I only get about 350kb/s at best download speed, but I have a 4mb line speed. I'm using a TP link powerline adapter to connect through wall sockets from my router. Should I not have a much faster speed? My friend who lives in the same area as me has a 10mb line speed and gets about 8mb/s which is quite good, he has a wired connection. My router is about 5 years old so I thought that that might be the problem. Does anybody know the reason for this happening?
