does it make sense to use a wifi repeater? if so, which one? i keep losing wifi connection in the flat, as office and router are located in sep. rooms/behind door
It can make sense. Especially if there is a long distance between the access point and the end device. It is important that the repeater is in a place where reception is still good. Alternatively, Powerline (e.g. devolo) could also be a solution.
