Windows7 system prevents the NIC from being disabled. The

user's Windows 7 system has an overnight download. The next day, I found out that I don't know why I can't get on the network. Later I figured out that the NIC is disabled. The following is to prevent the NIC from being disabled. Setting method.
1. Right click on the computer icon and select Properties from the pop-up context menu.
2, on the "Control Panel Homepage", click with the left mouse button "Device Manager".
3, in the pop-up device manager dialog box, find "network adapter", right click on the driver, click "ldquo; attribute" in the menu that comes out, if the network adapter can not be found in the device manager , restart and try. Alternatively, you can open the properties dialog by double-clicking on the driver in the network adapter.
4, in the open properties dialog box, find "Power Management", remove the "Allow the computer to turn off this device to save power", and then click OK.
The network card is automatically disabled because Windows 7 has the function of automatically saving power. After the above settings, the network card will not be automatically disabled.
