- The Ultimate Guide to Upping Tx-Power in Kali Linux 2.0
- BY SINGULARITY 02/03/2016 12:47 AM
- Yes, I understand some people may consider this a repost. However, I have been searching for this answer for 3 weeks and after reading numerous reddit post, Kali Forums post and Null byte post I finally have gotten it to work for me. I would like to compile and share this information with you guys.
- Also, this guide addresses the
- /bin/sh: 1: pkg-config: not found
- /bin/sh: 1: pkg-config: not found
- /bin/sh: 1: pkg-config: not found
- /bin/sh: 1: pkg-config: not found
- Makefile:76: Cannot find development files for any supported version of libnl. Stop.
- Note there is one more asterisk, but the website formatting messes it up
- Error, If your only looking for a fix to that, scroll to the Troubleshooting area.
- WAIT
- Removing all restrictions is illegal in the United States. This tutorial is only for educational reasons, and if you choose to apply it and break the law, then that is your choice and not mine.
- Lets begin.
- Prerequisites (Requirements)
- Luckily, there are not many and if your looking at this post, you probably have them.
- Some form of Linux (I will be using Kali)
- An adapter able to amp up the TX Power, (check this post out)
- Basic Linux Skills
- Run 'sudo apt-get update' before trying guide.
- Step 1Dependencies (Required Files)
- To begin, you must first install the required dependencies to your Linux Distro.
- Simply open up a terminal, copy and paste this command:
- apt-get install libnl-3-dev libgcrypt11-dev libnl-genl-3-dev
- I already have it installed, so it should look somewhat similar to what the pic says.
- Note: If you are not root then you need to add 'sudo' before apt-get Ex.: sudo apt-get install .... this will ask you for your password. Simply type it in (it will not pop up) and press enter.
- Step 2Download and Extract Required Files
- Download
- We need to download two files, CRDA and wireless-regdb . (Click the file names to navigate to the websites to download them.) Be sure to download the <filename>.tar.xz version of the wireless-regdb file. Ensure you download the latest. For CRDA select CRDA-3.18 (Remember a new version could be out) and for wireless-regdb scroll to the very bottom and select the newest.
- Move these to your desktop.
- Extract
- Open a terminal, navigate to your desktop and run these commands:
- unxz crda-3.18.tar.xz
- unxz wireless-regdb-2015.12.14.tar.xz
- Copy & Paste may not work, be sure to change the filename to what you downloaded
- Then Run:
- tar -xf crda-3.18.tar
- tar -xf wireless-regdb-2015.12.14.tar
- Same as previous note
- Now you should have the two files fully extracted on your desktop. Delete the old tar files.
- Step 3Editing Wireless-Regdb
- Change Directory to the wireless-regdb folder,
- cd ~/Desktop/wireless-regdb-2015.12.14
- Then type:
- ls
- You should see a file named 'db.txt' We want to edit that file.
- sudo nano db.txt
- If you are not root, you must use sudo are your changes will not be saved
- The first entry we see 'country 00' That is the world domain. This is what your card is first set to.
- We are going to edit Bolivia. In the db file, it is known as BO. Scroll down till you see BO.
- Here you can see BO's tx power is maxed at '20.' You can push this as far as your card can go, but we are going with 30, which is usually a safe number.
- Change the 20 to 30 and hit CTRL-X, Y, and Enter.
- Running an antenna with this power can possibly be a health hazard. Easily avoid this by not placing the antenna directly on or in you.
- Step 4Update Old CRDA with New CRDA.
- Inside the wireless-regdb-2015.12.14 folder, type the command:
- sudo make
- This creates new files inside the folder.
- Now, we change to the soon-to-be old CRDA folder.
- cd /lib/crda
- List the files
- ls
- Now change the 'regulatory.bin' file to 'regulatoryOLD.bin'
- sudo mv regulatory.bin regulatoryOLD.bin
- Now change back to the wireless-regdb-2015.12.14 folder on your desktop.
- cd ~/Desktop/wireless-regdb-2015.12.14
- Copy new regulatory.bin to crda folder
- sudo cp regulatory.bin /lib/crda
- Now, change back to /lib/crda and type: ls
- Ensure it contains 'regulatory.bin'
- Step 5Copying PEM Files to Validate
- Change to ~/Desktop/wireless-regdb-2015.12.14
- Type this command:
- sudo cp (asterisk).pem ~/Desktop/crda-3.18/pubkeys
- I cant type the asterisk due to the website formatting This is what it is suppose to be
- Then this:
- cd /lib/crda/pubkeys
- sudo cp benh@debian.org.key.pub.pem ~/Desktop/crda-3.18/pubkeys
- These commands copy .pem files used to validate the regulatory.bin
- Step 6Editing Makefile to Fit Kali 2.0
- cd ~/Desktop/crda-3.18
- sudo nano Makefile
- Change the 3rd line from: REGBIN?=/usr/lib/crda/regulatory.bin to REGBIN?=/lib/crda/regulatory.bin
- See the difference? Simply remove the '/usr' from the path.
- Step 7Installing
- Be sure you are in the crda directory. cd ~/Desktop/crda-3.18
- Run:
- sudo make
- sudo make install
- If you have an issue here, look in the troubleshooting section.
- <PIC>
- If our screens match, your good.
- Step 8Amping TXPower
- Reboot your pc and type in these commands:
- sudo ifconfig <wireless adapter> down
- Repeat this step for all wifi adapters you have
- sudo iw reg set BO
- sudo ifconfig <wireless adapter> up
- Repeat this step for all wifi adapters you have
- sudo iwconfig <your adapter, in my case wlan1> txpower 30
- Now type: sudo iwconfig
- and you should see your adapter with TXPower: 30
- <PICS>
- Finished
- Awesome! If everything worked for you, good job! If not, look at the troubleshooting area down below. Please leave a comment and kudos if I helped you :)
- ------------------------------------------------------------------------------
- Step 9Troubleshooting
- I will add to this part if any other problems arise
- Cannot Find Development Files for Any Supported Version of Libnl. Stop
- Arises: In the final step when typing: make and make install in the new crda directory.
- Full Error:
- Also, this guide addresses the
- /bin/sh: 1: pkg-config: not found
- /bin/sh: 1: pkg-config: not found
- /bin/sh: 1: pkg-config: not found
- /bin/sh: 1: pkg-config: not found
- Makefile:76: Cannot find development files for any supported version of libnl. Stop.
- Note there is one more asterisk, but the website formatting messes it up
- Solution:
- Download Synaptic and run apt-get update
- sudo apt-get update
- sudo apt-get install synaptic
- Run synaptic:
- sudo synaptic
- Select Search
- Type: universe
- Under all select: universe
- Scroll to the bottom and select all packages with 'lib' in it.
- <pic>
- Hit apply and wait, process generally takes a bit.
- Reboot and retry step.
- TX Power Not Changing/Iw Reg Not Changing.
- Arises: When your adapters location has been hard coded.
- Solution:
- Type:
- sudo iw reg get
- What ever country code pops up go back into the db.txt and change the txpower max similar to how it was done to BO (Bolivia)

