Wi-Fi продолжает отключаться (Ubuntu 20.04)

У меня есть машина с двойной загрузкой Windows 10 и Ubuntu 20.04. Я могу нормально подключиться к Wi-Fi в Windows, но при использовании Ubuntu он отключается каждые 10-20 минут или около того. Когда это происходит, я всегда могу заставить его снова работать:

sudo rmmod wl
sudo modprobe wl

Я пробовал предложения из похожих сообщений (например, отключение IPv6, установка REGDOMAIN = GB в / etc / default / crda и установка linux-прошивки ), но пока ничего не работает. Буду очень признателен, если кто-нибудь сможет помочь.

Вывод из lspci -nn -d 14e4:
