Comment 23 for bug 787192

Hi, i solve this problem stoping netwok-manager service, disabling the network inreface, then changing the mac, enabling the interface and finally restarting the network-manager service

Here the step by step (need root)

service network-manager stop
ifconfig $1 down
ifconfig $1 hw ether $2 up
service network-manager start

where $1 is the network interface and $2 is the new mac adress

Ex:
# service network-manager stop
# ifconfig wlan0 down
# ifconfig wlan0 hw ether DE:AD:BE:EF:CA:FE up
# service network-manager start
