Your laptop computer has its own unique MAC address which is used to help Wi-Fi networks recognize it. Some wireless networks will restrict access to only computers that are known. The only way to know a computer is through its MAC address. If you do not know your laptop’s MAC address, there is an easy way to find it. Follow these steps to find out how.

Step 1: Click the Start menu and then select Control Panel to open it. The Control Panel menu is displayed.

Step 2: From the Control Panel menu, select Network Sharing Center.

Step 3: Find the link labeled View Status and click it. This will open up a dialog box titled Wireless Network Connection Status.

Step 4: Click the Details button. Find the computer’s MAC address (labeled as Physical Address) and write down that number for future use.

There may be times when you connect to a certain network that the network will prompt you for your MAC address. You or a network administrator can add your laptop to the list of allowed computers by entering your MAC address.

The MAC address itself is a 12-digit number that also includes the letters A through F. It will appear like this: A6:28:F4:75:B3:CE. Again, no two MAC addresses are alike. They are also difficult to fake, so attempting to enter a false MAC address will do you no good. Simply follow the above procedure, write down your MAC address, and save it for when you need it.
