    You can share your internet using several methods. Search for them, there is lots of good info. The best methods for you are probably a router, or 802.11b.
    802.11 is wireless, router is wired.
    The other ways are a hub or switch.

    I agree, I use a cable modem with a router and I am sharing files printers and a single internet connection to 4 computers.

    Should work fine, the only problem is if you are connected and can't surf or have other issues, the cable company may not support you. You may have to call the Router company so find one that has Voice tech support and not email only.
    They work great, just most ISP's don't support you, once you connect more then one computer.

    The ISP most likley will not support the other computers but that does not mean that you cannot surf on all computer at the same time, with DHCP enabled on the router it will assign IP"S to each workstation.

    Didn't say it would not, it will work fine, however, if you run into problems, most ISP's will not help you until you bypass the router.
    That was the only point I was trying to make. I've done tech support for 3 different cable and dsl ISP's and I hate when a customer calls and can't surf and is using a router, if they don't know what they are doing. It will work, you just may be told that it is not supported, no surprises eh?

    With some ISPs, its against your TOS to share internet access, so before you call tech support, unplug the router and dont say any thing about it :rolleyes:

    Del you are 100 % correct. Sparkey all you have to do is hook it up and let it rip. You will never go back to anything else.

    Exactly, most ISP's will support one computer connected to one modem. As a first line tiech, I hated saying 'Not Supported', but didn't want to get fired either.
    Have a great one.

    I just activated my cable modem yesterday(doing a happy dance now!!)
    I asked comcast point blank about their policy regarding routers. They are supporting the Microsoft router now. But that's the only one. I had purchased a Belkin. Once the modem was activated on the main computer, I had no problem whatsoever moving it to the router. Sharing it with 3 computers right now, soon to be 4. And I gots to say that I'll NEVER go back to dial-up! This speed is great.

    From what I gather about cable ISPs, they are not going to support people with home networks (i.e. figure out how to get the Internet to son and grandpa and office, etc), and I don't blame them.

    Their goal is to get you a working cable modem and then one IP address after that. They don't care if that IP address is a computer or a router. They simply want one MAC address to assign their IP address to. What you do after that is up to you. You can get more IP addresses from them at a cost of course.

    I have a PC next to the cable modem and router. If the question ever comes up about the router, I just unplug from the router, plug into the PC next to the modem, and do an IPCONFIG to release and renew.

    Shazam, I'm configured like a single user, and then we discuss Comcast's problems. :D

    Most of the time someone with a router calls and can't browse once we bypass the router, they can browse, but I found it they turn everything off, then turn the modem on, wait a minute, turn the router back on, wait a few seconds, then turn the computers back on, and it usually works.

    It is interesting that I have to reboot my router every week or two, it will just be disconnected for no apparent reason. I have a friend that has the same experience with a different router. Your advice is good, power cycle the modem, the router, and then reboot the PC, 90% of the connectivity issues will be solved. :)
