Set up MAC authentication on your modem

MAC authentication allows you to limit who can and can't connect to your WiFi network by allowing or denying devices by their media access control (MAC) address.

NOTE:  Depending on your model, your modem's user interface may appear slightly different from the images below.

5.  If given the choice, select "2.4 GHz" or "5 GHz" in the left sidebar. Some models do not offer this option. Read more about the how to choose between 2.4 and 5 GHz frequency, and learn which modems have this capability.

6.  Select "MAC Authentication" in the menu on the left.

7.  Select your wireless network (SSID). Your active network will usually be the one at the top of the drop-down list.

8.  If you are setting up MAC authentication, select "Enable."

9.  Set the list type to "Allow" or "Deny." This determines whether the MAC addresses you enter in the next step will be allowed to access your network or forbidden.

10.  Enter the MAC address (or select a device from the drop-down) that you want to allow deny, depending on the "list type" set in step 

11.  Select "Apply" to save your changes.
