I have several networks, I have included the deco models for two different networks.... each network only as 1 model of Deco - each has 3 nodes.

When I set them up they had ethernet backhaul from the primary units to the satalite units

One has no switches [direct connect] between primary and satalite, one has a switch connected to primary that also includes things like security cameras. [The modem/router from the cable company is plugged directly into the DECO port 1]

BOTH NETWORKS WERE WORKING PERFECTLY WELL UP UNTIL A MONTH OR TWO AGO.

-------then------

WIFI objects (smart switches etc) started falling off the network. if I did a reset they sometimes wouldn't even see the correct network SSIDs of the network. [2.4GHz smart home devices]

IF I remove the ethernet backhaul everything works perfectly. If I put the ethernet backhaul back on I get the same symptoms in a few hours.

Has anyone else experienced this issue? Was this caused by a firmware update?

Is it just me?

[EDIT PS] Both network are using wireless backhaul now, the satalites just used the wireless default instead of wired
