I don't remember where I found that information, but here is the
relevant section from the ipw3945 driver documentation.
-----------------------------------------------------------------------
To configure the power level on the Intel PRO/Wireless 3945ABG Network
Connection driver for Linux, you must use the iwpriv set_power command:
Setting the power management on and off via 'iwconfig power' is not
currently supported by the driver.
iwpriv set_power 1-5 Set the power level as specified.
iwpriv set_power 7 Set power level to default BATTERY level.
Setting the power level to any other value (0, 6, >7) will result in setting
the device into AC mode with Power Management disabled.
If you explicitly set AC mode, the radio will always be on, however because
you have set a specific mode, it will still show as 'Power Management: on'
via wireless tools.
You can view the current power level setting via:
iwpriv get_power
It will return the current period or timeout that is configured as a string
in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
time after packet processing), yyyy is the period to sleep (amount of time
to wait before powering the radio and querying the access point for buffered
packets), and z is the 'power level'.
If the adapter was configured to a mode outside the range 1-7, the value
6 (AC) will be displayed followed by the text OFF to indicate a value
outside of the Power Management range was specified.
If the adapter is configured to any mode 1-7 then the wireless tool will
report 'Power Management: on'. If the mode is set to 0 or > 7, the
wireless tools will report 'Power Management: off'.
