| Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | | Corrupted firmware upload or power loss during flashing | Perform a factory reset (hold reset button for 10 seconds using a paperclip). If unreachable, use TFTP recovery method (see manual). | | Web interface shows "Upgrade failed" | File integrity mismatch or wrong hardware revision | Redownload the firmware. Ensure you have the "H" variant (GW020-H) and not the "E" or "S" model. | | Wi-Fi drops intermittently post-update | New firmware resets default wireless region or channel | Reconfigure 2.4GHz/5GHz settings. Try fixing channel width to 20MHz for legacy devices. | | Modbus RTU no longer responds | New firmware changed UART buffer timing | Increase Response Timeout from 200ms to 500ms in Protocol Settings. Downgrade only as last resort. | | Login credentials not accepted after update | Firmware enforced stronger default password | Check release notes for new default (e.g., admin / gateway123 ). If locked out, use hardware reset button. | Igate Gw020-h Firmware
