I installed Ubuntu on a partition of my MacBook Pro. Wireless connections work fine when I switch to OSX, but the wireless networks are not even detected when I boot Ubuntu. I installed Wicd as a new network manager, but I'm still having the same problem. Ubuntu works on a wired connection though. I have searched the web for a solution... similar questions have been asked but I have not been able to find a way to fix this problem. Any help would be greatly appreciated.
