Prevent Windows From Turning Off the Ethernet Driver

Windows may turn off the Ethernet driver to save power, which can lead to frequent disconnections. To prevent this, adjust the power management settings for the Ethernet driver. In the Device Manager, open the properties of the Ethernet driver, switch to the Power Management tab, and uncheck the option to allow the computer to turn off the device to save power. By disabling this setting, you ensure that the Ethernet driver remains active and prevents disconnections.

By default, Windows is programmed to prioritize power saving over network stability. This feature is intended to conserve energy, especially for laptops and portable devices, but it can impact the reliability of your Ethernet connection. Disabling the power saving option for the Ethernet driver ensures that it remains constantly powered, eliminating any potential interruptions due to power management.

When you disable the power-saving feature, your Ethernet driver will always be active, even during periods of inactivity. While this may slightly increase power consumption, it guarantees a stable and uninterrupted connection, especially if you rely heavily on Ethernet for gaming, large file downloads, or video streaming.

Keep in mind that disabling the power-saving feature for the Ethernet driver may not be necessary for all users. If you primarily use Wi-Fi or don’t experience any frequent disconnections, there may be no need to make this adjustment. However, if you have been troubleshooting Ethernet connectivity issues and have exhausted other solutions, adjusting the power management settings can be a worthwhile step to ensure a consistently reliable connection.

Summary

To prevent Windows from turning off the Ethernet driver and causing frequent disconnections:

  1. Open the Device Manager.
