I have a Dell Latitude D531 laptop with a Broadcom BCM4311 wireless card running Linux Mint 14 (Nadia). I can get internet just fine with an ethernet cable, but that's about it. I push the wireless button and nothing happens. I went to Software Sources, selected Additional Drivers, and selected "Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary)" and still nothing.
Mint seems to be able to detect the BCM4311, but won't work with it. Any help?
