I don't know why I didn't think about this before, it's not as if I've only just walked into a WiFi world, it's been around for years, but I've just figured out why I get a headache and dizziness with WiFi.

It isn't the device transmitting the WiFi signal, it is the device picking up the WiFi signal. But, how have I figured it out? Well, I've just switched on a new device in the house that is looking for a signal from a hand controller that I've used for a couple of years with no issues and I get the headache and dizziness again. That and I've just figured out I forgot to turn the WiFi off after a party we had in June.

I posted about this a while ago, after buying a Microsoft LifeChat headset that when turned on would give me a headache but after writing to Microsoft and hearing nothing and then turning WiFi off at home and not using the device, just forgot about it and put it down to experience.

But, I turned on WiFi recently so we could play some music outside, thinking if I was outside I wouldn't get a headache and I didn't, but then I went to bed that night and forgot to turn it off. That was in June, when Johanna had her birthday party and to this day it is still on and I'm not getting a headache. Seeing as we have no devices searching for a WiFi signal, I just forgot about it.

But today, we got a new XBOX 360 because the old one is leaving to get fixed and as soon as I turned it on to sync the controllers, I started to feel a bit sick and sure enough, the headache returned within minutes of the console powering up.

That I am the only one in the family that notices this is a bit of a worry and raises other questions, but and this isn't the right way to be thinking about it, it's a bit like 'out of sight out of mind'. However, saying that, this new XBOX 360 isn't getting switched back on until we figure out why it is causing this issue and I fancy it is the receiver sending out a signal trying to pull one in. We had no issues whatsoever with the older XBOX 360 - just this new one.

So, I've spoken with XBOX support, who have opened up a ticket for me and are escalating the issue to Microsoft. Bottom line, I called wanting to know the difference in components used between the new XBOX 360 and the one we purchased a couple of years ago, hoping that if we could identify the issue, I might be able to get one with something different in and see if that was better.

Basically one XBOX gives me a headache, the other doesn´t. Chances are quite high, extremely high in fact that what is inside the new one isn´t the exact same as what is inside the old one and that is what I need to know, so I know what not to buy again.

They assure me they are going to get back to me and in the meantime, I'm going to phone the shop that is going to fix the old one and I'm going to ask if they have an older XBOX that they can send me instead, because and you knew this was coming; 'out of sight out of mind' and well, you just have to have an XBOX at home as it does so much nowadays and there might even be a way to turn off the receiver if you play with controllers plugged in.

It is infuriating that some devices that search for a wireless signal give me this headache (I don't get it with my Dell Mini 9 although I do with my Dell XPS) and while I'm confident Microsoft will get back to me and I'm sure I can get a 360 with a different component, it is going to be annoying if every time I purchase a device that sends out a signal, I've got to make sure it isn't carrying some hardware that gives me a headache.

Questions raised and one with Microsoft, so hopefully I'll get an answer soon and maybe another 360 so Oskar (okay, not just Oskar) can play his games but it does concern me that I get a headache and others don't, because something is clearly getting sent out and well, it is doing something.
