls
When all PCs have a wired ethernet connection to the network, everything (shares etc) works fine
When the W7 PC is connected to the network wirelessly
W7 can access the shares on Carrot
cannot access the shares on Angua (). I suspect it cannot even see Angua and the reference is there from an earlier wired connection
cannot access a network drive that points to a share on Angua
Angua can access the shares on W7

A 4th PC running XP SP3 (not a normal part of the network) connected wirelessly can access Angua and can be accessed by Angua and the W7.

W7 can ping Angua and the 4th PC (time=1ms)
And Angua can ping the W7

I have the same items showing under the Wireless network Connection properties on both Angua and Carrot. They are
Client for MS Networks
File and Printer sharing
QoS packet scheduler
TCP/IP

Under Network Connction details everything seems to be OK. There is an IP address and NetBIOS over TCPIP says Yes
The Troubleshooter (Shared Folders) quite unhelpfully said 'Couldn't identify the problem' and under details "no issues detected" but attempts to access a share in explorere are met with Anguafolder is not accessible. You might not have permissions etc etc"
(When hooked up wired W7 reports the permissions on the shared folder as everyone)

So it seems that is is something to do with the combination of settings on W7 and Angua
So please, what do I have to do to get the wireless component of this network working remembering that
1. it works wired and not wirelessly
2. it works on two XP machines but not on a third.




I have an Asus 1005ha netbook running Windows 7 starter that connects fine to my airport express network. The netbook finds my Canon iP5000 printer which is connected to my imac with a usb. The imac connects wirelessly to my network. I have updated the driver which shows up, but I can not print. I have tried running the printer through Bonjour for Windows but can not complete the process due to a message of "You do not have sufficient access to your computer to connect to the selected printer."

I also have an Epson cx7400 which is connected directly to my airport . . . no luck there either.

Any help you can give me would be appreciated.




I installed Windows 7 on 2 machines that were formerly loaded with XP pro. They are part of an Domain with a Server 2003 Domain controller, 2 terminal servers, and a Linux File server. We are running AD, and the XP machines could browse to domain Shares on all the servers by Name.

When I try to navigate to a domain share, (by share name) from either of the 2 Windows 7 machines, I am unable to authenticate and connect to the share via any account at all. The error says that the username or login is invalid, but it does not say that the share could not be found. Oddly, I am able to connect to the same shares via IP, with no authentication issues at all. All of the remaining XP machines are still able to connect with no issues at all.

Prior to the upgrade, both Windows 7 machines were able to connect to the shares. Both machines are joined to the domain, have DHCP reservations that are active, and registered in AD. Both Windows 7 machines can browse to each other but cannot browse to any XP or server share on the domain by share name.

On the Windows 7 machines, Network Discovery is installed, File and print sharing is enabled, and I have tried disabling the Windows firewall with no effect.

Does anybody have any ideas? Any help would be appreciated.




Hi,

I am having trouble connecting my girlfriends laptop to the internet using her Windows 7 laptop via a Dlink router with Virgin Media. The laptop previously had Windows Vista installed but I recently upgraded it to Windows 7. For about 2 weeks the laptop connected to the wireless router fine, but stopped working about 4 days ago for some unknown reason out of the blue.

We have tried various methods to fix it, including disabling the wireless network adapter and enabling it again, we have tried updating the driver for the adapter but we get a message saying that the driver currently installed is the latest driver. It also won't let me roll back to the previous driver as that option is faded out in the properties box.

I have took her laptop to my house today to try and connect it to my router (which is also with Virgin and is working fine on my computers at my house) and the laptop won't let me connect to the network and it keeps saying there are no network connections available. I understand that usually it displays a list of connections you can log on to, but the laptop is not finding any connections at all.

On Thursday we attempted to connect to the internet by plugging in the blue wire that came with the router and that works fine. It's just it will not connect wirelessly. What really baffles us with this problem is that it worked fine for a couple of weeks then suddenly stopped working. Could it be an update that was installed that has caused the problem perhaps?

I have also tried using System Restore but that hasn't fixed the problem either.

The wireless adapter is called: Atheros AR5005G Wirelss Network Adapter.

Please help as my girlfriend needs her Facebook fix and is very close to throwing her laptop out of the window




Dell Studio Desktop Computer
Windows 7 SP1
Realtek PCIe GBE Family Controller
Netgear DG834 Modem/Router

I have a problem with my home network that I have been trying to solve for weeks. Hopefully someone will be able to help (thanks in advance).

Windows 7 reports that I have no network connection (see image) but I DO have a network connection and I can also surf the Internet. I can see and share files on a Compaq computer running Windows XP from my Dell computer and vice versa (albeit only the Dell’s public folder from the Compaq computer). I tried to share other folders but Windows informs me that I would need to change to a “Home and Work” profile and not a “Public” profile.

When I try to do so I am informed that I have no network connection but as I said before I clearly do have a connection. I then tried to fix the problem using the settings in the Network and Sharing Center but when I try to turn on network discovery for the Home and Work profile it does not “stick” but simply reverts back to the “Public” profile.

The Windows 7 network map also gives odd readings (see image). It shows the connection to my printer but states that it cannot map to my Compaq computer. Furthermore, it shows that I do not have a connection to the Internet – but I DO.

