[SOLVED] BCM4322 and power management

I've got a BCM4322 wifi card (according to lspci) and I'm using the b43-firmware from AUR.
It seems like the b43 driver doesn't support power management; iwconfig says:

Power Management:off

and if I try to use

iwconfig wlan0 power on

I get:

Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Operation not supported.

Is there any other way to reduce power consumption of this card or enable power management?

Thanks in advance.

Re: [SOLVED] BCM4322 and power management

have you tried:

sudo iwconfig wlan0 power on

?

I got your error,

Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Operation not supported.

when I tried the above command without sudo.

Thanks for your response msb!

EDIT: Noticing my card being supported by it, I switched to broadcom-wl driver now and don't get any drop-outs anymore as well as having power management supported.

Solved.
