freq/channel - RF Frequency or Channel

Set the frequency or channel of the device to the given value. Values below 1000 are interpreted as channel numbers. Values above 1000 are interpreted as frequency measured in Hz. For frequency values, the suffix k, M, or G can be appended to the value to specify kilohertz, Megahertz, and Gigahertz, so that 2.412G, 2412M, and 2412000000 refer to the same frequency. Setting the channel to a specific value will override the private mode control described in Section .

Example:The following command sets the operating frequency to 5.2GHz:

myprompt# iwconfig ath0 freq 5.2G

Either of the following commands set device to operate on channel 11:

myprompt# iwconfig ath0 freq 11
myprompt# iwconfig ath0 channel 11
