7. Risoluzione Dei Problemi
If you encounter issues with your NEWFAST AX1800 WiFi Extender, refer to the following common troubleshooting steps:
7.1. No Internet Access or Weak Signal
- Controlla la potenza: Ensure the extender is properly plugged into a working power outlet.
- Reposition Extender: Move the extender closer to your main router. Use the signal indicator on the device to find a location with a strong signal from the router.
- Verifica la connessione del router: Ensure your main router is functioning correctly and providing internet access.
- Riavvia i dispositivi: Power cycle both your main router and the extender. Unplug them, wait 10 seconds, then plug them back in.
7.2. Cannot Connect to Extender's WiFi
- Check WiFi Name (SSID): Ensure you are selecting the correct extended WiFi network name (SSID), which is typically your main router's SSID with '_EXT' or similar appended.
- Password: Confirm you are entering the correct WiFi password. It is usually the same as your main router's password unless you changed it during setup.
- Reimposta Extender: If issues persist, perform a factory reset on the extender. Locate the reset button (usually a small pinhole) and press it for 5-10 seconds until the lights flash. After resetting, you will need to reconfigure the extender.
7.3. Velocità basse
- Posizionamento dell'estensore: Ensure the extender is not too far from the main router. A weak signal from the router will result in slower extended speeds.
- Interferenza: Minimize interference from other electronic devices (e.g., microwaves, cordless phones) by placing the extender away from them.
- Selezione della banda: For high-bandwidth activities (streaming, gaming), try connecting devices to the 5.8GHz band if available, as it generally offers faster speeds with less congestion.
