Hi All I have a problem with powerlines . I connected up the powerlines 1 to the B.T Hub ( port 4 ) and the other upstairs into my P.C I pushed the buttons on the side and the one near the hub doesn,t light up ,but the one upstairs does , then i tested the speed of it and my laptop which is close to the hub gets 69meg ( i,m on Infinity 2 ) but the P.C upstairs only gets 5meg ! any ides why ?
