I just bought brand new Lenovo ThinkPad T15 Gen 2 20W4000GRT and trying to run fresh downloaded Ubuntu 20.04.3 LTS on it. Everything looks great besides absence of WiFi (Bluetooth has been detected though). I have read all the amount of suggestions regarding this issue other people had, but all of them mostly boil down to update kernel to 5.10+ version. My uname -r reporting me

$ uname -r
5.11.0-27-generic

so I figured out there is something else I missing? Updating drivers by Intel from https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html doesn't help as well.

Here is output of dmesg | grep -i iwl:

$ dmesg | grep -i iwl

And here is $ sudo lshw -c network output:

  • Can you please boot to a Ubuntu Live 21.04 DVD/USB and see if it works there? Report back. – heynnema Aug 28 '21 at 18:58

  • @heynnema thank you for your advice! You were right, 21.04 work great! Seems like 5.11.0-16 kernel fixed it back. Now I have to figure out how to update kernel on another system w/o online connection. – username Aug 29 '21 at 08:13
