Can I use/convert the broadband thick white cable as cat5 cable?

    Please could someone give me advice regarding my blueyonder cable modem.

    A white box has been installed in the cellar - a black cable from this
    goes out into the garden and then into the 'internet' cloud. A thick,
    white cable comes out of this box, runs through the house, up to my back
    bedroom and into the cable modem. On the white cable, as it connects to
    the cable modem are four "interconnecting connectors" which are the same
    as the final connection to the cable modem but look like they are there
    to lower or raise the signal on the cable.
    I have now realised that it would have been better to have kept the
    cable modem in the cellar, attach a switch to the cable modem and run
    cat5 through the house to the back bedroom for that computers internet
    connectino. Then I could put another cat5 up from the cellar to the
    lounge and have an internet connection there.

    My question after that long ramble is can I convert this thick white
    cable that is running through the house to cat5 (is there an adapter?)
    so I can install the cable modem next to teh white box in teh cellar,
    attach a switch in teh cellar, and use this white cable as a cat5
    connection to the pc upstairs?


    Any help appreciated

    The white cable is probably 75 ohm coax and will be unsuitable for cat5.

    You cannot use a "Switch" you need a "Router " as blueyonder accept only one
    connection to the

    You cannot use Cat5 in place of the Co-ax cable
    Cat 5 can only be used after the cable Modem the White cable is a RF cable
    which carries internet and TV signals

    to a modem ( cable modem or Set top box) where the signals are de-modulated
    and sent to the appropriate recipient
    A PC or TV

    The restriction on one MAC address connected to the cable modem on
    Blueyonder was removed months ago (at least before Oct 2004), so you can now
    use a switch or a hub rather than a router.

    You can't convert it to Cat5 however you may be able to find an old
    networking card that has a coax socket on it for running the network over
    that cable.
    It is the kind of thing most computer folk still have knocking about
    somewhere even though they'll never user it.

    Unlikely it will work unless it's a Token Ring card. Ethernet over coax
    (T-Base 2) uses 50 ohm coax not 75 ohm, which the TV coax will be. It also
    has a max. speed of 10 Mb/s not 100.

    Oops just seen my typo - that should read 10base2 not T-base-2..!!)

    All the TR I've seen does not use coax.

    Hmm, maybe I got it wrong, it's been a while. There was certainly one type
    of network that used 75 ohm coax. Ethernet is definitely 50 ohm though..!

    There was coax to certain types of terminal, but I have two different
    types of TR cable here; one is 8 way twisted pair (well, I think it's
    twisted, but the thickness of electric iron flex), and the other is
    Cat4. And all the gear to go with them!

    Assuming you have Cat5 at the computer.
    Take the second white box, and simply move it down to the cellar, removing
    cable clips as you go.
    Place second white box next to first box, and then attach cat5 cable to it.
    Job done.
    Coil loose cable out of the way.

    There are different sorts of coaxial cable, with different electrical
    characteristics. That might not work, even if you can find compatible

    Cable is cheap. Installation is what costs. It might not be too hard
    to replace the coax with Cat5, depending on how it was run through any
    walls and floors. You can use the old cable to pull new cable through a
    hole or duct.

    Thank you all for your replies

    I will transport the cable modem down to the cellar, unpick the coax
    cable, and run cat5 through the same holes back up to the bedroom.

    Must try harder with the planning next time 8/

    ISTR that ArcNet uses 75 ohm cables?
