Listen I’m not huge on networking knowledge I just need some advice. On spectrums 300 mbps plan. 3 story house, bottom level is just a small basement for storage and garage. Bought a 3 pack deco m4, main node connected on the main story to the modem and puts out around 320-350 down speed. The other 2 nodes are top floor, one in a bedroom and the other in my office. The one in the bedroom hits around 140-150 down, and the one in my office was hitting around when connected wireless 80, so I connected it with a powerline adapter to the main node and now it’s around 110-120 down. I just feel like the strength they put out is pretty weak and want some advice if I just need a stronger system. I was looking at the deco xe75 since it seems to have a stronger range. Also picking up some cat6 cables later to upgrade some 5e cables I’m using currently.
