"Settings" is the grey gear icon--it should be on your iPod's home screen.
 You can turn off your wifi or disable certain wifi settings from this menu.
 When this option is enabled, your phone constantly searches for nearby wifi networks. Turning it off will save you some battery life.
 Using wifi rather than data is easier on your battery, and you'll likely have faster upload and download speeds.
 Your iPod's Network Searching feature should now be disabled!
Open your Settings app.
Tap the "Wi-Fi" tab.
Disable the "Ask to Join Networks" option.
If you are in a location with wifi available, tap the network name to connect to it.
Close your Settings app.
