I've got an Ubuntu 14.10 live usb I'm fiddling with. At some point in the 12.xx cycle my wifi started getting funky in Ubuntu, and it's never recovered.
I've got a mid-2010 Macbook pro (7.1) using the b43 open source driver. With the STA proprietary driver I don't list any networks, with b43 I can at least see what's around me. HOWEVER I can't join any of them. I live in military housing and the only network available to me is an open network that is mac-filtered via a logon after joining, I don't know if I can for some reason join encrypted networks. Does anyone have any debugging suggestions? I'd love to start using Ubuntu again.
