Thanks for your help! The problem is solved and it was very trivial. My router is defective, I replaced it and now everything is working again
I found a few different article that could help you with the setup of wifi, please see below.

My Xerox B210 worked fine until today, I could print via Wifi and USB from my Macbook Air M1. But now I can only print via USB. I can't access the printer via wifi at all, not even when I try to reach the setup-page at localhost. I'm not sure, because I don't print a lot, but this could be related to an update of my Mac to MacOs Sonoma. Or could it be that my Wifi router also updated, and uses now WPA mode (CCMP)?
Wifi direct is enabled on the B210, so is Air Print. But "Wireless Setup" is "Disabled with no connectivity" according to the setup-page of tbe B210 (which I can see, when I connect via USB, but it load terribly slow, which it normaly didn't).
