Public bug reported:
My computer has an built-in intel ax200 adapter (the motherboard is
asock taichi x570). 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...

The change of message is because newer versions of the driver/firmware have
moved part of the processing in firmware. 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.
