    Motorola SB5100 cable modem - is it really dead?

    I have been using this cable modem for about a year now. We lost our
    Internet access last Friday. This is our own modem (not rented from
    Comcast).

    There is a light at the front of the device labeled "Online" which is
    currently staying off. According to the manual, that means "IP
    registration is unsuccessful."

    Called Comcast twice (different reps) and both the times they said
    that they are not able to access (see) the modem and that the device
    has failed. My options are either to buy a new modem or rent one from
    them at $3 per month.

    Power, Receive, and Send lights are on. Is there any way to ensure
    that the modem has really failed (without relying on what Comcast
    people are saying)?

    Thank you very much for your time.

    This is why I lease modems. Either way, it's their friggin problem.
    No fingerpointing.

    If online doesn't light, there's something keeping it from talking
    with the head end. The ultimate reason may or may not be the modem.
    If you own your modem, you'd be rolling the dice to have them come out
    onsite and check the connection. If the issue ends up being your
    modem, then you're out a truck roll charge. If it is their
    connection, there's no charge, but you're out some heartache.

    That $3 lease fee starts looking pretty insignificant before long.
    Think of it as "enhanced service and peace of mind fee so if ****
    don't work, their truck is coming to your house to find out why.

    That said, if you have a neighbor with the same service, ask to
    borrow their cable modem for 15 minutes. That should tell you if it's
    wiring of the modem.

    Leave it unplugged for a while if you havent, or hit and hold reset fro liek 30 secs and see if it connects, if not you'll probably have to have them come out.

    When you say they are on - are they always on solid or flashing? Do
    any of the other lights flash in any manner. I suppose Comcast had
    you remove power from the SB5100 for some period of time and then
    power it up again? Visually, did anything change?

    Do you know how, and have you logged into the SB5100, from your
    computer, to see its diagnostics and logs? Is a small TV available and
    can you try disconnecting the cable from the SB5100 and connecting to
    the TV?

    Please let us know.

    Best wishes to you.

    Incidentally, are you aware that Comcast is dropping Usenet
    service as of October 25?

    That modem comes with a two-year warranty, so if it has failed
    contact Motorola for repair or replacement.

    It uses the 192.168.100.1 IP address that is (more-or-less)
    standard for cable modems.

    Re: Motorola SB5100 cable modem - is it really dead?

    I rented a cable modem from Comcast store. According to the lady at
    the desk, all was already setup and I just had to replace my existing
    modem with this rented one. I took it home, and replaced my current
    modem. Still the same issue - no Internet access.

    I called their support. This time, they did some elaborate tests,
    pushed some files/data to the modem and eventually made it work. Now
    we have Internet access via cable modem. However, my wireless router
    isn't working now. I guess I'll have to change some settings (to
    accommodate for the new modem).

    I am still not sure if the old modem had really gone bad. I completely
    agree with Todd H.'s approach and stick with Comcast's modem. I have a
    free cable modem to give away for someone in Houston area with spare
    time.

    Thank you all for the time you have taken trying to resolve the modem
    problem.
