Everything was fine yesterday. But today, I'm unable to connect to the Internet on my Vista desktop. The desktop is connected to the router via an Ethernet cable.

My laptop and PS3 still connects fine. When I disconnected the laptop and put the Ethernet cable from the router into the laptop. I could get a connection no problem.

When I move the mouse over the connection on my Vista laptop it says (Unidentified Network). I've tried repairing etc.

When I go into CMD and type ipconfig it says:

Autoconfig IPv4 Address: 169.254.235.155.
Submask: 255.255.0.0
Default Gateway: is blank

The IP should be something like 192.168.1.60. I set the Vista comp a static IP. Put in the right submask and default Gateway. But it didn't work. So I put the settings back to automatic.

I'm also unable to log into the router with the Vista desktop. I can log into it with the laptop though.

There is nothing wrong with the Internet. It has to be some kind of setting on the Vista machine. Anyone got any ideas?

The Router is a SpeedTouch 585. AOL internet.

Hey bud,

Please uninstall IPv6:
  • Select Start
  • Type cmd in the Start Search field
  • Right-click on the cmd program and select Run as administrator
  • In the new command prompt window, type netsh int ipv6 uninstall
  • Once the above command completes, type ipconfig /flushdns
  • Restart your computer; are you able to connect to the Internet?
If not, please post a full ipconfig /all:
  • Press Start
  • In the Start Search field type cmd and press the ENTER key
  • In the new command prompt window, type ipconfig /all > C:\ipconfig.txt
  • Navigate to your C: drive and open the text file ipconfig.txt -- please copy/paste the contents of this file into your next response.

This problem has come back today, although the desktop pc was reformatted and XP installed.

I've done what Dan said to do. Heres my log:

Well, I fixed it myself. I came to the conclusion that the network adapter on the motherboard wasn't working. I installed a separate network card from another computer, and that worked fine.

I took a closer look at the network adapter build into the motherboard using a torch. Right at the back of the socket was a small black piece of grit. No idea how it got in there. I managed to clean it out. Plugged the network cable from my router back in to the network adapter and it worked.
