What if the computer is disconnected?

If your computer can't connect to the network after disconnecting, it may be caused by the following reasons:

1. Router failure: Check whether the power supply of the router is normal and whether there are other connection problems.

2. Network interface problem: Check whether the network cable, wireless network card and network driver are normal.

3. Firewall problem: Check whether the firewall settings are wrong and whether the network connection is blocked.

4.DNS problem: Try to change the address of the DNS server and check whether you can connect to other websites.

Here are some solutions:

1. Restart the router: Try to restart the router first, which may solve some router failures.

2. Check the network interface: check whether the network cable, wireless network card and network driver are normal. If they are not normal, you can reinsert or reinstall the drivers.

3. Turn off the firewall: If the firewall settings are incorrect or prevent network connection, you can try to turn off the firewall or reset the firewall.

4. Change DNS server address: Try to change DNS server address. You can solve the problem by changing the DNS server address of the computer or the DNS server address of the router.

In short, if there is a problem that the computer is disconnected from the network and cannot connect to the network, the router, network interface, firewall, DNS and other problems can be eliminated first, and then corresponding solutions can be taken according to the specific situation.
