What does an exclamation point mean when connecting to a laptop wireless network?
Wireless network settings and troubleshooting steps:
①The wireless network card driver is not updated or does not match.
Solution: Enter the Control Panel from the Start menu, find System Options, then select Hardware and click Device Manager. Locate the network adapter in Device Manager, right-click the wireless card and select Update Driver Software. Follow the prompts step by step to complete the update.
②The wireless network service is not activated.
Solution: Start→Control Panel→Administrative Tools→Services→Wireless Zero Configuration→Enable
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.
④Wireless router signal difference:
Solution: Signal attenuation is due to the limited launch distance and the influence of wall corners. Users often ignore this difference. You can shorten the distance first and gradually widen the distance.
⑤Faults such as local connection restrictions.
Solution: Start→Control Panel→Network Connection→Wireless Network→Properties→Check the tcp/ip protocol inside - whether the IP address and DNS address are automatically obtained, if not, change to automatic acquisition.
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.
