Good morning. *I wasn't sure whether to post this in the Networking or Vista category. *As is so often the case with
idiosyncratic system behavior, I suspect that Vista may be at the root of the problem, so it seems appropriate to place it
I have an HP Pavilion pc, with Vista Home Premium, version 6.
I experienced a loss of internet
connectivity a few days ago.* An ISP tech connected me to a new v LAN, which required a new IP address. *
entered the new info (IP address and Default gateway) in the Local Area Connection "Properties" window, but still could not
connect.* I looked at the Local Area Connection "Details" window, and saw that it displayed the old IP address info.* I went
back into the "Properties" window, and saw that the Default gateway fields were blank. *
After some trial and
error, I established an odd work-around, but it is effective only until I log off or reboot.* I was able to get connected by
re-entering the new Default gateway in the "Properties" window, then going to the "Advanced TCP/IP Settings" window, removing
the new IP address from the list.* This left the old IP address as the only address in the list.* I then re-added the new IP
address, which put it second on the address list (under the old address).* In the "Details" window, the IP address and
Default gateway info was then correct. * I saved these changes, and was able to connect to the Internet.
the aforementioned settings changes will be lost upon log-off or shut-down. Once logged back in, the Local Area Connection
info reflects the old IP address info again.
The only other clue I observed was that on the first day that I tried
the new IP address, an installation progress window appeared a couple of times, indicating that an attempt to install an
*"Unidentified" item was being made.* Later, a failure message appeared indicating that driver(s) for the Microsoft 6to4
Adapter had failed to install.
I went to the Device Manager, clicked on the referenced Adapter, and the
"Properties" window indicated that the device was not working properly.* I uninstalled that adapter, and then installed
another (I found Microsoft 6to4 Adapter in the"Add legacy hardware" list.) The "Properties" window for the new adapter
indicates that it is working properly.
This did not fix the problem.* I think that the adapter I installed may be
an older version than the one I removed - the newly-installed one has a Driver Date of 6/21/2006.* The one I removed may have
come from an Update. *(I checked the available Windows Updates, but there was none for an adapter.)
problem with IP address info be related to this Microsoft 6to4 Adapter?* If so, could/should I get a more recent version?*
Can this be downloaded from somewhere?
If the adapter is not the culprit, what else might be?
for any input.
