wlan0 does not exist even with wireless driver and ndiswrapper installed

Question

I have a Linksys AE1000 USB wireless adapter. I have installed the driver using Windows Wireless Driver and have run ndiswrapper. I get the wireless icon at the top right, but it detects no signal and there is no wlan0 device defined.

I am running 12.04 LTS. How do I get this crazy thing to work? The chipset is Broadcom BCM4311.

Answer 1

Make sure that the drivers have been unpacked into /lib/firmware/ and then type

sudo modprobe b43 

You might have to wait a couple seconds.
