MAC Filtering is a great way to make a WiFi connection more secure. All WiFi devices have a MAC address and MAC address filtering means you have to manually add the MAC of a new device into the router to enable it to connect.

1. Connect the router to your computer via a USB cable or the WiFi connection
2. Launch a web browser and in the address bar, enter http://192.168.1.1/, then press Enter
3. Click LOG IN HERE to access settings
4. Enter your username and password, then click Log In
5. Click WLAN
6. Click WLAN MAC Filter
7. Click the WLAN MAC Filter dropdown
8. Select the desired filter mode (e.g. Allow)
9. Click on an empty MAC Address field
10. Enter the MAC address of the device you want to add
11. To remove a device from the MAC filtering list, delete the required address from the MAC Address field
12. Click Apply

MAC filtering has now been enabled or disabled.
