Model: Deco X1500  
Hardware Version: V1
Firmware Version: 1.1.7

I have 3 decos xe75 work great. I have Iot network turned ON. I added deco x1500 and no devices want to connect to it ?
What could be the problem?
I also swap location with other deco xe75. On new location deco Xe75 all devices connected immediately and on X1500 no devices connect.
Only my phone connect on X1500 it can connect on 2,4 and 5 Ghz. I try to set device connection priority to x1500 but no success.
Does anybody know what would be the problem? 
Regards

  @Marko_M 
For all out there who struggles with same problem I figured out. 
My main deco XE75 have IoT network which I setup, then I added deco X1500, which does not support IoT Network
so this network was not emitted by X1500. When you enable IoT on app there is no warning that some of your deco
not have these function. You can only use main network or Guest network with X1500.
Best Regards

  @Marko_M Hi, thank you very much for the update.

Deco X10 as well as Deco X1500 added the IOT network on the latest 1.2.0/1.2.1 firmware version, while 1.1.7 hadn't yet.

So if you were still on 1.1.7, it is suggested to manually update to the latest 1.2.1 version via web UI:

Wait for your reply.

Best regards.
