Idea for troubleshooting wireless interference part 2

Question: Do you have any other ideas for troubleshooting interference problems with wireless computers in the classroom?

The IT Guy says:
An IT Guy reader wrote that if the classroom lights have been recently changed, as a former reader asking about wireless interference sources noted, the light fixtures and bulbs themselves can be the problem. Troubleshooting in this case is straightforward, easy, and cheap: turn the lights off and see if the same connectivity interference is present. If not, and the problem is identified as a lighting issue the solution may not be a cheap one, but at least the networking mystery will be solved.
