Subject: Setting my WiFi adhoc connection in power save mode

Hello,

I am trying to set power save mode in my Intel 3945ABG wireless card
under Ubuntu 10.10 - Maverick Meerkat and iwl3945 driver.

I need to set power save mode. In order to do so I tried to change
period and timeout options of iwconfig command so that beacon period
and ATIM window are changed.

For instance
:~$ sudo iwconfig wlan0 power period 2
    Error for wireless request "Set Power Management" (8B2C):
    SET failed on device wlan0 ; Invalid argument.

As you can see I get an error. Is it because it is not supported in my
card? Is there any way to set beacon interval and ATIM window
parameters?

Many thanks in advance,
Jorge
