AWUS036NH TX Power

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

Code:

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

Code:

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

Code:

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

Code:

# ifconfig wlan1 down # iw reg set US # iwconfig wlan1 txpower 32 # ifconfig wlan1 up # airmon-ng start wlan1 Interface Chipset Driver wlan1 Ralink RT2870/3070 rt2800usb - [phy2] (monitor mode enabled on mon0) # iwconfig wlan1 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=32 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on mon0 IEEE 802.11bgn Mode:Monitor Tx-Power=32 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:on # airmon-ng Interface Chipset Driver wlan1 Ralink RT2870/3070 rt2800usb - [phy1] mon0 Ralink RT2870/3070 rt2800usb - [phy1] # aireplay-ng --test mon0 00:00:23 Trying broadcast probe requests... 00:00:23 Injection is working! 00:00:24 Found 4 APs

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!!!!

Re: AWUS036NH TX Power

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.

@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.

Re: AWUS036NH TX Power

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

Re: AWUS036NH TX Power

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

Re: AWUS036NH TX Power

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

Code:

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

Re: AWUS036NH TX Power

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.
