If your laptop is connected to the network but still cannot access the Internet, the possible reasons are:
1. Connected to a local area network, only for internal use;
2. If you are connected to a wireless network, the wireless router may not work properly and cannot connect to the external network.
3. Connect to the Intranet, but the external network is blocked, maybe the server card, or the network cable is not in good contact;
4. The external network is paralyzed, because the light is dug out and other reasons, resulting in a large area of network interruption, and naturally, it is not possible to access the Internet.
5. The connection to the network is only partially connected. If the above problem occurs, the Windows system will prompt you that you cannot connect to the Internet.
