If you have a Ruckus wireless setup with a ZD, you can also consider using SmartMesh and putting an AP near the device as a mesh AP. The ethernet ports on AP's are basically bridged to the network.
In lieu of that, what Jim said. I've had absolutely terrible luck, FWIW, with consumer-grade wifi bridges, as they tend to either disconnect for no apparent reason, randomly drop, stop bridging, or fall into a crappy performance state until you reboot it.
It sounds like Ubiquity might be a good way to go, if you're not equipped to do SmartMesh.
