We have both wired and wifi networks in our house. We want to provide wifi to a workshop in a back garage. The wifi signal is pretty good outside at that point, but inside the garage it doesn't work very well. That wall is pretty metal-laden, so I don't think just a repeater through it would work, at least not very well.
I have a general idea that I might be able to hang an outdoor wifi device that could tie into the home wifi network, and then connect through a wired network into the garage/workshop, where I would have another wifi device that would broadcast a different wifi signal. But I don't know what the devices that I would need are called (bridge, client, access point, router?), or if this even possible (can you have a second wifi network within a larger network that was already wirelessly "bridged" (not sure if I'm using "bridged" in the formal way it is defined in networking terminology))?
I've done quite a bit of research, but see contradictory information. Any info is appreciated.
