I agree that medical science shows that humans cannot actually hear wi-fi signals! However, my neighbour is adamant that he can, and has featured in several newspaper articles on the subject. The other day I left the ASIAir on for a few days by accident and he reported that he had had the buzzing in his ears. The last time he had mentioned the problem was when we fitted a wi-fi extender, which we now turn off at night as we don't need it then. This time he named the ASIAir as causing the problem, which shows that he had looked at a listing of wi-fi signals on his phone! So the subterfuge of pretending that I have switched it off will not work. The big question of course is whether he is constantly checking to see if there are any new wi-fi signals around, and subsequently believes that he can hear them, or really can detect them and then looks to see what it is. We get on well so I am not going to accuse him of a psychosomatic reaction, but I would love to do a blind test on him! I may discuss this possibility with him.
While I am sceptical, there are genes within us all that are usually switched off -- for example the bioluminescent gene -- but we know that birds, such as pigeons, are sensitive to magnetic fields. So I can't be dogmatic that it is impossible for him to be sensitive to microwaves.
He has agreed, however, that I can use the ASIAir when I wish, as long as I switch it off when I am not using it. So I hope that is the solution.
