I fail to compile its GPL Source Code on CentOS 7.4.
Where to get its rpm drivers, or how to compile its GPL Source Code?
Looks like you've found the only official source code.
It looks like someone else has (unofficial) code here:
https://github.com/abperiasamy/rtl8812AU_8821AU_linux
It isn't a driver supported by the CentOS kernel, nor any 3rd-party
repositories that I know of. You'll either have to get it to work
yourself or use a newer kernel (which isn't something supported on
CentOS, but provided by 3rd party repos such as elrepo.org.)
I'm generally not willing to package these Realtek sources for
Enterprise Linux as the code is often heavily dependant upon kernel
versioning with lots of conditionals. This approach simply does not work
on RHEL (or CentOS), where for example el7 uses a nominal 3.10.0 kernel
but has a wifi stack that is backported from linux-4.14. For these
Realtek drivers to be properly supported on RHEL (and CentOS), Realtek
need to perform RHEL versioning checks (RHEL_MAJOR and RHEL_MINOR) in
addition to their kernel versioning checks.
My advice - if Realtek isn't prepared to support the device on RHEL (or
CentOS), purchase an adapter that is natively supported.
