Router WAN disconnections and reboots

Expired

We have received reports of DrayTek routers disconnecting unexpectedly.

If you are experiencing this issue, then it is possible that the router is repeatedly rebooting which is why the WAN connection keeps disconnecting and attempts to log into the router’s Web UI are timing out. A possible cause for this on older models is related to SSL VPN and Remote Management. Please follow the steps below to troubleshoot as this should resolve the issue:

  1. Disconnect the WAN cable.
  2. Log into the router’s Web User Interface and check the system uptime. The router’s default IP Address is https://192.168.1.1 but may have been changed to a different IP Address when it was originally setup. At this time the password will also been set by the system administrator. This guide explains how to log into the router If the uptime is lower than the last known reboot, this indicates the router recently restarted.
  3. Disable Remote Management by going to [System Maintenance] > [Remote Management]. Disable remote management
  4. Disable SSL VPN Service by going to [VPN and Remote Access] > [Remote Access Control]. Disable SSL VPN
  5. Reboot the router and reconnect the WAN cable.
  6. Monitor the connection to see if the WAN remains stable.

Firmware check and update:

  • Verify your router’s firmware version. If it is outdated, update it to the latest version
  • Before updating, note your current firmware version. If you do not have a copy of the current firmware, download it first.
  • Take a configuration backup to avoid losing your settings.

If your WAN connection is stable:

  • Even if your device is not disconnecting, it is good practice to ensure you are on the latest firmware.
  • If your router is already on recent firmware and the newest version is not marked as Critical, an update may not be urgent but is still recommended for optimal performance and security.

Remote Management:

  • If remote management is required then only enable this if you are using an ACL
