TP-Link TL-PA4010PTKIT Powerline Adapter Kit (500Mbps, 300m, 3-pack) (optional)
Unpack, switch on, press button 1 min. wait, done. The speed is not reached, but stable 50 Mbit, absolutely sufficient for my case. The parts do not have their own IP, and enter the router addresses simply by. This is in my opinion the right way. Usu
