I have Ubuntu 18.04 in my PC together with Windows 10. When the WiFi works on Windows and I restart the computer to Ubuntu, the WiFi is OK even in Ubuntu. But when the computer is shuted down and I start with Ubuntu, there is apparently no way to start the WiFi. Can someone help me to make the WiFi available in Ubuntu directly?
I typed inxi -F as recommended in comments and the result is as follows:

Further I opened the "Show applications" and typed wifi and they say me I have "no wifi adapter found". So I restarted and opened Windows, the wifi started to work. I restarted again and opened Ubuntu and I have a good wifi. If I turn it off, I can "no more connect because "no wifi adapter found". Can someone explain me how I can install the right wifi adapter. I seen a lot of posts here and Ubuntu documentation, and don't know what is the right procedure.
The kernel version is Linux 5.3.0-28-generic I understand that I need some WiFi adapter congruent with Card-2: Intel Wireless 8265 / 8275 driver: iwlwifi
Update following the advise of @pilot6. I typed when the wifi doesn't work
