I have a netgear X4 R7500 802.1 g/n/ac router with two access points (one ac and one n)

network-manager can SEE all the wifi AP (both n and ac) BUT can only connect to the n. When I try to connect to ac, it asks me for password, then after some time request the password again. At this moment I can't connect to any AP unless I enter sudo network-manager restart .

Basically I am stuck with 802.11n now.I also bought other WIFI USB dongles with 802.11ac but none were working correctly.