- Well, the US's laws say your not allowed to exceed 20 dBm (20 Tx Power). My guess (which could be completely wrong) is that these laws are in place to keep networks from overpowering each other. Mostly for malicious reasons, which is why most people are looking to up their TX Power. It doesn't stop many people from doing it though. I imagine it would be pretty hard to get caught unless you start doing it in public areas or try to crack the wrong people. Ill look more into it later.
- Update:
- For anyone curious, I also thought it was notable that it can be a health hazard having your TX Power so high for a lengthy amount of time close to your body. (Just dont be on top of it basically.)

- Hi people, I cannot manage to increase TX Power to 30
- I have done all the steps succesfully but when I do "iw reg set BO" and bring the interface up the change is not done.
- When I do "iw reg get" I am still in the global one, so I went to the troubleshooting and saw that I should change the db.txt again. Here is my doubt after changing it, do I have to generate a new .bin, update the CRDA and copy the PEMS? Or just changing the db.txt should work?
- And when changing the db.txt in the global part, do I only need to change the 2402-2472 to 30, or should I change everything to 30?
- Many thanks buddies!

- Sorry guys I just figured it out, just remake the whole process from scratch and just in case, I edited both BO and 00 to 30. In any case I dont know why but now I was able to switch to BO what I couldnt before(stuck in 00). After switchin to BO I automatically switched to 30 so I didnt have to run the "iwconfig wlan1 txpower 30" command.
- So I guess it's all cool now!

- Very good, thank you for sharing! Well, certainly worked like a charm on my very 'old school' NetGear WG111v3 (Realtek RTL8187B chipset), which I currently have cranked up to 33dBm (originally set to 20dBm).
- Unfortunately, cranking up the Tx-P by +13dBm made very little difference to AP signal strengths, beacon nos. or deauth/injection effectiveness. But that may be because this old bugger (the dongle, not me) doesn't sport an external aerial.
- I'm curious, though, how high could we (theoretically, of course) crank the Tx-P on these things? Would it make a meaningful difference? Has anyone gone beyond 33dBm? Is there a built-in hardware limit? If anyone knows or has mucked around with this I'd be interested to hear from you.

- Hey Harry, if everything 'worked' in making/installing the new CRDA dB and you reg set the TX Power to BO (check with iw reg get) but still find yourself stuck on 20dBM, then try the process again, this time ensuring you increase the TX to, say, 30dBm, for (1) the global region (top of the list) and (2) your country region. I found that my WiFi reg would be set back to either global or AU (I'm Aussie) by some SYS settings and other apps so I just went nuts and replaced the 00 (global) and AU (my country) with 33dBm. I also replaced like BO with 35dBm, UK with 36, US with 37 etc etc. So I now have a virtual TX Power 'dial' which I can turn up and down with 'is reg set XX', depending on how much cancer I want to give my cat. Also note that some cheap China WiFi dongles just don't exceed 20dBm no matter what. 2/3 of my WiFi cards work with this trick but one super cheap Chinese one I've got won't cooperate. Start with ensuring TX is 30 for 00 global and your home region and see if that works first. Good luck mate!

