Netgear WN203 - ProSAFE® WIRELESS-N SINGLE BAND ACCESS POINT 사용자 설명서

Click the Apply button.

For increased security, you can restrict access to a wireless network by allowing access to 
only specific computers or wireless clients based on their MAC addresses. You can restrict 
access to only trusted computers so that unknown computers cannot connect wirelessly 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.
