Just started using Ubuntu a few days ago, thought I'd give it a try. However, I can't connect to wireless networks, which makes it unusable if I cant fix the problem. My card wireless card appears to be working, in that I can see wireless networks I'm in range of, and their respective signal strengths. However, whenever I try to connect to one, it tries for awhile, then fails to do anything. I've tried it on the networks at my Mom's, Dad's, and Aunt's houses, all of which work fine when I plug in wired. I really don't want to go back to windows, but I need wireless to work. I'll check this thread fairly regularly, so if you need any additional info just ask.

EDIT: Typoed the title, should say "Belkin"

could you give the output of
JUST IN CASE you're really new, open a terminal, and type that. :-D

It sounds like it isn't getting an IP address through DHCP.

Open up System > Administration > Network and see if your card even appears in the list of interfaces. Make sure it isn't set to "Roaming Mode" which doesn't seem to work very well (at least for mine).

Edit the properties for the card and restart the card. That should hopefully fix the problem.

The command sudo ifconfig in a terminal will show you active interfaces and their IP address if any.

Do you have a Broadcom internal wireless card by any chance? If so I found a solution that worked for me.

My Belkin wireless card does the same as yours - detecting signals, but could only log on for about 10 seconds. I think we need to configure it properly, somehow.

Hey, thanks for the replies, managed to get it working though. This: http://ubuntuforums.org/s howthread.php?t=400236 solved the problem for me.
