Last weekend, several DrayTek routers appeared to be stuck in reboot loops. DrayTek advises disconnecting the WAN and trying to upgrade the firmware, adding that users should “try the TFTP firmware upgrade if the normal upgrade using the WEB UI does not work.” The advice suggests that the issue is due to a vulnerability, though this has not been confirmed. The issue is affecting DrayTek routers around the world. More information here https://faq.draytek.com.au/docs/draytek-routers-rebooting-how-to-solve-this-issue/
