Set Up iPhone Wi-Fi

  1. Tap "Settings" on the iPhone home screen. The Settings icon looks like a gray gear.
  2. Tap "Wi-Fi" in the first group of options toward the top of the Settings window.
  3. Tap the "ON/OFF" toggle to the right of Wi-Fi at the top of the Wi-Fi Networks window until "ON" is displayed in blue. A list of available wireless networks appears beneath Choose a Network.
  4. Tap the name of the wireless network you want to join. If you don't know the name of your wireless network, check your wireless router or the user manual that came with your router for the default network name. If you can't find the manual, stand as close to the wireless router as possible with your iPhone on the Wi-Fi Networks screen. Your wireless network will be the one with the strongest signal. The signal strength can be determined by looking at the signal icon to the right of the name of the listed networks that has three bars; the more dark bars, the stronger the signal.
  5. If there is a padlock icon to the right of the name of your wireless network, the network is password protected and you'll need to enter the password after selecting the wireless network; if there is no padlock, then you'll be granted instant access to the network and you won't have to worry about entering a password. If you don't know the password associated with your wireless network, consult the user manual that came with your wireless router. Tap "Join" after entering your wireless password.

Forget iPhone Wi-Fi Network

After connecting your iPhone to a wireless network, your iPhone will remember that network and automatically connect to that network when it's within range in the future. If you no longer want to connect to a specific Wi-Fi network, you can tell your Wi-Fi to forget that network so that it doesn't connect automatically:

  1. Tap "Settings."
  2. Tap "Wi-Fi."
  3. Tap the right-pointing blue arrow to the right of the Wi-Fi network you want your iPhone to stop logging in to automatically.
  4. Tap "Forget this Network" at the top of the iPhone screen.
  5. Tap the red "Forget" button at the bottom of the iPhone window to verify that you want your iPhone to stop automatically connecting to that Wi-Fi network. You can still see the Wi-Fi network in your list of networks, but your iPhone will no longer connect to it automatically.

Enable and Disable iPhone 3G

Upon inserting a SIM card into your iPhone and activating your device through a cellular provider, 3G access will automatically be enabled on your iPhone. However, you have the power to turn 3G on and off on your own by doing the following:

  1. Tap "Settings."
  2. Tap "General," which is located at the top of the third group of options.
  3. Tap "Network."
  4. Tap the "ON/OFF" toggle to the right of Enable 3G to turn 3G on and off. When the toggle displays "ON" with a blue background, 3G is turned on; when the toggle displays "OFF" with a gray background, 3G is turned off.

Airplane Mode

Airplane mode is a quick way to ensure that both Wi-Fi and 3G are turned off quickly. You can toggle Airplane mode on and off by doing the following:

  1. Tap "Settings."
  2. Tap the "ON/OFF" toggle to the right of Airplane Mode until "OFF" is displayed to disable Wi-Fi and 3G if they are not already disabled. Tap the toggle again until "ON" is displayed to activate any Wi-Fi and 3G networks that were enabled prior to enabling Airplane mode.
