According to Intel, Intel® Wi-Fi 6 AX200 160MHz device is only guaranteed to work with the kernel version 5.1+. (For your information, it works on Ubuntu 18.04.4 LTS with kernel version 5.3.0-28.)

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 4.15.0-88. (The reason is that I need CUDA 10 Toolkit, and the highest version of kernel supported by CUDA 10, as of this post, is 4.15 according to NVIDIA.)

Is there any way to get this work in Ubuntu 16.04.6 with kernel 4.15?

What I tried

  • I tried copying the firmware, by following this, but no differnce:

    git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware
cp iwlwifi-*.ucode /lib/firmware

  • I tried installing the backport driver by following this guide but it gives the following error:

    git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install
...
...
At main.c:160:
- SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175
- SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:178
sign-file: certs/signing_key.pem: No such file or directory
...

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

    Here are some of the information.

Notes

  • In a similar post, the provided answer is to upgrade the kernel to 5.1+, which doesn't meet the requirement in my case.

  • Please see: https://github.com/umlaeute/v4l2loopback/issues/139 "afaict, the error is unrelated and not harmful: during make install the system also tries to sign the module, and since you do not have the required keys to sign, this fails. nevertheless the make install succeeds, and you should be able the module." Can you load the module? sudo modprobe iwlwifi Did the backports version actually install? modinfo iwlwifi | grep file Are there any clues in the message log? dmesg | grep iwl Or here? rfkill list all – chili555 Mar 17 '20 at 20:48
  • @chili555 , Thanks for taking a look. I proceeded as you suggested but Ubuntu freezes right after trying to connect to WiFi. I edited my question, adding results as requested. – IgNite Mar 18 '20 at 00:52
  • Are there any clues here? cat /var/log/syslog | grep -e iwl -e wlp | tail -n 15 Please try: sudo modprobe -r iwlwifi && sudo modprobe iwlwifi disable_11ax=y Now try to connect. Does it still freeze? – chili555 Mar 18 '20 at 01:35
  • No luck; it still freezes. (I added the result of /var/log/syslog/ in my question. But I think the message is not relevant, because the time in the message was 07:54, but the most recent time when I tried to connect the WiFi was ~08:30.) – IgNite Mar 18 '20 at 01:54
  • I think I found another approach, but I have completely no idea how it is different: install backport-iwlwifi-dkms from this repository. – IgNite Mar 18 '20 at 01:58
  • The driver itself is no different at all. ‘dkms’ means that the driver needn’t be re-compiled and reinstalled after every kernel update. – chili555 Mar 18 '20 at 02:23
  • The log suggests that iwlwifi is not the cause of the freeze. – chili555 Mar 18 '20 at 02:25
  • @chili555, Sorry for not getting back for a while. I was fixing a famous Nvidia driver login loop. So, I tried again and I updated /var/log/syslog in my question. – IgNite Mar 19 '20 at 15:02
  • Again, we nothing related to the driver iwlwifi that suggests a crash or freeze. You might also check: grep etwork /var/log/syslog to see if Network Manager has any clues. As the output will be lengthy, post the result here and give us the link: http://paste.ubuntu.com – chili555 Mar 19 '20 at 15:35

I have completely no idea how this repository is different from the official backport driver from Intel. But it does work on my laptop.

sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi
sudo apt-get update
sudo apt-get install backport-iwlwifi-dkms

Only for ubuntu 16.04 lts checked

  1. Check kernel version uname -a if version no 4.15 update to 4.15 sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04 If update kernel need reboot

  2. Just copy and paste

git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
sudo make defconfig-iwlwifi-public;sudo make; sudo make install
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware/
sudo cp iwlwifi-* /lib/firmware/
reboot

  • Hi, perhaps you could be more elaborate about what the commands will do, so others can learn/understand what is done here ;) – d1bro Mar 08 '21 at 22:51
