Hello :)

A Fritzbox 7530 AX is in use and this establishes the Internet connection. This runs without problems.

In another room is the TP-Link Archer C80. This is in WDS mode and establishes the connection to the Fritzbox. A PC is connected to the TP-Link via LAN.

Problem:
The TP-Link loses the WDS connection to the Fritzbox. A restart is not enough to restore this, but I have to rename the SSID of the Fritzbox and rename it back to the old one; only then does the TP-Link find the WiFi signal again.
In the TP-Link in the WDS settings, the WiFi signal simply disappeared. Other devices remain normally connected to the Fritzbox (smartphones, TV, notebooks).

This applies to 2.4 Ghz and 5 Ghz in WDS mode.

Does anyone have any advice on what the problem with the TP-Link could be? Firmware is up to date. DHCP disabled.

thanks :)
