MAC ADDRESS FILTERING
Think of a MAC (media access control) address as a
universally unique name for any network device. The
address is tied to the device hardware. Some routers

routers will have you select whether the entered MAC

For mobile devices such as phones or tablets, the MAC
address can be found by accessing your device’s settings
and navigating to the About Phone tab. From here,
some devices might have a tab titled Status, where the
MAC address can be found, while others have it readily
available in the About Phone section. On a Mac or PC,
navigate to your device’s network settings page and
open the network and sharing center. Click on your Wi-
Fi connection, and look for Details or Properties. This
area will display lots of information, including your
device’s “physical address,” another term for MAC
address. (On a Mac, it’s called “Wi-Fi Address.”)
