Feedback on the Lenovo ThinkPad T16 Gen 2 (202303-31396)

Asked by Anton Parkhomenko

I use Lenovo Thinkpad T16 Gen 2 (Type Number 21HH-0029FR) with Ubuntu 22.04

anton@thinkpad-e15:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy

When I connected to network using Wi-Fi laptop can stuck without any response to network, dmesg, journalct, etc
I even can't reboot ot shutdown it gracefully, so I have to shutdown it with Power button pressed for 10 seconds

I mostly use wire connection, but when on Wi-Fi it's a real trouble
