Проблема с адаптером USB WiFi

Просто установленная Ubuntu 18.10 сегодня n, я изобразил свой адаптер USB WiFi, не работает. Мой внутренний адаптер не достаточно мощен, чтобы использоваться, так как моя комната довольно далека от маршрутизатора (проблема студента университета). Кто-либо может помочь мне? Я потратил впустую почти 15 часов, уже гуглящих n пытающийся решить эту проблему.Подробнее: Модель: Микросхема Comfast CF-926AC V2.0: MT7612U (я погуглил его n, не уверенный ли его корректное или не),
