Hi. I have an iPhone 5 and am on Optus cable in Australia. I understand with my iphone5' 'hey Siri' only works when I am charging the phone. What I don't understand is with hey Siri active and the phone on charge, why my cable modem internet activity light rapidly flashes continuously (example all thru the night' ie 'forever', and my other devices seem to loose nearly all bandwidth. When I turn 'hey Siri' off, the problem seems to stop. Is 'hey Siri' continuously pinging apple?. I usually have about 20 down and 1 up. Thanks for any advice. Glenn.
