Wi-Fi на Ubuntu 19.04 безумно медленный по сравнению с Windows 10

Я только что установил Ubuntu 19.04 на раздел на своем жестком диске, и у меня двойная загрузка с Windows 10. Я провел тесты скорости интернета в обеих операционных системах и получил скорость загрузки 104 Мбит / с в Windows 10. Ubuntu (версия 19.04) Я получаю только 4 Мбит / с. Я не уверен, что это проблема с драйверами или ошибка с самой Ubuntu. Помогите мне, пожалуйста!
