I’ve just spent 3 hours playing around with trying to get wireless to play nicely.
Thankfully, after attempting various HOW-TOs that are out there, I managed to use the Windows drivers from the Linksys FTP site with ndiswrapper.
I also installed network-manager to get the whole thing rolling, and the wifi worked immediately after the final reboot.
The main issue with using the NDIS driver is to add the naive Broadcom driver to the blacklist to prevent it loading in, as it will interfere otherwise. If you do not, you get this error:
bcm43xx Microcode “bcm43xx_microcode5.fw” not available or load failed
Well, I’d better get to bed.
