You may need to find out what the Wi-Fi MAC Address is for your Amazon Kindle so that you can connect to a wireless network that implements MAC Address filtering. Here’s how to find it.
1. From the Home screen, press Menu.
2. Select Settings.
3. The Wi-Fi MAC Address is located toward the bottom of the screen in the Device Info section.
Note: If this field shows “MAC Address not available”, you may have to connect to a Wi-Fi network to be able to see it.
