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.
