ath5k simply doesn't support that command at this time. I'm not sure what (if any) plans there are for that in the near future. Bob? Does the latest stable kernel(2.6.35-rc5) or compat-wireless(2.6.35-rc4.tar.bz2) support power management for ath5k? Going by the code it seems they don't have it. Could somebody confirm, please? No, it does not support it yet. No one is actively working on it yet but it is definitely something worth doing... I get this on the 3.0.X Kernel, could I get one version of power setting done: iwconfig wlan0 power off? The reason is I can't even use my wlan0 because of this error.

There must be something else wrong. FWIW I am currently dusting off some patches to implement PS mode. |
You will get an error when trying to adjust any of the "power" parameters using iwconfig. For example: # iwconfig wlan0 power on Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan0 ; Operation not permitted. Using Atheros AR2425 chip
