Wireless Not connecting

Hopefully I have the correct forum, if feel free to let me know.

I just installed the newest version on to an HP Desktop with wireless built in. I entered everything for the wireless but am not connecting. THe unit works with windows7 so I know it's good. The wireless provider is AT&T, a 2wire device. I must be missing something but unfortunately since this is my first go round with Linux I can't find what it is and not sure if there is any logs to check that might give a hint as to where the problem lies.

Anybody have any suggestions besides the obvious? I've tried multiple attempts and from the router end it also looks like it isn;t even trying to connect.

Thanks,

Geoff
