If it crashes, try your luck with these:
$ git clone
https://github.com/gnab/rtl8812au.git
$ cd rtl8812au/
...
$ git clone
https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git
$ cd rtl8812AU_8821AU_linux/
...
$ make
$ su
# cp 8812au.ko /lib/modules/$(uname -r)/updates/
# depmod
# modprobe -v 8812au
Thanks poma, I'll check these out. The git source might be
better than
what I have at the moment as the vendor source I have seems to be
requiring kernel config parameters that appear to not be active in the
kernels I am using.
