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

@Casper: see also https://askubuntu.com/questions/1162974/wireless-usb-adapter-0bdac811-realtek-semiconductor-corp for a discussion about 8821cu. By the way, there is a PKGBUILD on AUR for the brektrou driver: https://aur.archlinux.org/packages/rtl8821cu-dkms-git/

@Casper: I see your Device ID in the Github Issue report: 0bda:c811. Seems that from reading https://github.com/aircrack-ng/rtl8812au/issues/721 you may have an RTL8821CU. Can you look if: https://github.com/ulli-kroll/rtl8821cu or https://github.com/brektrou/rtl8821CU compile and work for you?

@Casper: it looks like the API has changed with 5.12 version of the kernel and therefore does not compile. Very strange the aircrack driver does not work either - this would have simplified the problem. Maybe you could raise a ticket in aircrack Github repo while I try to fix this? Maybe this is just an ID missing in aircrack code? Do you know your device ID ? In addition I do not own a 8821au adapter, making fixing quite difficult.

Unable to compile. Also created an issues in github: https://github.com/zebulon2/rtl8812au/issues/36.

Unfortunately my usb wi-fi adapter works only with this driver, it doesn't appear with rtl88xxau-aircrack.

@zebulon, you could always change the upstream to one that works rather than remove the package? And, so there's no conflict with rtl88xxau-aircrack-dkms-git this one could provide the v5.3.4 branch?

Hello everybody, I think it is time to retire this package and direct users to the more recent rtl88xxau-aircrack-dkms-git package. Any suggestion against this?

Based on @solstice's pinned comment and as of today, this is a working patch for the RBPI. I'm simply adding 'armv7h' to the architecture list:

I used a RPI 4 model B rev 1.1, with archlinuxarm (Linux rpi4 4.19.108-1-ARCH #1 SMP PREEMPT Tue Mar 10 02:06:04 UTC 2020 armv7l GNU/Linux) and an Ourlink AC600 Wireless USB adapter:

@zebulon Thanks already tried it same issue , for now I'm using different usb wifi module. If you can make the patch that will be awesome.
