I put in Cat5e cabling in all my bedrooms when I built an extension (and
knocked out all bar 2 of the internal walls upstairs).

I bought modular sockets (which can be RJ45/BT) from Farnells and used a
chrone tool to connect the Cat5 cable into the back. I put in two cable runs
per room - for some resiliance in case one of them getts squashed, chewed,
damanged, nailed, etc! All get routed to my main PC room which has two
double gang faceplates (with a maximum of 8 net sockets). Patch leads then
connect each room to the switch which is the router for the Internet. Cat5e
cable was from Screwfix. I think in total it was around £100 for 5 rooms
worth of stuff.

Wireless is good (well above Internet connection speed) but whether it's
fast enough depends how much copying across the LAN you do (I do backups)
and whether you are patient or not (heck, I'm not that patient!!).

This summer, when the wife is on holiday, I intend to take down the
manky lath & plaster walls and ceiling in the main bedroom and put up
plasterboard. This will enable me to run some extra cables for sockets and
a
telephone extension in the kids room so they can connect their computer in
the void.
It would be handy to run a network cable from the box room (my
office)
to the kids room to exchange data in the void, rather than trail a data
cable along the landing. Can I get a diy installation of sockets and
cabling
anywhere?

Thanks
