I bought the RT-AC66U off of ebay. The first thing I did was upgrade it to the latest Merlin & factory reset it so I have no knowledge on the router's prior abilities.
The router restarts on its own every 10 minutes... I thought maybe there was a bug in the firmware so I tried to downgrade it to the latest ASUS firmware and cannot. I see the upload progress bar showing that it is applying settings, etc... and then suddenly it'll go back to the login screen with Merlin still installed.
Overall I'm confused where to even begin with troubleshooting if it's hardware, etc. What logs or steps would be the starting point?
