Some controls on this property page are disabled because one or more other network page properties have been opened. To use these controls, first close all property pages and then re-open this property page.

Recently, when you open a network connection, a dialog box is often displayed when you view the Local Connection Properties: "Some controls on this property page are disabled because one or more network page properties have been opened. To use these controls, first close all property pages and then re-open this property page"

In:

 

1. Turn off the wireless network card
2. Check the network cable (my network cable is not very good, I found it after checking) to ensure that the connection is normal
3. Stop the IP Helper Service: [STEP: start -- run -- msconfig -- service -- IP helper (cancel the check mark above )]
4. Configure IP
