We have seen a significant reduction in the number of circuits with symptoms, but there are still a significant number which need attention. DrayTek's advice and statement reads:

<-- snip -->

We have received reports of DrayTek routers disconnecting unexpectedly.

If you are experiencing this issue, please follow the steps below to troubleshoot:

- Disconnect the WAN cable.
- Log into the router’s Web UI and check the system uptime. If the uptime is lower than the last known reboot, this indicates the router recently restarted.
- Disable Remote Management by going to [System Maintenance] > [Remote Management].
- Disable SSL VPN Service by going to [VPN and Remote Access] > [Remote Access Control].
- Reboot the router and reconnect the WAN cable.
- 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 If it is outdated, update it to the latest version.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.

Identified [23/03/2025 09:55]

Since 21:30 yesterday evening we have witnessed an unusually high volume of session drops, primarily impacting BT Wholesale and TalkTalk broadband sessions. The cause has been narrowed down to vulnerable firmware versions on Draytek routers.

If you are seeing broadband circuits exhibiting repeat short sessions, please upgrade the firmware to the latest version.

Likewise, if you are also using Draytek routers to support any Leased Lines, please also review the firmware version before undertaking any further trouble shooting.
