Model # C7000v2.

Nighthawk Modem router model #C7000v2. Having trouble connecting my devices to router all of a sudden. Laptops are in and out of connection, cell phones are completely not connected and will not connect. Anyone have any suggestions or have had similar issues? My internet provider is Xfinity, and there was supposedly recently a disturbance in the service. Thanks

what actually happens? do devices say "connected, no internet", do they not connect to the wifi at all, does it not broadcast? 

Do you have a screen snip of the cable connections page and event logs?
