Is a LAN necessary to use cable internet w/ laptop?

Archived from groups: alt.internet.wireless (More info?)

Do I have to have a desktop connected to the WAP or router in order to
connect my laptop to the cable internet connection in my home?
Or, can I connect a WAP or router to the cable modem then use the WiFi
card in the laptop to connect without having a desktop at all?
Sorry if this seems elementary but I've been searching the net and
forums and can't seem to find an answer.

    There's no need for a desktop if you want to connect a notebook to a
    wireless router.
    I curious: what made you think you may need one?

    No desktop required. My guess(tm) is that you were looking at a
    system that uses Microsloth ICS (Internet Connection Sharing) to
    provide the wireless router function from a desktop. A PC running ICS
    is used in place of a $30 router. This is common where the DSL modem
    is on a PCI card or uses USB, instead of the more versatile ethernet.
    I haven't seen it with cable modems, but it is possible.

    In my never humble opinion, this is a lousy way to share a connection.
    It would be better to replace the USB or PCI DSL modem with an
    ethernet DSL modem and to use an ethernet router, instead of the PC
    with ICS.

    Yes, that's sorta the way it's normally done. However, you still need
    a router with NAT (network address translation) to share the
    connection. If you just connect a WAP (wireless access point)
    directly to the cable modem, you will get exactly one wireless
    connection and no more. You need the NAT services to share the
    connection, which is why you need a router somewhere in the system.
    Therefore, you need either a wireless router box, or as I prefer,
    seperate boxes for the ethernet router, and the WAP.

    No problem. I prefer to answer the easy questions and leave the tough
    ones for others to deal with.

    I've never worked with wireless networks before and when I came home to
    visit my mother she has one set up. Hers has her wireless router
    hooked into her desktop and she and the person who set it up for her
    were under the impression it was necessary for the laptop to function
    on the wifi. Then when I was looking up wiring schematics for internet
    sharing no one shows one with just the router and the laptop; although
    there were some showing the router before the laptop and desktop.
    Thanks for the answer!

    My cable modem ISP is set up to recognize a single MAC address.
    The installing technician will want to connect one computer directly to the
    cable modem and do the configuration.
    If there's a desktop, of course that will be used. If there's a router
    already connected, it might work, since the tech will type in the IP
    address of the registration page. A laptop would certainly work just as
    well as a desktop.

    The technician might want to connect the computer directly to the modem and
    not use the router.

    If the technician installs with the router, then no particular machine will
    be required after that. The router will be registered. If you want to
    change the registered device, that is possible. You can also "clone" the
    registered device MAC address onto most routers so that they can be used on
    a cable modem that has a single PC registered on the system.

    Some cable systems don't have MAC restrictions, some do.
    Some can be "trained" to use a new MAC address, some require registration.
    The technicians seem to be cable TV techs for the most part.
