I am confused about the speedtest that you are able to perform in the plume app. I recently setup my 3 hubs via wired backhaul and it does not appear the speedtest is accurate. Before I wired the hubs it seems the speed test was calculated to the modem. Now, I am not sure what it is calculating. When I run a speedtest from my desktop that is wired to the ISP router, I get my rated 1Gbps speed.
See the screenshot attached and you can see that even plume was calculating correctly before.. any tips are appreciated!
