all was oke with beta win 7 (7100 or smth like that)
all works perfectly with my other asus comp. with XP
i've tried all drivers for aheros ar5b91,but that don't makes any difference at all

what to do?

what is better in beta win 7 ultimate than in build 7600?

the same router and the same adapter,but worked in beta & don't works now.
