I'm having problem connecting my Laptop & iPad Mini to my tethered iPhone 5 EE through WiFi. I've to toggle the hotspot off\on many times before it shows on my devices. Also, if connect and I walk a far distance from my device and come back, it won't connect again. I'll have to toggle it to work. But, usb connect is fine. I tried the hotspot on my friend's iPhone 4S running iOS 5.1.1 and it's all fine. Is this an iOS 6 issue?
