Troubleshooting an iPhone 4 connected to wifi, but can't connect to the internet I recently got an iPhone 4. At home, it connected to our wifi and worked perfectly. Now I am at school. My iPhone is now connected to the wifi here, it says that it is connected and has strong wifi signal. However apps that require internet like email, Facebook app, and online games (like words with friends, etc) load and stall showing "updating". All apps are unable to actually update. It shows it is loading for forever. 

What can I do to fix this?
Go to Settings, then Network. Select your network. Click the accessory button to see the network settings.

If you don't have an IP address, scroll down and tap "Renew Lease".

If you have an IP address that is a 168... number, it means you are not getting an IP address from the school's server. You'll need to contact their sysadmins.

Hope this helps.
