Hi I have an iPhone 5 running iOS 6 and I tether it to my Macbook Pro using the Personal Hotspot setting. I do this just over USB directly into the Macbook, not WiFi or otherwise. From time to time, the phone will continue to say 'Personal Hotspot: 1 Connection' at the top of the screen in blue, however I will loose my internet connection. My iPhone always has full signal and I get very good 3G reception where I am. Is it a known issue that the iPhone cuts out personal hotspot connections? Any help or clues appreciated as this drives me nuts. I either have to switch the hotspot on and off or unplug and re-plugin my iPhone to restore the internet connection. Hope you can help, any way of fixing this? Thanks.
