Wi-Fi смешно замедляет работу Ubuntu 16.04 LTS и Frontier MI424WR Router

Question 1

Мой Acer Aspire E5 575G имеет Qualcomm Atheros QCA9377. Я попытался переустановить мое ядро, я переустановил драйверы (ath10k), установил backport, отключил режим энергосбережения, установил wicd и т. Д. Единственное, что немного помогло - это отключить WMM в настройках маршрутизатора. Моя версия ядра 4.10.0-42-generic. Типичные скорости рядом с маршрутизатором - 15 Мбит / с вверх и вниз. У меня план 50/50. 50 Мбит / с - это скорость моего Ethernet. когда bluetooth включен, мои mbps составляют половину текущего медленного Wi-Fi. Вот некоторые из команд, которые вы часто задаете:
