NETGEAR RangeMax™ NEXT Wireless Router WNR834B User Manual
2-2 Safeguarding Your Network
v2.1, July 2007
There are several ways you can enhance the security of your wireless network. In order of
increasing effectiveness:
Turn Off the Broadcast of the Wireless Network Name SSID. 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.
Restrict Access Based on MAC Address. You can restrict access to only trusted computers
so that unknown computers cannot wirelessly connect to the WNR834B. 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.
WEP. Wired Equivalent Privacy (WEP) data encryption provides moderate data security.
WEP Shared Key authentication and WEP data encryption can be defeated by a determined
eavesdropper using publicly available tools.
WPA-PSK and WPA2-PSK. Wi-Fi Protected Access with Pre-Shared Key (WPA-PSK and
WPA2-PSK) data encryption provides extremely strong data security, very effectively
blocking eavesdropping. Because WPA and WPA2 are relatively new standards, older wireless
adapters and devices may not support them. Check whether newer drivers are available from
the manufacturer.
Turn Off the Wireless LAN. If you disable the wireless LAN, wireless devices cannot
communicate with the router at all. You might choose to turn off the wireless LAN when you
are away or when other users of your network all use wired connections.
