iPhone Can't Connect to Internet via Ad-Hoc Wifi

You haven't mentioned whether you are using wireless or wired network. If wireless, the Iphone should connect to your network using wifi and use the internet. I'm pretty sure you already know this.

Edit: I tried with WPA2-Personal and was not able to connect to my adhoc ICS. It works when i set the security to WEP. I'm not sure why though. Will keep testing.

Could it be the iphone cannot use WPA2-Personal, as this is what my router and W7 wireless security is set to.

Anyone ?

The issue is not with your network but with your iphone!
Your Iphone does not update thru the internet but via sync attached to your system. Is your wifi open or do you use encryption? You must use the settings option in your iphone to select your named network that you want your iphone to link up with, if you use password encryption than the settings option must have the passwors or your network will block the iphone.

The Iphone detects the wireless network like any other wifi devices. Like i have tested, with the adhoc network, my Iphone only detect the adhoc network when the adhoc network is setup with WEP. I just had a quick look at my W7 wireless option. And under Security type, if set to Shared, encryption is WEP.

And a quick look again into adhoc creation, when setting up adhoc network, i see Security type having option of WEP. No encryption option available during adhoc creation. So begs the question, why is W7 adhoc saying Security as WEP and W7 wireless saying Encryption WEP.

aem, connect to the following link for wifi connectivity in Apple Support.

Thanks Adrian, but it doesn't say why my iphone cannot detect SSID with WPA, only works with WEP.

And there is definiately a diffrence between security type and encryption type. As i said when you go to create adhoc connection you only get to choose security and WEP is featured, whereas in W7 wireless, you have WEP coming under Encryption. My W7 wireless doesn't have WEP as a security optrion.

It's not the iphone at fault - it connects easily to ad-hoc wifi when I boot my macbook in OSX (SL). When I try to do the same in Win 7, it connects to the wifi network, but no internet, even though Win 7 says the internet connection is shared...

Can you confirm this to be true or not
