txpower - Set Transmit Power

Set the transmit power for data packets. Bare numbers are interpreted as values in dBm. If the number is followed by mW, the value is interpreted in milliwatts. The value can also be auto for automatic power control and off for disabling the radio transmission.

Example:The following command sets all data packets to transmit at either 30 dBm or the maximum allowed in the current regulatory domain:

myprompt# iwconfig ath0 txpower 30
