RTL8812BU WLAN NIC Adapter Driver

Hello all, I've been using Garuda Dr46onized for around 1-2 months now, and I absolutely love it. I alternate between Parrot Security OS, Garuda Dr46onized, and (Very rarely,) Windows 11 Pro as my daily driving systems, And honestly this issue affects every single one of them except for good old proprietary Windows 11 Pro.

I'm essentially looking for assistance regarding an NIC WLAN Adapter 802.11AC - And with the RTL8812BU chipset, and just below is the driver I currently use (which only has managed and very barebones monitor modes supported.) Virtual AP, AP mode, etc- Not at all functional but should theoretically work considering the adapter itself is capable of it.

My current RTL88x2BU Driver:

I would appreciate any possibility of assistance or maybe I simply missed a golden post or documentation that may have what I seek;
Here is the (relevant) output of garuda-inxi:

I believe my garuda-inxi provides far too sensitive of information for me to feel comfortable posting it all here, I can indeed reformat what is here, and perhaps add any more outputs you feel you may need from garuda-inxi. Thank you.

I think you should try rtl88x2bu-dkms-git from AUR

Hey thank you! I'll check it out. So I should probably remove the driver I currently use then?

Yes, I think so

Can i ask why do you think it gives to much away?


What issue?

I'm only on my cell and it is difficult for me to see everything sometimes, but I'm not seeing where you've described the issue you are encountering.

If your connection is being dropped regularly try disabling wifi power saving and/or IPv6.


And why don't you format it? It is exhausting to read in this format.

You can edit the post.

Which part(s) you mean?

It is not helpful to increase the font size in the first post to get answers.
It would be better to answer the questioner directly.

What are you doing on your PC that makes it so hot, including the GPU?
Crypto mining?

It appears they do some pen-testing of sorts, based on the fact that they use Parrot OS, so this could be caused by trying to crack hashes with a password recovery tool or something like that.

I am also rather curious about this opinion. To me, it seems like the most "sensitive" information in this output is the stuff they actually did post in the topic--but then again, I am not the pen tester here.


I asked this question a week ago, and as yet I have received no response. You have also ignored others queries. I see you were logged on the forum yesterday, but you made no attempt to provide more information on your thread. As such I'm deeming this thread abandoned and moving it to the dustbin as with no actual information this thread is worthless.
