There's a small network that's in 1 building that we want to extend to another building about 75 feet away but running an Ethernet cable is not easily doable. I'd like to extend the network wirelessly but I don't recall ever going from a wired, to a wireless, then back to a wired network as in the image. I need to know what Black box A and Black box B would be if this is even possible. Is there such a thing?
Thanks,
