Intel AX200 - How to enable Wifi?
Environment:
Motherboard: X570 AORUS ULTRA CPU: AMD Ryzen 9 3950X 16-Core Processor Distro: Ubuntu server + xfce4 Ubuntu version: 21.04 Kernel version: 5.11.0-17-generic Wifi hardware: Intel Corporation Wi-Fi 6 AX200 [8086:2723] (rev 1a) Boot: Single boot (No Windows. Just Ubuntu). Fast book disabled in bios.This is a clean install. No issues during install.
The problem I am running into is that, although the OS detects the hardware, the link seems to be DOWN.
$ ip a
3: wlp6s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noqueue state DOWN group default qlen 1000 link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ffThere are many similar messages on the net:
Intel Wi-fi 6 AX200 adapter not found on Ubuntu 20.04
Cannot get an Intel Corporation Wi-Fi 6 AX200 (rev 1a) to work with Mate 20.04
Will intel Wifi AX200 work with ubuntu 20.4 in WIFI 6 mode
However, I already have incorporated all the recommendations:
- Disabled fast boot in bios
- No dual boot
- Have the latest x570 bios firmware
- Have a newer Linux kernel
- Have the latest Intel AX200 wifi driver (/lib/firmware/iwlwifi-cc-a0-59.ucode)
I still cannot figure out how to get the wifi to work. Please help.
Here is some useful info:

By default, Ubuntu server edition does not include the required packages wpa_supplicant and wireless-tools. To install them, with a temporary working internet connection by tethering, ethernet or whatever means possible, do:
sudo apt update
sudo apt install wpasupplicant wireless-toolsSeveral dependencies will also be installed.
Next, edit your netplan file to add your exact details. For servers, I recommend a static IP address so that you can easily SSH and FTP into it. Please be certain to select an address outside the DHCP pool in the router.
Next, remove your not-working netplan file:
sudo rm /etc/netplan/*.yamlAnd create a new file.
sudo nano /etc/netplan/01-netcfg.yamlI suggest:
network: version: 2 renderer: networkd wifis: wlp6s0: dhcp4: no dhcp6: no addresses: [192.168.0.150/24] gateway4: 192.168.0.1 nameservers: addresses: [192.168.0.1, 8.8.8.8] access-points: "network_ssid_name": password: "**********"Of course, substitute your exact details here.
Please note that the network SSID name and the password are enclosed in quotes. Netplan is very specific about spacing and indentation. It accepts spaces but not tabs. Proofread carefully twice. Save (Ctrl+O followed by Enter) and exit (Ctrl+X followed by Enter) the nano text editor.
Follow with:
sudo netplan generate
sudo netplan apply If there are no mistakes, you should connect immediately and automatically on boot.
For me, this solved the issue (cited from the source below):
# run this to determine which firmware the kernal is looking for
modinfo iwlwifi | grep iwlwifi-cc
# example output:
# firmware: iwlwifi-cc-a0-50.ucode
# go and download the firmware
# copy file to /lib/firmware
sudo cp ~/Download/iwlwifi-cc-a0-50.ucode /lib/firmware
# reboot
sudo reboot
# check that firmware was loaded
sudo dmesg | grep iwlwifi | grep version
# example output
# [ 4.566709] iwlwifi 0000:05:00.0: loaded firmware version 50.3e391d3e.0 op_mode iwlmvm
