TP-Link TL-WN823N does not work with rtl8192eu driver

[piucco]

I followed these (https://ubuntuforums.org/showthread.php?t=2351228&p=13601820#post13601820) steps to setup rtl192eu driver for my TP-Link TL-WN823N wifi device and dkms status showed me that it was installed, but it still does not work.

Device: TP-Link (https://www.tp-link.com/en/download/TL-WN823N_V2.html#Driver)TL-WN823N V2 (https://www.tp-link.com/en/download/TL-WN823N_V2.html#Driver)

I am using the following git repository: https://github.com/Mange/rtl8192eu-linux-driver

I believe the problem is the kernel version.

How do I solve this? Its very annoying to have to waste time trying to make a popular device work. Why does ubuntu do not support this device automatically? I cant undestand...

If I solve the problem manually, I'll probably have to keep doing this with every kernel update, right? That is terrible.

That shows that card is supported by the rtl8xxxu module
See the wireless script link in my signature and post results

[piucco]

Follow the script result: http://paste.ubuntu.com/p/mxmPxmsttn/

-edit

Sorry, I put another wifi adapter to use the internet and forgot to change to TP-Link, give me a second

[piucco]

Follow the correct result: http://paste.ubuntu.com/p/DdzB36y9QN/

Note: Sometimes changing usb port solves the problem for a while, but after some time the connection becomes inactive or unstable

[jeremy31]

Lets try
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, if it doesn't work at all do
sudo modprobe rtl8xxxu

[piucco]

The first 2 commands and reboot did not solve the problem

After reboot, I did "sudo modprobe rtl8xxxu" and the wifi started working and connected on the network, but with instability, from 10mb that I have, picked between 2 and 3mb only.

After all this I rebooted again and stopped working again.

I noticed one more thing, when I plugged in the TP-link device, my wireless mouse gets unstable, with interference

[jeremy31]

Reboot and run
./wireless-info
Then do the
sudo modprobe rtl8xxxu
Then post the new wireless-info.txt file

I am using my notebook right now, the last wireless-info was from my desktop at work. The problem persists, so I believe I can continue testing. Same kernel and ubuntu 16.04

I rebooted and here is my wireless-info: https://pastebin.com/rS8FSqmZ (tp-link device is not working)

After sudo modprobe rtl8xxxu: https://pastebin.com/YuWNzkm6 (tp-link device is working, but unstable)

Ok, I reinstalled the driver again as following and everything is working perfectly, i dont know why it did not work before...


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

Moved to Ubuntu/Debian based as it involves Elementary OS

I am not sure what happens in some of these kernels but I suspect the module is getting built against the wrong headers somehow
