I've got a BCM4311 and even if it's detected, it doesn't detect any wireless networks. Strangely, led is kinda 'bright orange', which suggests me both red and blue leds are lit.
This isn't expected, as it's just blue when working or red when not working.

Some people said it should work on Leo4allv2, but I'm really not interested on switching just to check WiFi. :P
