Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V
5-2 Optimizing Wireless Connectivity and Security
202-10051-01, March 2005
Implement Appropriate Wireless Security
Unlike wired network data, your wireless data transmissions can be received well beyond your
walls by anyone with a compatible adapter. For this reason, use the security features of your
wireless equipment. The WGR826V Wireless Router provides highly effective security features
which are covered in detail in this chapter. Deploy the security features appropriate to your needs.
Figure 5-1: WGR826V wireless data security options
There are several ways you can enhance the security of your wireless network.
• Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This 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.
• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption will block all but the most determined
eavesdropper.
• WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides strong data security.
WPA-PSK will block eavesdropping. Because this is a new standard, wireless device driver
and software availability may be limited.
Note: Indoors, computers can connect over 802.11b/g wireless networks at ranges of up
to 300 feet. Such distances can allow for others outside of your immediate area to access
your network.
