iPhone 4 Personal Hotspot WiFi

Published Thu, Jun 9 2011 19:17 | Thomas K.H. Bittner

Since iOS 4.3 the iPhone is able to act as an Access Point. Three options are available to use the iPhone as an Internet Network Adapter via USB, Bluetooth and WiFi.

You will recognize that the USB and Bluetooth feature works fine for you. But when you use it as an Access Point and connect it via WLAN the connection is not stable.

When you plug the iPhone with power, you get also stable WLAN connections. But not when the iPhone runs on battery. This could be an issue which is not that obvious until now. So don’t wonder if you run your iPhone on battery and try to use it as an Access Point, it will not work until you plug it with power.

I've had no problems when not plugged in.

What is peculiar is that if you turn on the Hotspot, you have to have a client device login within a minute or so or the hotspot will turn itself off but the UI doesn't show it is off.

Yes I agree with you Robert. UI doesn't says anything if device isn't logged.
