How to Find Your MAC Address?

MAC Address or Media Access Control Address is an address that is associated with the hardware of the network adapter. Just like the IP address which is associated with the networking software, MAC address is associated with the hardware of every NIC or Network Interface Card.

Whenever a network adapter is manufactured, it is given a MAC address by the manufacturer which is hardwired onto the network adapter. For this reason, it is also called as Physical Address of a device. It is unique for every network adapter.

At times, it becomes important to find out the MAC or Physical Address of the devices connected to your Wi-Fi network. Not only is MAC Address important to allow or block certain devices from connecting to your WiFi network but it is also important to identify a device that has been registered to your Xfinity account.

So, you should know how you can find your MAC address. Some people may think that find out MAC addresses may be a complicated process but actually it is not.

Once you learn how to find out your MAC address, you can then identify the devices connected to your Xfinity WiFi Network using their MAC addresses and also allow/block certain devices from connecting your WiFi Network using the MAC Filtering feature.
