Hi, I bought my laptop Feb'15. From the past one month my laptop wifi adapter is crashing suddenly. It shows that it is active in the adapter settings but doesn't connect to any network or even show available networks. When I try disabling and re-enabling the adapter my laptop hangs or I get a BSOD. I have tried updating the drivers. Please help !!
