Это кажется действительно сумасшедшим, и я обнаружил корреляцию только случайно. И все же теперь я проверял это бесчисленное количество раз: когда мой Fire TV подключен к источнику питания (даже если он находится в режиме ожидания), моя система Ubuntu 16.04 LTS не может подключиться к WiFi-маршрутизатору. В частности, появляется диалоговое окно с графическим интерфейсом:
Требуется аутентификация в сети Wi-Fi
Хотя пароль определенно правильный и сохранен (и работает, как только я отключаю Fire TV).
Как только система Ubuntu будет подключена, я снова смогу подключить Fire TV, и оба будут работать с подключенным WiFi.
У меня действительно нет идей, как анализировать или решать это, и это раздражает. Я искал в Интернете, но не нашел ничего связанного. Это вывод моего соответствующего /var/log/syslog:
