Cable Query

    Hi lads,

    At the moment I have a pc hooked up to a router, working no prob etc. Problem is that the cable is a bit short, so went onto Komplett and ordered a Patch Cable Cat 5e... however this one doesn't work, in that the connection occurs saying 100mbs network but no transfer occurs.

    Is it possible the cable is faulty even though a connection is clocked? Or is there a difference between how the different Cat type cables work? I'm not 100% on what the other cable is that works


    Any help is appreciated

    You need a RJ-45 crossover cable.

    So the Cat5e cable is useless when used with a wireless router? Can I get an adapter to use with it?!?

    Am probably coming across as stupid now but have to ask, the cable has been pushed through several walls to get to the comp already!!! (not by me though!)

    Where it says 100Mb/s thats just the max speed your network card on your PC supports. Cat 5e is what you want ( RJ 45 is just the name for the hard plastic bits on each end of the wire that you put into the socket) .

    You more then likely got a crossover cable, which is used for connecting 2 PC's and not a PC to a router . You just need a standard Cat 5 e cable , not a crossover cat 5 e.

    For a PC-Router connection you should be using a straight through cable not a cross over. Cross over would be used to connect a router to a router for example. Although in most modern equipment it doesn't matter as the interfaces will do the crossover themselves if they need to.

    Yep it's a technology called Auto MDIX. Enterprise equipment definitely does it and I'm pretty sure it's standard in most network kit now.

    Because not all equipment does Auto MDIX and it's useful to know how to wire up cables if you plan on working with networks.

    Are you on adsl or wireless BB ..if its wireless and your router is the mains powered black box thing that they all seem to use.. You do need a cross over cable..:)
