Wired backhaul on 2.1.2.18 magenta LED but correct device assignments

Up to now, I always used the ethernet wired backhaul with the router port on my router, which runs in AP mode. This worked very well, but hat the issue, that wireless devices on the satellite were shown as connected wired to the router. Yesterday, I took a look at the wired backhaul KB article and remembered, that when I had connected the router via the first "LAN" port to my network, the LED would stay a solid magenta, which was what make me switch the ports on my router in the first place, since the LED went out and everything else worked as well.

However, since then, the assignment of wireless devices, that are connected to the satellite, have always been shown as being connected wired to the router, instead of wirelessly to the satellite. After reading the KB article about how to wired the router correctly, I can state that now the satellite's wireless clients are noted correctly as being wirelessly connected to the satellite, but…

…now the LED of the router as turned a solid magenta again for 10 hrs straight.
