What is the reason why home broadband keeps dropping?

The following describes how to solve the "frequent drops" of broadband faults:

If you are using a router, disconnect the router for stand-alone dial-up test;

If you have a modem device, you need to pay attention to whether the device is overheating, you can turn it off for a few minutes and then restart it.

If the connection drops when running the program alone (for example, when playing a game), it is recommended to restart the computer to try or reinstall the program;

If the entire network is disconnected, check whether the access cable and the network cable are loose or in poor contact, and try to reseat the line.

Check and filter out the disconnection caused by computer viruses and scan the whole disk.

If the program you are running has a server choice, select China Unicom.

First of all, it is necessary to judge the situation when the broadband connection is dropped, and according to different appearances, the real cause of the disconnection can be really found. The following is a targeted solution according to various disconnection phenomena:

1) A small red cross appears in the lower right corner of the computer when the connection is disconnected. Suggested solutions: It may be caused by poor network cable contact, network card hardware failure, or abnormal power supply of network equipment such as ADSL modem, and it is necessary to fix the network cable, equipment power supply or replace the network cable.

2) A small yellow exclamation mark appears in the lower right corner of the computer when the connection is disconnected, and it is suggested that the solution may be caused by poor network cable contact, network card hardware failure, or abnormal power supply of network equipment such as ADSL modem, check whether the ADSL modem status light is normal, and replace the network cable, restore the initial settings of ADSL, etc.

3) Disconnection when playing a game, but the webpage opens normally when the connection is droppedSuggested solutions: Some computer programs (such as firewalls and anti-virus software) may conflict with game programs, or the game service may be busy. It is recommended to change the game service area and exit other applications while playing the game.

4) Browse the web disconnection but QQ and other programs are normalSuggested solutions: Make sure that only one computer in your network is using the network, if there are multiple computers surfing the Internet at the same time, it will cause the opening of the web page to be abnormal. In addition, you need to check whether the computer browser is normal, it is recommended to change the browser or change the computer to try again.

5) When the connection is disconnected, no application can be usedSuggested solution: When you can't access the Internet, first use the ipconfig command to check whether the computer gets the network address, if the IP address is, it means that the dialing is not normal, you need to restart the dialing device, the computer and then dial again; If the IP address is normal, use the ping command to ping to check whether there is packet loss or whether the delay has timed out.

Broadband is always dropped is a problem we often encounter, and it is also one of the most difficult problems to solve, so how to completely solve the situation that the network is often dropped? Let's talk about it in detail.

The home network includes multiple hardware devices, and the drop may be caused by one or more of them, so the only way to determine which device is the problem is the only way to use the elimination method.

1. Check the modem and router.

Second, the optical signal is too low.

Summary: The network is often disconnected, mainly paying attention to the three aspects of optical modem, router and optical attenuation, and the disconnection does not occur in real time, so only long-term observation, using the elimination method, if there is a problem with the optical modem and the router, it can be directly replaced, if there is a problem with the optical signal, you need to contact the master to deal with it.

If you are using a router, disconnect the router for stand-alone dial-up test; If you have a modem device, you need to pay attention to whether the device is overheating, you can turn it off for a few minutes and then restart it. If the connection drops when running the program alone (for example, when playing a game), it is recommended to restart the computer to try or reinstall the program; If the entire network is disconnected, check whether the access cable and the network cable are loose or in poor contact, and try to reseat the line. Check and filter out the disconnection caused by computer viruses and scan the whole disk. Customer service number 221 will answer for you. WeChat payment, one-click check phone bill recharge, traffic, points, bills, and detailed orders can be self-service, convenient and fast.

You may have these reasons for this situation:

1.Your cat may be old and not have good heat dissipation!

2.Your broadband provider is maintaining the line!

3.The ** line in your area is aging, which affects the network transmission!

It is recommended that you call ** to customer service and tell him your situation in detail!

First check whether the connector of the network cable is loose, restart the cat, update the network card driver, scan for viruses or Trojans, or reinstall the system once, and if it doesn't work, call ** to the operator to ask.

This is because the bandwidth of the network is unstable, so it is recommended that users contact the operator's customer service to solve the problem and report directly to the network operator. It is recommended to test whether the power supply is on (if the broadband is confirmed, the user needs to confirm that the switch button of the CAT switch is connected to the power pon.) If the power is turned on normally, it is usually caused by a client-side fault (client-side LAN failure).

The LAN port status indicator does not light up. It is recommended to check whether the LAN cable connecting to the LAN port is falling off or loose, unplug the LAN cable again, and restart the device. The LAN port indicator flashes periodically like a second hand to check if the network cable is loose and causes poor contact.

It is recommended to call 10086 directly or install the main front with a call. Extended Information: Broadband Usage Notes:

The installation of fiber broadband is much more complicated than that of ordinary Qiming cables. When installing fiber broadband, both ends of the fiber must be cut off with professional tools. Make sure the ends are smooth so that the signal does not decrease.

Before proceeding with a broadband installation, a magnifying glass or microscope is usually used to check that the cut state of the fiber end is very smooth. Protective measures should be taken before the optical fiber connector is installed and connected. Since the mating part of the connector is prone to leakage of the received signal, it is easy to weaken the received signal if standard protection measures are not taken.
