NWA-3160 Series User’s Guide

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.

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).
