Cannot connect to wireless network in Ubuntu 9.04 (Jaunty)

amac26629 · 07-26-2009, 12:53 AM

Hello everyone,

I just installed my first Linux, Ubuntu 9.04, earlier this week and cannot connect to wireless internet. I don't know if wired internet works as I do not have access to it (this message is sent from Windows XP from the wireless network I want to connect to under Ubuntu). I am using an Intel PRO/Wireless 2200BG wireless network card. It detects the network I want to connect to, but when I try to access it and enter the password, I am confronted with a message that the network is secured and requires a password. Every time I enter the password, the same message pops up again after the connection cannot be made. I think the encryption is WEP, but I'm not sure.

I posted this in the hardware section because I think the problem is with how Ubuntu is interfacing with my network card, but I'm not sure.

Here are some commands I entered and the output they produced:

Ubuntu looks really cool and I'd love to learn how to use it, but it won't do me much good if I can't access the net. I'd appreciate any help.

Thanks,

Try to install wicd

Thanks, repo. I installed wicd, and it seems to have done some good. I can connect to unencrypted wireless and wired internet, but the encrypted wireless still isn't working. If anybody is having the same problem I am and interested in seeing a resolution, I moved my question to the wicd forums since they probably know how to debug the software better than anybody else. Hopefully everything will be fixed soon: http://wicd.net/punbb/viewtopic.php?id=639.
