| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | "Integrity check failed" | Corrupt download or wrong hardware version | Redownload from a different source; verify MD5 checksum. | | Router stuck in boot loop | Incompatible firmware or power loss during flash | Attempt TFTP recovery. If that fails, you need serial console recovery (advanced). | | Web UI shows wrong language | Regional mismatch (e.g., Chinese vs. European firmware) | This is cosmetic. Use Google Translate or reflash a correct regional .bin. | | No internet after update | Lost GPON registration or VLAN settings | Factory reset, then manually re-enter your ISP’s WAN settings. | | Wi-Fi missing or weak | EEPROM calibration data overwritten | This is serious. Only a full backup restore or ISP technician can fix it. |
