WiFi is not working. Not sure how to fix it. I had same WiFi chip on my older PC where it worked by disabling fast boot. I did disable fast boot but no luck. I've done update.

How to fix it?

Some commands and output:

$uname -r
5.11.0-46-generic

$ lsmod | grep iwlwifi
iwlwifi               372736  1 iwlmvm

$ ls /sys/class/net
enp3s0  lo

$cat /etc/netplan/01-network-manager-all.yaml

  • Have you rebooted router, and tried connecting to that same network with other devices? If you are sure it is your OS software, you should be able to bring it up manually with `nmcli`, but I would troubleshoot thoroughly first. [Here](https://askubuntu.com/questions/1356442/ubuntu-20-04-cannot-connect-to-wifi-wifi-settings-not-visible/1356547#1356547) is an older answer of mine w/ `nmcli` usage listed. – Nate T Jan 17 '22 at 00:49
  • Please edit yor question to show the result of the terminal command: `sudo dmesg | grep iwl` – chili555 Jan 17 '22 at 01:06
  • @chili555 I've updated question with sudo dmesg | grep iwl command output – Raymond Jan 17 '22 at 11:09
  • I don't think we need numerous threads covering the same bug and fix - see here: [Intel Wifi 6 AX210 - WiFi not working after Update](https://askubuntu.com/questions/1360175/intel-wifi-6-ax210-wifi-not-working-after-update) – Artur Meinild Jan 21 '22 at 09:36

This command provides greater details around the hardware capabilities of specific adapters.

In the terminal:

sudo lshw -class network
