Vista - "Unidentified network", local but no internet connection.

Using Vista Ultimate. Just this past Sunday had networking problem start.

On starting Vista, there is no internet connectivity. Network and Sharing
Center shows two networks--Home and Unidentified Network. The only fix that
works is to disable the Unidentified Network , then go to Device Manager and
disable my network card. Then in the graphic of my Home computer and the
internet, click on the red X and go ahead with the Diagnose and Repair dialog
that displays. It tells me that my LAN card is disabled, do I want to enable
it? Click Yes, and it repairs. I can access the internet again.

I reset the cable modem and changed cables, but that didn't solve this
problem.

Does anyoen have any advice?

please post the text output of ipconfig /all from an elevated
command prompt.

It could be the incompatible issue. This post may help,

I don't think it is motherboard or chip incompatibility. It was working fine
for months, and only started this behaviour after this weekend's WGA server
outage.

there is no default gateway in the "bad" state.

I wonder if

apply?

I downloaded the update, but when I started it, Windows tells me that "This
update does not apply to your system."

could you double check which you downloaded as there are 2 - one for
x86 and one for x64? also, please check control panel, programs and
see if this has already been applied.

As said this is the router/modem/NIC incompatible with the Vista. When the computer turn on IPv6 can't receive the default gateway which is 0.0.0.0 so that you can not access the Internet. However, afar repairing, the default gateway is setup to Default Gateway . . . . . . . .. . : 75.68.168.1. the solution could be as simple as sizable the IPv6.
