Nice tutorial!
I am assuming that you are running a fresh BT4 Pre Final
Which is weird, because I only just did a fresh install and tried to compile the driver but I run into heaps (and I mean heaps) of build errors.
Did you specify something else? A specific compiler?
If you know what might be going on I can put the log up?




Best stick with the madwifi drivers until it becomes a bit more stable.
