I've just finished installing & tweaking this new driver, and I like what I see so far!
Be sure that during your install, you enable the last 3 options if you want them... These include some Admin controls that give you more control over how logons & connections are managed in connection with Windows Login. ALso, I was quickly able to hone in on Power Management options that have already boosted my signal at the home office. Very nice!
I'm not sure what "promiscuous mode" is, but trust that flibber will enlighten us!
