How to Make Wi-Fi Work Better on the iPhone 4

Make Wi-Fi work better on the iPhone 4 to optimize your use of the Internet on the device when your cellular data connection isn't working fast enough. When you switch the iPhone 4's Wi-Fi adapter on, you can connect the device to any available wireless network nearby, much as you would a laptop computer. As is the case with computers, however, the speed of your iPhone 4's Wi-Fi connection depends on several factors.

Instructions

1. Know the location of the wireless router whenever possible -- and move yourself and the iPhone 4 as close to it as you can. The closer you are to the source of a wireless signal, the better your phone receives it and the faster your Internet connection is.

2. Use an encrypted network -- one that requires a password -- if one is nearby and you know the password. While anyone can log on to a network that doesn't require a password, thereby increasing the number of people using the same bandwidth, encrypted networks are open to fewer users, which means each user enjoys a quicker connection speed.

3. Reset the wireless adapter if your connection experiences problems. Tap the "Settings" button on the iPhone home screen. Tap "Wi-Fi" and hit the blue "On" button at the top of the screen to toggle the setting to "Off." Wait 5 to 10 seconds and hit the grey "Off" button to turn on the Wi-Fi.

4. Connect to a secondary network if your first choice becomes unavailable. If you access the Internet on the iPhone 4 using a network that isn't your home or business connection, signal strength and consistency may be unreliable.
