We have our main unit in living and a portal in bedroom and one in spare room. Went to use bedroom one a few weeks after spare room was added and it came up stating check connections. Connections were good and tight. So I tried a reset. Now it says bad format image then states its going to upload update, but ends up saying no gateway found. The box also flashes red 3 times then green once before repeating. We have bluesky. Any solutions to resetting on my own or I wonder when they added the spare room a connection came loose outside.
