How can I tell if my 4S is connected using WiFi N?
I just replaced my A/B/G router with a A/B/G/N router.
I had problems with the 4S disconnecting from WiFi on my old router - and could only reconnect after 4S hard reboot.
Most routers have a status screen that will show currently connected devices, along with mode/speed information. Check your router documentation or just browse around the router interface (while your iphone is on and connected to wifi).
