Wireless-N 150 Router WNR1000v2 User Manual Table 2-2. Other Features That Enhance Security Security Type Disable the wireless router radio. Turn off the broadcast of the wireless network name SSID. Restrict access based on MAC address. Modify your firewall's rules. Use the Push 'N' Connect feature (Wi-Fi Protected Setup). Description If you disable the wireless router radio, wireless devices cannot communicate with the router at all. You might disable this when you are away or when other users of your network all use wired connections. For more information, see "Viewing Advanced Wireless Settings" on page 2-11. If you disable the broadcast of the SSID, only devices that know the correct SSID can connect. This nullifies the wireless network discovery feature of some products such as Windows XP, but your data is still fully exposed to an intruder using available wireless eavesdropping tools. For more information, see "Viewing Advanced Wireless Settings" on page 2-11. You can restrict access to only trusted computers so that unknown computers cannot wirelessly connect to the WNR1000v2 router. MAC address filtering adds an obstacle against unwanted access to your network by the general public, but the data broadcast over the wireless link is fully exposed. This data includes your trusted MAC addresses, which can be read and impersonated by a hacker. For more information, see "Restricting Wireless Access by MAC Address" on page 2-18. By default, the firewall allows any outbound traffic and prohibits any inbound traffic except for responses to your outbound traffic. However, you can modify the firewall's rules. For more information, see "Understanding Your Firewall" on page 2-22. Wi-Fi Protected Setup provides easy setup by means of a push button. Older wireless adapters and devices might not support this. Check whether devices are WPS enabled. For more information, see "Using Push 'N' Connect (Wi-Fi Protected Setup)" on page 2-13. 2-4 Safeguarding Your Network v1.0, September 2009
