Использую ОС Ubuntu 18.04. Материнская плата - GIGABYTE Q370M D3H GSM PLUS. Дополнительный сетевой адаптер - Intel I210-T1.
Сразу после установки системы отсутствовала возможность выйти в интернет.
Команда ip addr возвращает:

Если в настройках адаптера задать автоматическое получение адреса то формируется следующий лог (tail -f var/log/syslog):

При этом, компьютер видится в сети и его можно пропинговать, а со стороны хоста пингуются только локальные компьютеры. Роутер 192.168.88.1 пингануться не может.
Пробовал перезапускать различные службы, но результата не дало.
"sudo service networking restart"
"sudo systemctl restart networking.service"
"sudo systemctl restart NetworkManager"
"sudo nmcli networking off && nmcli networking on"
"sudo ifdown -a && ifup -a"
Прошу уточнить, в чем может быть проблема
