Enabling or Disabling Your Client Adapter’s Radio
Your client adapter’s radio can be enabled or disabled. Disabling the radio prevents the adapter from
transmitting RF energy. You might want to disable the client adapter’s radio in the following situations:
•
You are not transmitting data and want to conserve battery power.
•
You are using a laptop on an airplane and want to prevent the adapter’s transmissions from
potentially interfering with the operation of certain devices.
When the radio is enabled, it periodically sends out probes even if it is not associated to an access point
(in infrastructure mode) or another client (in ad hoc mode), as required by the 802.11 specification.
Therefore, it is important to disable it around devices that are susceptible to RF interference.
Note
Your client adapter is not associated while its radio is disabled.
