Hello, Since setup many months ago I've been running the router with a scheduled reboot every night at 02:00. Within the latest few weeks, I woke up in the morning to all devices being offline...

@AlfredoGacor Exactly the same problem here, with my C1200 started about some months ago. Hardware version: Archer C1200 v1.0 Firmware version: 1.1.3 Build 20180124 rel.52299 (EU) No updates... 🤦🏼♂️
