thanks for the info
but i don’t know much about linux
it would be very helpful if you give me all the commands
in ubuntu i tried this and it worked

sudo apt update
sudo apt-get install mokutil && mokutil --sb-state
sudo apt-get install git linux-headers-generic build-essential dkms
git clone GitHub - clnhub/rtl8192eu-linux: Realtek rtl8192eu official Linux driver, versions: 5.2.19.1 (master), 5.6.3.1, 5.6.4 and 5.11.2.1 (default)
cd rtl8192eu-linux/
sudo dkms add .
sudo dkms install rtl8192eu/1.0
echo “blacklist rtl8xxxu” | sudo tee /etc/modprobe.d/rtl8xxxu.conf
now what should i use in fedora?

Make sure to fully upgrade the system and boot the latest kernel:

sudo dnf upgrade --refresh

Then build the modules with DKMS:

sudo dnf install git dkms kernel-devel openssl
sudo git clone https://github.com/clnhub/rtl8192eu-linux.git \
/usr/src/rtl8192eu-git
sudo sed -i -e "/^DEST_MODULE_LOCATION/s|/kernel/.*/|/extra|" \
/usr/src/rtl8192eu-git/dkms.conf
sudo dkms add rtl8192eu/git
sudo systemctl restart dkms.service
sudo tee /etc/modprobe.d/rtl8192eu.conf << EOF > /dev/null
blacklist rtl8xxxu
EOF
sudo tee /etc/modules-load.d/rtl8192eu.conf << EOF > /dev/null
8192eu
EOF
sudo systemctl restart systemd-modules-load.service

Form enrolling request if you need Secure Boot:

MOK_PASSWD="fedora"
sudo mokutil -i /var/lib/dkms/mok.pub << EOI
${MOK_PASSWD}
${MOK_PASSWD}
EOI

Or disable Secure Boot in the BIOS/EFI settings.
