Hello everyone, recently i got a awus036h because i read a lot of good stuff about on this website.
The problem isn't the tx power i'v put that on 30dbm so no probs But i have really slow connection when i connect to different networks.
Now i noticed that the power management of the adapter is off so how is it possible to turn it on?
When i do
 iwconfig wlan0 power on
i get the following error:

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

I've been breaking my head over it just seems impossible to turn it on?

Can someone please help me would be nice if there was a solution for my debian squeeze machines as well.
