When iPhone is joined to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows signal strength. The more bars you see, the stronger the signal.

Set iPhone to ask if you want to join a new network: Choose Wi-Fi and turn “Ask to Join Networks” on or off.

When you’re trying to access the Internet, by using Safari or Mail for example, and you aren’t in range of a Wi-Fi network you‘ve previously used, this option tells iPhone to look for another network. iPhone displays a list of all available Wi-Fi networks that you can choose from. (Networks that require a password appear with a lock icon.) If “Ask to Join Networks” is turned off, you must manually join a network to connect to the Internet when a previously used network or a cellular data network isn’t available.

Forget a network, so iPhone doesn’t join it automatically: Choose Wi-Fi and tap next to a network you’ve joined before. Then tap “Forget this Network.”

Join a closed Wi-Fi network: To join a Wi-Fi network that isn’t shown in the list of scanned networks, choose Wi-Fi > Other, then enter the network name. If the network requires a password, tap Security, tap the type of security the network uses, and enter the password.

You must already know the network name, password, and security type to connect to a closed network.

Some Wi-Fi networks may require you to enter or adjust additional settings, such as a client ID or static IP address. Ask the network administrator which settings to use.

Adjust settings to connect to a Wi-Fi network: Choose Wi-Fi, then tap next to a network.

VPN

This setting appears when you have VPN configured on iPhone, allowing you to turn VPN on or off. See “Network” on page 143.

Notifications

This setting appears when you’ve installed an application from the App Store that uses the Apple Push Notification service.

Push notifications are used by applications to alert you of new information, even when the application isn’t running. Notifications differ depending upon the application, but may include text or sound alerts, and a numbered badge on the application’s icon on the Home screen.

You can turn notifications off if you don’t want to be notified or want to conserve battery life.

Turn all notifications on or off: Tap Notifications and turn notifications on or off.
