But Why Change MAC Address?

Well, there are several reasons to change the MAC address. Some popular ones are.

Privacy — When you connect to the internet, the web server can not see your MAC address. But other devices on your Local Area Network can. So, if you want to be anonymous on a public WiFi then change your MAC address make sense.

MAC filtering — Most Airlines or Hotels, automatically disconnect the Internet on the devices after some time. They do this by identifying the MAC address. So, if you change your MAC address, you can continue using the internet.

Run Software – Some software detect your MAC address, and send it to their web server. So, if you can not open certain websites (mostly gaming), you may consider changing your MAC address.

So, let’s see how to change Mac address on Windows, Mac OS, Linux, and Android. Or watch this video at the end of this article.

#1 Windows

Since most of us have more than one network card (like WiFi and Ethernet etc), there will be multiple MAC address on your computer. So first, you need to find out which MAC address we want to change.

Find MAC Address in Windows

To do this, open up cmd, and type in the following command and hit enter.

Scroll down the list, and you’ll see a couple of Physical Addresses (in Windows MAC address are called Physical address). Now, the one that has an IP address link to it is the one you are using right now. If you are using the Internet from WiFi, it’ll be the MAC address of the WiFi adapter.

Now, write down that MAC address, we’ll need them later on.

Change MAC Address on Windows

You can change the MAC address in Windows directly from GUI. So, open up

So, open up device manager by typing devmgmt.msc in the Run box. A new window will open, there go to the network adapter and expand it. Find your Wireless Network card and right-click on it then click properties. Another new window will open, click on the Advanced tab and select Network Address. Then click the value button and enter the new MAC address, without any special character or colon in between.

I suggest you copy paste your old MAC address (the one you have written down in the previous step) and replace the last two digits. This is a good practice as it’s easy to remember your new MAC address and don’t cause any conflict on the network.

Also, if the value tab is unclickable, it means your network card doesn’t allow changing MAC address.

To check, if you have successfully changed your MAC address, again open up cmd and do ipconfig /all. You should see new the new MAC address this time.

Note: Changing MAC address is temporary. If you restart your computer, it will automatically switch back to the previous MAC address. But, if you want to keep the MAC address permanent, use software like Technitium, and checkmark the options that say — Make the new MAC address persistent.

#2 Mac

Changing the MAC address on Mac OS is done using a command line, so see how it works.

Find MAC Address on Mac OS X

Open up the terminal and type in the command ifconfig (the ipconfig command on Windows becomes ifconfig on Mac and Linux OS)

You will see the different MAC addresses of each network adapter. To find out, which one you are using, look for the MAC address that has IP address link to it. This will be your current MAC address. Also, make a note of your interface name like — en0 or en1. We will need this later.

Alternatively, you can find your MAC address by going to the System Preference> Network > Current Connection > Advanced > Hardware.

Change MAC Address on Mac OS X

To change MAC Address on MAC OS, open up the terminal and type in the following command.

sudo ifconfig en1 ether a1:b1:c1:d1:e1:f1

Obviously, replace the a1:b1 part with the MAC address you want to have. And once you are done typing the command, hit enter. Since this is a sudo command, you’ll also have to enter your login password. And that’s it.

Now, to check if you have successfully updated your MAC address, type in ifconfig or go to the network settings in system preferences. You should see your new MAC address there.

Note: Like Windows (or for every OS), changing MAC Address in Mac OS is also temporary. Once you restart your computer, you’ll get back the previous MAC Address.

To make it permanent, you can use some MAC Address Changer Script and put it in your startup folder of your MAC. Something like this, though I haven’t tested it.

#3 Linux

Now since there several version of Linux distros, it’s not possible for to cover every one of them. So, we are going with the popular Linux Mint. Though the steps should be similar, for all Debian based OS.

Find MAC Address on Linux Mint

Since Mac OS is built on Linux kernel, the steps for finding and changing MAC address is similar for both. So, to find MAC address on Linux OS, open up terminal and type in the following command.

ifconfig

This will give the MAC Address of all the network cards on your computer. Find the one, you want to change. If you are connected to the internet via WiFi and want to change MAC address of your WiFi card, then look for the MAC address that has an IP address link to it. And write it down, along with the adapter name i.e. — eth0 or eth1 etc.

