Again ill point in the direction of homeplug
http://www.homeplugs.co.uk/acatalog/...FSkNQgodMDJeqA ok its gonne cost a few quid but you only need a pair and it saves routing the cable.If your only going to use the internet then buy the 14mps version.Also your wired network goes wherever theres a mains socket in your home or an extention anywhere
EDIT please note the first network I built using these was nearly a year ago and it has run faultless in all that time
