Doesn't seem to compile for kernel 5.12. I'm getting this error:

==> dkms install --no-depmod -m rtl8821cu -v 5.4.1118f1bc7e8 -k 5.12.1-arch1-1
Error! Bad return status for module build on kernel: 5.12.1-arch1-1 (x86_64)
Consult /var/lib/dkms/rtl8821cu/5.4.1118f1bc7e8/build/make.log for more information.

Checking the make.log file, the problem seems to be this:

/var/lib/dkms/rtl8821cu/5.4.1118f1bc7e8/build/os_dep/linux/recv_linux.c: In function ‘napi_recv’:
/var/lib/dkms/rtl8821cu/5.4.1118f1bc7e8/build/os_dep/linux/recv_linux.c:358:55: error: ‘GRO_DROP’ undeclared (first use in this function)

Same error for the linux-zen kernel, which is also on 5.12.1. It still compiles just fine for the LTS kernel (5.10.34-1-lts), so I'm guessing this driver doesn't work with 5.12. Can anyone confirm the issue so it can be reported upstream?

Is there any advantage in using the 5.8.1 version?

@khvalera There was a fix on the repo page. I have updated the PKGBUILD let me know if it's working now

Skallwar commented on 2021-04-18 19:22 (UTC)

@khvalera Is it specific to this package or it does not work either using the upstream repo directly ?

@riazufila I don't know. Try it and let us know :)

Does this driver work with WPA3 AP?

khvalera commented on 2021-03-08 21:23 (UTC)

does not work under armv7h

There is a patch making this dkms module compile&work on Debian and now openSUSE. I tested the patch on openSUSE TW and it works with kernel 5.10.rc5 . see https://github.com/brektrou/rtl8821CU/issues/100#issuecomment-733511163

@simona I am afraid not. I have a kernel supported USB dongle too and it works right after plugging. Realtek does not (it has led too,not lighting).

simona commented on 2020-11-22 17:01 (UTC)

newer kernel core has it inside?

I have tested Manjaro kernel 5.10.rc4 right now on "testing" branch Intel i5 64bit system. Unfortunately it fails stating "error 10" when switching kernel. I have the git tree locally too and manually trying to build fails too.

Update: Here is the reason why. Unless those API calls change there is a little hope it will work in 5.10
