My hardware MAC address is always 00:00:00:00:00:00 until I manually update 'eth0'. How can I fix this?

I am using Ubuntu 12.04. I use a wired connection. My network MAC address shows as 00:00:00:00:00:00.
When I enter the commands below into a terminal window, it starts working again.
sudo ifconfig eth0 down
sudo ifconfig eth0 hw ether my mac address
sudo ifconfig eth0 up
I have to enter these commands every time I want to use the Internet. How can I fix this?

[main]
plugins=ifupdown,keyfile
dns=dnsmasq
no-auto-default=00:00:00:00:00:00,
[ifupdown]
managed=false
