Public bug reported:
I have a box with 802-11n and I run into a problem with my Lenovo laptop :
- when I change the wifi password, it connects immediately and works well
- the next time (for example after switching the airplane mode on and off), it
fails and the network manager keeps asking me the password again and again
Please notice that I have no problem with other wifi access points (when
going in other places with my laptop), and my box works well with every
other devices (ubuntu laptops, android phones) but mine !
My laptop runs an updated 20.04.4, but the problem first came when I was
on 21.04. I then made a fresh install of 21.10 and then a fresh install
on 20.04 just to make sure the kernel was not involved. Even tried the
last Intel Clear Linux without success.
As a workaround, I tried to stop and restart wpa_supplicant:
sudo systemctl disable --now wpa_supplicant.service
sudo systemctl enable --now wpa_supplicant.service
but this did not solve the problem.
I also contacted the support of my ISP and they made a clear reset of my box
without success.
Here is what I see in dmesg :
