If you want to add your Kindle Fire to your router's whitelist to ensure you can connect to your network, you'll need to know the device's MAC address. While your IP address changes from network to network, your MAC address is unique to the device. Entering the MAC address of the Kindle Fire into your firewall or router settings will tell the device or software to allow your device to access the Web.

Step 1

Open the “Settings” menu by selecting the gear icon in the upper right corner of the screen.

Step 2

Select “More,” then select “Device.”

Step 3

Scroll down the page until you find the Kindle Fire's MAC address.