I would appreciate help in sorting these problems out. Attached Thumbnails     Share Share this post on Digg Del.icio.us Technorati Twitter

Launch Windows Command Prompt

Type: ipconfig /all

Please specify the DNS servers that come up.

Example:

DNS Servers . . . . . . . . . . . : 8.8.8.8
208.67.222.222
207.67.220.220

(You will need to scroll up in most cases)

What you want to do, is try switching to manual DNS.

To set your DNS servers manually, see:

Using Google Public DNS

I recommend this because sometimes your router will not pass along DNS information properly when DHCP is enabled and this issue appears. The answer is not to disable DHCP, but to override DNS with custom settings. In this case you could use Google's public DNS and determine if the problem still occurs. The DNS servers I have listed above are Google and OpenDNS, both of which are highly reliable and unlikely to cause difficulties. Please let me know if you find this to be a useful remedy to the issue.




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).

The
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
LAN).

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.




On finding that Windows 7 has a built in VPN client, I've been trying to get it to connect to our Cisco PIX. However, so far no luck. Our Cisco VPN client will not operate on Vista or Windows 7. The tunnelling protocol is IPSec/UDP. I am not a networking expert by a long shot. I just thought that I could use the settings we have on our Cisco VPN client. So far no luck.

Any thoughts or suggestions would be greatly appreciated.

Thanks a lot.

My machine is dual boot Win 7 x32 and Linux. I'm using a wired Broadcom 400x integrated NIC with a Motorla cable modem. I've been using this setup of about 5 months with Win7.

There is only one computer connected and I have no wireless/router. In the middle of surfing on the Win OS, my connection dropped and the computer froze up, forcing me to do a cold boot.
When rebooting to windows, I got a red X in the sys tray. No Local area connection, no network connectivity.

I booted again, into Linux this time, and it all works fine, leading me to believe this is a software issue for sure. I also downloaded and ran the broadcom diagnostic utility for my NIC and all the tests passed.

The "Network and Sharing" screen shows no connection, (just diagram of computerXGlobe) but the properties screen in the device manager shows it's connected with no problem, other than 0 packets transferred. It also reports no problem with the driver, but I re-installed it anyway, using the latest available.

Most mysterious of all is that running ipconfig/all doesn't show the card at all. It's completely missing. (see below) The only thing it returns is the Teredo Tunneling Pseudo Interface and a 6to4 adapter. Both are reported "Media Disconnected" and neither has a DNS suffix, IP address or Default Gateway listed. Nor do either of these show up in the Device manager under network adapters.

The property screen that comes up when you right-click the Local Area Connection on the "Network and Sharing" screen and double click the IPV4 line returns the message "Windows couldn't automatically bind the IP protocol stack to the network adapter".
IPV4 and IPV6 show no connectivity. Looking through the event log at the time of the crash confirms the problem (see below).
That's the best and only hint I've gotten so far as to what is going wrong, but I can't find a clue of how to correct it.

The network troubleshooter acts like it is resolving the problem but is useless in the end and just reports that my network card is "experiencing problems"....Duh!

This is what I've done so far, (not necessarily in this order):

Ran Farbar (shows no connection to net, but localhost, Yahoo and Google accessible, see log below)
Installed newest drivers I could find.
Power off/on the modem and rebooted (warm and cold) multiple times.
Ran a sfc /scannow
Did full virus and malware scans
Reset winsock
Reset IPV4 and IPV6 TCP/IP stacks to installation defaults
Cleared and registered DNS cache
Release and renew current IP address
Checked Hosts file for any strange entries.
Checked all services and process lists for any remnants of any possibly interfering process.
Repeatedly boot into safe mode with network connectivity.
Uninstalled network card in device manager and reboot, cold and warm.
Unchecked IPV6 and both topographical protocols, one at a time, and rebooted after each change.
Uninstalled AVG, Comodo Firewall, Open VPN and Wireshark, all of which were present for a week or more when everything was running just fine.
Spit, cursed, rendered my clothes and tore at my hair.
Spent 17 hours on google trying to figure this out. (Running Linux)

PLEASE!!! If anyone has any idea what's going on here, please chime in. I have wore out my google finger and have not found anything like what I'm experiencing here. At least most people get something reported in their ipconfig window.
I can't use a system restore because, evidently, the VSS shadow service has been turned off lately.

In the event log, there are references to the "RootCauseGUID. I Found 3 instances of them under the same sub-key in the registry. PC-Tools reports them as having/being invalid D-Values of 2 bytes.
The "RepairGUID"s don't exist at all in the registry. Is there any significance to this, or to the mention of "70 seconds Required"? If I didn't know better, I'd think this could be fixed in 70 seconds by editing these 2 invalid "RootCauseGUID"s.

Anyway, here are the results of some of the logs, etc. that I have generated. I desperately need to get this fixed. I can't do a restore because my VSS was disabled. I can't even do a re-install because the Mickey Mouse outfit I bought this machine from never gave me a disc or any way to reinstall it. All I have is a 6 month old img. file iif worse comes to worse.

BTW, I had been running AVG AV and Comodo FW for a month before this happened. I uninstalled them and scoured the computer for any remaning remnants. I still suspect they may have changed something in the registry that "stuck" when it crashed. But that's 100% speculation.
