The Intel® Dual Band Wireless-AC 8260 should work well in 802.11n networks, however, it is capable of using 802.11ac.

thanks for the help. I solved it. After two sleepless nights i brought my new ( two days old ) computer to service. The problem was not because of drivers or no 802,11n option. The problem was that wireless antenna was not connected to wireless adapter.... Good job lenovo factory . Service connected antenna and now it works perfect without any drivers update or something
