This utility resolves an issue where during system resume, the Intel 82579V Gigabit Ethernet PHY Network Connection erroneously reports the device id as an Intel 82579LM Gigabit Ethernet Controller Network Connection, resulting in a Windows* Code 10 error and loss of network connection.

Not all systems with the Intel 82579V Network connection will see this problem. Systems using Microsoft Windows 8 and above are more susceptible to the issue.
If you experience this error, Intel recommends that you update the non-volatile memory for your network connection by downloading and running the NVM Update Utility.

It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
