Hi,

I have been running for several years without issue a Mesh using 3x Deco M5 - all in AP mode including the 'master' (Main) unit as I have an existing router.

I purchased an additional Deco M5 to add as an additional AP point.

The App cannot find the unit (while light flashes blue) but then after finding it on bluetooth, it says to move it closer to the main unit.

Reboot main unit, 'new' M5 (v3) placed 2 feet away and still not found.

I connected it via ethernet backhaul and the main unit sees it as an unknown peripheral.

I also connected wirelessly to the new unit (192.168.68.1) which said run the app!

A bit lost now....

Any ideas?

I vaguely remember that on the V1 units you had to add additional APs while the main unit was in router mode, but thought that was fixed in later updates.

Thanks"
