Charges

• Wi-Fi connections, such as home networks set up with routers, are often free of charge. This feature makes Wi-Fi an attractive feature for iPod Touch owners, who don't need a data plan to surf the web. However, some networks, oftentimes those of coffee shops, charge a fee.
  
  

Compatible Networks

• The iPod Touch can connect to wireless networks running 802.11 B or G bands. These are the most common home networking bands, as of 2010. The closer you are to a network's source, such as the router, the faster your connection will be. The connection strength is indicated by the blue bars in the status bar.
  
  

Features

• Once connected to a wireless network, the iPod Touch can surf the Internet on its built-in Safari browser, play videos, and download apps or media off the online iTunes Store.
  
  

Power

• When enabled, using Wi-Fi puts a strain on the battery, meaning battery life greatly decreases while connected to a network. Conserve the battery by turning Wi-Fi off in the "Settings" menu from the home screen.
  
  

Joining Networks

• The iPod Touch can join wireless networks similarly to any Wi-Fi-enabled device, such as a laptop. You can view wireless networks in the area and then manually select which network to join. Afterward, you may be prompted to enter a password, depending on the network's settings.
