Quick fix from upstream bug report for those that need this working asap (will be overwritten on next package update):

# sed -i s/GRO_DROP/GRO_MERGED_FREE/ /usr/src/rtl8821cu-5.4.1118f1bc7e8/os_dep/linux/recv_linux.c
# dkms install -m rtl8821cu -v 5.4.1118f1bc7e8
# modprobe 8821cu

@Ilgaz That package is for a separate upstream repo, which doesn't use DKMS. It's also available in the AUR: https://aur.archlinux.org/packages/rtl8821cu-git/

As for this one, it seems someone went ahead and reported the problem upstream: https://github.com/brektrou/rtl8821CU/issues/132

I am using it under kernel 5.12 on openSUSE TW via this package (perhaps it can help) https://build.opensuse.org/package/show/home%3ASauerland/rtl8821cu

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?

Skallwar commented on 2021-04-18 21:08

@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

@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 :)

riazufila commented on 2021-04-14 02:22

Does this driver work with WPA3 AP?

khvalera commented on 2021-03-08 21:23

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
