I have 2 smart ceiling lamps (Calex) that connect via Wi-Fi.

On my previous network set-up (pre-Omada), both of them connected without issues.

On my current set-up with Omada (with EAP 610 and where I have no issues at all with all other clients), from these 2 smart lamps, only 1 of them is connecting, and the other one is never able to properly connect (I can see it as "client" of the EAP in the controller web interface, but without IP address assigned).

When I try to re-bind the smart lamps, every time is the same: Only the same one connects, the other one fails.

When checking the logs in the Omada Controller, I can only see this:

[Failed]Attic Smart Lamp Right (Calex) failed to connected to Attic EAP with SSID "ABC" on channel 6 because WPA Authentication times out/failed.(1 time in a minute)

I can see this log entry several times, however, this log does not happen every time I try to re-bind the lamp, dunno because it just happened before recently or because this is not related at all to the issue at hand when I try to reconnect the smart lamp.

Certainly the WPA credentials of the wifi network are correct (it is the same as my old system, where the lamp was working, and the other smart lamp connects correctly (I enter the credentials only 1 for the discovery of all smart lamps).

1) Assuming the issue is related: How do I fix it? Why is it timing out and not connecting properly?

2) Else, any hint what the problem could be?

Thanks to everyone in any case!
