Enable MAC address filtering – Westell 327

You can secure your home network using MAC addresses, unique identifiers found on every Wi-Fi enabled device. When you enable MAC address filtering, only devices that you've enabled can connect to your network.

These steps should only be performed by advanced users.  Read the following instructions completely before proceeding, as failure to accurately and completely perform all steps may result in the loss of connectivity.

Note: You will need to gather the MAC address for all devices you want to access your Wi-Fi home network.  Every device will have a different process to obtain its MAC address.  Refer to your service documentation or manufacturer’s website for detailed instructions.
