Using one line from cable company for two computers

Hello,
Can I just buy a splitter for the ethernet cable for two computers or do I have to buy a 5 port switch

  1. You can also start out with Internet Connection Sharing ("ICS"):

    http://windows.microsoft.com/en-US/windows-vista/Using-ICS-Internet-Connection-Sharing


    But, the computer that is connected directly to the cable modem
    needs to remain ON, in order for the second computer to access
    the Internet via the first computer's ICS feature.

    ICS will eliminate the need for a router, because the
    ICS host will do the "routing".

    Note that you'll still need a hub or switch (see diagram at link above);
    and the host computer needs 2 LAN ports:
    one to connect to the cable modem,
    and the other to connect to the switch or hub.

    If you have only 2 computers, I believe you can
    eliminate the hub / switch, and wire the second computer
    into the second LAN port on the host computer.

    But, it's been a long time since I used ICS, so
    please confirm this latter point yourself.


    I do recall needing to revert to fixed IPs on
    both computers, in order to stabilize ICS.

  2. p.s. A good solution for a SOHO LAN is this:

    cable modem connects to a router
    which also supports a few 10/100 RJ-45 ports

    router connects to a Gigabit switch
    using one of the router's 10/100 RJ-45 ports

    each computer connects to the Gigabit switch,
    ideally via Gigabit LAN ports (Intel's LAN cards
    are terrific for this application).

    In this fashion, intra-LAN file transfers occur
    rapidly -- using the Gigabit switch and ports.

    Internet access is handled by the modem & router
    which doesn't need to support Gigabit ports
    due to the slower speed of the Internet connection.

    Even if the Internet connection runs at 50 MHz,
    a 10/100 router port has plenty of bandwidth.
