Hi, I have 4 Deco X10 in total.

One I bought in Denmark (EU) and one I bought in India(US)

The US-version just got upgraded to firmware version  1.2.0 Build 20250306 Rel. 40376 , where as the remaining three are on firmware version 1.1.7 Build 20240911 Rel. 53484

In the new version (1.2.0) which is the MAIN, IoT network has been introduced.

But the three others can't handle this, making the IoT network very limited in range, as it can only be broadcast from the MAIN unit.

Does anyone know what to do?

I would prefer to download the  1.1.7 Build 20240911 Rel. 53484 version an manually install on my other Decos, but I can't find that version from the TP-Link download section.

Please help
