Не удается подключиться к Wi-Fi, когда CLOSE на маршрутизатор

5

У меня есть Elitebook 8570w, работающий на ubuntu 16.04, и маршрутизатор ac3200. Теперь у меня самая сложная проблема с этой настройкой: когда я близок к маршрутизатору, я не могу подключиться к нему, но когда я уйду дальше, я могу подключиться. Когда он отключается, он просит меня повторно аутентифицироваться (снова ввести пароль). Эксперимент показал, что я не могу соединиться, когда я нахожусь на расстоянии +6 метров от маршрутизатора. Это также происходит, когда я перемещаю маршрутизатор в другое место (так что это не помеха). Я также включил канал маршрутизатора, и это также не решило проблему (пробовали каналы 1-4-8-11).

Кто-нибудь может понять, что может привести к тому, что мой ноутбук не сможет подключиться, когда рядом с маршрутизатором?

О, и прежде, чем я забуду, проблема не возникает в окнах (загрузка поединка).

Я работал над несколькими случаями, использующими драйвер iwlwifi , где проблемы с подключением помогли, когда SSID был изменен, чтобы исключить пробелы в имени. Я предлагаю вам изменить имя своей сети с GLADOS MAINFRAME на GladosMainframe или GLADOS_MAINFRAME или некоторые из них.

Кроме того, есть несколько вещей, которые вы могли бы попытаться улучшить.

Сначала проверьте настройки маршрутизатора. WPA2-AES является предпочтительным; не WPA и WPA2, а не TKIP. Во-вторых, если ваш маршрутизатор способен к N скоростям, у вас может быть более высокая связь с шириной канала 20 МГц в полосе 2,4 ГГц вместо автоматической 20/40 МГц, хотя это может повлиять на N скоростей. Мне также повезло с фиксированным каналом 1, 6 или 11, а не с автоматическим выбором канала. Кроме того, убедитесь, что маршрутизатор не настроен только на использование N скоростей; auto B, G и N являются предпочтительными. После внесения этих изменений перезагрузите маршрутизатор.

Далее, я рекомендую, чтобы ваш регулирующий домен был установлен явно. Проверьте свое:

sudo iw reg get

Если вы получите 00, это настройка одного размера, возможно, подходит для всех. Найдите здесь: Ссылка Затем установите его временно:

sudo iw reg set IS

Конечно, замените свой код страны, если не Исландию. Установите его навсегда:

gksudo gedit /etc/default/crda

Используйте nano или kate или leafpad, если у вас нет текстового редактора gedit.

Измените последнюю строку следующим образом:

REGDOMAIN=IS

Корректируйте внимательно, сохраните и закройте текстовый редактор.

Затем я установил IPv6 для игнорирования в Network Manager: Ссылка Этот пример для ethernet, но вы хотите беспроводную связь.

Если эти изменения не помогают, попробуйте:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=8

Если это помогает, сделайте его постоянным:

sudo -i
echo "options iwlwifi 11n_disable=8"  >>  /etc/modprobe.d/iwlwifi.conf
exit
