So I have a TP-Link WR1043ND v2 and I use it to share my android phones (Samsung Galaxy A3 2015) internet connection with usb tethering. My problem is that after a few hours of it working properly it has weird connectivity issues. I can access some websites while can't access others (for example: I can usually access Google, but can't access Quora). I have to reboot both the phone and the router for it to work again, so I don't know which's problem it is. It doesn't always take the same time for the problem to occur and I couldn't tie it to too many clients being connected. What could be the problem?
