It appears that a Boost device will only connect to another Boost device which is connected by an ethernet cable to the modem.
I have a fiber optic connection with a T3200M modem and 4 Boost devices. I am not getting errors but the Telus App shows a very weak signal on 2 of the devices (-71 to -75 db). As a test, I moved one of the devices (Boost A) half way between the Boost connected to the modem and another device (Boost B) with a weak signal. I started Boost A and it showed excellent signal strength. I restarted Boost B but it still showed the same weak signal strength. Without moving Boost A, I ran a temporary ethernet cable to Boost A and restarted it. I now had 2 Boost devices connected by ethernet, the original and Boost A which is closer to Boost B. I restarted Boost B and it now showed excellent signal strength so it appears it connected to Boost A but wouldn't connect before I connected Boost A with an ethernet cable. Can anyone verify if this is true?
Is there any way, using the Telus App or anything else, to determine which Boost device another Boost device is connected to?
My understanding is Boost signals are grabbed from the wired home unit, as that acts as the controller. You might be able to finesse the configuration a bit more on the web utility: http://teluswifi.home/login.htm
