iPhone disconnects from WiFi when iPhone is idle for more than 60 seconds
Hi
I have got an iPhone 5S which in recent days has been disconnecting itself from my home WiFi whenever the iPhone is idle for more than approx. 60 seconds. During this time, no iMessages or WhatsApp notifications are received. When i press the home button or do something on the iPhone, it reconnects again to the WiFi after a few seconds. This seems to have happened recently as it didn't use to do this. Is it a known fault with a recent software update? I have also tried soft reset and resent network settings, neither of these seem to have fixed the problem.
Thanks
