| Problem | Solution | |---------|----------| | “File is incorrect” | You are using wrong region/hardware version. | | Router stuck with power LED blinking | Firmware corrupted → use Emergency Recovery above. | | No internet after upgrade | Reset to defaults + re-enter ISP settings (VPI/VCI: 0/35 for most DSL). | | Wi-Fi disappears | After upgrade, Wi-Fi may be disabled by default → re-enable in Setup → Wireless. | | Cannot access 192.168.1.1 | Check LAN cable, disable PC firewall temporarily, try 192.168.0.1 (rare). |

Understanding the internals of the C1 revision is critical for firmware compatibility.
