As it says in the wiki, an interface with the 0x4328 ID is not
supported. You need to use the Broadcom wl driver, which is
proprietary. I suppose that this was the "Restricted Driver" from
Ubuntu. Your other option would be to get the driver from Broadcom and
build it on your system.

We are in the process of doing the reverse engineering on the N-PHY
devices, but it does not have high priority at the moment.
