Intel 7260ac wireless card 'off'

[gkaly]

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

I understand that the WiFi radio will not turn on after installing the Intel® Dual Band Wireless-AC 7260.

Some system manufacturers provide a software switch besides the hardware switch you already know. I suggest you checking with the manufacturer if your model requires any other software tool or relevant (BIOS) updates.

There are a few things to consider when installing or upgrading a half mini PCI Express wireless adapter:

• Just like any other device, not all wireless adapters are physically and electrically compatible with all systems.
• The system BIOS could be designed to accept certain wireless adapter models only.
• The installation of these adapters is subject to country-specific regulatory approvals which include the system, wireless adapter and antennas.

You may also contact your http://www.intel.com/support/oems.htm system manufacturer in order to obtain a list of validated wireless adapter models that are compatible with your system.
