I have a house, which is separate from a garage, and would like to provide wi-fi into the garage. My hope was that, with the garage on a completely separate electrical circuit to the house, I might be able to use powerline adaptors between the house and garage, and run an ethernet cable between the two (using the ethernet ports on each of the WPA4220's). So effectively, the first powerline adaptor, connected to my house circuit would then provide ethernet connectivity to the other WPA4220, which will then provide wi-fi and a spare ethernet port into the garage. Is this feasible/possible please?
