How to Connect Wireless to an iPhone
Apple's iPhone smartphone features the ability to connect to both secured and unsecured wireless (Wi-Fi) networks. To connect to a secured network with your iPhone, you must know the network's password or security key. Once successfully connected to either a secured or unsecured network, your iPhone will remember the network and automatically connect to it in the future.
Tap the "Settings" button located on your iPhone's home screen.
Select the "Wi-Fi" option.
Move the switch located to the right of "Wi-Fi" to the "ON" position.
Select the secured or unsecured Wi-Fi network you would like to connect to. Secured networks display a lock icon to the right of the network's name. Also to the right of the network's name is a signal strength indicator for the network. Available networks are assigned one to three bars based on their signal strengths.
Enter the case-sensitive password to connect to a secure network. Skip this step if you are trying to connect to an unsecured network.
Wait while your iPhone connects to the Wi-Fi network. Once connected, notice the check-mark icon located to the left of the network's name, indicating you are now connected to the selected wireless network.
