I'm from Australia.
I have had wifi issues for the last couple of months, only noticed because I was chewing up my cell data at a quick rate.
Have played with the router in everyway possible way. All other devices in my house connect well, but my Ipad will only connect within about a foot of my router. I then paired it to my phone, it connected when close, but as soon as I move away it drops out.
Tested at a mates house with his router, same deal. Works if real close, move away it dissapears.
My next thought was that it could be the antenna?
So I pair the ipad to the iphone via bluetooth, same issue. Pairs when close, move devices apart and it loses connection.
Is my next logical step to get the wifi/bluetooth antenna replaced. Must say the process does not look easy :-(

I don't suppose Apple are going to help me much when the unit is out of warranty.
