A MAC address contains 12 characters, with digits from 0 to 9, and letters from A to F. The letters may be either upper or lower case. Sometimes each pair of characters is separated by a colon, dash or a space. Sometimes there is no space at all.
For an external wireless card, check the card to see if the MAC address is recorded on a label.
If your computer has an internal wireless card, you'll have to use the operating system to find the MAC address.
- Click on the Start Menu, then select the Run item.
- Type cmd in the text field.
- A terminal window will appear on the screen. Type ipconfig /all and return.
- There will be a block of information for each adapter on your computer. Look in the description field for wireless. The Physical Address for that block is your wireless MAC address.
- Click on the Apple Menu, and choose the Location menu item.
- Click on Network Preferences.
- Click on the Show menu and choose the AirPort item.
- The AirPort ID is your wireless MAC address.
- In a terminal window type ifconfig and return.
- You'll see a list of interfaces. Your wireless interface will likely be named wlan0 or wifi0. The wireless MAC address will be in the field labeled HWaddr.
- You can also use iwconfig to find your wireless MAC address if you have it installed.
