WARNING: Ubee Cable Modem Died (heat related)

Discussion in 'PC Hardware' started by Skybuck Flying, Oct 24, 2014.

  1. Hello,

    I know this video doesn't proof much, I could make a new one and proof that
    it's dead.

    But for now this will have to do and you will have to take my word on it:

    ^ I will now issue an OFFICIAL WARNING straight from Skybuck Electronics







    I managed to keep my internet running and internet telephone too by:

    1. Keep old stuff.

    2. Using the old stuff when the new stuff failed.

    My conclusion is:

    The new ubee cable modem adapter is TOO SMALL, it gets TOO HOT.

    It's a heat-related FAILURE !


    The old one is a bit bigger and will hopefully last longer.

    I still have to call the ISP to inform them of this DISATER !

    And request a new cable modem adapter, plus maybe even a backup cable modem

    Cause it's the only phone I have... but I guess they might not to do that.

    Otherwise maybe I will have to buy the cheapest mobile phone with

    Just in case ! ;) However MOBILE PHONES have turned out to be HUGE SPY
    devices and PRIVACY VIOLATION devices, so I do not feel comfortable with

    I also DO NOT FEEL COMFORTABLE with walking around with such a thing. Cause
    it could kill me in marvelously unforseen ways. Not paying attention BAM and
    your gone.

    Nope that not gonna happen to me ! I am sorry, _THATS_ _JUST_ _NOT_ _GONNA_
    happen to me ! =D HAHAHAHAHAHAHAHAH LOL.

    I'll let that happen to other doofysus.

    They have a doofysys education for it ! ;) =D

    Skydoof ! ;) =D

    Ubee used to be called Ambit. They have a web site.


    The power adapters aren't necessarily made at the same production
    facilities as the cable modem. The power adapter could be straight from
    China, from the lowest bidder.

    If you Google the model number of your modem, there may be
    reports from other people of power adapter failures. On
    some products, these failures are an epidemic. That is
    the best way to spot a design or material quality problem.

  3. Hi Paul,

    Today I called my internet service provider. A man told me I could swap the
    defect power adapter at a local store for free.

    I will do/try so later today, I think it's a good idea to have a backup
    power adapter.

    I also asked them if they could send me a backup cable modem.

    The guy said they had two models available, however maybe the model numbers
    werent completely correct.

    A cisco epc 3928 (I think this one might be junk because there is a
    fan/ventilator inside of it I don't want that.)

    A ubee evw3221 or evw321 (e for europe I guess).

    So I researched the options, and said I'll call back. Then a women phoned me
    if I wanted to do a tv deal, but rejected cause digital tv receiver never
    worked and don't wanna pay extra.

    I joked they could send me a new digital receiver, maybe they not too happy
    about that joke.

    Then later I decided I wanted the ubee, so I phoned back.

    This time I got a guy on the phone... he didn't sound to happy about me
    trying to select what cable modem they would send me lol.

    Then he said the only had the cisco's left and lots of em... but ubee out of
    stock and weren't going to purchase them... to bad I like ubee, I never had
    a problem with them until the adapter died.

    Maybe in the future they will buy netgear 6300, a weird looking modem, I
    wonder if there is a fan/ventilator inside of it. It seems to stand up.. I
    don't really like the design at first glance, it seems weird.

    Anyway I thought about the reason why the power adapter could have failed
    and I think I may have figured it out.

    Not so long ago the ISP increased the internet speed. This is probably
    causing the cable modem to process more packets per second.

    I just felt the cable modem today, it seems kinda hot. This additional
    processing probably taxed the power adapter so much that it failed.

    My guess is the ubee cable modem will soon fail as well because of overheat.
    However winter is coming so it might just make it through the winter.

    For now we agreed I would call back in january or somewhere begin 2015 to
    see if there are any good new cable modems available.

    Maybe I will only call if my current cable modem fails.

    I had the right to ask for a new cable modem because my current cable modem
    does not have wifi capabilities.

    So that's why they would send me a new cable modem. So then I could have
    two, a main one and a backup.

    I already have some older cable modems lying around.. but I would need
    activation codes, maybe I have those somewhere... but they don't have phone

    That's the main thing though, I don't wanna loose phone capability.

    For now I will see how it goes.

    You can measure the power used by the cable modem,
    with a Kill-A-Watt meter. There are versions for
    Europe, with the right plug hole on the front. By using
    such a meter, you can determine the power used when
    the modem is idle versus when the modem is busy. My
    guess is, the power is close to constant (as the
    broadband interface needs to be processed no matter
    what traffic is carried on it). But your meter
    readings will tell you whether it is true or not.


    Generally, you won't find fans on things like this.
    Fans break easily, and the cheap ones can fail in
    as little as one day of operation. Instead, they
    try to make circuits which can take the heat.

