So with sky going to use the ethernet port next year and my media center, tv, stereo all running on wireless n which is slow as hell I decided it was the right time to put in a cat 6 network plate and run a cable to the vdsl router which is in another room.
Turned out to be a mission from hell which took me most of the day. Our two bedroom place is on a concrete slab so had to go down the wall cavity and along the roof cavity. 
Room up in the roof is bugger all with cross members all over the place and you need to be a contortionist to move around. With the help of the missus did the pull the power wire up through the wall cavity with network cable taped to the end and vice versa at other end.
My god was so hot up in the roof, at least I know we are insulated well. Cable is now run and have a gigabit switch connected with all the items in the media center.
Has made a massive difference in streaming to everything and glad I have done it even though it was a major mission.

Made me realize how old and unfit and how fat I have got in carrying out the above.
