my TP-link router denies access to WiFi after sometime. I have been using this as a range extender and a router as well. But the problem is the router after some time denies access to the network and I have to reboot the router to reconnect, I can see the network name in available WiFi options but i am not able to connect to it. I have reset the router and reinstalled the firmware as well but the problem persists; This started to happen recently before the router was working fine and this never happened, I think it might be due to some hardware failure of something.
