3G or Wi-Fi?

Wi-Fi is the preferred way to connect your iPad to the Internet. It’s also, usually, the only way for those of us who own an iPad 2 Wi-Fi model rather than an iPad 2 Wi-Fi+3G model.

Wi-Fi is another name for a wireless local area network, or WLAN. A WLAN works via hot spots, the name for a wireless router that sends out and receives radio waves that are modulated to send and receive data to the Internet.
