Some users have expressed a desire to use the Killer AX1650 in Debian-based Linux. If your version of Linux does not support the Killer Wireless AX1650 at install, and you are using Ubuntu 16.04 or later, or another version of Debian Linux, you can use this guide to backport the drivers from the latest version of Ubuntu/Debian, enabling the Killer AX1650 in 16.04 or later. We have confirmed that this will result in wireless connectivity in Ubuntu 16.04 with the Killer Wireless AX1650.
Type or copy and paste the following commands in a terminal, one line at a time, pressing Enter after each command.
$ sudo apt-get install git
$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
$ cd backport-iwlwifi
$ make defconfig-iwlwifi-public
**NOTE: At this time, a patch needs to be made for the driver to load. This patch has been
upstreamed and should be available in the backport/base iwlwifi module source soon.
Apply patch: https://patchwork.kernel.org/patch/10940911/
$ make -j4
$ sudo make install
Additionally, you will need to ensure you have the latest iwlwifi firmware:
$ sudo git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
$ cd linux-firmware
$ sudo cp iwlwifi-* /lib/firmware/
Once you have done this, you should be able to connect to your wireless access point.
