I stepped thru the setup again very carefully, and thought that this time it was all working good, however about 18 hours later I lost internet through the Smart Mesh AP. WiFi scanner showed the Smart Mesh AP was still sending out a good signal, but the smart modem could not see the smart mesh, even though the Smart Mesh still had the Blue LED lit up.

 

When I set it up the connection status page on the smart modem shows as "Good Connection" not excellent as per yours. I did notice that the connection between the smart modem and the mesh sometimes shows as 5G, and sometimes 2.4G, with signal strength at the smart mesh varying around -55dBm to - 60dBm.

 

the Smart modem is on the floor almost directly above the Smart Mesh, no more than 5 meters seperates the 2 modems, using a wifi connection between the units.

 

Using a Wifi scanner, shows no other nearby wifi aps on the same channel as either the smart modem or the Mesh on either 2.4 or 5G bands.

 

Im afraid that this Smart Mesh seems pretty Dumb!

 

 

 

Likely be interference on the 5ghz channel that it's trying to avoid. 

i tested these very heavily and never had it do this, Except in the case that it's actually a bad signal.

Example being my mesh unit in Garage. It's a -55dB 2.4ghz signal, but a -75~80dB signal on 5ghz. so it's doing exactly what it should and dropping to the more consistent backhaul.

still gets a solid 50~80mbit.

in my usecase, this really doesn't matter as the garage unit is literally just to give devices 5ghz in the garage - i hate using 2.4ghz on physical devices.

so when i come home and park up, i'm already on 5ghz, walk up to the house and it roams across to other mesh units.
