Use Internet without WiFi?

Discussion in 'Network Routers' started by Robert Crandal, Aug 31, 2014.

  1. I want to avoid using wireless Internet. I currently use
    the Internet with an Ethernet line plugged into my
    cable provider's "black box". The only problem with this
    is that I can only plug this Ethernet connection into one PC
    at a time.

    Is there some sort of Internet splitter device that will allow
    me to divide my Internet connection to multiple PCs?
    I basically want to share my Internet with 4 computers using
    Ethernet wires only. No wireless.

    I'd appreciate any tips. Thank you!

  2. Per Robert Crandal:
    One approach would be to plug the black box into something called a
    "Switch" (which is different from a splitter).

    Google "Ethernet Switch".

    A switch almost certainly won't work in this case. If the "black box" is a
    cable modem or DSL modem, it's almost certain that the ISP allows only the
    first connected CPE device to request an IP address, so if he uses a switch
    only one of the 4 computers will get a usable IP address. The others will
    get APIPA addresses (169.254.x.x/16), so they'll be able to talk to each
    other but they won't be able to access the Internet.

    To the OP:
    The answer is to connect a NAT router, which almost always comes with a
    small switch built in. The router gets assigned the single IP address
    allowed by the ISP, but then the router in turn is able to hand out up to
    253 IP addresses to local devices.

    Connection details: the router will have a single WAN port which connects to
    the "black box". The router will probably also have about 4 LAN ports which
    get connected to the various computers.
    Note that almost all NAT routers currently on the market include wireless
    capabilities, so be sure to turn that off if it's not needed.

  4. Yes, my cable black box is a cable modem or DSL modem.

    Do you know if the NetGear GS108 switch qualifies as a NAT router?
    The specs say:

    "The NetGear GS108 Ethernet desktop switch allows up to
    8 network devices to simultaneously access the Internet."

    If not, I might just settle for a wireless router and turn off the wireless
    ability if it allows me to do so.

    Get a router.

    Nowadays, and probably for well over a decade or two, a router includes
    a switch (mentioned by Cresswell) but also includes a simply firewall,
    port routing, QoS (quality of service settings), etc. You'll pay almost
    as much for a switch as you do for a router. Do NOT get an Ethernet

    Lots of them available at the stores, including wired ones (easier to
    configure than wireless, safer, but you have to run the cables). x 10/100Mbps&Order=PRICE

    You already have your ISP's cable modem (the "black box"). Since it has
    only one input port, it's not a combo unit (router+modem). So add a
    router before the cable modem.

    No, it is only a switch and won't work for you by itself. You can use it,
    but only if you still add a router between your switch and your modem. Since
    most routers come with a switch built in, there's no need to use your GS108
    unless you need more Ethernet ports than your new router offers.
    Unfortunate use of marketing terms there.
    Routers are mostly commodity items these days, so grab something from
    Walmart (for example) and use their liberal return policy if you don't like

    If you online order from Walmart, be sure to check the box that
    restricts the sources to just Walmart. They also show items from other
    sellers. If you want or need to return an item, you'd have to deal
    with, say, Wayfair for shipping back the return at your expense if you
    bought it from Wayfair through Walmart's site. You want to deal with
    Walmart for the return so make sure Walmart is the seller.

    You don't find much "good" stuff on their electronics shelves in their
    retail stores so you'll probably have to order it online. Just be sure
    you're ordering from Walmart, not from some other seller selling through
    Walmart's site. When you do a search, select the checkbox under the
    Retailer section to pick "".
