Hello

I have 6 (six) Deco P9 V1/V2 devices connected with wi-fi/plc in AP mode working flawlessly for two years.

I've bought 2 (two) more Deco P9 V2 to add additional coverage for the places with bad wi-fi signal.

But when I add 1 (one) more Deco P9 to the existing network of 6 (six) Deco P9 - one (random) already connected Deco P9 disconnects (red led on device is lit)

It doesn't matter if add it with PLC backhaul or Ethernet. If 7th Deco P9 connects to the existing Deco network with 6 devices one of the already connected Deco devices disconnects.

I'm using latest available firmwares:

Deco P9(EU)_V2_1.1.3_201228

Deco P9(EU)_V1_1.1.3_201228

Main unit is V2 revision device.

Currently I've created additional standalone Wi-Fi network with these two new Deco P9 devices, but it is not so convenient as with unified mesh network.

How to add more than 6 (six) Deco P9 to one mesh network?

Can you provide me with new firmware to fix this issue?

Thanks.
