Cisco AP541N Dual-band Single-radio Access Point Quick Start Guide

Select the types of client stations you want to support:

•

WPA. If all client stations on the network support the 
original WPA but none support the newer WPA2, then 
select WPA.

•

WPA2. If all client stations on the network support 
WPA2, we suggest using WPA2, as it provides the 
best security by supporting the IEEE 802.11i standard.

•

WPA and WPA2. If you have a mix of clients, some of 
which support WPA2 and others which support only 
the original WPA, select both WPA and WPA2. This lets 
both WPA and WPA2 client stations associate and 
authenticate, but uses the more robust WPA2 for 
clients that support it. This WPA configuration allows 
more interoperability, at the expense of some security. 

If in WPA Versions you selected only WPA2 or both WPA and 
WPA2, you can enable pre-authentication for WPA2 clients.

Click Enable pre-authentication if you want WPA2 wireless 
clients to send a pre-authentication packet. The pre-
authentication information is relayed from the access point 
the client is using to the target access point. Enabling this 
feature can speed up authentication for roaming clients that 
connect to multiple access point

This option does not apply if you selected only WPA for WPA 
Versions because WPA does not support this feature.
