MAC Address Changer allows you to change the MAC address on any network interface on your system.
There are a few ISPs that may require authentication via MAC address or they only allow a device to connect to a network from a specific range of MAC addresses. If you have come up against this then you may need to modify your PC's MAC address to connect successfully.
MAC Address Changer makes the process simple, just unpackage and run the app then choose the Network Connection you wish to modify. Then you can either enter or generate the desired MAC address and click Change MAC. You additionally have the option to quickly restore factory default MAC address.
