ONFIGURATION
WPA/WPA2/Mixed WPA WPA2 +Radius
PSK2+RADIUS features using of a RADIUS server with the
pre-shared key authentication method. (This should only be used
when a RADIUS server is connected to the Router).
WPA provides a higher level of security, provided by its longer key and
dynamic changes made to the key over time. 3Com recommends that
you use WPA with any clients which support it.
If you enable encryption on the Router, you must reconfigure your
wireless PCs to use exactly the same Encryption Type and Keys
otherwise the devices will not understand each other.
The encryption methods used by the Router secure data transmitted
through wireless communications between the Router and its wireless
clients. Enabling encryption has no security effect on data transmitted
through wired (Ethernet) connections or through your connections to
the Internet.
Configuring
WPA/WPA2
Encryption
You can choose to use a RADIUS server to authenticate clients, or you
can specify a pre-shared key.
The pre-shared key is used to start the dialog between the Router and
the client. During this dialog, a new key is agreed, making it more
difficult to eavesdrop on wireless networks encrypted using WPA, than
those encrypted using WEP.
To use a RADIUS Server to authenticate each user before they join
the network, refer to “Using the Radius Server” on page 55 .
To set up the pre-shared key, refer to “Using Pre-Shared
Passphrase” . on page 56 .
