For anyone with speed issues, I encountered something I wanted to share. In my house, the builder had pre-wired all the rooms with CAT5e cabling and RJ-45 wall plates. They all terminate in the basement where I keep my AT&T gateway (modem/router). Since the Orbi router should be in a central location, it's sitting on my main floor connected to one of the wall plates, which leads to a switch in the basement which in turn connects to the gateway.
When I first set it up, I used the flat CAT5e cable that came with the Orbi to connect the router to the wall plate. I couldn't get anything past 95Mbps. It was driving me nuts. So I decided to change it to a Cat6 cable I had lying around and viola! My mobile devices jumped to 400Mbps. I understand connecting a Cat6 cable to existing CAT5e cabling will only produce speeds the CAT5e cable can handle since it would theoretically be the bottleneck. But my point is, the flat Ethernet cable that came in the box with the Orbi may be the root cause for folks who are having speed issues. Just wanted to share in case it helps anyone else.
