Thank you so much! My drivers were last updated in 2015!!! Now I've got all the options is very nice connection speed.

Hello bvsp Pimenta,

Welcome to Microsoft Community.

I understand your concerns. Based on your description, it seems you are encountering limitations in the available properties and settings of the Realtek PCIe GbE series controller, which is usually related to the network card driver or hardware.

Here are some possible reasons for this issue:

1. Driver Limitations: The number of properties and their configurability are usually determined by the installed network card driver. If your driver is outdated or not fully compatible, you may not see all the options mentioned in other tutorials. Ensure you have the latest Realtek driver installed from the official website or through Windows Update.
2. Adapter Capabilities: Not all network cards support the same set of advanced features. Some older or lower-end adapters (such as certain Realtek models) may have limited settings compared to more advanced cards. If your controller does not support certain features (like higher buffer sizes), you may not see them in the properties menu.
3. Hardware Limitations: Some settings (like buffer sizes) may be limited by the hardware itself. The values you see for Receive Buffers and Transmit Buffers are the maximum that the hardware can handle. If you cannot increase them beyond certain limits (like 512 and 128), it may be the maximum supported by the Realtek adapter.

Troubleshooting Steps:

1. Incomplete or Outdated Drivers: Network card drivers facilitate communication between the operating system and the network card hardware. If the driver is incomplete, outdated, or has compatibility issues, it may prevent certain advanced features from being displayed or configured. Manufacturers typically provide drivers specific to the operating system and hardware, which may include additional configuration options. When watching videos, ensure the creator's configuration and driver version match yours; otherwise, it's normal not to see the same content. Solutions:
   • Update Drivers: This is the most common solution. Visit your computer or motherboard manufacturer's website (if you built your own PC) to find the latest network card drivers for your model. Alternatively, you can visit the Realtek website to download the latest Realtek PCIe GbE series controller drivers. After downloading, uninstall the current driver (find the network adapter in Device Manager, right-click and select "Uninstall device"), then install the newly downloaded driver.
   • Rollback Drivers: If updating the driver does not resolve the issue or makes it worse, you can try rolling back to a previous driver version. In Device Manager, find your network card, right-click and select "Properties," then go to the "Driver" tab and click "Roll Back Driver."
2. Network Card Hardware Limitations: While Realtek PCIe GbE series controllers typically support many advanced features, certain specific models or older hardware versions may have limitations at the hardware level, resulting in fewer configurable parameters. Solution: This is less common, but if updating the driver does not resolve the issue, it may be a hardware limitation. You can try to find the specific specifications of your network card model to confirm its supported features. Alternatively, you can consider replacing the network card with one that supports more advanced features.
3. Buffer Size Limitations:
   • Explanation: The size of the receive and transmit buffers is usually determined by both the driver and the hardware. The driver may set a limit on buffer sizes to ensure system stability and performance. The high values shown in tutorials may be for different network cards or driver versions.
   • Solution: You are unlikely to directly exceed the buffer size limits set by the driver. Instead of pursuing excessively high buffer values, focus on other important network optimization settings, such as ensuring a stable network connection and reducing network congestion.

Regarding Game Optimization:

While adjusting advanced network card properties can impact network performance, the following factors are more important for gaming:

• Stable Network Connection: Ensure your network connection is stable to avoid packet loss and latency.
• Sufficient Bandwidth: Ensure your internet connection has enough bandwidth to support the game's requirements.
• Low Latency: Minimize network latency, for example, by using a wired connection instead of a wireless one.
• Game Server Selection: Choose game servers that are closer to you and have lower loads.

You should first try updating the network card driver, as this is the most likely solution. If the issue persists, you can check for hardware limitations or consider other network optimization methods. Don't focus too much on buffer size limitations; it's more important to ensure overall network connection quality.
