Can I wire a Helix WiFi pod using a CAT 5 Ethernet cable?

Can I wire a Helix WiFi pod using a CAT 5 Ethernet cable to extend range? The place where I want to put it (my garage) barely gets a signal so I'd like to run cat 5 to that location so that my car, WiFi cameras and other devices will be able to access my WiFi. I don't want to have to run a series of pods in several locations leading to the garage.
