Afternoon All,

really simple one i hope, i have one pair of AV600 plugs (both identical) so one plugged in with an ethernet cable to the sky hub and the other plugged in behind the tv ethernet from it to the tv via ethernet cable. I want to use another tv upstairs but the wifi is poor, can i simply add another av600 plug upstairs meaning 3 units. 

I cant see that you can buy one on its own so i believe no is the answer which worries my its not as simple as just buying more?

side question, the unit which is connected to the sky hub is plugged into to a multitab plug tower would this affect performance rather than being plugged directly into the wall (same the other end feeding teh tv)

thanks in advance
