Hi everyone. I have recently bought a new pc, and I installed, for wifi, a TP-LINK WN951N wlan card. It worked fine at first, but then it started acting weird: it connects to a network ( I got 2 in my house, because it's big, both connected to the same router, one with a new n airport express and one with an old g airport express), it works fine for some time, but then (after sometime between 2-3 and 60 minutes), it stops working, no matter what I do. Both of my networks don't work (even tough windows doesn't report any issue or whatsoever), and even if I connect to my phone's wifi hotspot, i have the same problem ( so it's not my network's fault, it's something in the WLAN card). The only thing I can do is to use windows network diagnostic tool, which "resets my network card" (that's what appear in the diagnostic window, at least), giving me some extra time, before re-having the same issue. I tried downloading the latest drivers from TP-LINK website (I have version 3), but the issue still remains. Windows recognizes the card as "Qualcomm Atheros AR922X Wireless network adapter", so I tried also downloading the Qualcomm's latest drivers, but nothing happened. Can anyone please help me? thanks a lot (sorry for the bad english)

EDIT: I forgot to mention that i'm using Windows 8
