I just bought a brand new Dell Vostro with Ubuntu pre-installed.

Fresh out of the box the wireless would connect to the router but would not connect to and surf the net.

Upgraded to latest version, checked for drivers, still the same-- will connect to Router, but will not surf the net.

The error page reads: "Server not found"
Firefox cannot find the server at www.google.com
Check the address for typing errors...
...check your computer's network connection
...make sure Firefox is permitted to access the web

I've double and triple checked the wireless settings until I'm blue in the face. The new Vostro will connect to the wireless network, it simply won't surf the net.

I hope someone has an answer to this horribly frustrating dilemma.
