Deco X50 mesh (1+2 satellites wifi connected) works extremely well when on the router mode. 

As X50 doesn't have SQM, I decided to go for Ubiquity Edgerouter 4 to get more stable throughput.

For that reason, I hooked up the Edgerouter to the modem and turned X50 to AP mode.

1. After rebooting all units (modem, router, x50's), main X50 shows solid red

2. All satellites show solid red

3. Deco app cannot connect to the X50

4. Even if on red, X50 still provides the wired network on satellites

Edgerouter DHCP works and gives the ipv4 port to the computer hooked up to it.

There is nothing blocking the traffic

What might be going south with this
