Hey there, I recently got myself a powerline adapter from TPlink. I got it because I cannot get an ethernet cable upstairs to my room, so I upgraded from my wifi adapter (That I thought was the reason why my ping numbers were bad) But I seem to get the same problem. Noone in my house downloads anything, just another pc downstairs mostly on Idle and a few mobile phones. I have a Virgin Media super hub with I think 100mb. If anyone could possibly give me some pointers into fixing this I'd be very grateful!
