From what I've read the main behavioral changes are dropping a grade point, falling out with friends, misbehaving in school or increased truancy.
During my day (I'm 22) this was called "falling in with a bad crowd".
For the actual medical symptoms, these are so average run-of-the-mill symptoms that it shouldn't be randomly attributed to wifi. I know in my school my greatest cause of nausea was fresh paint, a stink bomb going off or bad food in the caf.
IMO these parents are ignoring the simplest and most obvious answer: their kids are being kids and their illnesses are them trying to skip school. I had my fair share of nausea when new games came out; I even had a bout of 'nausea' during college when I picked up the Firefly box set (I'm from the UK, never saw it on TV but had a mega-huge recommendation from someone I trusted), I watched 1/4 of the first episode before I called in sick.
