I needed to connect my router to my computer, at opposite ends of the house, with a cable since the distance was drastically slowing the WiFi connection. The £4 cable I first got worked when new but when threaded through the plasterboard from bedroom to attic space, over the joists, down through the cupboard, under the floorboards and up by the router (with much squeezing, grovelling and stretching on my part to get it through) the £4 CABLE DID NOT WORK. I then purchased this, more expensive, non-kinking cable from Belkin and used the cheap cable to 'pull' the new cable through the same route. Any difficulties were due to the cheap cable kinking, the new one slid into position without a problem. You get what you pay for and if you are going to some effort to thread the cable you are better starting off with a better cable. This Belkin Cat5e Snagless UTP Patch Cable (Black) 30m worked very well for me.
