How to spoof Wi-Fi Mac address?

Spoofing MAC Address on Android Devices
Even though Wi-Fi MAC address is embedded on the hardware device during manufacture, it can still be spoofed to input a new one of your choice by a simple trick. Here is a detailed instruction on how to spoof Wi-Fi MAC address on your Android phone.
Before you spoof the MAC address, you need to record the original/current MAC address of your device for backup which can be done according to the instruction below:
On the Home Screen of your phone, tap Menu button and go to Settings.
Tap About Device and go to Status
Now scroll down to record the 12-digit code shown under Wi-Fi Mac address. An address would read something like:

Example MAC address: E5:12:D8:E5:69:97
Requirements for Spoofing the MAC Address:

• Rooted Android Phone
• BusyBox app installed on your phone
• Once BusyBox is installed, you need to install Terminal app

Once the above requirements are satisfied, follow the instructions below to spoof your MAC address:
Step 1) Open the Terminal app and type the commands as listed below:

$ su [HIT ENTER]

$ busybox iplink show eth0 [HIT ENTER]
(This will show your current MAC address, just for your confirmation)

Step 2) Type the following command:
$ busybox ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX [HIT ENTER]
(In the above command, replace XX:XX:XX:XX:XX:XX with your new MAC address)
You have now spoofed your MAC address successfully. To check for the change enter the following command again:

$ busybox iplink show eth0 [HIT ENTER]
(Now you should see your new MAC address)
