tweeking the Alfa

[>script_kiddie]

What's up community,

So I was going through the Wifi-Megaprimer series from Vivek / securitytube.net - good stuff. Anyways, there was a section on "Alfa Card kung-fu" which basically talked about changing tx power and things of that sort by altering the Country Code for the regulatory domain.

What I'm wondering, is if there is any way to change the "disabled" frequencies to be "enabled". I'm sure it's based off the Country Code as well so i'm thinking there is no way to do this???

That's what brings me to asking my fellow nerds. *My screen shots are to big and i don't really have time to mess with em at the moment*

OS: Kali Linux 1.0.7

NIC: Dual Band Alfa Card 802.11 a/b/g/n - AWUS051NH - Ralink chipset - monitor works, tested with Airodump - Injection works, tested with aireplay-ng -9 -b xx:xx:xx:xx:xx:xx mon0 --ignore-negative-one

-9 = test

-b = BSSID

--ignore-negative-one = !#$%@#$@##$@#%$!#$@%@#$@

Tools:

Kali

Alfa card

Wireshark - for verification

Aircrack suite

test AP

ifconfig wlan* down #replace the wildcard with your adapters number

iw reg set BO # BO is the country code, the codes tell your NIC what rules to follow based on the countries FCC equivalent. Originally mine was set to GB - Great Britain i believe.

iwconfig wlan* txpower 30 # in dBm (Decibel mW ), my card was at 27 dBm (.5W) by default - this changed it 30 dBm (1W) - I'm pretty sure the FCC wont like this to much, testing purposes though :->

ifconfig wlan* up # blah blah blah anyways... after unplugging the Alfa from the comp and going to lunch, it reset itself back to default

plug a interface in, turn it on if you need to and run the command: iw list #shows details about the wireless cards, you can scroll down and see the freq/channel. That list is what the question revolves around.

side notes:

*yes, i have Googled and researched for half of today to no avail*

* doing this has made my card temporarily act a bit funny when running Airodump-ng - random stops, slow channel scanning, no displayed results*

*the card seems to change back after unplugging it* - not to sure if there is a comit or anything that I missed but this is just testing anyways so.*

* You may or may not have to take the interface down to make the change, a few times while trying this i didn't do "ifconfig wlan down" but "iw list" showed the changes take effect while the card was up the whole time*

Thanks in advance guys/girls, take care
