How to connect to Webfig

RouterOS Beginner Basics
1

Hello,
I just purchased some RB260GS and CRS106.
The SwOS devices were easy to configure via web interface on IP address 192.168.88.1

To the ROS devices I cannot connect.
According to the Wiki their ether1 port should also be listening to 192.168.88.1 but neither connection with a browser nor a ping is working.
The computer is in the correct subnet of course.

I don’t know about CRS106 specifically, it might be different, but usually ether1 is configured as WAN with no management access and LAN with enabled management is on the rest of ports.
