Re: Driver/firmware for Realtek RTL8814U WiFi USB Adapter?

[Jason Wittlin-Cohen <jwittlincohen@gmail.com>]

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.

Which Debian Stretch package provides firmware for the Realtek

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

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:

nor here: https://wireless.wiki.kernel.org/en/users/drivers
