I now have a phobia from my iPhone's wifi. Last year I had an iPhone 4S and in February 2013 I updated it to iOS 6 through OTA and lost my wifi (greyed out) so I've been living with the hair dryer trick for 1 year until last month I finally decided it to trade it with a used iPhone 5. At first, I thought my problem was solved. But hahahaha I laugh a lot at my luck. It's quite known that the iPhone disables wifi when the screen is locked unless it is connected to a power source. My iPhone 5 still disconnects from my wifi even while it's charging I'm on iOS 7.0.4 with Cydia installed and a tweak called Insomnia which keeps the wifi always enabled and it actually works, but that doesn't take my worries about my wifi away, in addition to the tweak's battery draining. Is anything wrong with my Wifi? I tried resetting network settings, it worked for a couple of hours but still it disconnects a lot and I really get mad when Push notifications don't show on my lockscreen cause of the wifi Any solutions?
