Ubuntu 17.04 Переключение на проблему DNS-сервера

Question

Я пользуюсь Ubuntu 17.04 несколько месяцев и у меня не было проблем. Однажды я прибыл во Флориду и начал использовать провайдера Spectrum Communications. Спорадически в то время как на WIFI я начал получать эти строки журнала в /var /log /syslog. Это приводит к тому, что соединение WIFI становится совершенно непригодным для использования. Я провел некоторые исследования и начал использовать Googles DNS, но, похоже, проблема не в том, какой DNS-сервер вы используете. Я также пытался отключить DNSSEC, но это, похоже, тоже не решает проблему. Мне любопытно посмотреть, если это проблема конфигурации или я должен позвонить своему провайдеру для устранения неполадок с ними. Другие машины в доме работают нормально, но они не используют Ubuntu 17.04.

Answer 1

Здесь может быть несколько разных проблем, проблема DNS/DNSSEC [systemd-resolved] и NetworkManager. Некоторые люди сообщают об отключении DNSSEC в systemd-resolved works, другие переключаются на «unbound» для своего решателя-заглушки. Переход на несвязанный в одиночку для меня не решил проблему.

http://www.hecticgeek.com/2017/04/ubuntu-17-04-systemd-dns-issues/

Тем не менее, добавление этого исправления для NetworkManager (и все еще работающего с unbound), похоже, сделало это. На самом деле, скорость сети просто прошла через крышу.

https://askubuntu.com/questions/905997/serious-wi-fi-network-issue-on-ubuntu-17-04

отредактируйте файл /etc/NetworkManager/NetworkManager.conf

И отключите scan-rand-mac-address в разделе [device] :

[device]
wifi.scan-rand-mac-address=no

Я не долго работал с двумя вышеупомянутыми исправлениями, но достаточно долго я решал эту проблему до изменений.
