Hi all, here's a question, maybe for anyone who understands programming the awus036H. (sorry, not N as i typo-ed in the thread title)
With the rtl8187 driver from kernel 18.104.22.168 and an awus036h (genuine) - the 1W version, I am finding that iwconfig txpower has no effect. I suspected this was the case, so I ran the folliwing proving test:
I ran a monitor with another card, (using airodump-ng)
I then ran a ping flood (ping -f) on the router to get a lot of packets going and monitored the STATION PWR being reported by airodump-ng
As I moved the awus towards and away from the monitoring card, I see major changes in the PWR levels being reported. this proves the number reflect the strength of signal being received.
Then I placed the awus as far away from the internal card as the usb cable will allow, and the PWR reported settles at around -30
Now I open another terminal and run iwconfig wlan1 txpower 0,1,2.. etc up to 27. There is no change whatsoever in the PWR levels being reported by airodump-ng.
I can only conclude that things are as I suspected, that the txpower setting is having no effect.
Now, I know most people want to fry everything by turning UP the power on the card, the net is full of posts about overriding the regional restrictions and all that, but I want to turn the power DOWN to the minimum necessary for communication with the AP.
Any words of wisdom are most welcome
EDIT: I should add that after running iwconfig txpower for each setting, iwconfig or iwlist subsequently reports that the power has changed, but the observations of the test above show otherwise.