Change MAC Address on Linux Mint

Now, to change MAC Address on Linux, open terminal and type in the following command.

Replace the eth0 with the name of the Adapter whose MAC address you want to change. And a1:b1.. with the MAC address you want to assign.

So, this first command will disable the network adapter, next we’ll change the MAC address and then restart the adapter once again. To confirm changes, type in ifconfig in the terminal, and you should see the new MAC address.

Note: Like Windows and Mac OS, changing MAC address on Linux is also temporary. So, to make it permanent, go to /etc/network/interfaces and add the following line in the end.

#3 Android

Changing MAC Address on mobile devices are slightly more complicated than Desktop OS. And since Android is also based on Linux kernel, you’ll have to use a sudo command in the terminal. Which means to change MAC address on Android, you’ll need ROOT access. There is no other way.

Find MAC Address on Android

To find the MAC address on Android, go to Settings > About Phone > Status. And look for WiFi MAC address. You can also copy it to the clipboard, by long pressing on it.

Change MAC Address on Android

Now, to change MAC Address on Android, you have two options — either use a terminal app and type in few commands like we did for Linux OS, or use a dedicated app to do that.

For this instance, we’ll go with the simpler method i.e. using a dedicated app. So, go to Play Store and install Change My MAC. Out of many application I’ve tested, this one works quite well.

So, install the app and open it. Now in the app, you can either generate a random MAC address. Or do what I do — copy paste the old MAC Address and replace the last two characters. Next, save changes and that’s it. You have successfully change the MAC address of your Android.

Note: Like the other two, this is also temporary, when you restart your device, your phone will revert to old MAC address. Though unlike the desktop, we don’t restart the Smartphone that often.

iOS

In the recent version of iOS, Apple has made a lot more difficult to change MAC address on iPhone and iPad. You’ll need jailbreak and even then there is no guarantee of success. Overall, not worth it.

Router

There is no big reason why you want to change the MAC address of your routers. But if you want to do it anyway — see if your router supports it or not. If it does, you’ll find clone my MAC address option in the advanced interface settings. Or, you can install a custom firmware (like OpenWRT).

How to Change or Spoof MAC Address

Wrapping up

Usually, changing MAC address is quite simple. All you have to do is type in a few commands from the terminal or use the software. Though do note, that changing MAC address is not illegal, but what you do with can be. And even if you change your MAC address, you are still not anonymous.

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.

There any many instances where someone has blocked your device from connecting to their router, what should you do in that case? Changing the MAC address of your device would definitely work in this case. If you are connected to a WiFi but you don’t want to leave any trace of your presence on the network i.e. you want to protect your privacy, in that situation also you can change the MAC address in Android Devices.If you ISP binds the services to a particular set of MAC addresses but you changed your device, you can change the MAC address to get internet access. Of course, MAC address can be changed for many other malpractices but this guide on changing the MAC address doesn’t promote such illegal practices, it only only meant to give you a insight on the concept.

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.

This was all about changing the MAC in non-rooted mobile phone, for rooted devices you have a bunch of options to select from. Here are a few techniques you can use:

1. Using BusyBox App

We still need a Terminal Emulator for this method. Open the Terminal and then type the following commands:

• su –> This will get you into super user mode
• busybox iplink show wlan0 –> this will pop up the current MAC address
• 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.

2. Using ChameleMAC App

Download and install the app from the link above and follow the steps:

• Open the app, it will ask for root permissions. Just grant it !
• Now, it is way too easy to work on this app. Everything is provided on the main interface of this app.
• Take a note of the Real MAC address of your computer and then go ahead to generate a random MAC address by clicking on the button specified.
• Click on “Apply new MAC”, if you find the generated MAC address good enough or you could generate another random MAC address.
• Once you click apply it, it will ask for confirmation. Go ahead with the change option.

Some Android phones actually don’t let you change MAC address without rooting it, but if you are lucky enough you will get through it. Android system is upgrading with new security features with every upgrade, it is becoming difficult to change the MAC address Android Permanent.
