Restrict Wireless Access by MAC Address For increased security, you can restrict access to an SSID by allowing access to only specific computers or wireless stations based on their MAC addresses. You can restrict access to only trusted computers so that unknown computers cannot wirelessly connect to the wireless access point. MAC address filtering adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed. Note: For wireless adapters, you can usually find the MAC address printed on the wireless adapter.  To restrict access based on MAC addresses: 1. Select Configuration > Security > Advanced > MAC Authentication. The MAC Authentication screen displays. (The following figure shows one example.) Wireless Configuration and Security 53
