All the ideas are interesting but the problem is not WiFi related.
Video and pictures used to illustrate articles about this incident show what it is, Subliminal Distraction exposure.
Named for the feature in our physiology of sight that allows it to happen, it was discovered and solved forty years ago.
Designers of Systems Furniture, Cubicles, who deal with it see only light exposure and believe it can cause only a harmless temporary episode of confusion.
It happens when you create the situation so that your brain has a massive number of failed attempts to trigger the vision startle reflex.
The cubicle was designed to prevent this by blocking peripheral vision for a concentrating worker by 1968.
These children do not have enough exposure for the full mental event. But if one of them created the same situation at home where they played video games the full mental break might happen.
Turning off the WiFi won't do anything to stop this if they continue to use computers the same way. Students are shown crowded together sitting in each other's peripheral vision without Cubicle Level Protection.
<link removed> is a seven year investigation of Subliminal Distraction.
It's just an odd piece of information everyone should have. Remember, although computers are implicated today it was discovered before they existed.
