What s going on with my home s computer network?

The estimate is that if your cat problem is reopened, if it doesn't work, call someone else to check.

That's yours, the modem is broken, ="Cats"It's bad, when I used to use Tietong, I often did this, and my dad called ** to me for a piece of line, and I called** to Tietong**, always error 678, restart the computer or cat. Sometimes they're repairing. Alas...

But I'm OK with Huashu broadband now.,Directly connect to the computer with a cable。 No need for cat linking.

If your computer system is all driven, you should be able to conclude that it is not a computer problem.

If there is no local link, it is a problem with the network card in the computer.

Possible scenarios:

1.For router settings, it is recommended to set both the router and the computer to automatically obtain the IP

2.Check whether the router is set to MAC address binding If it is set, if your computer's MAC address is not in the router MAC address list, it is not possible to access the Internet through the router, it is recommended to turn off this function or add your computer's MAC address to the router MAC address list

3.Check whether DHCP is enabled on the router

4.When the computer is connected to the Internet, log in to the router page to see if the computer host address is in the router host list, or after the network is disconnected, you can see whether the computer is connected to the network

5.Click on the system network repair, let the system repair the computer network by itself, and the system also has feedback results, you can refer to it

6.It is recommended to update the network card driver of the computer, and you can use the driver wizard to update other drivers of the computer by the way

7.Check whether the router broadband dial-up (if you use the router dial-up to access the Internet) is correct You can fill it in again, this must be correct

8.It is recommended that you can also use a sharp object to press the reset button on the back of the router to restore the router to its factory state, and then set the router again

9.It is also possible that there are some problems with the network cable, for example, the crystal head may be damaged, resulting in poor contact under the pretext, 10, and it is also possible that the network operator's network is not very stable, (this should be contacted by the operator).

The problem is not clear, can you describe it clearly?

651 is your computer's operator signal is good and does not give you you, your adapter can't find the signal, you look at it when it's not your network cable dropped, or the cat is broken. This error is directly reported to the operator: China Telecom, China Mobile, etc., depending on which one you are looking for.

Broadband is not connected, and sometimes it can be connected, which is called frequent drops.

There are several reasons for frequent broadband (network) disconnections.

1. The line is caused by the problem, check the joint part of the line, it is estimated that the joint is loose, and after finding the fault point, the joint can be reconnected.

2. If the voltage is low, you can buy a voltage regulator to temporarily solve the problem of low voltage, and then find the power department to solve the voltage problem.

3. If the network card is faulty and the network card is loose, tighten the network card or replace the network card Take a look.

4. If the cat or router is disconnected due to overheating during use, you can turn off the cat and router first, and then continue to use it after heat dissipation, or it can be solved.

This situation is usually caused by the network, and you can contact your network provider directly and ask them to check and improve the network environment.
