The phenomenon is that it tries to connect to 5GHz and then after few
seconds reconnects to the 2.4GHz network.

I send the log enclosed.

Hi Sebastien,
I apologize for the late response. This is my first bug report. Since June I replaced ubuntu 20.04 with Elementary OS (5.1.7 Hera) and the same error occurs here. I am not able to connect to a 5GHz WIFI network. In case I am sending this information to the wrong place, please let me know where I need to report this bug.

Dear You-Sheng Yang,

I installed the i915 firmware, unfortunately it had no effect on WIFI. (I read that this is required for the graphics card.)

How can I set the kernel-bug-existence-upstream tag in your comment above?

Hello,
Today I installed the updates and, in addition to several packages, the wireless-regdb:amd64 (2018.05.09-0ubuntu1~18.04.1, 2020.11.20-0ubuntu1~18.04.1) has been updated too. As a result, my previous connection problem has been fixed.
