And did I say that I put the modem direct to power? Well, it is on a 50 foot 16 gauge extension cord that is plugged into a laundry room outlet. That outlet is on a double breaker to make it 240.
I guess the old adage that "we learn something new every day" is true, at least for me. I had no idea that the power pack could utilize a 240 volt source. I looked on the back of mine and, sure enough, it says "100-240." Very interesting.
Perhaps someone in here will have an idea about the extension cord, especially with it supplying 240. I know many cords with the standard 125v plug are only rated for 125 volts, but I don't know if that's just because of the plug being a standard 125v plug, or if there is actually a technical aspect that makes the cord itself only be rated for 125 volts.
One thing to keep in mind, though, is that with a 240 volt source in a three pronged plug the ground is that much more important. A standard 125v plug has one hot leg and two grounds, more or less, while 240 volts through a standard 110v plug has two hot legs and only one ground. Make sure both hot legs are getting the same voltage to ground.
BTW, I made an assumption about your knowledge of your home's electricity due to your comment about the breaker. If you aren't quite knowledgeable, please don't mess with anything. The last thing I want is for anyone to get hurt, and especially get hurt due to my advice.