- Hey Harry,
- as stupid as it sounds, did you put down your <wlan0> interface with ifconfig <wlan0> down? :)
- I had all the errors above with libnl (install pkg-config ) and "-Werror" (removed it from the Makefile and entered "make clean" "make" and "make install" again).
- Everything worked, except i could not change the txpower . Even the "iw reg get" showed Bolivia (BO) with the correct values i entered in the db.txt file.
- The simple solution was to bring down the interface first before changing the tx power (which makes sense if you think about it :) ).

- Hary Pale told that solved his problem by adding
- -Wno-error -Wno-unused-const-variable
- in the Makefile. Where exactly he add it, in Makefile ?
- My problem is that after "make" in crda-3.18 directory i receive (three last lines)
- M2Crypto.RSA.RSAError: no start line
- Makefile:113: recipe for target 'keys-gcrypt.c' failed
- make: ** keys-gcrypt.c Error 1
- Any help ??

- I have the same error and found a link to this:
- https://unix.stackexchange.com/questions/413774/crda-make-error
- yet I have no idea what build requirements solved it. Maybe someone can test and clarify?

- Had the same error here. I'm pretty sure I used this guide successfully in 2017, but for the life of me it's not working on Kali 2018.1
- Then I found an article, which really helped: miloserdov.org/?p=337
- Long story short, run these commands (after updating apt-get and installing all the packages from this guide):
- git clone git://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git
- cd wireless-regdb/
- gedit db.txt
- Modify country BO to 30dbi instead of 20, then save
- sudo make
- sudo mv /lib/crda/regulatory.bin /lib/crda/regulatory.bin.bak (make backup copy of old regulations)
- sudo cp regulatory.bin /lib/crda/regulatory.bin
- sudo cp $USER.key.pub.pem /lib/crda/pubkeys/ (substitute your username to $USER, e.g. root.key.pub.pem)
- Done!
- Now go with the usual commands:
- sudo iw reg set BO
- sudo iwconfig <your adapter, in my case wlan1> down
- sudo iwconfig <your adapter> txpower 30
- sudo iwconfig <your adapter, in my case wlan1> up
- There you go. Enjoy!

- And something very important !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- Limits of each country is something complete different from real safe limits. According to many and very serious scientists, the safe for health limit is ZERO microWatts per m2 (per square meters). But because most people cannot leave without wifi, scientists put a limit to 0.1 microWatts per m2, for sensitive groups to 3 microWatts per m2 for children, to 6 microWatts per m2 for adults to 10 microWatts per m2 as an upper limit. What does these means? A wifi adaptor with antenna TX Power 20 dbm gives a power of 100 milliWatts. Around this antenna and in a radius of 1 meter, the power will be 7.95 milliWatts per m2 (correct me if i am wrong) which is equal to 7950 microWatts per m2. This is 79400% up from the upper limit of safe power, around an antenna. Because the power change according to the reverse of square of distance, it means that the distance is very important in order not to receive bad effects from radiation. If we move another meter from the antenna (2 meters) then the power will be 1980 microWatts per m2, thus we have 75.09% reduction, and if we move in 3 meters the power will be 884 microWatts per m2. But to achieve the limit of 10 microWatts per m2, we must go far from the antenna for many meters (~20). Now, if we change the TX Power to 23dbm (from 20dbm), we actually set a new power of double the one from 20dbm, that will be 200milliWatts. I saw you, before, that 20 dbm, is already by itself a very hight limit. Think, what is happening with 23 dbm, which actually double the power to 200mWatts from 100 milliwatts. I do not talk for a TX Power of 27dbm or 30dbm or more. It is for sure that the cell's membranes could not exchange K and Na ions, and will run out of energy and then...buy buy. (except possible damages to DNA).
- I do not say, not to use these devices because 1) i bought one, although i knew about the health harmful emissions of theme 2) there are people that work in the wifi industry and it would harm their wallets. I am just saying that you can take a distance from antennas, or use an aluminum foil between antenna and your body or use it for less hours or minutes. If you are in 27dbm or 30 or more, go out of room or use it for a very short time. I know there are people who use these, for many years and they are healthy now, but this kind of disease comes drop by drop. It is additive. So if you decide to use it, use it very carefully.

- My situation is so weird.
- I'm using Linux 4.14.0-kali3-amd64 xhci-hcd
- (USB)Wireless card AWSUS036NH
- Drivers rt2800usb
- (INERNAL) Wireless 7265
- Drivers iwlwifi
- When I first created the bootable USB Im using to run this Kali, I was able to change the reg Domain to BO but was not able to boost the tx power (but neither I get the message of Invalid argument)
- After tweaking for a bit now I'm not able to change the reg domain.
- Decided to follow this tutorial and I apply everything for country 00 (global) but when I do reg get I'm still stuck on the same regulation default values (stuck in 20)
- I'm able to change the txpower of my internal card to 22 txpower but no more, while in the external one 20 is the maximum.
- I'm quite lost to be honest never had such a problem. Is taking me days and I feel like I'm omiting something big. Let me know if any of you guys experienced the same.
- Thanks.
