1. It is generally a problem for network operators that computers can't get online. After a while, they will be able to surf the Internet automatically. You can check the indicator status of broadband cats. If the indicator light keeps flashing or doesn't light at all, it's not the computer's problem, but the network signal doesn't come to the computer. You can call the network operator (Telecom or China Unicom) to solve the problem.
Usually solve it at home within 24 hours. If the signal light of the broadband cat is on all the time, it proves that the network is normal. Please find out the cause of the problem of the computer or router, switch and network card.
2. Sometimes, whether computers are connected to the Internet is a question of system settings. If it is ADSL broadband, please re-establish broadband connection and re-dial the Internet. If a router is connected, you need to check whether the router settings are correct. For general router problems, you can restart the router or reset it.
If there is a network virus in the computer, the computer may not be able to access the Internet. Antivirus software or reinstalling the system can solve this problem.
