I'm running into the exact same issue. I've checked some other forums regarding the driver and it seems like there are quite a few people experiencing this issue. Has anyone here heard of any fixes yet? I'm kind of trolling everywhere hoping that there's some magic somewhere ;-) I need this wireless working mostly as a matter of convenience for work :-/
