    I have a dell desktop working off cable and just got a dell laptop. I
    ordered a Linksys router (not yet arrived) and have a very basic
    question or two.

    Is this the final lineup after configuration?: internet cable goes into
    modem; modem cable goes into the router; and the router feeds the signal
    to both the desktop and the laptop. If so, will the surfing speed of
    either be compromised?

    If the desktop would be slowed down by this arrangement, can the
    components be lined up in such a way that the desktop remains wired to
    the modem?

  2. internet cable -> cable modem
    cable modem -> router 'wan' port (wide area network)
    router lan port -> desktop (local area connection, hard wired to pc just as
    router wireless lan signal -> wireless laptop

    your cable modem likely operates between 3-6mbps. the router can process
    data at a much higher rate so internet performance will not be compromised.
    but of course if you share your internet connection then that means it is
    shared... to the total bandwith of your internet connection will be devided
    among the demands of the two computers at any given time. your latop if
    connected wirelessly is also subject to the quality of its connection which
    can vary based on signal strength (distance from router or interferance).
    wireless 'b' connections at full strength can go up to 11mbps and wireless
    'g' at 54mbps - so either could provide more bandwidth than your internet
    connection can deliver.

    in *important* thing to note is this: most cable modems bind to the direct
    network device that they 'see' after they are powered on. so be certain to
    power off then on the cable modem after you connect it to your new network
    router. and if you remove the router from your network and connect the
    cable modem back to the pc be sure to power it off then on or it won't work
    if connected directly to the pc until you do.

  3. direct should read 'first'

    Many thanks for a clear explanation.

  5. kind of you say despite all of my typo's. i would like to add... you do
    not need to install your cable company provided software on your new laptop
    (or any pc for that matter). such software is unnecessary and in my opinion
    does more harm than good. they want you to install it so that they can
    remotely control your pc to assist with troubleshooting it. the only real
    advantage to you would be that it configures your email reader which you can
    also do manually. the new router will be plug and play, nothing to
    configure, as long as you remember to power off/on the modem after you
    connect it to the router. you may want to configure the router to add
    security to the wireless component. this would both prevent strangers from
    using your wireless internet connection without your permission (and
    steeling your bandwidth) as well as protect your wireless information from
    being seen by others in close proximity.

    Just to make sure you understood Christopher's statement that, "the total
    bandwith of your internet connection will be divided
    among the demands of the two computers at any given time," bear in mind that
    most of the time your two computers will not be sending or receiving packets
    at the same time. That's implicit in his statement, but not everyone
    appreciates what that really means.

    For example, say that while you're reading a webpage sent back to the
    browser on one computer, you click on a link in the other computer's
    browser. It will send/receive at the full 3-6 mbps bandwidth. The
    bandwidth is only being used when one computer or the other is actively
    sending or receiving packets. If you're alternating clicks between the
    computers, you won't notice any speed degradation. It's only when both
    computers are trying to send or receive at the same time that you'll notice
    a slowdown.

    The bottom line is that it's unlikely you'll notice any speed difference
    under normal web browsing activity. However, if you're using both computers
    and one or both are doing long file downloads or uploads (e.g., peer-to-peer
    music/video sharing), then you'll notice the effects of bandwidth sharing.

  7. Basically, that is correct. Let's correct it a bit:

    -Cable TV line goes into cable modem
    -Ethernet line from cable modem goes to WAN input on Router
    -Desktop connects to wired port on router
    -Laptop connects either to another wired port on router, or via wireless
    LAN (you didn't say if it was a wireless router)

    That's the way to do it, it won't slow down either computer at all (most
    of the time) or significantly (the relatively small "rest of the time").
