Ноутбук: Lenovo G50-45

Процессор: Процессор AMD E1

Wi-Fi: Встроенный Qualcomm Atheros в Wi-Fi.

ОС: Ubuntu 16.10

Проблема: Сохраняет подключение к беспроводному маршрутизатору, однако интернет перестает работать.

Обходной путь

1. Отключение от моего Wi-Fi

2. Повторное подключение

Работает еще 5 минут, а затем я должен повторить вышеописанные шаги.
