About the strange failure of the computer to connect to the network, you know, thank you

It's actually very simple, it's not a problem at all, just wait a little longer when you turn on the next time you turn it on.

Under the settings in PPPoE, do not turn on the connection, use manual connection.

Reboot the computer or a cat?

Wait for the router to be stable before connecting to the network!

If it is confirmed that the network cable is damaged, you need to consider the crystal head, and try to replace the crystal head if the contact is poor. If you want to know if it is a route problem, you can observe the router at home, generally the fast flashing is no problem with the line, if it does not light up and slow flashing is the line problem.

Check whether other devices can access the Internet normally, and then restart the router and computer, if you can't solve the problem by yourself, it is recommended to contact the after-sales customer service of the computer brand.

This one is very simple, ask a computer repair engineer to check it.

Just reconnect.

1.Check the system first, fix IE or install Maxthon and other browsers, redo the system, if it can't solve the problem, rule out this aspect.

2.Uninstall and reinstall the network card driver, change the slot of the network card, whether the network card light is always on, check whether the backsplash of the chassis is live, if you find the wire grounding by yourself, try to eliminate this factor.

What is the display of the dialer indicator light, whether the computer light is always on or flashing or the external line light is always on or flashing. Replace the ADSL dialer if all are normal to rule out this aspect.

4.Whether someone else's computer can access the Internet normally in your place, the premise is not the ADSL installer's laptop; Whether your computer is available from the Internet. If you are in another out, you can turn 5.

5.Ask Netcom to replace the ** line, pay attention to start from the bus instead of just replacing the one at home.

There will be a red cross on the network connection, which is usually caused by these situations:

1: The network cable is broken or the crystal head is damaged, check whether the problem is solved, and replace the network cable to solve it.

2: The network card is not enabled or the network card is faulty, find my computer on the desktop of the computer, right-click management - device manager - network adapter - open to find your network card first try to right-click to enable, if it is enabled, right-click the properties, open the driver page to check whether the driver is working normally, if it is not normal, you can update or restore (after restarting).

3: Find the Network and Sharing Center in the taskbar in the lower right corner of the desktop, click on the local connection, and see if the network is enabled.

Because we know that if the network is limited or the operator is in trouble, the network icon will show an exclamation point instead of a red cross, which is usually due to hardware problems.

1. Maybe your network cable is loose and the crystal head is in poor contact, just plug and unplug the crystal head again. Second, maybe your network card is broken, just replace the network card. 3. There may be an error with your network driver, reinstall the network driver.
