Archer C9 v.4 lost 5Ghz network.
I've had few router resets over the last month. The router would randomly reset itself. Now, my 5Ghz network is missing from the SSID list on my wireless devices. I checked TPLINK setup and the 5Ghz radio is turned off. When I try to turn it back on, it says it is saved but the network button turns back off and the 5Ghz network name is blanked out. I seemed to have lost my 5Ghz radio??
