I just moved house and whilst the new condo has an inbuilt cabinet with all the network cables/fibre point/etc in one tidy spot above the fridge, my master bedroom is outside the range of my main 5ghz wifi (despite the place being like 70 sqm). If I'm lucky and able to get a connection, my download speeds are in the <5Mbps range from my side of the bed (my fiance is slightly closer and she can get 10-15Mbps).
I resorted to using my second router as a second router for this network (and removing my DNS settings from there which I used for Netflix) so I can get a strong 50-100Mbps in the bedroom. But then for fun I thought I'd try hooking up my ethernet adaptor again in the master bedroom (love how it's prewired with ethernet ports in each room).
