6. Údržba

To ensure optimal performance and longevity of your Cudy PE25 network adapter, consider the following maintenance tips:

• Aktualizace ovladačů: Regularly check the official Cudy or Realtek website for the latest drivers. Keeping drivers updated can improve stability, performance, and compatibility.
• Fyzická kontrola: Periodically inspect the adapter for dust accumulation, especially around the PCIe contacts and the RJ45 port. Use compressed air to gently clean if necessary.
• Bezpečné sezení: Ensure the adapter remains securely seated in its PCIe slot. Loose connections can lead to intermittent network issues.
• Integrita kabelu: Use high-quality Ethernet cables (Cat5e or higher) and ensure they are not damaged or kinked.

7. Řešení problémů

If you encounter issues with your Cudy PE25 network adapter, refer to the following troubleshooting steps:

• Žádné síťové připojení:
  • Verify the Ethernet cable is securely connected to both the adapter and your network device (router/switch).
  • Check the Link/Speed/Act LEDs on the adapter. If they are off, there might be a cable issue or the adapter is not receiving power/signal.
  • Ensure the adapter is properly seated in the PCIe slot.
  • Check Device Manager (Windows) or network configuration (Linux) to confirm the adapter is recognized and enabled. Reinstall drivers if necessary.
• Slow Network Speeds:
  • Ensure your router/switch supports 2.5Gbps speeds.
  • Use a Cat5e or higher rated Ethernet cable. Older cables (e.g., Cat5) may limit speeds.
  • Update the network adapter drivers to the latest version from the Realtek webmísto.
  • Check network settings in your operating system to ensure the adapter is configured for full duplex and the correct speed (if not set to auto-negotiate).
  • Consider other network components (e.g., other network cards, router firmware) that might be bottlenecking performance.
• Občasné výpadky připojení:
  • Update drivers. Some chipsets (like the RTL8125) benefit significantly from the latest driver versions for stability.
  • Ensure the adapter is not overheating. Good airflow within the computer case is important.
  • Check for conflicts with other PCIe devices. Try moving the adapter to a different PCIe slot if available.
  • Disable power-saving features for the network adapter in Device Manager (Windows) if experiencing drops during idle periods.
