Building

Needed dependencies:

Package	URL
bc	https://ftp.gnu.org/gnu/bc/
gawk	https://ftp.gnu.org/gnu/gawk/
gcc	https://ftp.gnu.org/gnu/gcc/
make	https://ftp.gnu.org/gnu/tar/
tar	https://sourceforge.net/projects/net-tools/
zenity	https://gitlab.gnome.org/GNOME/zenity

With the automated script:

Keep in mind that the script checks your system and install the dependencies.
It also checks whether the file have or not have a variable inside.

Package	Command
curl	sh -c "$(curl -fsSL https://gitlab.com/KanuX/rtl8188eus/-/raw/master/scripts/build.sh)"
wget	sh -c "$(wget -O- https://gitlab.com/KanuX/rtl8188eus/-/raw/master/scripts/build.sh)"
fetch	sh -c "$(fetch -o - https://gitlab.com/KanuX/rtl8188eus/-/raw/master/scripts/build.sh)"

Without the automated script:

It is necessary the usage of kernel headers. Each distribution have a different package.
They can also be manually compiled. See this.

Compilation

Remember to run the commands as root.
Root can be accessed by doing su or sudo su command.

You will need to blacklist a older driver in order to use this one:

printf "blacklist r8188eu\n" > /etc/modprobe.d/realtek.conf

Now download the tarball and compile:

Package	URL
curl	curl -L https://gitlab.com/KanuX/rtl8188eus/-/archive/master/rtl8188eus-master.tar.gz --output rtl8188eus-master.tar.gz
wget	wget https://gitlab.com/KanuX/rtl8188eus/-/archive/master/rtl8188eus-master.tar.gz
fetch	fetch https://gitlab.com/KanuX/rtl8188eus/-/archive/master/rtl8188eus-master.tar.gz

tar -xvf rtl8188eus-master.tar.gz
cd rtl8188eus-master
make && make install clean
modprobe -r r8188eu
modprobe 8188eu

Important note: From kernel version 6.3+ the driver changed from r8188eu to rtl8xxxu.
