Type “sudo make install” to install the driver file. following the instruction from the installation guide this error

The download page says: "Operating System: Linux (kernel 2.6.24 ~ <4.9.60)" Ubuntu 22.04 uses a much more recent kernel, 5.15.0-xx. In other words, the official driver is too old. Please edit your question to show the result of the terminal command: lsusb Welcome to Ask Ubuntu. — chili555, Sep 19 '22 at 13:30
Your device 2357:0109 TP-Link TL WN823N RTL8192EU is covered by the driver rtl8xxxu that’s included in recent Ubuntu versions. May we see: sudo modprobe rtl8xxxu && sudo dmesg | grep 8xxx — chili555, Sep 21 '22 at 13:25
You should post the results of the command so that we may review them. — chili555, Sep 21 '22 at 14:19

Installing the RTL8192EU(TP-LINK WN823N)

Installing headers:

sudo apt-get install git linux-headers-generic build-essential dkms

Clone Repository:

git clone https://github.com/Mange/rtl8192eu-linux-driver
cd rtl8192eu-linux-driver

Adding Driver to DMKS:
```
sudo dkms add .
```
Build and install driver:
```
sudo dkms install rtl8192eu/1.0
```
Distributions based on Ubuntu have RTL8XXXU Driver present running in kernelspace. Since We install rtl8192eu, we should blacklist the RTL8XXXU by running this command:
```
echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf
```

Forcing the RTL8192EU to run in boot:

echo -e "8192eu\n\nloop" | sudo tee /etc/modules

Update change to GRUB/BIOS & inittramfs:

sudo update-grub; sudo update-initramfs -u

Then reboot:

systemctl reboot -i

Sumarize: if you using latest ubuntu 20.04 LTS Very Recommended to install via git dmks, my ubuntu version was 22.04 LTS Latest Trying To Compile with the TL823N showing error(ubuntu 22.04 kernel isn't support, since it only support 5.15.0-xx). try to install from gitclone https://github.com/Mange/rtl8192eu-linux-driver (latest),after adding the to dmks, it won't readable because there is a RTL8XXX driver, by blacklisting(or disable) the driver the RTL8192EU Swith be primary driver because rtl8xxx was disable.
