How do I get a TP-Link TL-WN823N V3 wireless adapter working?

Sorry to bother you with this, but I'm not really an expert and it may be the most stupid thing you'll see. I have ubuntu 19.04 (kernel: 5.0.0-13-generic; gcc version: 8.3.0) installed on an old pc that has a broken wifi card. So I replaced it with an external tp link wireless usb adapter. But I cannot follow the instructions:

I already downloaded these files and sent to the pc from another one, as it has no internet connection:

https://www.tp-link.com/en/support/download/tl-wn823n/#Driver

It may be a really stupid thing, but if I have, fe, to compile (I don't even know what it means) the driver, I don't know what it means " go to the driver directory and run the following commands ".

I really appreciate anyone and anything that helps me to solve this.

If you have internet access by any other means (wired or through USB tethering), you can installed the RTL8192EU drivers for your TP-LINK TL-WN823N wireless adapter from Mange's GitHub repo. Here are the steps as described on the GitHub page:

Building and installing using DKMS

(1) Install DKMS and other required tools:

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

(2) Clone this repository and change your directory to cloned path.

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

(3) Add the driver to DKMS. This will copy the source to a system directory so that it can used to rebuild the module on kernel upgrades.

sudo dkms add .

(4) Build and install the driver.

sudo dkms install rtl8192eu/1.0

(5) Distributions based on Debian & Ubuntu have RTL8XXXU driver present & running in kernelspace. To use our RTL8192EU driver, we need to blacklist RTL8XXXU.

echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf

(6) Force RTL8192EU Driver to be active from boot.

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

(7) Newer versions of Ubuntu has weird plugging/replugging issue (Check #94). This includes weird idling issues, To fix this:

echo "options 8192eu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/8192eu.conf

(8) Update changes to Grub & initramfs

sudo update-grub; sudo update-initramfs -u

(9) Reboot system to load new changes from newly generated initramfs.

systemctl reboot -i

(10) After the reboot, you can check that your kernel has loaded the right module:

sudo lshw -c network

You should see the line driver=8192eu

In addition to @Jags' comment, there is a simpler script to automate all his/her steps under the following repo.

I have validated myself on Ubuntu 20.04 and it works wonderfully.

• Clone this repo: git clone https://github.com/clnhub/rtl8192eu-linux
• Under the repo, run ./install_wifi.sh

Done! :)
