So I just installed Ubuntu 16.04, and I'm having a couple of problems. The biggest one so far is that, for some bizarre reason, the bcmwl-kernel-source driver does not work at all for it. When I install it, the wireless doesn't show a single connection, and I have to resort to a wired connection.
I have gotten around this using the second solution here, which involves uninstalling the bcmwl-kernel-source driver and installing firmware, among other things; however, while the wireless does work, it drops out very, very often, and is slow and horrible.
Any ideas? I'm using a MacBook Pro 7,1, and the wireless card is 14e4:432b. Any help would be appreciated.
