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

sudo modprobe iwlwifi && sudo dmesg | grep iwl

  • Please see: https://askubuntu.com/questions/1335033/ubuntu-doesnt-recognize-wifi-on-asus-rog-strix-z590-e-motherboard I recommend that you install 21.04 and check again: sudo dmesg | grep iwl – chili555 Aug 18 '21 at 21:16
  • @chili555 You may wish to point OP to https://askubuntu.com/questions/1356118/ax210-wifi-not-working-on-ubuntu21-04/1356136#1356136 or https://askubuntu.com/questions/1352653/intel-ax201-wi-fi-6-is-not-working-on-ubuntu-21-04/1353300#1353300. OP has a firmware problem too. – heynnema Aug 18 '21 at 21:47
  • @heynnema I'm not quite sure it's the same problem. We don't see any "No config found..." here. Let's see what 21.04 brings us. – chili555 Aug 18 '21 at 22:00
  • @chili555 I think OP's machine has an Intel AX210. Also isn't finding the right firmware. I think that for a short time, some earlier versions of Ubuntu DID find the AX210. – heynnema Aug 18 '21 at 22:04
  • @heynnema Correct. In my 21.04 machine, -59-ucode is called for in modinfo iwlwifi and -59.ucode is present in /usr/lib/firmware. So, fingers crossed. Sorry, OP, we often have these little side discussions! – chili555 Aug 18 '21 at 22:26
  • @chili555 OP's iwlwifi is looking for -39 to -50. Suspect they need linux-firmware or Intel firmware files. – heynnema Aug 18 '21 at 22:29
  • Let us continue this discussion in chat. – chili555 Aug 18 '21 at 22:34
  • Thank you guys for the advice. I will try to install 20.1 and write the results – Jekson Aug 19 '21 at 06:57
  • Guys, good news. Installing version 21.04 seems to have solved all the problems. Thank you so much! Am I correct in assuming that all future versions of the system will have the drivers I need and I don't have to worry about upgrading? – Jekson Aug 19 '21 at 12:01
  • @chili555 Note the OP's last comment. – heynnema Aug 19 '21 at 13:32
  • I shall propose an answer that I hope you will accept: https://askubuntu.com/tour This will be useful to searchers with the same problem. Thanks. – chili555 Aug 19 '21 at 15:27
  • All future versions should work perfectly. I'm very glad it's working! – chili555 Aug 19 '21 at 15:59

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.
