Comment 4 for bug 99054

Did you try to blacklist bcm43xx before trying to set-up ndiswrapper? If not, ndiswrapper will fail. In general I would recommend at least trying bcm43xx again, ndiswrapper caused a lot of troubles (at least for me).

Since kernel 2.6.20 the bcm43xx module is much more stable than it was in earlier releases. OK, at the moment still not a lot more than 11Mbit/s, but at least you'll get a stable connection.
