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.

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.
