Turning Your Client Adapter Radio On or Off

Your client adapter radio can be turned on or off. Turning the radio off prevents the adapter from
transmitting RF energy. You might want to turn off the client adapter radio when you are not transmitting
data and want to conserve battery power or when you are using a laptop on an airplane and want to
prevent the adapter's transmissions from potentially interfering with electronic devices.
If the radio is not turned off, it periodically sends out inquiry packets even if it is not associated to an
access point, as required by the 802.11 specification. Therefore, it is important to turn it off around
devices that are susceptible to RF interference.

Client Utility Advanced RF Settings Screen Parameters (continued)
Description
Selecting this check box enables the client adapter to assume the legal
transmit power level and channel set of the access point to which it is
associated. This parameter is available only in computer to access point
(infrastructure) mode and is designed for users who travel between countries
because it allows the adapter to be used in different regulatory domains.
Default: Deselected
Note When World Mode is enabled, only the transmit power levels
supported by the country of operation's regulatory agency are
available.
If your network's access points are set to communicate with either
WEP-enabled or WEP-disabled clients (that is, if the Use of Data Encryption
by Stations parameter on the AP Radio Data Encryption screen is set to
Optional), you must select this check box, even if your client adapter is not
using WEP. If this setting is not enabled, your client adapter cannot establish
a connection with the access point.
Default: Deselected
For security reasons, Cisco recommends that both WEP-enabled
Note
and WEP-disabled clients not be allowed in the same cell because
broadcast packets will be sent unencrypted, even to clients
running WEP.
Your client adapter is not associated while the radio is off.
