I presume you want to stay with 2 accounts for splitting bills ? Or do you want to drop to 1 ? Easiest way for a rental , if you can ' t drill holes and stuff , is to use powerline adapters . You can setup a pair from the router to each floor you want , and have a wireless AP or switch powerline with ethernetYou ' ll need a wall outlet for each powerline adapter , and you can get one ' s with AC passthrough as well so you can still use the socket for other things . You can also just use a wifi extender as you do now , but that has a performance hit as the connection has to travel one more loop back and forth . <| sep |> No , he can cross just fine . He just chooses not too . <| sep |> Just look at the controls in the game options lol .
