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....
