Parameter Description
Enable TCP Window Size The TCP Window is the amount of data a sender can send on a
particular connection before it gets an acknowledgment back from
the receiver that it has gotten some of it. When the Router or AP
the adaptor is connecting to have set up the TCP Window, you can
enable the parameter to meet the data size for the Router or AP
connection. The larger TCP Window the better performance.
Fast Roaming at -70dBm When you want to fast roaming to the network nearby without
intercepting the wireless connection especially the adaptor is
applied to the multimedia application or a voice call, you can
enable the parameter. The adaptor will fast roaming to the near
network when the receive sensitivity (signal strength) is lower to
the value you have set up.
Turn Off RF Button If you want to turn off the radio of the adaptor temporarily, click this
button. To turn on the radio, click this button again.
CCX 2.0 CCX 2.0 (Cisco Compatible Extensions) is developed by Cisco for
the radio monitoring and fast roaming.
LEAP Turn on CCKM During normal operation, LEAP-enabled client devices mutually
authenticate with a new access point by performing a complete
LEAP authentication, including communication with the main
RADIUS server.
When you configure your wireless LAN for fast re-association,
however, LEAP-enabled client devices roam from one access
point to another without involving the main server. Using Cisco
Centralized Key Management (CCKM), an access point configured
to provide Wireless Domain Services (WDS) takes the place of the
RADIUS server and authenticates the client so quickly that there is
no perceptible delay in voice or other time-sensitive applications.
Enable Radio Measurement When this parameter is enabled, the Cisco AP can run the radio
monitoring through the associated CCX-compliant clients to
continuously monitor the WLAN radio environment and discover
any new APs that are transmitting beacons.
Non-Serving Channel
Measurements
The Cisco AP can perform monitoring measurements through the
CCX-compliant clients on the non-serving channels when this
parameter is enabled.
Limit xxx milliseconds (0-2000)
It limits the channel measurement time. The default value is 250
milliseconds.
