• Nessuna connessione internet:
  • Check all cable connections (coaxial, power, Ethernet) to ensure they are secure.
  • Verify the Online LED is solid green or blue. If blinking or off, contact your ISP as there might be a service outage or activation issue.
  • Reboot the modem by unplugging it from power for 30 seconds, then plugging it back in. Wait for all LEDs to stabilize.
• Velocità Internet lente:
  • Ensure your devices are connected to the 5GHz Wi-Fi band for faster speeds, if supported.
  • Verificare la presenza di interferenze da parte di altri dispositivi elettronici o reti Wi-Fi vicine.
  • Perform a speed test (e.g., via speedtest.net) to confirm actual speeds. If significantly lower than your plan, contact your ISP.
  • Verify your ISP's line signal quality. Poor signal quality can lead to reduced performance and modem overheating.
• Problemi di connettività Wi-Fi:
  • Ensure the Wi-Fi LED is solid green.
  • Check your Wi-Fi password and network name (SSID).
  • Prova a dimenticare la rete sul tuo dispositivo e a riconnetterti.
  • If many devices are connected, consider reducing the number or upgrading your internet plan.
• Accesso Web Interfaccia:
  • Se non riesci ad accedere al web interfaccia a http://192.168.0.1, ensure your device is connected to the modem.
  • If you changed the firewall setting to "MEDIUM" or higher, you might need to use https://192.168.0.1 and accept security warnings.
