Media Access Control is a unique ID consisting of 12 digit hexadecimal numbers. It comes already hard-coded on your mobile system. This identifier helps to distinguish a specific device over the cluster of devices connected to a particular network. If you are surfing the web from your Android phone using a WiFi network, the network adapter of your WiFi devices must have a MAC address to set up the connection and transfer data over the network. MAC address looks something like this XX::XX:XX:XX:XX:XX, where each X is a hexadecimal character i.e. ranges from 0-9 or A-F. A possible MAC address could be, 1A:2B:3C:4D:5E:6F where the first 6 digits find your manufacturer and the last six digits find your network interface card.

To change back to your normal MAC Address, just follow these steps to change it back or restart your phone. It makes this easier if you already know your real MAC Address which can be found at: All Programs Settings Wireless & Networks WiFi Settings Menu button Advanced.

There any many instances where someone has blocked your device from connecting to their router, what should you do in that case?

If your Android device is rooted, you can easily change the MAC address of the device but what if it is not? Don’t worry we have a trick to change the MAC address without rooting your android device. For changing the MAC address permanently, you will have to root your device. However, if you just want to have it temporary changed, you don’t need to root your device. But before moving on with changing the MAC, let us see how can you look up your MAC address. I strongly recommend to just note down your MAC address before starting to experiment on it. You also need to know the connection name, to get it all follow the steps below:

  1. Open up settings and then go to WiFi.
  2. Now, you will see a gear on the top of this screen, click it. But if you don’t see it, look for “Configure WiFi” option and click it. Some Android system have Advanced option in WiFi, MAC address can be found there also.
  3. Voila ! You can find the MAC address on the bottom of this screen. Keep a note of it.
  4. In order to get the interface name, you will have to install Terminal Emulator for Android. Go to Google Play Store and download it or click the link to get it.
  5. Once you download it, install it and open up.
  6. Type the following command : ip link
    1. You screen will be filled with lot of information, useful and useless. Now, remember I told you to keep a note of your MAC address. Just look for this MAC address under “link/ether” for all the cases.
    2. The one that matches our MAC address, is the connection name. For most of the devices it is either “wlan0” or “eth0”.

Now, that we know our MAC address and the connection name, we can go on to change the MAC address with this terminal emulator only. Before that you should have a valid MAC address in your mind or generate one from this link. Once, you have a new MAC address, just get on with the below steps:

  • Launch the Terminal Emulator
  • Just type the following command: ip link set wlan0 address XX:XX:XX:YY:YY:YY, where wlan0 is the name of the interface and XX:XX:XX:YY:YY:YY is the MAC address you want to set.
  • Important thing to keep in mind that the manufacturer name should be kept unchanged while changing the MAC address i.e. XX:XX:XX (first 6 digits) should be same as before, otherwise you might face a lot of authentication issue.
  • This is only a temporary change and when you restart your device, your previous MAC address will be retrieved back.

  • busybox ifconfig wlan0 hw ether XX:XX:XX:XX:XX:XX –> configure the new MAC address
  • busybox iplink show eth0 –> this is to check whether the MAC address has been changed or not.
