Thank you for the bug report and the details, you would probably have a better chance to get a reply reporting directly upstream for network manager since that component currently doesn't have a dedicated maintainer in Ubuntu and is dealt with on best effort basis

With the latest stable 5.4 kernel on Ubuntu Focal 20.04 I cannot get the card to connect to my home wifi (2.4ghz). The errors I get are : iwlwifi 0000:05:00.0: No beacon heard and the time event is over already... wlp5s0: Connection to AP 30:b5:c2:75:a4:ce lost wlp5s0: send auth to 30:b5:c2:75:a4:ce (try 2/3) Initially I thought this could be due to a problem with the iwlwifi driver and the firmware used. I upgraded to a custom-build (using ubuntu's configuration) 5.10 kernel And now the errors I was getting were: [нд яну 17 22:01:33 2021] iwlwifi 0000:05:00.0: No beacon heard and the session protection is over already... [нд яну 17 22:01:33 2021] wlp5s0: Connection to AP 30:b5:c2:75:a4:ce lost [нд яну 17 22:01:33 2021] wlp5s0: send auth to 30:b5:c2:75:a4:ce (try 3/3) [нд яну 17 22:01:34 2021] wlp5s0: authentication with 30:b5:c2:75:a4:ce timed out [нд яну 17 22:01:35 2021] wlp5s0: authenticate with 30:b5:c2:75:a4:ce [нд яну 17 22:01:35 2021] wlp5s0: send auth to 30:b5:c2:75:a4:ce (try 1/3) [нд яну 17 22:01:36 2021] iwlwifi 0000:05:00.0: No beacon heard and the session protection is over already...

At this point I was willing to accept this is an issue with the kernel. However, I added the following configuration to /etc/network/interfaces: allow-hotplug wlp5s0 iface wlp5s0 inet dhcp wpa-ssid HOME wpa-psk <REDACTED> wpa-debug-level 2 And what do you know - I was able to connect to my home wifi with no problems. I'm attaching the output of wpa_supplicant run with -dd from both the /etc/network/interfaces-based configuration (wpa_supplicant_working) and from the NetworkManager managed one ( I have edited /lib/systemd/system/wpa_supplicant.service to include -f /var/log/wpa_supplicant -dd) options. I wasn't able to figure any glaring differences between the flows of the two.