    Keeping the exterior chassis cool, is about the
    best you can do for them.

  5. Why would increased processing show at the power wall socket.

    Doesn't really make too much sense to me.

    The device could have been created to draw constant power, and simply leak
    away unnecessary power.

    For example I'd guess my CPU would use max watt if it's at 80% processing
    power, yet it generates even more heat at 100% processing power.

    Without at least the voltage going further up...

    Do you believe that each % of cpu usage would translate into noticeable more
    wattage usage ?

    If so I'd like to see that proven with a youtube video ;) just to be sure ;)

    If you buy the $20 meter, you can find the answer to all
    of these questions you have, by yourself. No Youtube
    video needed.

    An example of some meters here.


    One of them uses an Analog Devices chip. This helps explain
    how the chip can make accurate measurements of power.

  8. 11:27 minutes for one lousy blown power supply? You are obsessed. You
    also make terrible videos, mumble excessively and don't know how to do
    video editing. The cursing and swearing doesn't improve what is left
    of your image.

    Take it apart and replace the blown capacitor. It's a common problem.
    This is a similar Netgear power supply:

    Replacing the obviously blown cap fixed it. It's easy, if you
    remember to unplug the power supply before soldering.

  9. *YOU* seem to think that something gets taxed more.

    Would there not be a cost?

    You sure taxed the letter w with that sentence.

    I think it is youw wee wittle bwain.

  10. Unplug it? that takes the fun out of it..

    If your electronics feels, "kinda hot", you should have no problem what
    so ever. Even commercial gear is rated for 70 C° and should not
    experience noticeable failure rates near that temperature. If it were
    over 40 C° it would be very uncomfortable to the touch and as it passes
    50 C° it would feel like it is burning your skin. But to know for sure
    you need to open the box and measure the temperature of the chip making
    the heat.

    "Kinda hot" usually means it is working well within its parameters and
    should offer long service. After all, if you don't want the temperature
    to rise some it will need a fan to get rid of the heat. By the
    temperature rising 20 or 30 C° it will cool without a fan and still live
    a long life.

    As others have pointed out, an increased data rate does not imply that
    the unit will get noticeably hotter.

    Two points... the first is that there is no reason to draw power that is
    not being used by the CPU and other parts. There is waste heat from the
    inefficiency of the power supply, but they don't draw "constant power"
    regardless of the CPU draw.

    The other is that it doesn't matter what part is drawing the power. All
    power dissipated by components in the box will make the box hotter which
    is what you are feeling when you touch it.

    Hi Skybuck.

    I know I'm responding to an old post, please overlook that. I
    recently subscribed to a few of these newsgroups and this thread came
    up. [g]
    I have checked out your video. It's much longer than is needed to
    show us a bad power supply. It's probably just killed a resistor or
    something inside of it. You could probably fix it.

    I did find the case you have to be interesting though, and not a bad
    sized monitor either. Icons all over the place too. Looks something
    like my primary setup here, but yours is much much newer.

    The swearing and lack of video editing doesn't help you though. I'm a
    but of a cuss like a sailor person myself, but I try not to do that
    in public or in videos that I'm going to give to the public.
    In the states (TN specifically in this case), using Charter, We
    actually have two entirely seperate cable modems. One is tied into
    this network to provide it internet access and the other is tied into
    the telephone lines for the house. The only one with an external
    power adapter is my cisco cable modem; that provides internet for the
    LAN here. The other cable modem has a normal 120volt power cord that
    plugs into the back of it. It has a small internal transformer and
    supporting AC to DC switching circuitry.
    Nah. We have cell phones too. I've never depended on voice over IP
    for critical things.
    Just be sure it provides the proper voltage, amperage, and is the
    correct polarity. You don't want the previous one to be positive on
    the tip and the next one to be negative on the tip. Your device won't
    appreciate that.
    Which is what usually kills electronics. ;p
    Physical size doesn't guarantee longevity. The internal components
    and circuit designs do.
    Why? Just ask for another cable modem, it'll come with another power
    supply if it needs it, or a cable to plug it directly into your
    220volt (You aren't from the states and your power plug isn't blade
    style, but round prong, so I'm assuming your 220volt on your outlets.
    We're 110-120volt here).
    Your computer if improperly used is no different. [g]
    How so? I suppose if the battery pack exploded and you had it to your
    head at the time, and the explosion was violent, it could possibly..
    injure or kill you... but, I haven't actually observed this nor have
    I read about it happening from reliable sources.

    Radio waves probably aren't exactly beneficial to be so close to your
    head either, but.. I don't have anything solid either way on that.
    I really have trouble understanding you at times. It could just be a
    language barrier issue though.
