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

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.

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

It looks like all rtl88xx drivers are having problem with 5.3.1 kernel. I am looking into this to see if we need a patch to handle a kernel API change.

@mrpanda: I can confirm I am having the same experience.

Not working with Qoltec 57010 rtl8811au hardware on 5.3.1 no installation problems , but it seems that it has no power the indicator is dead. It seems that no Aur package is working for rtl8811au on 5.3.1.

@jschuster: you are right, those are not even installed, they just stay in the src tree and are not used. The problem you describe is indeed very strange. You may want to ask on the forums, or on the ip developers mailing list.

@zebulon I temporarily moved those files out from my /usr/src/rtl8821au-5.1.5.r78.gecd3494 directory (where pacman says they were installed) - is that what you meant? I can't tell if there's another step where they're "installed" from here, since I would expect this directory is only used for building source code, but I can't seem to find any step beyond this.

In any case, rebooting after moving those files didn't seem to affect anything. I'm connected to the network just fine, and I don't see anything suspicious in the system logs.

@jschuster: interesting. The main difference (other than the driver itself) is that I package also ifcfg-wlan0, runwpa and wlan0dhcp files. As far as I am awaree, they come from the Ubuntu world, and I am not even sure they even interfere with netctl in Arch. Could you please check what happens if you move/delete those files from your system?
