I think the correct driver is broadcom-wl
You have two options:

  1. Install the kernel module matching your kernel. For example, in my case:
    sudo pacman -S linux54-broadcom-wl

  2. Install the dkms kernel module:
    sudo pacman -S dkms linux54-headers broadcom-wl-dkms
    (note linux54-headers is kernel specific)

The advantage of 1 is being faster to install and update. The advantage of 2 is the module updating itself automatically upon each kernel update or change. There is no difference concerning performance.
