Using Windows 7, I found a problem: the use of download software (such as cyclones, express) when downloading, the time will automatically stop, download software will be in the drop state.
After groping, just understand the original network card power settings caused by the problem. If you have experienced similar problems, you can solve them by following these methods.
Go to Control Panel, click the Network and Internet Options, then click the Network and Sharing Center, click the Change Adapter Settings button on the left, right-click Local Area Connection, select Properties, click the Configure button button, switch to the Power management option, and deselect Allow the computer to turn off this device to conserve power ", and then click the" OK "button continuously. So after a long time to download, Windows 7 will not turn off the network card power, download will not frequently lose the line.
