Estoy ejecutando Ubuntu 16.04, en asrock Z370M Pro 4 (Giga PHY Intel® I219V).
Mi conexión por cable se interrumpe constantemente, en intervalos aleatorios. Funciona durante 20/30 segundos, hasta un minuto, luego se desconecta durante 20-30 segundos hasta 2 minutos.
A continuación se muestran algunas salidas del terminal:
