Orbi 960 slow & intermittent connection

Hello,

I have been using an Orbi 960 system running V7.2.6.31_5.0.24 with accompanying RBSE 960 satellites for a year now. When I first purchased the system, I noticed a number of devices were having connection issues. Since we were moving to a new home and many of the devices weren’t previously used, I figured perhaps they were having device-specific issues (ie Nest cameras showing offline). However, I’ve since determined that the common denominator here appears to be the mesh system.

Most of my devices experience extremely slow speeds if I put a bit of distance and a wall or two between myself and the router. This despite nearly all of them showing I have a strong WiFi connection.

My set up consists of a router on the main level where my cable modem (an Xfinity Gateway in bridge mode) is located, a satellite in the basement, and a satellite on the top floor. Despite my home being 5000 sq ft with each having at least 30 feet of space plus floors/walls between them, I still experience areas where the connection is extremely slow and even some dead zones.

I’ve done all sorts of troubleshooting, from changing the transmit power in fear of overlaps, to outright removing all satellites, leaving only the router to handle all connected devices. Even when I’ve removed all satellites, I am still able to pull a strong connection in areas further from the router on the main floor, however, my speeds are extremely slow to the point where I may as well not even have WiFi.

I’m kind of at a loss here and am close to just taking a loss on this system. I’d appreciate any assistance.
