If you put the source code on a permanent location,
this part of the procedure is necessary for a new i.e. an upgraded kernel:
$ cd /path/to/rtl8812au/
$ make clean
$ make
$ su
# cp 8812au.ko /lib/modules/$(uname -r)/updates/
# depmod
# modprobe -v 8812au
Thanks poma, I thought that might be the case. I already have
the source
in a permanent location, I'll also place a text file in there with these
instructions so I don't forget.
Is the updates directory the location the default location for depmod
and modprobe? If a make install is done that places the ko file much
deeper in the directory path in a wireless subdirectory.
Is there any possibility that this driver will make it into the kernel
by default, or is the chipset too new with insufficient usage for that
to happen?
