Hi everyone.

Since a few days i have a strange problem, i am not sure if it is since the last firmware update cause i can't remember when i did the update, but it was not long ago as well.

Following setup:

ISP 5G Modem ->(wired connection) Deco X50 Main -> (wired connection) Zyxel GS1100-16v3 Unmanaged Switch -> (wired connection) Second Deco X50

Since a few days when i connect everything like this way, the second deco connects to the main deco via WLAN and every wired LAN device, like Apple TV, Sky Receiver, ..., has no internet connection as well as all WLAN devices that are connected to the second Deco X50.

If i disconnect the second Deco X50 and reboot the main, everything works perfect.

The strange thing is, that this only occurs since a few days, the last 4 months i didn't have this problem.

The second Deco was connected to the main via LAN and every device that was connected to it with WLAN or LAN worked perfect.

Anyone elxe had this issue or someone has an idea how to fix it?

Thakn you and best regards
