The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test. If it is a problem with the broadband, contact the broadband customer service to solve it.

2) If it is a problem with the router, if it used to work but cannot be used temporarily, my own practice is to cut off the power of the router, plug it in, and wait and see. If you have it, you can restore the factory settings and strictly follow the instructions to set it up again. If you don’t understand it, it is not recommended to set it up by yourself (this is under the premise that the physical connection is correct, sometimes it is caused by the router being slow or failing to find the IP address, and It’s not that the router is broken).

3) If you turn off the wireless switch, just turn it on. If you use software to connect wirelessly, it is normal that the software is not easy to use and often causes problems. If there is no better way, use a router. In addition, it is caused by the lack of or inappropriate network card driver, whether there is a problem with the network cable interface or the network cable, etc.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.
