I have this problem:

sudo dkms install rtl8821CU/5.8.1 -k $(uname -r)

Kernel preparation unnecessary for this kernel. Skipping...

Hey! Does the driver+firmware+module support packet injection? I can get the monitor mode to work, but I can't seem to inject packets.

I'm a bit new to cloning stuff like git (I tried before with 8821au as a premade ZIP but that was wrong since mine is C not A) so I'm going to try and do that with GitHub desktop since my only internet connection is with windows and the whole point of doing the DWA-171 is to get internet on my lubuntu 32bit =/

once I copy and paste the folder (guess never zipped but it's small so who cares) then I guess I can follow steps from there, I hope...

@brektrou I am unable to compile it. Below are the details:

@J-Rojas Have the same problem. Found appropriate patch here: https://github.com/RinCat/RTL88x2BU-Linux-Driver/issues/81

And for the next compilation problem: https://github.com/gordboy/rtl8812au-5.9.3.2/issues/10

And it now works!! :)
