Wi-Fi пропадает в Kubuntu 20.04

У меня проблема, которая сводит меня с ума . Я новичок в мире Linux, стер Win10,перемещен на Kubuntu, и у меня постоянная проблема: в непредсказуемые периоды времени Wi-Fi отключается, любые щелчки по значку Wi-Fi не показывают список сетей вокруг, и может помочь только перезагрузка. У моей жены другой ноутбук на Win10, она подключена к той же точке Wi-Fi, и все в порядке - проблема не в роутере.

KDE Plasma Version: 5.18.5
Версия KDE Frameworks: 5.68.0
Версия Qt: 5.12.8
Версия ядра: 5.4.0-56-generic

Что я пробовал:

  1. Переустановите драйверы для Qualcomm Atheros QCA9377 с Github

  2. Переустановите все пакеты Ubuntu →

     sudo apt-get clean
     

    вставьте ниже в файл install_all.sh

     #! / Bin / bash
    для pkg в dpkg --get-selections |  awk '{print $ 1}' |  egrep -v '(dpkg | apt | mysql | migtv)';  выполните apt-get -y --force-yes install --reinstall $ pkg;  сделанный
    
    sudo chown root: root переустановить_all.sh
    sudo chmod 755 переустановить_all.sh
    sudo ./reinstall_all.sh
     
  3. sudo apt-get install --reinstall bcmwl-kernel-source

    , но у меня та же ошибка, помогите, пожалуйста.
