  @MonkeyDLuffy 

thx !

I'm on 20.04 LTS and my pc is Asus R511L

The adapter is tp-link bluetooth 5.0 nano UB5A

 

all commands you describe are ok, but I have this message at the end:

"polinux<at>polinux:~/rtl88x2bu$ sudo modprobe 88x2bu

modprobe: ERROR: could not insert '88x2bu': Operation not permitted"

 

a reboot  don't soluce the trouble, and I can't see the adapter with "lsusb" command

Can someone help me ?

 

 

  @polinux I bought a TP-Link WiFi 6 Pcle WiFi card for Desktop PC AX3000 (Archer TX55E) Support Windows 11, 10 Only

Running the latest Ubuntu LTR which is 22.04. on an HP-Server.

Someone published a 3rd party Linux driver for it on one of the Ubuntu sites.  Installed that & it worked perfectly.

 

  @MonkeyDLuffy Thanks, it's works for me now!!!

At first, I followed guide in this article TP-LINK Archer T3U Plus - TechInfoDepot Wiki [1], but it doesn't work for me (looks like they supported only RTL8822bu, but ours is RTL8812bu), and the github repository has not been updated from 2019.

 

I tried your suggested and bump,... it's works like a charm, I can see two wifi cards in my laptop now.

 

Thanks for the day!!

I conturned the problem with this commad (founded in an another forum... sorry, I don't remember where):

 

polinux@polinux:~$ sudo ln -s rtl8761b_fw.bin rtl8761bu_fw.bin

 

at least, it's working perfectly

 

 

Congratulations, very good your explanation! Thanks a lot

  @BBiswas 

 

When, if ever, will we have oficial Linux support?

  @MonkeyDLuffy 

Just ran the commands and it worked fine for me also.  Thanks.  Just an FYI for anyone using this - on line 3 "VER=..." that is the number ONE in between the backslash and slash - not the letter L.  If you make this mistake as I did the FIRST time - just go thru it again and correct you mistake.

Thanks to all

This worked for me! Thank you so much!! (Apr. 29, 2024, on Ubuntu 22.04 LTS)
