    WiFi card stopped being detected!

    Yesterday, Some updated on my Ubuntu 20.04 were installed. After installation it asked me to restart. After restart, My WiFi card stopped being detected.


    I'm using Lenovo Ideapad 320, with Ubuntu 20.04.
    Here is the output of sudo lshw -C network:

    Currenly I'm using mobile USB ethernet.
    My Laptop is in dual boot mode, with Ubuntu 20.04 and Windows 10. Wifi perfectly works with windows 10. Right now I'm using it in windows 10. Problem occurs only with Ubuntu 20.04
