Intel My Wifi Technology Download Windows 7 64 Bit

Probably its not a hardware problem, and its not QoS problem. I have the same issue on my new intel powered laptop (Lenovo thinkpad P53), with newest wifi driver. wifi card loosing conection while im just pinging my router. and its not a router priblem. the same issue with any wifi acces point what i tested. on ubuntu os it works pretty well.
