Note:
You must enable data encryption through the web or CLI in order to enable all
types of encryption (WEP, TKIP, or AES) in the access point.
The access point can simultaneously support clients using various different security
mechanisms. The configuration for these security combinations are outlined in the
following table. Note that MAC address authentication can be configured
independently to work with all security mechanisms and is indicated separately in
the table. Required RADIUS server support is also listed.
WPA2 with 802.1X Requires WPA-enabled system
and network card driver (native
support provided in Windows
XP)
• Provides the strongest security in WPA2-only
mode
• Provides robust security in mixed mode for WPA
and WPA2 clients
• Offers fast roaming for time-sensitive client
applications
• Requires configured RADIUS server
• 802.1X EAP type may require management of
digital certificates for clients and server
• Clients may require hardware upgrade to be WPA2
compliant
WPA2 PSK Mode Requires WPA-enabled system
and network card driver (native
support provided in Windows
XP)
• Provides robust security in small networks
• Requires manual management of pre-shared key
• Clients may require hardware upgrade to be WPA2
compliant
