I downloaded the Ubuntu 18.04.5 distribution from the official website and installed it on my new Lenovo ThinkPad T15 Gen2 laptop. After installation, it turned out that the settings for LAN are missing in the Network interface

And the Wifi settings indicated that No Wi-Fi adapter Found

lspci | grep -i net

In Ubuntu 18.04 and also 20.04, you get the same symptom:

Direct firmware load xx.ucode failed with error -2

In fact, the referenced firmware files are unavailable anywhere.

This AX210 device is not, according to Intel, supported until kernel versions 5.10 and later: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

Wi-Fi 6E products Intel® Wi-Fi 6E AX210 (5.10)

Ubuntu 21.04 shipped with kernel version 5.11, suggesting full support for your device. My own 21.04 install suggests that the driver iwlwifi supports your device:

chili@T440p:~$ modinfo iwlwifi | grep 2725
alias:          pci:v00008086d00002725sv*sd000000B0bc*sc*i*
alias:          pci:v00008086d00002725sv*sd00006024bc*sc*i*
<snip>
chili@T440p:~$ modinfo iwlwifi | grep ty-a0-gf-a0
firmware:       iwlwifi-ty-a0-gf-a0-59.ucode
chili@T440p:~$ ls /usr/lib/firmware | grep ty-a0-gf-a0
iwlwifi-ty-a0-gf-a0-59.ucode

Therefore, I suggested that you install Ubuntu 21.04 and, after you did, your wireless is working as expected.
