Adding a Mac address to your router is an essential step in securing your network and ensuring that only authorized devices can connect. In this tutorial, we will guide you through the process of adding a Mac address to your router using simple and easy-to-follow steps.

What is a Mac Address?

A Media Access Control (Mac) address is a unique identifier assigned to each network interface card (NIC) or wireless network adapter. It is a combination of six pairs of alphanumeric characters (0-9, A-F), separated by colons or hyphens. Mac addresses are used by routers to identify devices on the local network.

Step 1: Accessing Your Router’s Configuration Page

The first step is to access your router’s configuration page. Open your preferred web browser and enter the default IP address of your router in the address bar.

Typically, this IP address is or 192.0.1. Press Enter to proceed.

Note: If you don’t know your router’s IP address, you can find it in the user manual or by contacting your Internet Service Provider.

Step 2: Logging into Your Router

A login page will appear asking for your username and password credentials. Enter the correct login details and click on the Login button.

Note: If you haven’t changed the default username and password, check the documentation that came with your router or try using “admin” for both fields.

Step 3: Navigating to the MAC Address Filtering Settings

Once you have successfully logged in, locate and click on the Wireless or Advanced tab, depending on your router’s configuration page layout. Look for the MAC Address Filtering option and click on it.

Step 4: Adding a MAC Address to your Router

In the MAC Address Filtering settings, you will find a list of devices connected to your network. Click on the option to add a new device or MAC address.

  • Type in the name of the device (optional).
  • Enter the MAC address of the device you want to add.
  • Click on the Add button to save the changes.

Note: To find the MAC address of a device you want to add, you can refer to its user manual or follow these steps:

  1. For Windows:
    • Press Win + R keys simultaneously to open the Run dialog box.
    • Type “cmd” and hit Enter to open Command Prompt.
    • In Command Prompt, type “ipconfig /all” and press Enter.
    • The Mac address will be listed as “Physical Address” under each network adapter section.
  2. For Mac:
    • Click on the Apple menu and select System Preferences.
    • In System Preferences, click on Network.
    • Select your active network connection from the left sidebar (Wi-Fi or Ethernet).
    • Click on Advanced and go to the Hardware tab. The Mac address will be listed as “Ethernet ID” or “Wi-Fi ID”.
  3. For Linux:
    • Open a terminal.
    • Type “ifconfig -a” and press Enter.
    • Look for the network adapter you want to find the MAC address of.
    • The Mac address will be listed as “HWaddr” or “ether”.

Step 5: Saving and Applying the Changes

After adding the MAC address to your router, click on the Save or Apply button to save the changes. Your router will then update its settings and apply the new configuration. Once completed, your device should be able to connect to your network without any issues.


In this tutorial, we have learned how to add a MAC address to your router. By utilizing MAC address filtering, you can enhance your network security and control which devices can access your network.
