How to increase TX-Power of Wi-Fi adapters in BlackArch in 2022

Theory about increasing TX-Power of Wi-Fi adapters was already discussed in the article ‘How to increase TX-Power of Wi-Fi adapters in Kali Linux’. There you will find fundamentals of TX-Power increment and the guide, suitable for Kali Linux, and for BlackArch partly.

For BlackArch we will use power of AUR (Arch User Repository). In BlackArch/Arch Linux it is enough to install wireless-regdb-pentest – Central Regulatory Domain Database with txpower/channels modified for pentesters.

First, we start from crda and wireless-regdb installation:

sudo pacman -S crda wireless-regdb

Actually, crda and wireless-regdb is unnecessary, but without them wireless-regdb-pentest installation will fail.

Now we install wireless-regdb-pentest:

git clone https://aur.archlinux.org/wireless-regdb-pentest.git
cd wireless-regdb-pentest
makepkg -si

You will be asked:

wireless-regdb-pentest and wireless-regdb conflict. Remove wireless-regdb? [y/N]
wireless-regdb-pentest and crda conflict. Remove crda? [y/N]

It is necessary to select ‘Y’ in both questions.

Reboot your system.

Everything is done!
