@valdisz That is the nature of wi-fi wireless signals. The further you get away the weaker the signal and the slower the speed, also in effect is objects between the Router and the Device, this is walls, furniture etc. The only 100% guarantee is Ethernet connection, or you have to look at mesh or boosting the wi-fi, but each comes with its own problems, and as you are fully focused on speed, then i personally am not going to advise either, you need to look and make up your own mind....
