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 broadband customer service to solve it.

2) If it is a problem with the router, if it used to work, it 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, just restore the factory settings and re-set it and it will work (this is on the premise that the physical connection is correct, sometimes it is caused by the router being slow or failing to find an IP address, and it does not mean that the router is broken).

If you still can't solve it, it is recommended to call the customer service of the router. They have online guidance by phone. I encountered a problem that I couldn't solve. It is very useful to consult their suggestions. They will help you with your settings or operations. Gives correct advice.

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.
