In my case enabling monitor mode and doing packet injection WORKS! as follows:

sudo apt update sudo apt upgrade sudo apt-get install linux-headers-uname -r build-essential dkms git clone https://github.com/Mange/rtl8192eu-linux-driver.git cd rtl8192eu-linux sed -i -E 's/CONFIG_WIFI_MONITOR\s*=\s*n/CONFIG_WIFI_MONITOR = y/' Makefile

sudo rmmod 8192eu rtl8xxxu r8188eu echo "blacklist rtl8xxxu" >> ./blacklist-rtl8xxxu.conf sudo mv ./blacklist-rtl8xxxu.conf /etc/modprobe.d/ sudo dkms add . sudo dkms install rtl8192eu/1.0

---

IF THERE ARE PROBLEMS WITH dkms, uninstall with dkms, then execute make commands manually: # sudo make # sudo make install

---

sudo modprobe 8192eu sudo lsmod |grep 8192eu

!To enable Monitor mode and test packet injection:!

WL=wlan0 sudo iwconfig sudo ifconfig $WL down sudo airmon-ng check kill sudo iwconfig $WL mode monitor sudo ifconfig $WL up sudo iwconfig

# Wait for a moment and retry if there are issues or reboot and try the " !To enable Monitor mode and test packet injection:! " steps sudo aireplay-ng --test $WL
