disk space when not needed.
Minimum Connection Time
(sec)
The minimum connection time the radio stays connected to the current access point
before roaming begins. Default 10 seconds, range is 5 to 25.
Roam RISSI Difference (dBm) The minimum signal strength difference between APs before the radio roams. De-
fault 5 dBm, range is 5 to 25.
Background Scan
Signal Level (dBm) The minimum signal strength an access point signal must have to be considered for
roaming. Default -65 dBm, range is -80 to -55.
Probe Request Interval (sec) The interval between roam probes. Default 5 seconds, range is 5 to 60.
CCX Control
Note: For CCX to be enabled, two settings must be enabled:
• CCX must be enabled (checked) on this screen.
• Enable Atheros Connection Settings must be enabled (checked) on the Connection (page 6-5) tab.
If both settings are not enabled, the WLAN radio does not identify itself as CCX V4 compatible when associating to
an access point.
CCX Use CCX (Cisco Client Extensions) for faster roaming. Default is enabled.
CCKM Use CCKM (Cisco Centralized Key Management) for faster roaming. Default is en-
abled.
Power Save Set the power save level. Options are Off (default) and Auto-PSM.
Band Selection Select the bands to use. Options are: A, BG, G, ABG (default).
DatRate Selection To limit data rates, check the Limit DataRate checkbox. If checked, select the desired rate (MCS0
to MCS15). MCS0 (Modulation and Coding Scheme) 0 is slowest, MCS15 is fastest but subject
to more errors. Default is disabled.
