How to Get WiFi to Work on My iPhone
The iPhone is an Internet, audio and video-equipped smartphone designed and manufactured by Apple. All models of the iPhone feature built-in Wi-Fi connectivity, meeting the 802.11 B/G compliance standards. Wi-Fi drains the iPhone battery even when it's not connected to the Internet, as it continually scans for new networks. Because of this, WI-Fi is sometimes turned off. Turning Wi-Fi back on, scanning for networks and connecting to the Internet can all be performed through the iPhone Settings application.
Tap the "Settings" icon on the iPhone home screen to launch the application.
Tap the "Wi-Fi" menu and slide the "Wi-Fi" switch to "ON." The iPhone will automatically begin scanning for Wi-Fi networks within range.
Tap the entry for the Wi-Fi network you want to connect to in the "Choose a Network..." box.
Enter the Wi-Fi network's passkey if requested, and then tap the "Connect" button. To acquire the passkey, check with the owner or administrator of the Wi-Fi network.
Tips & Warnings
- The iPhone will remember the details of any networks you connect to and establish a connection automatically next time it is in range.
