Which Debian Stretch package provides firmware for the Realtek
RTL8814U chip? In particular, the Comfast CF-917AC 1750Mbps USB3
adapter: https://www.amazon.com/dp/B01B75MHR0 .
Kali Linux supports the RTL8814 natively:
https://www.kali.org/news/kali-linux-20171-release/ . Further, there
are some clues here: https://bugs.kali.org/view.php?id=3260
https://github.com/diederikdehaas/rtl8812AU
https://github.com/astsam/rtl8812au
https://github.com/lwfinger/rtlwifi_new
But, I'm looking for an "official" Debian firmware package.
I wasn't able to find the rt8814 mentioned here:
https://www.debian.org/distrib/packages nor here:
http://linux-wless.passys.nl/query_chipset.php?chipset=Realtek
nor here: https://wireless.wiki.kernel.org/en/users/drivers

Have you firmware-realtek installed? It is available in the non-free repos.

"These drivers are not part of the standard Linux kernel"
The kali realtek-rtl88xxau-dkms package probably just
downloads the driver from github and installs it for the running kernel.
Since the github projects do not refer to firmware files I assume there
are no special firmware files needed.

I have the Edimax EW-7822UAC (2x2 802.11ac) which uses the rtl8812AU chipset. I can confirm that the firmware-realtek package does not contain support for the rtl8812AU chipset, and presumably also does not support the RTL8814U chipset. Neither are listed on https://wiki.debian.org/rtl819x. In contrast, Ubuntu and its derivatives, such as Mint, do package this driver. For example, see https://packages.ubuntu.com/xenial/kernel/rtl8812au-dkms.
Fortunately, I was able to compile and install the rtl8812AU driver from https://github.com/diederikdehaas/rtl8812AU without difficulty. I have been using this wireless card on a desktop system with Stretch. It has been reliable and I had no problem configuring it with networks running WPA2-PSK and WPA2-Enterprise (EAP-TLS). I'm getting speeds around 300 Mbit/sec @ 65-70 dbm when connected to a Ubiquiti AC-LR. In contrast, Mint installed the driver for me without issue but had constant issues with EAP-TLS due to bugs in network-manager.

Thank you for the information you have provided.
Is there a chance the rtl8814AU driver might be available as a backport?
I was hoping that I wouldn't have to compile the driver, but your experience
has left little doubt that it will be necessary. Although I have
successfully built several Software Defined Radio applications, I've never
been successful in building drivers. Will ModuleAssistant
<https://wiki.debian.org/ModuleAssistant> assist in building the driver? Or
is there another "assistant" package that may be of help?
Best regards,
Larry

Hi Larry,
The drivers you need are not available as a backport because no Debian
release packages said drivers. You'll need to compile them
yourself. However, the process should be fairly easy.
I think you want the drivers from here: https://github.com/astsam/rtl88
12au
1) This is the easy way but will only work for your existing kernel,
and presumably any future ABI compatible kernel
#Install dependencies
sudo apt-get install linux-headers-$(uname -r) build-essential git
#Clone the git repository
git clone https://github.com/astsam/rtl8812au.git
cd rtl8812au
#Compile driver for your hardware
make RTL8814=1
#Install Module
make install
#Load Module (I compiled this myself and the created module appears to
be 8812au, not rtl8814. If this doesn't work, just reboot with the
device connected, and it will load the correct module.)
modprobe 8812au
I don't have your hardware so I can only test the compilation, which
worked on my Debian Stretch system. This appears to be the driver that
is used by Kali Linux, so it should work for you.
2) This method is a bit more involved but will use DKMS to ensure that
the drivers are recompiled when your kernel is updated.
#Install dependencies
sudo apt-get install linux-headers-$(uname -r) build-essential dkms git
#Set environmental variables for DKMS
DRV_NAME=rtl8814
DRV_VERSION=4.3.21
#Make directory for driver
mkdir /usr/src/${DRV_NAME}-${DRV_VERSION}
#Clone the git repository
git clone https://github.com/astsam/rtl8812au.git
/usr/src/${DRV_NAME}-${DRV_VERSION}
#Use DKMS to build and install the driver
dkms add -m ${DRV_NAME} -v ${DRV_VERSION}
dkms build -m ${DRV_NAME} -v ${DRV_VERSION}
dkms install -m ${DRV_NAME} -v ${DRV_VERSION}
Note: I don't know if these DKMS steps will work for you since it may
compile the driver for 8812au and not 8814. YMMV.

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
should load the correct module.)
modprobe 8812au

Jason

After spending way too much time attempting to install the Realtek
RTL8814 driver module with DKMS, I took your advice and successfully
built and loaded it with the commands you kindly provided above.
My AMD_X86 system has an Intel 3168NGWG WiFi and BlueTooth PCIe card
installed, so I have been using it. After loading the 8812au module,
WiFi will no longer connect while in CommandLine mode, but when
running in X11 mode, WiFi still works fine with the Intel adapter. I
haven't tried removing the Intel iwiwfi module, as lsmod reported
three items associated with it, and I'm unfamiliar with that sort of
configuration. I suspect removing the Intel iwiwfi module and loading
the 8812au module may overcome that issue.
The new device naming conventions are driving me mad. I can no longer
'ls -l /dev/w*' to list the wireless devices, and don't know where to
find them anymore, although 'find' does help. Unfortunately 'find'
didn't find a second (consecutively numbered) WiFi device, nor did
'ip' nor 'iwconfig'. Of course the new 8812au USB adapter is still
listed in the 'lsusb' output as before loading the new module.
So currently, while I now have the 8812au driver module active, I'm
still unable to use the new Comfast CF-917AC WiFi USB adapter
hardware, and without a device name for it, I'm at a loss to diagnose
the issue further.
Thank you for submitting the Feature Request to have the driver
included in the Debian package repository, and all your very detailed
and assistance.
I'll attach a notes text file (kali_driver.txt) of related information
in the hope you may find it of interest.
Best regards,
Larry
