③Some notebooks have a physical switch or shortcut key Fn F2 to turn on and off the wireless network. Just turn it off and then restart it.

Why does the WiFi received by the laptop have an exclamation mark

There are many reasons for this situation.

There is no problem with the signal connecting to the wifi, but there is a problem with the network where the external network cable is connected to the router. Even if the external network is disconnected or invalid, it will cause this problem.

1. It is generally recommended to right-click on the exclamation point, open the Network Connection Center, and then search for the problem. If the network map shows that the LAN is connected, but the LAN is disconnected from the Internet, it is an external network problem.

2. Use computer clinics such as QQ/360/Rising Security Guard to repair the problem of not being able to access the Internet.

3. The setting problem of unlimited routing. The network connection username and password of the wireless router must be set correctly. If you were able to connect before and now you can't, you can ignore this reason.

4. System problem. If you have tried many methods but failed, it may be caused by system file loss, damage, compatibility and other issues. At this time, you can consider reinstalling the system.
