Ubuntu WiFi является чрезвычайно медленным и разъединяет каждые несколько минут
Я смотрел на различные сообщения для выяснения, почему Wi-Fi является настолько медленным, но напрасно.
Я установил Ubuntu 16.04 просто позавчера и имею двойную загрузку с Windows 10. Windows 10 дает мне нормальную скорость, но когда я пытаюсь войти в систему через Ubuntu, я не могу получить скорость больше чем 40/50 КБ. Я присоединяю вывод сценариев Беспроводной информации ниже и был бы рад предоставить любую другую необходимую информацию.Спасибо.

У Вас есть два возможно конфликтующих загруженные драйвера. Давайте поместим в черный список один и посмотрим, помогает ли это. От терминала:
sudo -i
echo "blacklist rtl8192cu" >> /etc/modprobe.d/blacklist.conf
modprobe -r rtl8192cu
exit
Какое-либо улучшение? Это могло бы взять перезагрузку.
Теперь, проверьте настройки в маршрутизатор. WPA2-AES предпочтены; не любой WPA и WPA2 смешали режим и конечно не TKIP. Во-вторых, если Ваш маршрутизатор способен к скоростям N, у Вас может быть лучшая возможность соединения с шириной канала 20 МГц в полосе на 2,4 ГГц вместо автоматических 20/40 МГц, хотя это, вероятно, будет влиять на скорости N. У меня также есть лучшая удача с фиксированным каналом, или 1, 6 или 11, а не автоматический выбор канала. Кроме того, убедитесь, что маршрутизатор не установлен использовать скорости N только; автоматический B, G и N предпочтены. После внесения этих изменений перезагрузите маршрутизатор.
Затем, я рекомендую, чтобы Ваш регулирующий домен был установлен явно. Проверьте Ваш:
sudo iw reg get
, Если Вы добираетесь 00, который является установкой one-size-maybe-fits-all. Найдите Ваш здесь: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Затем устанавливает его временно:
sudo iw reg set IS
, Конечно, замените своим кодом страны если не Исландия. Установите его постоянно:
gksudo gedit /etc/default/crda
нано Использования или kate или leafpad, если у Вас нет текстового редактора gedit.
Изменение последняя строка, которая будет читать:
REGDOMAIN=IS
Корректируемый тщательно, сохраните и закройте текстовый редактор.
