make sure you have filters on all you sockets that have someting pluged in I had slow sky connection reported it to sky they checked the system and told me to unscrew the bt wall socket and plug the router into the test socket behind the cover that knocks all the house sockets out and it ran at 4mb which is my line speed. I had my sky box pluged into the wall socket with no filter. so when I disconnected all phones and boxes moved my router back upstairs it runs at 2mb which the other 2mb is from the poor house phone wiring which is going to be my next project !!!! hope this helps Graeme
