According to <a href="https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html" rel="nofollow noreferrer">Intel</a>, Intel® Wi-Fi 6 AX200 160MHz device is only guaranteed to work with the kernel version <code>5.1+</code>. (For your information, it works on Ubuntu 18.04.4 LTS with kernel version <code>5.3.0-28</code>.)

What I want to achieve

However, I need to get Intel Wi-Fi 6 AX200 working on Ubuntu 16.04.6 LTS with kernel version <code>4.15.0-88</code>. (The reason is that I need CUDA 10 Toolkit, and the highest version of kernel supported by CUDA 10, as of this post, is <code>4.15</code> according to <a href="https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#system-requirements" rel="nofollow noreferrer">NVIDIA</a>.)

Is there any way to get this work in Ubuntu 16.04.6 with kernel <code>4.15</code>?

What I tried

<ul>
<li>I tried copying the firmware, by following <a href="https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi" rel="nofollow noreferrer">this</a>, but no differnce:

<pre class="lang-bsh prettyprint-override"><code>git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware
cp iwlwifi-*.ucode /lib/firmware
</code></pre></li>
<li>I tried installing the backport driver by following this <a href="https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release" rel="nofollow noreferrer">guide</a> but it gives the following error:

<pre class="lang-bsh prettyprint-override"><code>git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
make defconfig-iwlwifi-public

The Wifi does get detected after reboot. However, Ubuntu freezes just right after trying to connect.

Here are some of the information.
