Intel AC 7260 HMWWB Installation\operation problems : Acer Aspire 5755-9674

Hello.

I have a problem correctly installing and running the adapter.

The installation goes well, and the card functions ok, but when it's in the laptop, it creates problems as such:

1. BIOS is slow. It takes from 2 to 5 seconds to respond on commands (even left or right arrow command).

2. Windows boot screen freezes for 15-20 seconds (no animation at all, then, after 20 sec the 4 lights start moving, and Windows boots).

3. Windows shows transmit speeds incorrectly: instead of 5 MBps - 15-20. (Server laptop is able to operate only up to 5 MB speeds).

 

Chipset is Intel Cougar Point HM65. BIOS is the last version provided by ACER. Chipset driver is up to date too.

OS is Windows 7 64bit.

 

I've tested all my hardware (CPU, RAM, HDD, SSD), all of which works fine.

Also I have an Intel 6205 WIFI adapter (native) which works PERFECTLY too. (in this case, - no A,B,C problems described before)

 

Please help find the solution.
