We are experiencing a serious stability issue with the ER8411.

The router randomly freezes during normal operation. When the issue occurs, the entire network goes down, VPN connections are disconnected, the Omada Controller loses access to the router, and the local management page becomes unreachable. The device does not recover by itself. The only way to restore service is to physically power-cycle the ER8411.

This is not a minor connection issue or a simple controller disconnection. It is a complete router hang that causes a full network outage and directly affects business operations.

We have also found similar reports from other users, so this appears to be a known stability problem rather than an isolated case. TP-Link should formally investigate this issue, identify the root cause, and provide a reliable fix through firmware update, hardware revision, or replacement program if necessary.

Please escalate this issue to the engineering team and provide an official corrective action plan.
