I followed these steps to setup rtl192eu driver for my TP-Link TL-WN823N wifi device and dkms status showed me that it was installed, but the connection is unstable, and I need to reconnect constantly to the wireless network.

Device TP-Link TL-WN823N V2 Ubuntu 16.04

How do I solve this? Why does ubuntu do not support this device automatically?

  • dkms status return "rtl8192eu, 1.0, 4.13.0-41-generic, x86_64: installed" and "8192eu" does not return anything May 19, 2018 at 20:30
  • I am using my home computer and it is working normally, but using the same device at my work computer sometimes gets unstable and stops working unexpectedly, as if the device did not exist. Maybe kernel version is not the same? How can I know which kernel is supported by this driver? May 19, 2018 at 20:33
  • From the office, when it is not running correctly, please run and post: dmesg | grep -e wlx -e 8192

After intalling 8192eu driver as following:

sudo apt-get install git build-essential dkms
git clone https://github.com/Mange/rtl8192eu-linux-driver.git
sudo dkms add ./rtl8192eu-linux-driver
sudo dkms install -m rtl8192eu -v 1.0

I noticed instabilities and weak signal. I solved it as follows:

echo "options 8192eu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/8192eu.conf
echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf

Reboot.

  • After looking everywhere this actually fixed my slow wifi issue. A very under rated answer.
