Figure 39. WPA/WPA2 Enterprise (RADIUS) Security Mode Settings
1. Configure the following settings:
WPA Versions
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 which provides the best security per the IEEE 802.11i
standard.
Both - If you have a mix of clients, some of which support WPA2 and
others which support only the original WPA, select Both. This lets both
WPA and WPA2 client stations associate and authenticate, but uses
the more robust WPA2 for clients who support it. This WPA
configuration allows more interoperability, at the expense of some
security.
Enable pre-authentication
If for WPA Versions you select WPA2 or Both, you can enable pre-
authentication for WPA2 clients.
Click Enable pre-authentication if you want WPA2 wireless clients to
send pre-authentication packet. The pre-authentication information will
be relayed from the access point the client is currently using to the
target access point. Enabling this feature can help speed up
authentication for roaming clients who connect to multiple access
points.
This option does not apply if you selected WPA for WPA Versions
because the original WPA does not support this feature.
