Интернет-соединение разрывается через 10 секунд

У меня проблема с проводным подключением в Ubuntu 20.04. Когда я перезапускаю проводное соединение, Интернет подключается в течение 10 секунд, а после этого Интернет отключается. Это происходит после подключения к другому Ethernet . Я тестировал в Windows на том же устройстве, и проводное соединение работает отлично.
