Hi Larry, Sorry for sending you down a rabbit hole. The reason the DKMS steps didn't work is that the git repository for the rtl8814au lacks the configuration file(s) for DKMS. Specifically, if you check your logs, you'll see that if failed to locate DKMS.conf. I thought it would work because the rtl8814au driver appears to be based off the driver here: https://github.com/gnab/rtl8812au. That driver does have the configuration files to support DKMS (Makefile.dkms and dkms.conf). I don't know enough about DKMS to modify the configuration files in the above repository to make it work with the rtl8814au git repository.
Fortunately, you can still compile the package for your existing kernel. The only downside of this step is that you will need to re-compile the drivers if you install a new kernel which is not ABI compatible. For example, the current Stretch kernel for AMD64 is linux-image-4.9.0-3-amd64 (4.9.30-2+deb9u2). Thus, it should work with any future kernel starting with linux-image-4.9.0-3, but if you see 4.9.0-4, you would likely have to recompile. I haven't actually tested this, but it's what I've read. In any case, since you've already installed the build dependencies, you just need to do the following: #Clone the git repository (again) - Might as well work from a fresh directory git clone https://github.com/astsam/rtl8812au.git cd rtl8812au #Compile driver for your hardware make RTL8814=1 #Install Module make install #With Wifi adapter connected, load Module (If this fails, reboot and it should load the correct module.) modprobe 8812au Regards, Jason
