6. Solución de problemas
- Sin LED de encendido: Ensure the power adapter is securely connected to the adapter and a working electrical outlet.
- No MoCA LED: Verify that coaxial cables are securely connected to both adapters and the wall outlets. Ensure your coaxial network is MoCA-compatible (not compatible with Directv, Dish Network, AT&T U-Verse, or other non-MoCA compliant subscription services).
- No LAN LED: Check the Ethernet cable connection between the MoCA adapter and your network device/router. Try a different Ethernet cable if necessary.
- Velocidades lentas: Ensure all connections are tight. Check for any splitters in your coaxial line that might degrade the signal. Consider using MoCA-compatible splitters if multiple devices share the coaxial line.
- Conexión intermitente: Ensure there are no loose cables. Power cycle both MoCA adapters and your router.
