How to Change Your MAC Address on DD-WRT

By Jedadiah Casey

Ethernet networks use a Media Access Control (MAC) address to identify and communicate with each Ethernet-based device on the network. MAC addresses are 48 bits in length. The first 24 bits represent the manufacturer of the device. The final 24 bits are a number assigned by the manufacturer so that every Ethernet device produced has a globally unique hardware MAC address. There are some cases where the MAC address of one device needs to match the address of another. You can change your MAC address on a router running DD-WRT through the administrative interface.

Step 1

Open a Web browser and then type the IP address of the router into the address bar. For example, type "" and then press "Enter."

Step 2

Click the "Setup" tab. Enter the router's user name and password, if prompted.

Step 3

Click "MAC Address Clone."

Step 4

Click "Enable" and then enter the desired MAC address into the "WAN" or "Wireless" field to change the MAC address of each device, respectively.

Step 5

Click "Apply Settings" to save the changes.
