How to find the MAC address for the network card on your Tivo.
The built in network card has the MAC address written on the outside of the unit somewhere. This information won’t help if you have attached another network card such as a wireless card to your Tivo. Here’s how to find the MAC address for your Tivo.
1. Open the Tivo menu.
2. Select Settings.
3. Select Phone/Network.
The MAC address should be listed on that screen along with the IP address.
