Received my iPhone 4S a couple of weeks ago and have noticed that when I use the 'NZ Herald' app on wifi, and switch out of it to another app, my wifi access point drops out and I have to reset my router to get it working again. This happens across my whole home network making all of my computers unable to access the net. It almost seems to corrupt my whole network. Halting all traffic. I am using a D-Link DSL 502-T modem with a TP Link WR-541G wireless router using wireless G. Some computers are wired and some wireless laptops. It only happens when I use this app. Anybody else having this problem? before I contact their support?
