How do I set up MAC address filtering?

Every wireless and wired network device has a unique identifier called a MAC (Media Access Control) address. Your BT Business Hub reports which devices are connected according to their MAC addresses. By setting up MAC address filtering, you can choose which devices are allowed to access your Hub and which are not.

However, this step is pretty advanced and can cause problems accessing your hub in future. As a rule of thumb if you're not familiar with how to find out your device's MAC address we'd recommend that you don't make these changes unless you're extremely concerned about security.

To manage your MAC addresses:

  1. Open your web browser and type or http://btbusinesshub.home into your address bar. Tap the Enter key on your keyboard.
  2. Click the Settings tab.
  3. Enter in your admin password and click on Ok. If you've not changed this you can find it on a card slotted into the top of your hub.
  4. Select the Advanced Settings and then Continue to Advanced Settings.
  5. Click to select the Wireless tab and then MAC filtering.
