Build driver for 0bda:c811 Realtek Semiconductor Corp. 802.11ac NIC

English Hardware

Hi,
Trying to build a driver for the above hardware, on Leap15.3, and had it working for Leap 15.2, but apparently the driver doesn’t like the kernel version? 5.3.18-59.5-default
|Have tried building a couple of drivers from GIT (https://github.com/brektrou/rtl8821CU.git + https://github.com/whitebatman2/rtl8821CU) but can’t get anything to build on the Kernel.
Not an expert at this developer stuff, would anyone have any hints for me??
Thanks.

It depends on you running kernel, so post

uname -a
#3

Edit:
seen:

5.3.18-59.5-default

Connect with LAN cable and add my Repo:

zypper ar -f https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Leap_15.3_Update/ Sauerland-Update

Install it:

zypper in rtl8821cu-kmp-default

If you want to use the git-Version, you have to patch it, because the openSUSE kernel in Leap 15.3 is a backported Kernel 5.9.

Brilliant, thanks, works a treat!
Will this need updating when kernel patches are applied?

And, even better, I also have a Bus 001 Device 018: ID 0bda:b812 Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey]
which is now working also!
Thanks, doubled!!

Automatically over my Repo.

And, even better, I also have a Bus 001 Device 018: ID 0bda:b812 Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey]
which is now working also!

But that is supported by rtl8822bu

Yeah not real sure how it happened (after I added your repo??), went in to Yast>Software, the other device was plugged in, and the other, correct software package was already selected (?? - am i going crazy??), installed and all worked fine!
Thanks.
