Что текущее состояние Центрино Совершенствуется-N 6235 на Ubuntu?

Question 1

Я работаю, Усик 7 с Ubuntu 17.10 с (к сожалению), идет с Центрино Усовершенствованные-N 6235. Этот беспроводной адаптер не работает очень хорошо, он имеет очень медленное время реакции, и я не могу получить пропускную способность более чем 600 Кбит/с, где другие устройства в той же сети делают легко до 5 МБ/с. Я нашел несколько сообщений, решающих эту проблему:

Intel Centrino Centrino Advanced-N 6235 слабый беспроводной прием

Усовершенствованные-N 6235 Lubuntu 13.10 Intel Corporation Centrino (газуют 24), проблема

Пропускная способность Intel Centrino Advanced-N 6235

Но они стары и главным образом обращаются к старой ошибке Ядра, которая, кажется, несколько зафиксированных годы назад: https://bugs.launchpad.net/ubuntu / + источник/Linux / + ошибка/1159145

Таким образом, я задаюсь вопросом, есть ли у кого-то этот беспроводной адаптер, работающий без проблем. Действительно ли это - аппаратные средства или проблема программного обеспечения, есть ли что-нибудь, что я мог сделать для улучшения соединения?

Вот пример вывода dsmg (я изменил MAC-адрес):

Question 2

отключиться от AP XX: 28: 6d: 30: 13: XX для нового аутентификации на e0: 28: 6d: 30: 13: 4c

Похоже, что у вас есть два идентификатора SSID с одинаковым именем, и ваше устройство перемещается между ними в поисках лучшего соединения. Похоже на мою старую девушку!

Я подозреваю, что это сегменты 2,4 ГГц и 5 ГГц вашего маршрутизатора. Я предлагаю вам переименовать их, чтобы дифференцировать их. Я предлагаю router2.4 и router5 или что-то подобное. После всех изменений, которые я рекомендую, посмотрите, какой сегмент предлагает лучшую скорость, и придерживайтесь ее.

Пожалуйста, проверьте настройки беспроводной сети в маршрутизаторе. WPA2-AES является предпочтительным; не любой WPA и WPA2 смешанный режим и, конечно, не TKIP. Во-вторых, если ваш маршрутизатор поддерживает N скоростей, у вас может быть лучшее соединение с шириной канала 20 МГц в диапазоне 2,4 ГГц вместо автоматических 20/40 МГц, хотя это может повлиять на N скоростей. Мне также больше повезло с фиксированным каналом, 1, 6 или 11, а не с автоматическим выбором канала. Также убедитесь, что маршрутизатор не настроен на использование только N скоростей; auto B, G и N является предпочтительным. После внесения этих изменений перезагрузите маршрутизатор.

Далее, я рекомендую, чтобы ваш регуляторный домен был установлен явно. Проверьте свои:
sudo iw reg get
Если вы получите 00, это настройка «один размер может быть подходит всем». Найдите свой здесь: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Затем временно установите его:
sudo iw reg set IS
Конечно, замените код своей страны, если нет Исландия. Установите его постоянно:
sudo nano /etc/default/crda
Измените последнюю строку на следующую:
REGDOMAIN=IS
Внимательно вычитайте, сохраните и закройте текстовый редактор.

Далее, убедитесь, что у вас установлена последняя версия прошивки; проверьте:
sudo dpkg -s linux-firmware
Мы надеемся, что у вас есть 1.169.3. Если нет, то откройте терминал и выполните:
cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.3_all.deb
sudo dpkg -i linux*.deb
После всех этих изменений перезагрузите маршрутизатор и компьютер и сообщите нам, если есть какие-либо улучшения.
