I would like to add a Fritz!600 WLAN repeater to the RUT240. Unfortunately, I cannot establish a connection (on the Fritz side, the entire configuration was carried out according to the instructions and the wizard, but in the end the repeater does not appear in the IP list of devices connected to the router, and the Fritz!600 signals "bad WLAN connection"). Who has already succeeded? Who knows what the problem is, how to configure it? (MAC filter on the router is disabled) Instruction Fritz! https://avm.de/service/fritzwlan/fritzrepeater-600/wissensdatenbank/publication/show/3487_FRITZ-Repeater-mit-Router-eines-anderen-Herstellers-verbinden#zd
