USB Wifi TP-Link AC600 cannot work with newest version

[kienngd]

I use Ubuntu 24.04 Kernel: 6.8.0-31 Wifi: TP-Link AC600 wireless Realtek RTL8811AU [Archer T2U Nano] ID 2357:011e I install by command sudo make dkms_install with newest version, wifi will disconnect after init. So I cannot list wifi list. But if I reset code to commit 63cf0b4584aa8878b0fe8ab38017f31c319bde3d. Wifi works fine.

Just wanted to add my report that the latest version fails to find networks with my TP-Link Nano USB AC600 Archer T2U but using a fresh clone and switching to https://github.com/aircrack-ng/rtl8812au/commit/63cf0b4584aa8878b0fe8ab38017f31c319bde3d has it working. Other than that, this is already the best, fastest and most stable of the 3 drivers I've used so far so big thanks to the developers and hopefully the latest issues can be fixed soon.

My kernel is: 6.10.6-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.10.6-1 (2024-08-19) x86_64 GNU/Linux.

For both latest and detached versions, I get a nasty trace message during boot that wasn't there before and I haven't updated any system packages either. I won't share it since I'm using the older version now and everything is fine.

I also ran into the same issue on Linux Mint 22, using commit https://github.com/aircrack-ng/rtl8812au/commit/63cf0b4584aa8878b0fe8ab38017f31c319bde3d solved it for me as well. I hope this regression gets fixed in the latest version soon.

Thank you all so much. I also got stuck in installing the driver for TP-Link Archer T2U Nano (Realtek rtl8811au) in Xubuntu 22.04. I could do this in live usb smoothly, but I got an error when installing Xu on my old hard drive. ERROR (dkms apport): binary package for 8812au: 5.6.4.2_35491.20191025 not found I surfed a lot and tried many ways like using old version (5.3.4), using rtl8812au-dkms (from ppa:kelebek333/kablosuz) but all failed, still got the same error or successfully installed but couldn't connect to wifi. After all, I tried the way in this page and it worked with the git code 63cf0b4 and two commands: sudo make then sudo make install. The driver was not shown in dkms but it worked after I rebooted. (I got error when running sudo make dkms_install, the installing process showed some error and DKMS showed the package installed with a warning 'built different from installed')

I was also having this issue. I originally installed the most recent version using dkms, but it didn't work and I tried a few times with no success. But I got it working.

Ill share what I did to hopefully help others, but I'm not totally sure exactly what steps were important to fixing the issue:

• Unplugged the USB adapter
• Ran dkms status to find the name of the dkms module I had installed.
• Used sudo dkms remove <module name> --all to delete the old driver (replace module name with the name from the prev step).
• Restarted computer.
• Fully deleted the git folder (rtl8812au) so that I could re-clone it with no changes.
• Used git clone https://github.com/aircrack-ng/rtl8812au.git to redownload the files.
• cd rt*

• Then I decided to update everything just to be sure:

  • sudo apt-get update
  • sudo apt-get install bc mokutil build-essential libelf-dev linux-headers-`uname -r`
  • sudo apt-get upgrade
• Then, I did git checkout 63cf0b4 to set it to the known working version, and a git status just to be sure there were no changed files.
• Ran sudo make, and then sudo make install.
• Finally, sudo service NetworkManager restart, and then I plugged in the USB adapter and it worked.

Holy god!!! Bro, you are a true hero!! Work for me!!!!

One more thing I'd like to share is, I also got the error of lacking package pahole and 'Skipping BTF generation xxx. due to unavailability of vmlinux' while compiling (run sudo make). I solved this after reading an article on askubuntu. The compiling process need the vmlinux file in /usr/lib/modules/uname-r/build but it's not there. The compiling process succeeded after I installed the package pahole and created a symlink for the vmlinux file (located in /sys/kernel/btf) in the above folder. Besides Xubuntu 22.04, changing git code to 63cf0b4 is also a must in Linux Lite 6.6. In live usb Linux Lite 6.6, I forgot changing the git code but the installation process still worked, so I skipped this step in Linux Lite (official installation on hard drive). I saw the compiling process had some warnings, not run smoothly. I still could install the driver but couldn't connect to the internet wifi at home. Then I had to remove the driver by sudo make uninstall. In the second installation, I changed the git code to 63cf0b4 and it worked!

@NoDuckyAnyMore

Same here. Did it like you and just works fine now.

but after the git checkout i also did

• 32-bit ARM architecture (RPi 1/2/3/ & 0/Zero):

  $ sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
  $ sed -i 's/CONFIG_PLATFORM_ARM_RPI = n/CONFIG_PLATFORM_ARM_RPI = y/g' Makefile

  Or, for ARM64 (RPI 3B+, 4B and Zero2) you will need to run:

  $ sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
  $ sed -i 's/CONFIG_PLATFORM_ARM64_RPI = n/CONFIG_PLATFORM_ARM64_RPI = y/g' Makefile

AND

ARM32

$ export ARCH=arm
$ sed -i 's/^MAKE="/MAKE="ARCH=arm\ /' dkms.conf

Or, for ARM64 run the following before re-building:

$ export ARCH=arm64
$ sed -i 's/^MAKE="/MAKE="ARCH=arm64\ /' dkms.conf

like mentioned in the Readme.
