What should I do if there is a flash break?

1.It may be a voltage problem that causes the broadband cat to restart and cause the connection to drop, find a multimeter to test the voltage to see if it is normal;

2.Check whether the status of the broadband cat is normal when the connection is dropped, there is a DSL or whether the link light is always on, the DSL or link light on the broadband cat indicates the communication status between your broadband cat and the operator's equipment room, it should be always on at normal times, if it is not bright or flashing, the biggest possibility is that there is a problem with your **line, directly call the operator's customer service** to report the obstacle and let people check and repair: Telecom 10000 Netcom 10060

But before that.

1) First of all, troubleshoot the disconnection caused by PPPoE protocol problems, if you are using Windows XP operating system, install system security patches, and then re-establish the dial-up connection; If it is not WindowsXP, reinstall the PPPoE number program, re-establish the dial-up connection, and then check whether the fault disappears. If the fault is solved, it is the operating system and the PPPoE protocol that cause the fault.

2) If the fault persists, then check whether the various wires of the ADSL modem and the separator are in good contact. If the contact is good, then check that the ADSL modem is not overheated. If it is overheated, turn off the ADSL modem and place it in a ventilated area to dissipate heat before use.

3) If the temperature of the ADSL modem is normal, then use the replacement method to replace the original ADSL modem and separator with a good ADSL modem and separator to see if the fault disappears. If the fault disappears, the ADSL modem or separator is faulty and can be replaced.

4) If the fault persists, in the "System Properties" dialog box that opens, click the "Hardware" tab, click the "Device Manager" button, and check whether the "Network Adapter" is selected. If so, remove it and then reinstall the network card driver. If not, upgrade the driver of the network card and see if the fault goes away.

5) If the fault goes away, it is a problem with the network card driver. If the fault persists, use the replacement method to check whether the NIC is normal. If not, replace the NIC.

6) If the fault persists, then check whether there are large transformers or high-voltage lines around. If there is, it may be caused by electromagnetic interference and frequent dropouts. Shielding the ** cable and the Internet connection cable.

7) If there is no large transformer or high voltage line around. Then keep the place where the ** line passes and the ADSL modem away from the cordless**, air conditioner, washing machine, refrigerator and other equipment, to prevent these devices from interfering with the ADSL modem (it is best not to share a power cord with the above equipment), and detect whether the fault is eliminated.

8) If the fault persists, you can check and kill the virus or reinstall the operating system, which will also cause frequent disconnections.

9) If the fault persists, it may be the ADSL line fault, and the telecommunications bureau can check whether the residence is more than 3000 meters away from the local computer room. Grab the top.

1. The line is unstable. In this case, the cable on the outside is generally aging, or the interface is not bandaged and rusty (may be due to rain), or the line is too long, and part of the signal is attenuated. 2. Intranet problems of users.

In this case, the outside line is connected to the inner line of your home, and the inner line of the home is buried in the wall, which cannot be seen by the naked eye, it may be that it has been too long or the problem of moisture, and the inner line of the home has begun to rust or rot, which will definitely affect the transmission of the signal. 3. The problem of moden (cat). It is possible that the cat used has a subtle malfunction because it has been energized for too long.

4. Computer problems. There is a virus in the computer, and this situation is actually relatively easy to tell. 5. If it is not dial-up Internet access, but a router, it is likely to be a problem with the router, and it is recommended to buy a *** router.

6. There is a problem with other computers connected to the router, which will affect other computers. Basically, it is the above several situations, if you can't deal with it, it is recommended to protect the warranty and let the staff maintain it.

Let the network service provider test the line quality of your home, they have a line tester to see if the line quality is normal, whether the attenuation is too large, etc. At the same time, it is recommended that the network service provider bring MD and notebook to test it at home, and ping the external network to see if it is the same situation, and use the elimination method to see. It should be possible to find the problem.

1. Network card problems. 2. MD problem. 3. Signal problems (external lines, equipment port problems).

The problem in the network is really nothing more than elimination:

1. You borrow a computer in your house and try to connect to the Internet. After a period of time, if you use someone else's computer without disconnecting, it is your own computer problem. As for the local bend, the chain should be destroyed and the network card driver should be reinstalled, or the system should be reinstalled, or the 360 security guard should be used, and the driver wizard should be dealt with.

2. If you use someone else's computer and it is still a flash disconnection, it means that it is a broadband problem. You can strongly ask the Weixian Lasun repair staff to come over, and tell him that it is not your computer's problem, and ask him to fix it for you.

There is an IP conflict on the intranet, or the network is unstable.
