Just did a clean install of Ubuntu 14.04 on an HP laptop with a Broadcom 4311 wireless card. I've installed the following packages in an attempt to find the driver for it.
b43-fwcutter firmware-b43-installer linux-firmware-nonfree
The wireless card worked fine in Ubuntu 13.10, but in Ubuntu 14.04 it doesn't even show up in the network manager, and toggling the hardware switch doesn't do anything. I installed "sysinfo" and it properly identifies the wireless card model, but for some reason installing the driver doesn't seem to have gotten it to work.
I've done some searching for various wireless tutorials, but most of them seem to pertain to helping people find a driver. I've got the driver, it's the same one I used in the previous version of Ubuntu, it just isn't working any more, :-(
