I am currently using the Netgear router that sky provided but I get rubbish signal and cant use it anywhere in my house apart from the room its in and the one above. I also have a Belkin N wireless router and want to use this to bounce the Sky signal around my house. I currently have my Sky Router Password but I have no idea what to do next.

Im not particularly computer literate so step by step would be great.

Thanks in advance
