108 Mbps Wireless Router WGT624 v4 Reference Manual
Wireless Settings and Security 2-7
v1.2, July 2007
•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.
•Wi-Fi Protected Access—Pre-Shared Key (WPA-PSK and WPA2-PSK). Provide strong
data security. WPA-PSK and WPA2-PSK will block eavesdropping. Because these are new
standards, wireless device driver and software availability may be limited.
•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 the LAN when
you are away and the others in the household all use wired connections.
Wireless Security Options
The following table identifies the basic wireless security options on the Wireless Settings page.
For a link to a full explanation of these standards, see “Wireless Communications” in Appendix B.
Wireless Security
Option Field Description
None No wireless security.
WEP WEP offers the following options:
• Open System
With Open Network Authentication and 64- or 128-bit WEP Data Encryption,
the WGT624v4 does perform 64- or 128-bit data encryption but does not
perform authentication.
• Shared Key
Shared Key authentication encrypts the SSID and data. Not all wireless
adapter configuration utilities support passphrase key generation.
•Auto
The wireless router automatically detects whether Open System or Shared
Key is used.
WPA-PSK WPA2-PSK • WPA-Pre-shared Key does perform authentication.
• WPA-PSK uses TKIP (Temporal Key Integrity Protocol) data encryption and
WPA2-PSK uses AES (Advanced Encryption Standard) data encryption. Both
dynamically change the encryption keys, making them nearly impossible to
circumvent.
