Trying powerline adapaters as a solution to my sister's WiFi complaints. Tested it out between the two outlets I am going to work with, got ~96 mbps. Not that great on the face of it, but this is a pretty rough solution. Should be enough for an AP though. Funny I got the adapters before the long ethernet cable I need though, hah.
Coax was an option but there's stationary furniture (not my idea) blocking the ports.
