NetZero DataShield will work with any supported device regardless of how it is connected to the Internet, but NetZero DataShield will only work with the individual devices on which it is installed. NetZero DataShield cannot be used on a wireless router to cover multiple devices at once. So if you have three devices sharing a wireless connection, only the devices on which NetZero DataShield is installed will be protected.

However, since NetZero DataShield creates a secure, private tunnel by which your device connects to the Internet, using it on a device connected to your home network means that you will no longer be able to use any of your other network connections, such as a printer or file-sharing.
