Беспроводная связь отключается каждые 5 минут [дубликат]

Question 1

У меня новый Dell XPS 15 под управлением Ubuntu 17.10. Моя беспроводная связь отключается каждые пять минут, поэтому мне приходится вручную отключать и снова подключаться.

Пожалуйста, помогите мне с этой досадной проблемой.

Question 2

Так как я не могу прокомментировать, я пишу ответ.

Я совершенно уверен, что это - дубликат WiFi, нестабильного после 17,10 обновлений.

Решение состоит в том, чтобы обновить встроенное микропрограммное обеспечение из репозитория, сохраняемого Qualcomm в https://github.com/kvalo/ath10k-firmware.

Question 3

Question 4

Я отключил бы питание Wi-Fi managent и видел бы, как оно работает

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
systemctl restart network-manager.service
