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 card 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: You can enable the parameter when you want to fast roaming to
the network nearby without intercepting the wireless connection, especially the adapter is
applied to the multimedia application or a voice call. The adapter 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 adapter temporarily, click this
button. To turn on the radio, click this button again.
Radio On: Indicate to turn on radio.
Radio Off: Indicate to turn off radio.
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), and 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 and 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
