@logan2319 Hi! I seem to have made this exact mistake and cannot get my adapter to work. can you please help me out. I'm new to Ubuntu as well.

Hi @tapas05 

Can you post the result from the following terminal command? 

sudo lsusb.

I will find the right driver for you and help you install it.

Please include the type of hardware (pc/laptop/raspberry pi)

OS version and architecture (i386 or x64)

For anyone trying to get this working on Manjaro:

What you want is to install the rtl88xxau-aircrack-dkms-git package from the AUR using your package manager of choice. With yay, that's:

$ yay rtl88xxau-aircrack-dkms-git

It's likely that you'll be missing the necessary kernel headers, in which case you'll get the following error message:

==> Unable to install module rtl88xxau/r1164.b8167e6 for kernel *: Missing kernel headers.
 

If you have this issue, find your kernel version using:

$ Uname -r

This should return something like:

5.4.138-1-MANJARO
What's important is the two first numbers, in this case 5 and 4. Run

$ sudo pacman -S linux-headers

and select the appropriate headers from the list. In this case, linux54-headers, as the kernel version is 5.4.

Once you have the headers installed, you should be able to install the rtl88xxau-aircrack-dkms-git package normally and your tp-link adapter should just work.

@bossbob can i use this wifi in USB 3.0 port????  I have a MacBook air 2017.

@billserres Hi. You can use the adapter in USB 3.0 (will work on 2.0 protocol), unless you have a type-C connector for that usb 3.0

@bossbob thanks for posting the definitive answer here where I could find it. Just installed a T2U Plus on a LUBUNTU 20.04 system using these instructions.

Given TP-Link products are built using FOSS software, its an absolutely piss poor position TP-Link has taken by not giving back to the FOSS community by supporting us with Linux drivers. Absolutely pathetic.

I need help bro, I want to install this driver but my kernel doesn't have a package for header uname -r output when i type: 5.10.00-kali9-amd64

so the package I am trying to install linux-headers-5.10.00-kali9-amd64
but this package is not available in linux repositories so i am getting error how can i solve it please help i appreciate any kind of support

  @bossbob Thanks !!!!

  @bossbob I wish this worked for me. I can see the adapter when I execute a sudo lsusb, but Ubuntu 20.04 still cannot utilize the device
