@Sunshine The firmware version is 1.2.3. The issue started after the firmware update. I haven't tried going back to a previous version or upgrading to a beta one. The only bug is the router...

@BVW9876 I'm having the same issue. Random reboots. Seems related to the number of devices, having around 15-20. If I have visits it happens in a few minutes and I gotta disconnect other devices.
