Your router is now both, wireless client and wireless access point:
It has both interfaces up and running.
It means that as a client, RUT955 is connected to another access point, which can be used as an internet/WAN source.
When acting as an access point, other devices (laptops/smartphones) can be connected to RUT955 by connecting to its SSID, which starts with RUT955-B.
From the configuration standpoint, interfaces section seems to be set up correctly, your LAN subnet does not overlap with the subnet of the access point you have connected your RUT955 to.
