If you’re blocked from a network because of some MAC address filter that is set on a modem, router or firewall, you may want to spoof your MAC address so that the network will recognize your device and grant you access to connect. This article explains how you can spoof MAC addresses on a Windows machine.
DISCLAIMER: It is completely legal to spoof a MAC address on a Windows machine and this can be done with built-in Windows utilities (no need for third-party software). If you use the instructions here to spoof your MAC address for malicious reasons, I cannot be held responsible.
What’s A MAC Address?
A Media Access Control (MAC) Address is a unique identifier attached to every Network Interface Card (NIC).
NICs are also known as network adapters, LAN adapters, etc.
The MAC address of each network adapter acts as a unique name for that particular network adapter. So in theory, no two network or Ethernet or wireless adapters SHOULD have the same MAC address. A MAC address is also called a Physical Address and they are hard coded into the actual hardware of network cards. Technically speaking, it is not possible to change these physical addresses in hardware. It is however, possible to change or spoof the mac address in the operating system and this is what we’ll be doing here.
How To Find Your MAC Address
To find the MAC addresses of all network adapters on your machine, first open a command prompt (press Win+R, type cmd, press Enter).
In Windows 8, press Win+X and select Command Prompt from the menu.
Now type getmac /v /fo list and press Enter. The configuration information for all your network connections will be displayed. Like this:
If you just want to see the MAC address of your current active connection, Go to Control Panel >> Network and Internet >> Change Adapter Settings (Or just type ncpa.cpl into the start menu and press Enter). Now Right-Click on your active connection and select “Status”.
On the window that opens, press the “Details” button. You’ll see the MAC address (Physical Address).
How To Change A MAC Address
Go to Control Panel >> Network and Internet >> Change Adapter Settings (Or just type ncpa.cpl into the start menu and press Enter).
A list of all network adapters on your machine will be displayed.
Now Right-Click on the network adapter you want to spoof and press “Properties”.
On the Networking tab, press the “Configure” button. On the window that opens, select the Advanced tab and look for the Locally Administered Address option (or the Network Address option in some cases). By default, the Not Present value will be selected.
Click on the Value option and enter a new MAC address.
NOTE: By convention, MAC addresses are usually written either like this MM:MM:MM:SS:SS:SS or like this MM-MM-MM-SS-SS-SS (The M part is the ID of the manufacturer and the S part is the serial number assigned by the manufacturer to the adapter). When entering a new MAC address in the Value field above, ignore the dashes/colons.
Restart your computer to make the changes take effect. When you check your MAC address after the reboot, the new value you set will be displayed.
