Dell 600m Suddenly lost internet connection

[Jeephippy]

My Dell 600m's wireless was working fine earlier this morning, when I came back home this evening, it will neither connect wirelessly nor through a lan line. It says limited or no connectivity either way. I have tried:

Repairing the connection

Reseting the Winsock on cmd

Pinging the cmd ip address


Any help would be great, I am stumped!!!!

Also, if I plug a cable directly into the back of the modem I can access the internet but still get the limited or no connectivity...

Other computers work wirelessly just fine from the router...

I'll go out on a limb here. Restart your laptop with it plugged into the router.

What OS?

One thing to try,
Make sure your network settings on the laptop are correct. Run an IPCONFIG -RLEASE, IPCONFIG- RENEW
Try pinging 127.0.0.1

If none of this helps, uninstall the network card and re-install it.
