Hello, I just got a new Deco M9 Plus 3-pack, and am trying to troubleshoot slow wifi connections. I have gigabit internet speeds from Comcast Xfinity, but am only getting 200-250Mbps speeds if I am a few feet away from each note, and closer to 100Mbps if I am 10' away. I live in a 1200 sq foot tri-story house, so I was wondering if having three nodes in such a small area (compared to the advertise 6,500 sq ft coverage) could be causing problems. I get 350Mbps speeds at the main node, and 650Mbps when I connect through ethernet. After seeing reviews from people getting 700-800Mbps speeds from this model, I'm extremely disappointed.
