@Nudin: are you sure the 8812au module is loaded (and has been compiled for your current kernel)? Please check this is the correct driver for your adapter (which one is it?).

@arthurwatt-veea: this is very technical and unfortuantely probably outside of the scope of this forum. That said, would you like to try the 5.3.4 from https://github.com/aircrack-ng/rtl8812au/tree/v5.3.4 The aircrack-ng team is very active maintaining this version, unified for 8812au,14au and 21au, and they also be helpful around these very technical aspects. And if you could please report back here, since at some point it may be interesting to update to 5.3.4.

I installed it succesfully but I can't get the interface up:
$ sudo ip link set dev wlan1 up
RTNETLINK answers: Operation not permitted
Any ideas?

Hello folks (@zebulon) I have been trying to setup an AP on DFS channels with this driver. With a 4.14 kernel and hostapd version 2.6 this does work. Looking at the code it seems that the DFS radar cfg80211_ops have not been implemented. When testing I did the following changes: enabled CONFIG_DFS_MASTER build flag set cfg80211 country modprobe parameter (ieee80211_regdom) implemented a null cfg80211 radar interface to keep hostapd happy set the rtl8812au domain module parameter (rtw_dfs_region_domain) Setting the rtw_dfs_region_domain seemed to cause things to go a bit wonky (like not marking the DFS channels as radar detect, so hostapd did not do CAC). There seems like a fair bit of code to handle DFS channels in the driver, but it is not clear what level of support is present.
Do we expect DFS channels to work on this version of the driver?
Thank you Arthur

@arthurwatt-veea: thanks a lot for your work on the code. When you are ready, please fork one of the rtl8812au repos (such as gordboy's or the aircrack-ng) and propose your patches. One patch per issue being better than a big one addressing several ones, as you might already know. The earliest these patches are being added and tested (to ensure they do not introduce side effects), the better.

The bug is present in 5.1 and 5.2 repos. I guess there is not much testing of IBSS. My next job is to try and get IBSS working securely with RSN.

@arthurwatt-veea: that is great work. Has the bug been introduced in 5.2? The codebase is very different from 4.3 (and 5.1 as far as I remember). What I would recommend to do is for you to fork a github repo (such as gordboy's or aircrack-ng), commit your change and send a pull request to various rtl8812au repos. They do not need to be the same than the one you used for your fork of course.

Thanks Zebulon. Before cutting through the repos I wanted to make sure the driver was not receiving the multicast packets and then discarding them. I then found that the multicast frames were being received and then discarded. The fix is fairly straightforward, not sure which repo I should push the change to, there seem to be so many....

@arthurwatt-veea: 2 possibilities here: 1) would you like to try 5.3.4 version of the driver from: https://github.com/aircrack-ng/rtl8812au/tree/v5.3.4 and let me know if that corrects the issue. 2) Also, does reverting to 5.1.5 work? You can install package https://aur.archlinux.org/packages/rtl8821au-dkms-git/ and check (this one works for 8812au too). Please let me know which one works.

To all having an issue with this driver: please try these alternate packages: https://aur.archlinux.org/packages/rtw88-dkms-git or https://aur.archlinux.org/packages/rtl88xxau-aircrack-dkms-git.
