Your pc does not have a MAC address - only the network interface cards (NICs).
Use /sbin/ifconfig. It will be different for wireless than for wired, and will
not show up for wireless unless you are connected.

One of several ways:

/sbin/ifocnfig |grep HW

For just eth0:

/sbin/ifconfig |grep HW

And how do i change the mac address of my laptop’s wireless adapter? I want to see if the mac address filter on my wireless router works…

Look for HWaddr in the output of:

/sbin/ifconfig

When in doubt, use brute force.

In general

ifconfig [interface name] hw ether [new MAC address]

From a terminal, become root with ‘su -’ command. Enter root password when prompted. Then you could do something like:

#ifconfig eth0 down
# ifconfig eth0 hw ether 00:80:48:BA:d1:30
# ifconfig eth0 up

You must disable Network Manager first (if using).
