Excuse the ignorance.. I want to move my PC etc about 5 metres to the other side of the bedroom. I have NTL bb coming through the outside wall to a "box" and a cable attaching the "box" to a ntl cable modem (apprx length 1.5 metres). The ethernet cable attaching the modem to the pc is approx 2 metres. Now, can I purchase a"ready-made" cable from say Maplin (or do I have to go to ntl) which will directly replace the first cable or is there any other means?
