>>>I have learned over the years, regardless of what the experts say, keep it away from microwaves, ovens, lights, power sources, et al... (I spent numerous hours re-running cable in small insurance agencies and other small businesses as a last resort in troubleshooting only to find out that the "guaranteed certified" cable and where it ran "by the guaranteed certified installers" really was the problem)

>>The worst offender are the X-ray machines, and a few other pieces of medical laboratory equipment that we weren't able to exactly pinpoint, but I know the network in one microbiology lab never really worked right. It was in the days of the coaxial cables, and true, these were a tad long, but we had even longer ones in other places with far fewer problems. Except once when they were welding near the coaxial cable, and the induction fried all the NICs ;).

Next step: buy a new legal pad (illegal one would do just nicely, but let's keep this neat, OK?). Fill all the pages with the repeated sentence "I will never again do arc welding in the kitchen."
