Wi-Fi пропадает (не отключается) при больших загрузках Ubuntu 18.04

Я просмотрел кучу решений, но, похоже, ничего не решило мою проблему.

Мой Wi-Fi отключается (не отключается) при загрузке больших файлов с использованием любого Программный ключ - это Belkin N300 (F9L1002v1) с выключенным режимом энергосбережения. Это не маршрутизатор. Обычно мне приходится отключать и снова подключать ключ, чтобы он снова начал работать.
