Four WLAN boxes should be technically possible. But the question is: do there really have to be so many?
If the fourth one cannot be registered, it may be that there is still a “corpse” in the basement, i.e. that another WLAN box was previously registered in the system - but this box is no longer there but still occupies the space in the system.

But describe your flat/house (how many rooms, how many floors, how many m2 area)
