AWUS036NH TX Power

[Scamentology]

First - If you break your card??? I am not going to lose any sleep over it.

I was able to get the TX Power of my awuso36nh card all the way up to 33 working with injection. Here is how I did it.
One warning. I am doing this on Ubuntu but it shouldn't be too much different.

I followed Joker5bb great tutorial (This was really helpful). except...
http://hacking-library.com/forum/vie...284&p=550#p550

I was having issues so instead of adding an entire country code (XX) to the db.txt file I just changed the US channels max TX to 33.

It went from this

country US:
        (2402 - 2472 @ 40), (3, 27)
        (5170 - 5250 @ 40), (3, 17)
        (5250 - 5330 @ 40), (3, 20), DFS
        (5490 - 5600 @ 40), (3, 20), DFS
        (5650 - 5710 @ 40), (3, 20), DFS
        (5735 - 5835 @ 40), (3, 30)

to this

country US:
        (2402 - 2472 @ 40), (3, 33)
        (5170 - 5250 @ 40), (3, 17)
        (5250 - 5330 @ 40), (3, 20), DFS
        (5490 - 5600 @ 40), (3, 20), DFS
        (5650 - 5710 @ 40), (3, 20), DFS
        (5735 - 5835 @ 40), (3, 30)

I did not mess around with the other frequencies but you see how it works.

make sure your compat-wireless drivers are up to date.

You may want to get the more updated packages from the one in this tutorial

http://wireless.kernel.org/download/wireless-regdb/wireless-regdb-2011.04.28.tar.bz2
http://wireless.kernel.org/download/crda/crda-1.1.2.tar.bz2

Make sure you 'iw reg set US' if thats the section you changed.

Do this at your own risk.

Here is the output

I have to say, with a good antenna and a powered USB hub, this is the best wireless card I have ever owned.

thanks!
from now on will use more often my second wifi-card!!!!

hi, scamentology
ummm. I sang victory too soon !!!
Assuming that you want to try on BT5-r1 (assuming responsibilities on my tests)
what are the steps to do?
reading the "links ".... I know little (it is normal for my brain )
BT5-in-the drivers for my r1 awuso36NH alpha (present) are fine and should be changed?
-the "iw package" default is good?
in my BT5-r1 default seems to operate at 30dB:
root @ bt: ~ # iw reg Sept. BO
root @ bt: ~ # iwconfig wlan1 txpower 30
root @ bt: ~ # airmon-ng start wlan1


Found 1 processes Could That causes trouble.
If airodump-ng, aireplay-ng-ng stops working or airtun after
a short period of time, You May want to kill (some of) them!

PID Name
675 dhclient3


Interface Chipset Driver

wlan1 Ralink RT2870/3070 rt2800usb - [phy3]
(monitor mode enabled on mon0)

root @ bt: ~ # iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wlan1 IEEE 802.11bgn ESSID: off / any
Mode: Managed Access Point: Not-Associated Tx-Power = 30 dBm
Long retry limit: 7 RTS thr: off Fragment thr: off
Encryption key: off
Power Management: on

mon0 IEEE 802.11bgn Mode: Monitor Frequency: 2.437 GHz Tx-Power = 30 dBm
Long retry limit: 7 RTS thr: off Fragment thr: off
Power Management: on
I am curious to test whether "between how it works now and how the work you've done there is not much difference"
from what little I understand (the default-BT5) 30dB In The Same: Worked alfa36H order to RESPECT Alpha 36NH.
sorry if I have dwelt thanks in advance!

Vivek did a pretty awesome video on this in his "wireless lan security megaprimer".
You should check that out too.

I will never cease to thank you !!!!

I saw that vid. everything that guy does is awesome.

@zimmaro Did you get it working? The only reason to change anything is to get the TX Power up to 2 watts (I HAVE NOT verified if it is actually putting out 2w).

TX Power of 33 should give you 1.995w according to the converter @ http://www.moonblinkwifi.com/dbm_to_watt_conversion.cfm

There was someone around here that was going to use an oscilloscope on it. I am curious to know the outcome.

hi, scamentology
I could not! (it is normal for my life ....) eheheh!
I tried to replace the file "db.txt" in usr / src / linux (or linux-source-2.6.39.4) / net / wireless / db.txt
but do not work!
1) I'm "testing" bt5r1 (vbox)
2) I'm using "default-drivers" (Worked-fine in "" "sniff" ") & (crash" "normaly-use" ") max power 30db
3) I'd like to know the steps to be done starting from "zero-point" [which is equal to my highest point to my brain-receptive !!!]
thanks for your interesting!
bye

hi,
I've made it !!!
in my little test (vbox)
the card is reborn!
-at (32db) is very-good airodumping
-work on the injection (aireplay-ng -- test mon0) but in the "session-work" I do not think!
-sometimes my card goes down!
now I wanted to ask:
is required to use the compat-drivers?
I have them installed and then I "installed and built" the two packages (the link)
I hope I have done right! (at least to me seems to work)
my little test have finished!!!thks

I have my 036NH running at full 2mw. There is a tutorial around here somewhere that I followed.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=35 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          
mon0      IEEE 802.11bgn  Mode:Monitor  Frequency:2.427 GHz  Tx-Power=35 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

I do not know if you need the compat wireless drivers but... thats the process I went through, so thats how I wrote it up.
I don't know what you mean "session-work"?

It works in Backtrack 5r1. My test was done on a live dvd and if you reload the drivers you wont need to reboot.

Another warning. If you turn this up in the states with a gain antenna above 6 you will be breaking the law. I wont be running my card at 2 watts because I don't need it. I just don't like restrictions when it comes to my hobbies and it has no effect on others, I am sure others feel the same.

Have fun.
