Having problems on dv6 6020st wifi (Broadcom)

[EzerchE]

Hello, i am having some connections problem with my Broadcom 4313GN Wifi card. Especially after the waking up from Sleep mode, i couldnt connect to any wireless network. If i press wifi key several times it could barely connect, and sometimes it connects with 2mbit.

I have latest drivers installed (5.100.82.82), also i have tried older versions too. i have formatted my computer too, windows 7 x64 home premium is installed. Is there anyone having the same problem or do you have any suggestions about it?
