Wireless connects, but no data?

[ander111]

Hi guys,

I've installed Ubuntu 11.04 on my Toshiba NB255 netbook. I'm happy to find that audio now works, and I can control the screen brightness (two problems that kept me from using Ubuntu 10).

But now my wireless adapter doesn't work. Well, it sort of works... The router accepts our security key, and Ubuntu says I'm connected—but I can't get anything to load in Firefox.

Wireless has worked fine with Windows 7 (which is maddeningly slow, though, which is why I'd like to replace it with Linux, see) and with Linux Mint 9 (which unfortunately didn't handle power well, and cut my battery time in half).

I've searched and found many posts from people who couldn't connect—but once they connected, they had no problems. So this seems a bit different.

Where should I start? I'll be glad to post any info here you wish. Thanks for your help.

Well, 48 views and no suggestions... I'm glad you're reading my post, though. :?)

I saw another thread from someone with wireless problems, and they posted the output of these commands—so in case it helps:

lo no wireless extensions.

eth0 no wireless extensions.

The icon "throbs" but nothing happens. When I run it from a command line ("firefox"), it does run, but then this message appears in the command window:

Well, I just tried Linux Mint 11 (http://%22http://blog.linuxmint.com/?p=1760) and everything works fine, including wireless. Funny, it's based on Ubuntu—I guess LM's developers have done some extra tweaking.

So, thanks anyway. :?|
