Iphone 5 Wifi keeps disconnecting whilst on lock.
I recently bought my iphone 5 and managed to hook it up to my router pretty easily, get good connection and internet speed but when ever I lock my iphone and put it in my pocket or on my desk for more than 30 seconds the wifi drops off. I then have to go back into settings and manually reconnect my iphone in order to use the wifi.
I have fiddled about with some of the settings and found that when i turn mobile data and 3g off this problem doesnt happen anymore which is odd. Further to this my family members also have iphone 5's yet their connections do not drop out whilst on hold.
Has anyone else had this problem or found a solution?
iPhone 5, iOS 6
