Question about FRITZ! FRITZ!Repeater 3000

I'm tapping in here. My Salt fibre box doesn't reach all the rooms in terms of wifi. Will the FRITZ!Repeater 3000 fit? Thank you.

I assume that Salt Fiber already has a W-Lan router. This must then be connected to the Fritz Repeater with the WPS button ... It is advisable to set up the repeater in the middle of the most important destination. 1-2 rooms or one floor can usually be connected very well.

I can't answer your first question, but I assume that the Fritz3000 will fit...
So: We have the repeater in the kitchen on an open shelf (at knee height). This 1 device covers the whole house - living area, dining, entrance (ground floor), 1st + 2nd floor. Still very good speed even on the 2nd floor. The staircase is open and it is a wooden building. i would buy the Fritz!Repeater 3000 again anytime.
P.S. If the range is limited, extending it should not be a problem. and: I configured the repeater directly on the PC, i.e. RJ45 cable out and the repeater connected and then set accordingly. It works fine. If it is configured in the home network, complications may arise. Have fun - and - bliiiib xond!
