Just installed this AX11000 this weekend in AP mode. Had an issue with network this morning. When I went to log into the admin panel, browser wouldn't connect. Port scan of the device showed it was only listening on ports 22 and 53. Power cycled it and the network issue cleared up. Now when I port scan it, I can see Ports 22, 53, 80, and 443. Later the same day try to log back in and browser won't connect. Port scan again shows only 22 and 53. The Tether app can still connect and appears to be working correctly.

It appears the web server providing the admin UI is crashing.
