How can I handle the browser secondary webpage under Win7?

The second-level webpage is actually the next-level directory of the homepage. Maybe you are surfing the Internet in peacetime, suddenly discovering that the website is opening more and more slowly, and then you can only open the navigation of a website. The secondary page under navigation is a connection failure. What is going on?

Operation steps:

1. This problem occurs because the DNS address in the computer network settings has been tampered with. It is unclear how this setting has been tampered with. Follow the steps below to solve this problem.

2. Open the network and sharing center.

3. Change the adapter settings.

4. Find the currently used adapter, right click on the mouse and select “properties” from the drop down list.

5, then left-click on the protocol version 4.

The server points to a website that is unknown to the user.
