AX210 WiFi adapter doesn't work on Ubuntu 20.04.3 LTS, kernel 5.11.0-27

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 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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
