Wifi Boosters

So my wifi boosters are appearing in the My Telus Wifi app and according to the app getting excellent signal (they're all hardwired with ethernet) but when I dig down into them, no devices are showing as connected to any of the 4 boosters I have. These were just recently hooked up by a Telus Technician, I've tried restarting them, but nothing. Wifi seems to be mostly working (fastest strength by modem in garage) but by the time I'm on my second floor bedroom (which has a booster in it) my signal strength drops off a lot so I believe i'm just connecting to the modem only. Any ideas on how to fix this problem?
