Hello,

I had a network with three Decos M4 (bought in box as 3-pack). It's M4(EU) Ver:4.0, FW: 1.1.2 Build 20231227 Rel. 84005 (for Deco app It's latest).

Everything worked fine for months.

After a while, I bought another Deco M4 and I connected it to the network. But something happened. Static devices (dishwasher, Chromecasts, printer ...) sometimes used Deco, which was not closest and with worse signal. And I totally lost option for selecting preffered Deco to connect in device detail page.

I tried change the main Deco to the new one, It worked only for a short time period, then again preffered Deco option disappear. Maybe after firmware update? I don't know.

I figured out that the problem is maybe with incompatibilty between M4(EU) and M4R(EU) version. Newer Deco that I bought after a while is a M4R(EU) - Ver.2.0, FW: 1.6.2 Build 20240308 Rel. 55841. For me It's still Deco M4, but for Deco system probably not. Firmware versions for both types are different, but all are the latest.

When I disconnect M4R from the network and Deco app, everything works again and I can see preffered Deco options etc. and I think network is more stable.

Can you please check this for me?
