Turns out it WAS the cable after all.

Here is the same cable but with the PC plugged into my LCD monitor instead:

As you can see, it's even worse! :(

So I tried my desktop PC's cable (which normally goes into the LCD monitor):

Perfect! :D Now to return this "new" cable for a refund. Don't know why
I didn't think to try my existing PC's cable in the first place. Sometimes
you just forget to try things like that, even if told to. Maybe I'm getting
old. :?

I had no idea that a cable could cause such interference. Amazing.

When I took it back for a refund, the guy had no problem doing so, and even
commented "yeah, these cables are pretty bad, not shielded very well." And
I'm thinking, "what the heck are you selling crap for then?" :roll:

Yeah, cables can be the cause of lots of problems.

Wait until you go thru a bad batch with intermittant problems, first the problem is there then it isn't, drove me nuts trying to pin it down. Not exactly the problem you had. I was doing some network interface points for some RF capable lightening detection sensors at the airport. Two days after it was done I get this call from a guy at the airport who tells me that they have been receiving false indications of lightening strikes which I knew to probably be false because the weather was good and not a cloud in the sky but stranger things have happened. Went to check it out, the guy tells me they have been constant for about the last 6 hours, I went to look and nothing at all and the guy says he can't understand it so I start looking around. I looked for about 4 hours checking and testing everything, get to the last point and just about finished with it then get a strike indication. Anyway, it kept moving from sensor to sensor after that all the rest of the day with no certain pattern. In the end I started replacing cables and begin to notice a pattern as I bought the sensors back on line one at a time, the ones I replaced the cables on no longer had false indicators, so I replaced all of the cables. Took all 40 cables back to the dealer then he told me "Oh yeah, we just got something on those. Looks like a bad batch from the manufacturer".
