How to set up the MAC address filtering function

With the rapid development of the Internet, more and more families and businesses are beginning to use routers to share the network to meet their respective Internet needs. In order to ensure the security and stability of the network, many routers are equipped with MAC address filtering function. So, what is the MAC address filtering function and how to set it up? This article will give you the detailed answer.

First, let’s understand the role of the MAC address filtering function. The full name of MAC address is Media Access Control Address, which is a unique identifier fixed on the hardware of each network device when it leaves the factory. The router's MAC address filtering function can limit only specified MAC addresses to connect to the network, and other MAC addresses cannot connect.

Before setting the MAC address filtering function, we need to log in to the router’s management page. Generally speaking, we can access the management page by entering the router's IP address in the browser address bar, such as 192.168.1.1 or 192.168.0.1, etc. After entering the username and password correctly, we can enter the router’s management interface.

Next, we can follow the following steps to set up the MAC address filtering function:

Step 1: Find and open the MAC address filtering setting page
In the management interface of the router, we can Find an option called "MAC Address Filtering" or "Wireless Access Control", usually located in the "Wireless Settings" or "Advanced Settings" menu. Click this option and we can enter the MAC address filtering settings page.

Step 2: Enable MAC address filtering
In the MAC address filtering settings page, there is usually an "Enable" or "Switch" option to turn on or off the MAC address filtering function. We set it to "Enabled" and click on the Save or Apply button.

Step 3: Obtain the MAC address of the device to be allowed to connect
After enabling the MAC address filtering function, we need to obtain the MAC address of the device to be allowed to connect to the network. We can obtain the MAC address of the device in the following ways:

1. Search in the network settings or menu of the device
The MAC address of the device will be displayed in the network settings or menu of most devices. We can find and record them in these places.

2. Use network scanning tools
We can also use various network scanning tools to scan devices in the LAN to obtain their MAC addresses.

3. Check the physical label of the device
Some devices will have a physical label attached to the back or bottom of the device, which will indicate the MAC address of the device.

Step 4: Add and edit the MAC address of the device
In the MAC address filtering settings page, we can see an option called "Connected Devices" or "Device List". We need to click on that option and add or edit the MAC address of the device as needed.

For the device to be added, we need to enter its MAC address and device name. Generally speaking, a MAC address consists of 12 hexadecimal digits, which can be separated by colons or dashes, such as 00:AB:CD:EF:12:34 or 00-AB-CD-EF-12-34.

When editing the MAC address of a device, we can choose to allow or prohibit connecting to the device as needed. If you choose to disallow connections, the device cannot connect to the network through the router.

Step 5: Save settings and restart the router
After completing adding and editing the MAC address of the device, we need to click the Save or Apply button to save the settings. Then, follow the prompts on the page to restart the router for the settings to take effect.

Through the above steps, we can successfully set up the MAC address filtering function. After enabling this feature, only MAC addresses that have been added to the device list can connect to the network, and other devices that have not been added will not be able to connect to the network.

It should be noted that although the MAC address filtering function can enhance the security of the network, it does not mean that the network is absolutely safe. Hackers can still use other technical means to bypass MAC address filtering. Therefore, we also need to combine other network security measures, such as setting strong passwords, enabling encryption, regularly updating software, etc., to improve network security.

In short, the MAC address filtering function can limit only specified MAC addresses to connect to the network, thereby enhancing network security. With simple setup steps, we can easily enable and configure MAC address filtering to provide better protection for our network.
