TP-LINK Archer T9UH in 20.04 (kernel 5.4.0-58)

[en1i]

Hey to all!

I have 2 OS on my desktop, so I have tested TP-LINK Archer T9UH wifi adapter in the Windows 10 and it works fine.

However in the Ubuntu I don't able even to see it via lsusb: I received empty response. After reboot, lsusb works, but it freezes after the adapter inserted into any of USB slots.
I have tried to use https://github.com/aircrack-ng/rtl8812au and https://github.com/aircrack-ng/rtl8814au but it seems like there is no effect.

What should I do, any ideas? Mb I need to clean old drivers in some way. I could even install the another Ubuntu version if I was sure that this would help.

PS: my previous wi-fi adapter was TP-LINK TL-WN727N and it worked as expected.

System info: Linux version 5.4.0-58-generic (buildd@lcy01-amd64-004) (gcc version 9.3.0 (Ubuntu 9.3.0-17ubuntu1~20.04))

sure, thanks

Okay, by some reason lsusb started to work. What I have done: reboot -> mount old wifi adapter -> unmount it -> mount Archer T9UH
for now the lsusb is:

But still no Wi-fi icon. And the interesting thing: u can see that it detects T9UH - under the version 1. However, the adapter has label in the back side with a version 2

dkms status:

rtl8814au, 4.3.21, 5.4.0-58-generic, x86_64: built

so I have 3 different wireless drivers in the system. I think I should leave only one

[en1i]

Okay, I moved to "/lib/modules/5.4.0-58-generic/updates/dkms" , checked that I have "8812au.ko" folder inside.

Than I run

sudo dkms uninstall rtl8812au/4.3.8.12175.20140902+dfsg

checked that "8812au.ko" no longer exists
and "rtl8812au" no longer installed:
"dkms status"

nvidia, 450.80.02, 5.4.0-56-generic, x86_64: installed
nvidia, 450.80.02, 5.4.0-58-generic, x86_64: installed

rtl8814au, 4.3.21, 5.4.0-58-generic, x86_64: built

Then install rtl8814:

sudo dkms install rtl8814au/4.3.21

But it is not working. After the reboot "lsusb" didn't respond again. So I think rtl8812au is the correct version, but by some reason it doesn't work

[en1i]

Seems like TP-LINK adapters in not working with the latest kernel versions (from 5.3.42)
https://github.com/aircrack-ng/rtl8812au/issues/645
How to downgrade to another version?)

[jeremy31]

You actually need the rtl8814au version from the aircrack-ng repo on github. They took that one out of rtl8812au recently

https://github.com/aircrack-ng/rtl8814au

[en1i]

Kicked it working.
What I have done: downgraded kernel version, reboot in it and reinstall drivers for adapter

Working kernel:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.2.21/
Instruction how to install another kernel: https://ubuntuhandbook.org/index.php...tu-linux-mint/
Reboot after installation
Select in grub loader "Additional", then select chosen kernel version
Then u need to reinstall drivers for wifi adapter. In my case, working repository is https://github.com/aircrack-ng/rtl8814au

cd ~/Downloads
git clone https://github.com/aircrack-ng/rtl8814au.git
sudo dkms add  ~/Downloads/rtl8814au
sudo dkms install rtl8814au/4.3.21

[jeremy31]

I see this in the source code {code] {USB_DEVICE(0x2357, 0x0106), .driver_info = RTL8814A}, /* TP-LINK Archer T9UH */[/code]
The aircrack-ng/rtl8812au repo doesn't support the rtl8814au any more, but if your download in /Downloads is old enough it might work. Post URL from terminal for
