Hi,
I have an acer aspire 6920g laptop.
A few weeks ago decided to update to win 8.1
Since the updated I randomly received a system error message 'Your system noticed a problem and will restart :driver irql not less or equal (netwlv64.sys)'
I searched on the net and find out that my wireless card is probably not supported on win 8.1 (intel 4965AGN), so I bought an intel 7260ac.
When I installed it in and tthe windows was alive I wasn't able to tun on the card. what I mean that the option was greyed out in the network selection side menu(so no chance to switch it)and the test said that my wireless card is off. I have a physical button to turn on/off wireless conections. I tried to reinstall the windows but same result.
I'm out of ideas... if anyone can help me it would be more than welcomed.
Thanks
