Chapter 8 Settings 92
Wi-Fi Wi-Fi settings determine when iPhone uses local Wi-Fi networks to connect to the
Internet. If no Wi-Fi networks are available, or you’ve turned Wi-Fi off, then iPhone
connects to the Internet via your cellular network, when available. You can use Mail,
Safari, YouTube, Stocks, Maps, and Weather over a cellular network connection, but not
the iTunes Wi-Fi Music Store.
Turn Wi-Fi on or off
m Choose Wi-Fi and turn Wi-Fi on or off.
Join a Wi-Fi network
m Choose Wi-Fi, wait a moment as iPhone detects networks in range, then select a
network. If necessary, enter a password and tap Join. (Networks that require a password
appear with a lock icon.)
Once you’ve joined a Wi-Fi network manually, iPhone automatically joins it whenever
the network is in range. If more than one previously used network is in range, iPhone
joins the one last used.
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
When you are trying to access the Internet, by using Safari or Mail for example, and you
are not in range of a Wi-Fi network you have 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 New Networks” is turned off, you must manually join a network to connect to the
Internet when neither a previously used network nor cellular network is available.
m Choose Wi-Fi and turn “Ask to Join Networks” on or off. If you turn “Ask to Join
Networks” off, you must join new networks manually.
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 m
Network.”
Join a closed Wi-Fi network (an available Wi-Fi network that isn’t shown in the list of
scanned networks)
m Choose Wi-Fi > Other and 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.
