Graphically, I would do the following to spoof mac address for a specific connected network:

  1. Select the gear icon of the connected network:
  2. Enter the required value in Cloned Address Field

Now, how can i do the same from the terminal for a connected network?
Also, i have looked at other posts from askubuntu but none worked. After spoofing the mac and bringing the network up, default settings are seen. I think that is a problem with my network hardware - Intel. Also Intel mentioned in their website that Intel does not support this practice of mac spoofing (They have removed the official link but here is a link to the Superuser discussion page).
I think linux spoofs mac in a different way without actually requiring much of hardware level access. So if you can give me the location of the file where the value of Cloned Address is saved, maybe i can change the address by changing the content of that file.

    None of the solutions worked for me. After spoofing the mac and bringing the network up, default settings are seen. I think that is a problem with my network hardware - Intel. Also Intel mentioned in their website that **Intel does not support this practice of mac spoofing** ( [Superuser discussion page](https://goo.gl/xh1gWj)). I think linux spoofs mac in a different way without actually requiring the hardware level access. So if you can give me the _location of the file_ where the value of **Cloned Address** is saved, maybe i can change the address by changing the content of that file. – Ankit Koirala Jan 25 '17 at 10:24

You can check the changes in the file relative to your connection, on:

/etc/NetworkManager/system-connections/

probably

/etc/NetworkManager/system-connections/Gauri_1.nmconnection

If you want to change the MAC of the interface:

$ ifconfig <interface-name> down
$ ifconfig <interface-name> hw ether XX:XX:XX:XX:XX:XX
$ ifconfig <interface-name> up

Or if you want to change the 'Cloned Address' option (better approach imho): 

$ nmcli c down "Gauri_1"
$ nmcli c modify "Gauri_1" wifi.cloned-mac-address XX:XX:XX:XX:XX:XX
$ nmcli c up "Gauri_1"

Changing the 'Cloned MAC Address' is usually a better option then changing the interface MAC address directly, depending on your network card it can be blocked.
