A MAC address consists of six groups of numbers or letters arranged as such, D4-FB-6A-7C-31-B4 (just an example.) Once the MAC address has been changed, it will remain as your router’s primary MAC address until you revert the router back to its default factory settings./** * \file cmac.c * * \brief NIST SP800-38B compliant CMAC implementation for AES and 3DES * * Copyright The Mbed TLS Contributors * SPDX-License-Identifier: Apache-2.0 * * Licensed under the Apache License, Version 2.0 (the "License") you may * not use this file except in compliance with the License.

Navigate to the wide-area network (WAN) settings page or a similar settings page (each router may be different.) Once there, look for an option to change the MAC address. If you are lost, check the instructions that accompanied your router. Check your devices to make sure you can get online.Īccess the router’s admin panel via a web interface (browser address bar) or by opening up dedicated firmware software. Make sure your Internet is connected properly, ensuring that the Ethernet cable is going from the modem to the router and that there is an available wireless connection for connected devices. Luckily, this is not an overly difficult task and certainly not as frustrating as, say, learning how to disable IPV6 on a router. When you revert your router to its default settings, the MAC address will also reset to the original setting.
