Как отлаживать повторные отключения Wi-Fi в Arch Linux?

После долгого времени, чтобы получить беспроводное соединение , я теперь могу получить чрезвычайно отрывочный (как через несколько секунд фактического доступа в Интернет каждые несколько минут). Запуск wpa_supplicant -d -i wlp0s29f7u5 -c wifi.conf -Dwext в одном VT и while ! yes | pacman -Syu; do :; done while ! yes | pacman -Syu; do :; done в другой, через несколько минут это еще не сделано, но время от времени ему удается загрузить несколько файлов.

iw dev wlp0s29f7u5 link на аппарате Arch сообщает о мощности сигнала около -40 дБ, что намного хуже, чем у соседнего ноутбука Ubuntu при -70 дБ.

Выход подключения:

Любые идеи, что может быть неправильным? Вывод в основном греческий для меня.

Нужно ли мне делать что-либо еще в фоновом режиме, например, возобновить аренду DHCP, когда соединение установлено, чтобы использовать его как можно скорее?

И, наконец, составляет -40 дБ, считается «приемлемым» качеством линии?

Обновление : В dmesg теперь у меня есть огромное количество таких вещей:

Здесь есть несколько странных вещей:

  • Что такое «поврежденный маяк и ответ зонда» и как его исправить?
  • Почему он думает, что я в Польше, когда я в Великобритании?
  • Почему первые три попытки подключения всегда тайм-аут, в то время как четвертый преуспевает?

Проблема заключается в ваших настройках wpa_supplicant; first -Dwext старый. использовать -Dnl80211 секунд; не добавляйте ничего, кроме net.lo и net.wlp0s29f7u5, в свой первоначальный скрипт и добавляйте их во время загрузки для загрузки. в третьих; удалите что-нибудь вроде NetworkManager или Wicd 4th; Очистите сетевой файл и config_wlp0s29f7u5 = "dhcp". это будет полезно, если вы используете dhcp в своем WIFI-соединении. также в вашем терминале с супер-доступным типом доступа dhcpcd . просто для удовольствия; это может решить вам много боли
