Dynamic WEP Key Length When 2.4GHz, 802.11b wireless clients are
using certificate-based authentication (EAP-TLS or EAP-TTLS), dynamic
WEP keys are automatically generated. Select the length of the Dynamic
Key (64 or 128-bit) from the drop-down menu.
Key Renewal Timeout If you are using dynamic WEP keys (available only
for EAP-TLS or EAP-TTLS authentication), enter the number of seconds
that will elapse before the Dynamic Key automatically changes. The default
is 300 seconds.
Port Inactivity Timeout After the wireless client has been authenticated, the
Router monitors activity on the port being used. In the Port Inactivity
Timeout field, enter the number of seconds the port can be inactive before
the client automatically forced to reauthenticate. The default is 600 seconds.
Port Connectivity Timeout After the Router requests the identity of a wire-
less client, the client must respond with an identity message within a cer-
tain length of time. In the Port Connectivity Timeout field, enter the number
of seconds the client has to respond within before the connection is termi-
nated. The default is 300 seconds.
