How to enter the Wifi-Repeater admin panel?

Question

System administration

Worth DIR-600 WAN and Repeater are connected to it.
2 networks are available, you need to change the password from the repeater network. When connecting to both, it is displayed that the host is 192.168.0.1 and you can see the admin panel only DIR-600.
Somehow it was not possible to find its SP on the poppy of the repeater. When connecting directly to the network card, the repeater displays the ip as 169.198.... and manually assigning 192.168.0.1 and 0.2 to the connection does not work, there is no admin panel.
What to do?
It is difficult to remove it and get it .... just a reset? Can important settings be lost if you do this.
Thank you!
