XR500 Router keeps resetting connection

Hi there,

My router keeps auto-resetting on its own and I can't figure out why. It tends to happen at least 5 times a day, but this morning it has already resetted about 10 times. When I lose connection I have verified my internet signal on my modem is perfectly fine and am confident my loss in connection is my router. I did a factory hard reset and still the same issue. Any advice will be greatly appreciated. Thank you!
