Hello all,

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

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 non-default values for beacon interval and ATIM window?

Many thanks in advance,
Jorge.
