My Vista computer shows "Unidentified Network" and I have lost Internet.

Windows Vista Business was working fine then all of a sudden it is showing a Unidentified Network and I have lost all Internet access.

When I check Internet connection details it states that the Autoconfiguration IPv4 showing a 169 IP address which can't be good.

The setup is high speed Comcast connection to a router with DHCP set and connected to my laptop through a wired and wireless connection.

It has been a couple of months since this thread started. If you have an Unidentified Connection on both router and on the modem, and since (per earlier) the fault started and affected both wired and wireless NIC's, and since you did the TCP/IP repari, it may be time to rebuild your OS.  ...

So you have a problem with Vista. Two hardware NIC's don't fail at the same instant. You could have some strange motherboard problem, but then the PC likely would not run.

Try a TCP/IP repair. Also scan thoroughly for malware and viruses. .... T

It started the instant that the router changed to "Unidentified network".

I have done every TCP/IP repair multiple times without success.

As you asked I did a virus check and it came up clean.

OK - thanks.  You could have a router problem. If you have a friend with a laptop, you can easily check this. Otherwise, you can try a hard router reset and see if that helps. Even in a router, wired LAN and wireless LAN are different so both going out at the same time is also strange. .... T

Another thing you can do is take out the router, hook up the computer to the modem directly and see if that works. If so, you know it is the router. .... T

The Unidentified Connection continues whether I use the router or go direct to the Internet....
