I'm testing Ubuntu 18.04 with my current desktopand everything works correctly except for the Wi-Fi adapter. I'm using a TP-LINK TL-WN8200ND version 2.

As requested here, my wireless-info output is at this pastebin.

I've tested Mint 19, Kubuntu and KDE neon, with similar results.

Is there an official driver that works out of the box?

With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

sudo apt-get update

sudo apt-get install build-essential dkms git

git clone https://github.com/luckynzm/tlwn8200nddriver.git

cd tlwn8200nddriver

sudo dkms add .

sudo dkms install rtl8192eu/1.0

This will take some time; please be patient.

Next, blacklist the built in driver that isn’t working:

sudo -i

echo “blacklist rtl8xxxu”  >>  /etc/modprobe.d/blacklist.conf

exit

Reboot. Your wireless should be working.

I have been trying to make it work for the last couple of weeks, and finally I found a driver that works.

I am using Ubuntu 18.04, kernel 4.15.0-46.

What did work

I first try to install the rtl8192cu-fixes
(https://github.com/pvaret/rtl8192cu-fixes)

sudo apt-get update

sudo apt-get install git linux-headers-generic                 

build-essential dkms

git clone https://github.com/pvaret/rtl8192cu-fixes.git

sudo dkms add ./rtl8192cu-fixes

sudo dkms install 8192cu/1.11

sudo depmod -a

sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/

reboot

After reboot, it still not working for me, so I did:

sudo cp ./rtl8192cu-fixes/8192cu-disable-power-management.conf /etc/modprobe.d/

reboot

After installing the last driver, I tried this other, which was the one that actually worked (I did it in this order, the first can work for you so I suggest to try in this order).
From https://ubuntuforums.org/showthread.php?t=2340202

sudo apt-get install linux-headers-generic git 

build-essential

git clone https://github.com/Mange/rtl8192eu- 

linux-driver.git

cd rtl8192eu-linux-driver

make

sudo make install

reboot

It also says that if the kernel is updated do:
(so keep the directory)

cd rtl8192eu-linux-driver

make clean

make

sudo make install

Testing connection

The first thing to notice is that the led is going green.
On the top right click on wifi symbol and the network must appear (my internal adapter and the USB adapter in my case). You can connect to a wifi network here.
You can also check your adapters with:

iwconfig

You can also check it with:

lshw -short

Unplug it and run the command again to see which one was the usb adapter.

You can also create a hostpot, access point or station mode network with the command:

nm-connection-editor

Just as in Ubuntu 16.04.

What didn't work for me

I tried this drivers without success:

• git clone https://github.com/dz0ny/rt8192cu.git --depth 1


• git clone https://github.com/jeremyb31/rtl8192eu-linux-driver
  


• git clone https://github.com/luckynzm/tlwn8200nddriver.git
  


• git clone https://github.com/0xBADEAFFE/rt8192cu_dkms
  

I also tried to downgrade the kernel version to:

• 4.9.8


• 4.8.10 (ubuntu 18.04 didn't boot)


• 3.12.74 (ubuntu 18.04 didn't boot)
