I had similar issue with Thinkpad E440 using Intel Wireless N 7260 in Windows 8.1 64 bit. Sporadic disconnecting and limited connection almost every 10 secs. Have been tried with workaround in Microsoft Community and here, but the problem still persist.
Tried to clean install Windows 8 instead of 8.1, the problem exists every 5 mins. Already tried all drivers (from lenovo, intel, latest one 17.0) but still.
I haven't tried in Windows 7, in my opinion based on the community said, it will be worked in 7.
Is this related to Intel wireless hardware fault, Microsoft 8.1 issues, or Intel driver miscompatibility? Everyone had similar issue with cross branded laptop. Dell, Asus, Lenovo, HP which using this wireless card.
What can I do then?
