Всем привет. Есть такая проблема , при работе происходят отвалы в сети каждые 30 минут. На Linux Mint 18.04 такой проблемы не было, устройства на Windows работают нормально.
ОС - Linux Mint 20 Cinnamon
Cinnamon version - 4.6.7
Ядро - 5.4.0-65-generic

DHCP не может обновить адрес, после чего NM делает полное переподключение интерфейса - это помогает. 30 минут - это период аренды адреса, который выдает сервер.
Это все, что могу сказать на основе таких куцых данных.

На сервере время аренды стоит 1 час

Linux Mint 18.04 такой проблемы не было

Как и версии такой не было. 18.3 была. Дальше 19 идёт.

Activation: failed for connection 'Ethernet connection 2'

У вас несколько сетевых плат или так соединение обозвано? Странно, на шнурке вообще проблем быть не должно. А если статический адрес назначить, будет пропадать сеть?
