6. Solució De Problemes
If you encounter issues with your NEXXT router, refer to the following common troubleshooting steps:
- Sense connexió a Internet:
- Comproveu totes les connexions de cable entre el mòdem i l'encaminador, i entre l'encaminador i els vostres dispositius.
- Reinicieu tant el mòdem com el router.
- Verifiqueu que el vostre proveïdor de serveis d'Internet (ISP) no tingui cap problema de sortidatage.
- Velocitat Wi-Fi lenta:
- Assegureu-vos que els vostres dispositius estiguin connectats a la banda Wi-Fi adequada (5 GHz per a velocitats més ràpides, 2.4 GHz per a un abast més ampli).
- Reduïu les interferències allunyant el router d'altres aparells electrònics.
- Limit the number of active devices or bandwidth-intensive activities on your network.
- Consider repositioning the router for better signal coverage.
- Desconnexions freqüents:
- Actualitzeu el firmware del router a la darrera versió.
- Check for conflicting IP addresses on your network.
- Assegureu-vos que el router no s'està sobreescalfant.
- Unexpected Redirects to Ads or Unwanted Pages:
Some users have reported instances where the router redirects invalid or mistyped website addresses to advertising pages, specifically through the
nexxtwifi.comdomain. This behavior is not typical for standard router operation and may indicate an issue with the router's default DNS handling or a potential security vulnerability. If you experience this, consider the following:- Change DNS Settings: Accedir al router web interface (usually 192.168.1.1 or 192.168.0.1) and manually configure the DNS servers to a public, trusted provider like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1). This can bypass the router's default DNS redirection.
- Actualització del firmware: Ensure your router's firmware is up to date. Manufacturers often release updates to address security concerns and improve functionality.
- Restabliment de fàbrica: As a last resort, perform a factory reset on the router. This will revert all settings to their default state. You will need to reconfigure your network from scratch.
- Contacte amb l'assistència: If the issue persists, contact Nexxt Solutions customer support for further assistance.
Note: The provided video demonstrates this specific issue where mistyped URLs are redirected to ad pages via the router's internal DNS handling, specifically through
nexxtwifi.com. This behavior is not expected and should be addressed by changing DNS settings or contacting support.
