У меня сбой dhcp, когда я пытаюсь подключиться к моему домашнему Wi-Fi
Я недавно установил xubuntu 18.04 и обнаружил, что не могу подключиться к своему домашнему Wi-Fi. Он просто пытается подключиться к нему в течение 30 секунд, а затем у меня есть значок "нет подключения".
Вот журналы NetworkManager

У меня не было проблем с этой сетью до того, как я установил xubuntu (раньше я запускал windows), и все еще не возникает проблем, когда я подключаю свою домашнюю сеть к другим устройствам
Более того, у меня нет проблем с подключением к другим сетям.
Любая поддержка очень ценится
