Chapter 10 Wireless Security Screen Table 44 Security: WPA-PSK, WPA2-PSK or WPA2-PSK-MIX LABEL DESCRIPTION Group Key Update Timer The Group Key Update Timer is the rate at which the AP sends a new group key out to all clients. The re-keying process is the WPA equivalent of automatically changing the group key for an AP and all stations in a WLAN on a periodic basis. Setting of the Group Key Update Timer is also supported in WPA-PSK mode. The NWA's default is 1800 seconds (30 minutes). Apply Click Apply to save your changes.

The following is a general guideline in choosing the security mode for your NWA. • Use WPA or WPA2 security if you have WPA/WPA2-aware wireless clients and a RADIUS server. WPA has user authentication and improved data encryption over WEP. • Use WPA-PSK or WPA2-PSK if you have WPA/WPA2-aware wireless clients but no RADIUS server. • If you don't have WPA/WPA2-aware wireless clients, then use WEP key encrypting. A higher bit key offers better security. You can manually enter 64bit, 128-bit or 152-bit WEP keys. More information on Wireless Security can be found in Appendix A on page 303.

10.3
Technical Reference
This section provides technical background information on the topics discussed in
this chapter.
The following is a general guideline in choosing the security mode for your NWA.
Use WPA or WPA2 security if you have WPA/WPA2-aware wireless clients and a
RADIUS server. WPA has user authentication and improved data encryption
over WEP.
Use WPA-PSK or WPA2-PSK if you have WPA/WPA2-aware wireless clients but
no RADIUS server.
If you don’t have WPA/WPA2-aware wireless clients, then use WEP key
encrypting. A higher bit key offers better security. You can manually enter 64-
bit, 128-bit or 152-bit WEP keys.
More information on Wireless Security can be found in
Appendix A on page 303
.
