Hello,
i was checking lots of forums but couldn't solve my problem, so want to consult with experts
my wireless disconnects frequently, on battery more frequent, on a/c less frequent, maybe every hour or every two hours. and it doesnt work to disable wireless signal and enable again, the only thing helps is to restart my laptop. then connection is back.
here is some info if needed:
