      ethernet cable

      As I shall shortly be joining Sky BB could I ask a simple question concerning the most efficient length of an ethernet cable. I understand that with most cables carrying a signal, the signal strength will reduce with an increase with cable length. What would you consider to be the maximum length of cable to connect the router to the PC? Am I correct in thinking that, if it can be done, an ethernet connection is superior to a wireless connection. Many thanks.

      Unless you have a house like Buckingham Palace you will not need to worry about the length of your ethernet cable. Cat5e which is most common, has a maximum recommended length of 100 metres. Cat6 is similar except it will support gigabit speeds.

      In general ethernet cable is consistently faster than wireless and is not so susceptible to interference. I have seen claims that wireless is faster than cable, but I have never personally witnessed it.

      Just to add to that, be careful not to get ultra cheap Cat 5e cable. This is often copper coated Aluminium of multi-stranded cable. Generally Cat 5e cable currently works out to be around 50p per metre at present.

      As for laying the cable, avoid sharp bends and tacking the cable in place too tightly, as this will reduce the potential of the cable if it is a long one. Gentle bends are fine.

      Also Cat 5e and Cat 6 works perfectly well on a 1Gbit LAN. Cat 6 actually supports 10Gbit. Cat 5 works at up to 100Mb.

      Multi stranded is intended for making up patch leads, it is more resilient to being flexed, single stranded is intended for structured cabling.

      No problem.

      Since the connectors mostly sold for Ethernet cable are IDC, it makes not sense to use multi-stranded cable as these wires do not make good connections normally in IDC connectors. Even if the cable has already been made up, it is quite easy to break the clip and normally it is very easy to replace the connector.
