The computer network is not good What's the message number of Cat Lao?

1) If it is a broadband problem, directly connect the broadband network cable for testing. If it is a broadband problem, contact broadband customer service to solve it.

2) If it's a router problem, if it worked before, it won't work for the time being. My own way is to disconnect the power of the router and plug it in. See you later. If it can be restored to the factory settings, it can be used in strict accordance with the instructions. You don't understand, so it is not recommended to set it at will (this is sometimes caused by the slow or failed IP address search of the router under the premise of correct physical connection, not the router is broken).

If I can't solve it all the time, I suggest calling the customer service of the router. They have telephone online guidance. If I encounter problems that I can't solve, it is very useful to ask their advice. They will provide correct advice for your setup or operation.

3) If the wireless switch is off, just turn it on. If it is a software wireless connection, the software is not easy to use, and it is normal to have problems frequently. There is no better way to use a router. In addition, the network card driver is not suitable or not suitable, and there is something wrong with the network cable interface or network cable.

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