Second, start → run, input msconfig→ OK. In an open system system configuration program, turn off some of the unimportant services and startup programs, and restart the computer.
Third, go to "My Computer"--Tools--Folder Options--View--Cancel the "Automatically search network folders and printers" check.
Four, start → set → network connection → Right-click local area → properties → Double click Internet Protocol (TCP/IP) → Specify the IP address and subnet mask using the IP address below if the IP address is empty. If you can set the IP address to 192.168.0.X (any value between X 1-255), the subnet mask can be set to 255.255.255.0→ OK → OK.
