    Changing ISPs

    Hello,

    I currently have dsl service with ISP-A, using a modem provided by
    ISP-A to connect to the Internet. I would like to try the service of
    ISP-B and was wondering if I could do that by just swapping the dsl
    modem provided by B for the dsl modem provided by A without canceling
    the service provided by A. That would enable me to test B's service
    to see how good it is. Is that possible, or do I have to cancel A's
    service first before replacing A's modem with B's modem?

    Thanks for any comments.

    Well, anything is possible. But I highly doubt the modem is the
    rate limiter. More likely settings inside the DSLAM (the "head"
    end inside the telco CO, RT or microRT) control the service.

    If you want to check, dig out the technical specifications on
    the two modems (see mfr websites) and compare speeds & services.
    If your current modem will cover the new speed, it is very
    unlikely switching would help. It might if your modem is ancient.

    Thanks, but I didn't do a good job explaining what I want to do.

    I want to switch from isp A to isp B without terminating my service
    with A. What I am wondering is can I use A's dsl modem to connect to
    isp A and switch wires to B's dsl modem to connect to B? I guess I'm
    wondering if the isp I connect to is determined by the modem I use or
    is it determined someplace outside my home?

    Thanks.

    You can only do this on a separate pair (phone line).
    AFAIK, only _one_ DSL signal can fit on a POTS line.

    OTOH, there is nothing that stops you from having two lines,
    each with separate DSL. Someplaces will even sell you DSL
    without needing phone service. You'll need a second ethercard.
    Most premises wiring in the past 40 years (quad or later)
    has been good for two lines.

    Such a setup is a cheap way to do "multi-homing", but may
    not really be unless you're connecting to a CO, and each of
    the ISPs has their own routers there. With the right routing
    software, some requests go to ISP A, others to B .

    Robert is correct, for DSL home use, one line equals one ISP.

    Consider your present DSL line a pipe. One end has your modem and the other
    end is your ISP's router.
    Any DSL modem you install at your end will still only be able to contact the
    router your ISP has your phone line set to use.

    I use Qwest as my DSL provider but no longer use their supplied modem. I
    purchased a D-Link DSL-2640b which Qwest does not actively support, as in no
    tech support. The unit works just fine once I manually configured it to
    what Qwest's router wanted to see from my end. So yes you could most likely
    use the other ISP's modem on your existing line but it will still only
    connect with your present ISP, and only if you correctly configure it to
    what your current ISP expects to see from your site.

    Only if you order another line going to the other ISP will you be able to
    connect with them directly with out killing your existing line first.
