I recently purchased a TP-LINK Archer C5 AC1200 Dual Band router, and can't get the WiFi working continuously. No matter what configuration I use, the WiFi gets dropped after 8-10 minutes. The power and signal on the router are green but am not able to see the WiFi name on any devices (including the LAN). When I restart the router it starts again, runs well for 10 mins and disappears again. 

I was trying to see in the forums and similar issues were reported but did not see a solution/I may have missed. I tried to do a firmware upgrade but the signal does last long enough to stay connected.Even the dropdown for Model Number does not appear in the window above. 

Am using ACT in Chennai and the Netgear router that I was using earlier was working fine. I just needed more devices to connect. 

Am I missing anything? Or is the router bad?
