Windows 7 is frequently dropped. It is not the fault of downloading

Recently, many users who use Windows 7 system sent emails to 45IT.com, which is about the frequent dropped calls under Windows 7 system. According to the user's description, in Windows XP system (in the case of the system default settings), downloading movies with Thunder or Express is normal, but when switching to Windows 7, the Thunder or Express will stop downloading. These users think that Thunder, Express and Windows 7 are not compatible, or think that Thunder and Express have grabbed bandwidth, so they frequently drop the line.

After a few days of testing, the author found that the situation reflected by Windows 7 users does exist, but did not reach the "frequent" situation. At the same time, it is not that Thunder or Express has grabbed the bandwidth. (Even if I grab the bandwidth, the form of the performance is slow, not dropped.) In the process of the author looking for the problem, I think it is caused by the Windows 7 system's default settings for the power management of the network card.

In the Control Panel, right-click Local Area Connection and select Properties from the pop-up menu (Figure 1). At this point, the “Local Area Connection Properties” dialog box will appear, click on the “Configuration” button (Figure 2).

Then the system opens the NIC Properties window. In this new window, switch to the "Power Management" option and uncheck "Allow the computer to turn off this device to save power" by default in Windows 7 (see Figure 3).

After the modification is completed, save the settings and exit.

This article is only a solution for the dropped line, not to say that the drop of the Windows 7 system is caused by the power management of the network card.

At the end, I will leave a small question for you. Why do you say (in this article) cancel the "Allow computer to turn off this device to save power" option by default? What about the line?
