Algo está matando mi networking cableada, ¿qué podría ser eso?

Estoy usando Fedora 26 x64 y por alguna razón, y random, la networking cableada está siendo destruida por algo. Lo sé porque estoy viendo el post que dice que la networking cableada ya no existe y estoy viendo cómo WiFi se está conectando automáticamente. Intenté reiniciar el service ejecutando:

$ sudo service network restart [sudo] password for rperez: Restarting network (via systemctl): Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details. [FAILED] 

Pero como pueden ver, falla. Los loggings de journalctl -xe muestran lo siguiente:

 $ journalctl -xe -- Subject: Unit fprintd.service has begun start-up -- Defined-By: systemd -- Support: https://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit fprintd.service has begun starting up.

¿Qué está matando mi networking cableada o por qué está siendo asesinado?
