Thave a general issue with setting up Easymesh with two AX55. They both can be configured as Easymesh main router but not as a Easymesh satellite, meaning one can't find the other. I have tried this again and again with various firmware versions. I have auto-update turned on on both routers. My setup is

                                   Floor1       Floor2
BridgedISPModem-->AX55_1-->AX55_2-->TV

The arrows are LAN to WAN connections. In this setup they can't find each other in Easymesh even though AX55_1 has literally AX55_2 as a client.  I also tried the
recommended connection procedure and first disconnected everything from AX55_2 and
moved it next to AX55_1 with nothing but power connected to AX55_2. 

                                   Floor1
BridgedISPmodem -> AX55_1
                                   AX55_2

Nothing. They just can't find each other. I tried reseting swapping AX55_1 and AX55_2.
Nothing works. Putting them both as Easymesh main routers works but is obviously instable.
