What should my MAC address be? (now shows 00:00:00:00:00:00)

Solution 1:

Try this from a terminal:

ifconfig

Your MAC address is the one after HWaddr. If it is 00:00:00:00:00:00 I think something is wrong with either the hardware or the driver.

If you somehow erased your MAC-address from the network settings you can get it back by writing this in the terminal:

1. sudo lshw > lshw.txt

2. write password when prompted for it

   this takes approximately 20 seconds.

3. gedit lshw.txt

Now you are looking at a list of all your hardware. But we only want the networking specs. Do a search for "network". A couple of lines under that line, there should be a line like this:

serial: 01:21:ee:de:01:11

Only your numbers will be different. This is the MAC-address. Copy that address, and paste it into the network settings. Then you should have restored your original MAC-address.

Solution 2:

First, open 'System settings'. Then select 'Network', and then you will be able to get it by copying what is after 'Hardware address'. Hope it helped you.
