I would recommend uninstalling the driver from the device manager.
Click on the Start button> Type Device Manager in the Search bar and select it>Go to Network adapters and uninstall the Intel driver. (Make sure you download the driver from the link below before you uninstall it.)
Intel I219 NIC Drivers for DTO Microsoft Win 7 -64bit
Once you install the driver test it and if the issue is still present go back to the Device Manager> Network adapters> Right click the Intel Ethernet driver and go to Properties>Power Management tab> And make sure the check box for "Allow the computer to turn off this device to save power" is unchecked.
