Increase wifi transmit power alfa12/29/2023 If you try txpower at 33 without changing the domain, you get an error, but once you change your regulatory domain you are good to go!Īnd that's all you need to know on BackTrack! Step 7: KALI Users Every 3 decibels is approximately double that of the prior power, so 30 dBm is 1000 mW, if we add 3 dBm, then we can double the power such that 33 dBm is about equal to 2000 mW. 10 dBm equals 10 mW, 20 dBm equals 100 mW, 30 dBm equals 1000 mW, and so on. In that case, Find out which country your card believes it is in and change that country's configurations.Įvery 10 decibels is a 10X increase in power starting from 1 dBm equal to 1mW. UPDATE: Some wireless cards like the AWUS036NHA may be stuck in a country and cannot be changed from that country. Don't have the antenna in your mouth while transmitting at 2 watts or you may get cancer. There is no limit computer-wise, but be careful, the stronger the transmission power, the more dangerous it can get for your health. The number you are replacing is in decibels, so you choose how much you want. If your card can go up to 2000 mW, then you would change that number to 33, which stands for 33 dBm, which is approximately 2000 mW. apt-get install python-m2crypto libgcrypt11 libgcrypt11-dev libnl-dev.Step 1: Install Packagesįor this to work, we need to install a couple packages first, and those packages are as follows: The differences occur in Steps 4 through 6. Go to Step 7 to learn what the differences are. NOTE: KALI users have to do it just a tad bit differently. So without further delay, let's get into how to change that! In Bolivia, the rules are that you can set your txpower to 30 dBm and no more, but if we were to change those rules, we could change how much we can increase it to. What happens is that the iw reg set command reads the regulatory database for the country that you specified (BO) and comes back with the rules for that country. If you try to go over 30, though, you will get an error. I'm going to quickly review the commands to do so: OTW showed you how to set your TXPOWER all the way to 30 dBm, or 1 full watt, or 1000 mW. In this article, OTW pointed out one use for increasing the TXPOWER, such that we can overwhelm local APs so that a user may connect to our AP instead of the authentic AP. Changing Your Wi-Fi Card's TX PowerĪ while ago, OccupyTheWeb posted an article on how to create an evil twin. Please be careful putting this into action. 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. Removing all restrictions is illegal in the United States. Well, I will show you how to break that barrier and go as high as you want! WARNING Do you have an Alfa AWUS036NH Wi-Fi adapter that claims it can go to 2000 mWs, or some card that can supposedly transmit power over 1000 mW? If so, you may have run into problems setting your card's TXPOWER higher than 30 dBm, which is about 1000 mW.
