To all having an issue with this driver: please try https://aur.archlinux.org/packages/rtl88xxau-aircrack-dkms-git alternatively.

a patch to make it work for rpi and may be other ARM device:

 }

Note: I am seeing the interface of the usb wifi key marketed as DEEPOW dongle (from amazon) changing MAC address at every boot even though I have not set up anything like that in netctl, here.

I don't know if it's a hardware problem or driver problem. However, it's the same with rtl88xxau-aircrack-dkms-git driver

@concatenate: do you need 8812 or 8821 ? This is 8821au only. Now if the aircrack driver does not work too, it is unfortunately a problem difficult to solve, due to the fact these drivers are half open, half proprietary. EDIT: Alfa docs for your adapter are here: https://docs.alfa.com.tw/Support/Linux/RTL8811AU/ and indeed they mention 8812au, 8821au, aircrack but the title of the page says 8811au ! I know that Alfa is usually Linux friendly, have you tried to contact them? They also bring you to https://linux-hardware.org/index.php?id=usb:0bda-0811 and unfortunately it seems it is marked as "FAILED" for many systems.

I am currently on 6.6.49-1-lts kernel and I'm using the Alfa AWUS036ACS AC600 USB Wireless Adapter and WikiDevi says that this adapter uses the rtl8812au driver. I have tried literally almost every driver with no success. The LED turns on but the driver somehow messes with the kernel and hangs my PC. I can't use wireshark on the interface. I have tried rtl88xxau-aircrack-dkms-git and along with rtl8821au from morrownr from GitHub and it still does not work well (crashes and unresponsive). I believe the driver is not updated to the latest kernel and it's breaking something in the background. If anyone has an updated driver or a workaround to get it working, please let me know. I am devastated. :/

Downloading the latest snapshot, and building from the current master (7305e07) results in a working rtl8821au-dkms-git-5.12.5.2.r216.g7305e07 that properly builds with DKMS during kernel updates (currently at 6.6.1-arch1-1).

@zebulon This just broke on my system too. Happened fairly recently, but couldn't tell you the exact kernel update that put the kibosh on it. I'm currently on 6.4.6-arch1-1 but it might've been an update or 2 prior. Not sure if there's been any updates since your last post so bump for visibility. I'll buy new hardware if I need to, but the USB dongle I was using wasn't all that old really. Thank you!

@tag_enk: unfortunately it seems that this driver has not been yet updated to linux kernel version 6. This driver starts to be outdated and you may have better result with https://aur.archlinux.org/packages/rtl88xxau-aircrack-dkms-git.

tag_enk commented on 2023-02-20 16:25 (UTC)

Fair warning: this package broke after updating to Linux-LTS 6.1.12-1

Attempted to rebuild DKMS and it would fail to rebuild. Had to roll back to 5.15.94-1-lts in order to get my wifi back.

Would hold off on the latest Linux-LTS kernel if you see this before updating.

Hi all, I will work on updating the package asap.

Upstream sources have moved to git+https://github.com/morrownr/8821au-20210708.git.

zebulon commented on 2021-06-09 08:51 (UTC)

@leo95: indeed, thanks for the notice. Will do this by tomorrow.

leo95 commented on 2021-06-08 17:59 (UTC)

@zebulon you need to change the module name from 8812au to 8821au in the dkms.conf
