Hi there all I have a puzzle that i hope someone can help with . I set up a TP-Link DR900 Modem/router on my B.T Infinity 2 which was straight forward and easy , i set it up using my laptop via an ethernet lead and i use it on wifi normally , i did a speed test and i got 64meg and 19 meg .Upstairs i have my p.c unit which is connected via an ethernet cable and powerlines T.P -Link , but when i do a speedtest i only get 30meg and 15meg .I installed the HH5 again and i get 61meg and 19meg on my p.c . why would i get these different speeds ? Any ideas ?
