Where can I find the HFC MAC address on my TM822G/CT & TM822R modem?


When provisioning the modem, the Cable service provider may request the MAC address of the modem.  The label on the bottom of the TM822G/CT & TM822R contains the Media Access Control (MAC) address, a unique, 48-bit value permanently saved in ROM at the factory to identify each Ethernet network device.  To receive data service, the HFC MAC address is also known as the CMAC Address will need to be provided to the Internet Service Provider.  This document includes the following sections:

  • Locating the MAC Address on the Bottom Panel
  • Locating the MAC Address in the GUI (Graphical User Interface)

Locating the MAC Address on the Bottom Panel

The MAC Address is also known as the CMAC Address can be located on a white sticker on the bottom of the device.
