Hi, i was able to set up wifi 6 suport for intel ax200 in jetson nano using the backport of wifi instaling it from the repository and adding the microdode:
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git
cd linux-firmware
sudo cp iwlwifi-cc-*.ucode /lib/firmware
cd ..
sudo rm -r linux-firmware
sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi
sudo apt-get update
sudo apt install backport-iwlwifi-dkms
But on boot, the wifi connecion take at least 3 minutes to start. Any ideas?
