May be you want to change the MAC address of your NIC adapter to test your home network. Here you can find three ways to do this for the eth0 (wifi, ethernet, ….) device:
1. Debian and derived distribution you need to modify the /etc/network/interfaces,
search for the eth0 definitions and at the end of the definitions add the following line:
hwaddress ether 00:11:22:33:44:55 where 00:11:22:33:44:55 is the new mac address you want to use,
then restart the networking services typing the following line: /etc/init.d/networking restart
this is the best way to change the mac address because you have definitively a new mac address:
2. ifconfig
# ifconfig eth0 hw 00:11:22:33:44:55
3. macchanger usage
# macchanger –mac=11:22:33:44:55:66 eth0
to use this command you need to download and install macchanger
