Hardware problems:
1. Do not know the computer model (the computer has been restructured)
2. reinstalled the new system and transitioned from XP to win7.
3. The computer was updated a long time ago. Of course, I don't know if the NIC has been updated, and the driver has not copied the archive.
Problems:
1. Download the universal NIC Driver and find many universal drivers that only support the XP system. There are not many universal drivers for win7.
2. After the driver for win7 is found, "this device cannot be started (Code 10)" appears after installation )".
3. After the driver is reinstalled, the problem is solved, but there is still no network connection. It is assumed that the motherboard and the NIC driver are not compatible, and the result is verified.
Solution:
Finally, I downloaded Master Lu (no Internet connection) and got the computer configuration, including the nic and motherboard. The corresponding nic and motherboard model downloaded the corresponding driver. After I got the Internet access, use the driver genie to download all drivers.
Summary:
When you know the computer model, installing the system is the most convenient. If the system configuration changes, you 'd better download a software and check your computer configuration, this will make the system more stable!
