Warning, don't fry your modem.

  Some years ago, an EMT vehicle backed over and destroyed my Hughes dish. The next morning I called my trusty tech company, and the first thing he asked me was if the coax was damaged, and next if h...

    Yes, there is DC power supplied by the modem going through the coax to power the radio on the dish. Under certain situations the modem can be damaged if the power is shorted out. There are protections built in but they don't always work.

     

    Also one reason we say to power down the modem from the wall receptacle, not the plug on the back of the modem.

  Given the behavior of my tech guy I would guess that they seldom work, because he was absolutely sure that I was going to need a new modem.

 

  There's obviously a lot more happening on that one piece of coax than I ever thought there would be.   BTW I hate coax.  The first computer network I worked with,  was coax run overhead on already existing poles.  It was an absolute nightmare to keep working.   After we had done about everything that we could think of to try to fix it.  I told my supervisor the only thing we could to do now was to change all the poles.  :>)>

    lets be honest...your modem is supplied power by an AC/DC converter. A cheap one at that. If the modem failed before the converter did...HughesNet needs a new modem manufacturer. Plain, simple, to the point.
