How to Change the MAC ID on a Router


A MAC address is also known as Media Access Control. Every network adapter has a unique 12-character MAC address assigned to it. Some ISPs use the MAC to authenticate your internet service. Changing a router or computer sometimes causes connection problems. Since the MAC number is associated with a piece of hardware, it can’t physically be changed. However, you can use emulation software to make the MAC address appear changed. This process is known as cloning and is supported by most modern routers.

  • Log in to your Router's admin panel. This can be accessed by opening a web browser and typing in the router's default IP address. Different brands have different numbers so check your manual (i.e., Linksys uses "" as the default IP).

  • Enter the user name and password at the prompt. If you have not assigned any, check the router manufacturer's web site for the default username and password (Linksys uses "admin" as both the admin name and the password).

  • Go to the router's Mac setup tab. For Linksys users it will be under "MAC Address Clone" and also might be under the "Filters" section.

  • Click “Enable” if necessary, and enter in a new MAC address in the blank field.

  • Click "Clone" or "Clone your PC's MAC" and save the router settings.
