Hello,

I have the following Setup:

Firmware Deco X50 - 1.1.0 Build 20230522 Rel. 68968

ESP32

In the DECO log is the reported for MAC: 48:31:B7:3D:CD:34 trying to disassociate, but it is not associated

When I disconnect the ESP32 device for a few hours, it can reconnect without any issues and after a while it has the same problem again.

The WLAN connection on the ESP32 is not bad and I would expect it to be able to reconnect when it is disconnected for whatever reason, but it looks like there is some sort of lock on the Deco that doesn't allow the MAC address to create an association for a certain period of time.

Maybe it counts the number of reconnects and when a threshold is reached it is blocked for whatever time, it looks like within 15min

Can anyone confirm this behavior of the DECO or is it a BUG in the firmware?

Thx and kind regards,

Stefan
