Security Basics
Unlike wired network data, wireless data transmissions extend beyond your walls and can be
received by any device with a compatible wireless adapter (radio). For this reason, it is very
important to maintain the preset security and understand the other security features available
to you. Besides the preset security settings described above, your router has the security

Turn Off Wireless Connectivity
You can completely turn off the wireless connectivity of the router. For example, if you use
your notebook computer to wirelessly connect to your router and you take a business trip,
you can turn off the wireless portion of the modem router while you are traveling. Other
members of your household who use computers connected to the router through Ethernet
cables can still use the router.

Disable SSID Broadcast
By default, the router broadcasts its Wi-Fi network name (SSID) so devices can find it. If you
change this setting to not allow the broadcast, wireless devices do not find your router unless
they are configured with the same SSID.

Note:
Turning off SSID broadcast nullifies the wireless network discovery
feature of some products such as Windows XP, but the data is still
fully exposed to a determined snoop using specialized test
equipment like wireless sniffers. If you allow the broadcast, be sure
to keep wireless security enabled.

Restrict Access by MAC Address
You can enhance your network security by allowing access to only specific PCs based on
their Media Access Control (MAC) addresses. You can restrict access to only trusted PCs so
that unknown PCs cannot wirelessly connect to the router. MAC address filtering adds
additional security protection to the wireless security option you have in force. The Wireless
Station Access List determines which wireless hardware devices are allowed to connect to
the router by MAC address. See
