Не переподключается NetworkManager

Как, впрочем, и любой менеджер подключений. При перезагрузке компьюетра или перевтыкании провода, связь с интернетом пропадает. До этого использовал systemd-networkd, в нём связь появлялась снова при перезапуске всей службы, в NetworkManager достаточно переподключиться в GUI (что характерно, перезапуск службы не восстанавливает связь в его случае). Оставил его.
Пытался решить проблему самыми разными способами - ну вот не хочет подключаться и всё тут.

Вот так status выглядит, когда сеть работает:

Cмотри что есть в resolv.conf , возможно не генерируются DNS .

Пытался и через минуту, и через две и через несколько секунд и сразу после втыкания. Абсолютно индефферентно.

В резолве вот такая громада. К тому же, подключиться не может именно по ip. Были проблемы с http адрессами (а значит - DNS), как починил - хоть убейте, не вспомню.

Torchwood01, ты уже в настройках NM определись, по IPv4 или по IPv6 нужно тебе подключение.
У тебя сейчас по двум протоколам шпарит.

Кажется, и правда в этом проблема. Могу предположить, что два протокола конфликтуют. Потому что когда в resolv сверху ipv6-адреса - всё работает, а когда сверху ipv4 - падает.
Только вот я только что вкрутил NetwokManager принудительный ipv6, а он продолжает пихать ipv4... где не так сделал?

Эти адреса по IPv6 , в настройках соединения смотри вкладку - Параметры IPv6 , ниже в способах настройки выбери - игнорировать и сохрани .
Перечитав лог и перепроверив ещё раз, заметил интересную деталь. Есть момент после перевтыкания, когда resolv.conf не обновлённый и порядок правильный. Я увидел, удивился, набрал cat ещё раз, а он уже поменялся.
