Connecting wireless box in garage

I am trying to connect a wireless box in my de-tached garage, but the signal isn’t strong enough to keep the box operating correctly. We have a Telus booster for our Wi-Fi. I know the boxes won’t run off that signal. I am unable to connect the box via Ethernet. Is there a way i can boost the signal from the t3200? Would just a non Telus Wi-Fi booster work? Would plugging a router into it help? Thanks

Consider using 2 poweline adapters to connect it with Ethernet. It will be more reliable than WiFi given the distance.
