I tested whether the WiFi adapter could be connected to a WiFi even with a higher version of Linux, but it failed.
so I reverted linux to the current version and The driver has been rebuilt to the root directory
Like when it was connected before.
However, it has not been connected to wifi ever since the version was restored.
There was a question in a similar situation https://stackoverflow.com/questions/41234080/iwlist-scan-return-no-result-ra0 so I wrote the command to the terminal as root and I tried to restart and try to connect, but it didn't work.
