Ubuntu 16.04 Ethernet dejó de funcionar,

Mi Ethernet dejó de funcionar hoy y estoy tratando de descubrir por qué. Creo que podría tener que ver con que el hardware no enruta las cosas correctamente, pero esto se debe simplemente a buscar en Google. Veo que la IRQ en el último comando es 128 pero la interrupción es 16 en ifconfig. No estoy seguro de qué cambió cuando encendí mi computadora portátil hoy en comparación con otros días... Aquí hay algunos resultados:
