There are many factors that cause network disconnection. You can follow the steps below to find the reason for the failure.
1, completely antivirus the computer, and the virus can lead to network disconnection.
2. Your broadband is connected to the telephone. Check whether there is any quality problem with the telephone filter, and unplug the telephone to see if the problem is solved.
3, ADSL cat quality problems, conditional try to replace ADSL cat.
4. Line problem is one of the main reasons for line disconnection. The line is aging, damp, poor contact, loose connector, and there is something wrong with the port of the computer room. , all of which will cause the line to be disconnected.
5, network card or network card driver problems may lead to dropped calls.
None of the above methods can solve the problem. Call the broadband operator's customer service phone directly for repair, and let them handle it for you.
Question 2: Telecom broadband at home is always disconnected. What is the reason? Hello! Thank you for your support to Telecom! It can be handled as follows: 1. The possible reasons for broadband disconnection are: unstable power supply voltage, static electricity of computer network card/chassis, computer poisoning, system software failure, etc. It is suggested that you give priority to self-inspection or ask computer maintenance personnel to help troubleshoot. 2. You can check whether the modem and splitter hardware are faulty, whether the splitter is connected correctly, and whether the modem is compatible with the network card. It is recommended that you change other modems to observe the usage. 3. If you disconnect while playing a game, it may be related to the application server. I suggest you contact the game provider for verification. 4. If the above operation fails, you can choose the following ways to report the failure: (1) dial 10000, and select key 4 to report the failure of broadband; (2) Feedback to China Telecom QQ Customer Service 800010000 through computer or mobile phone; (3) Log in to the online business hall of Hubei Telecom (hb. 189), fill in your broadband account number, fault phenomena and effective contact information on the "Complaints and Troubleshooting" page under the "Help and Support" column, and report the fault. I hope my answer is helpful to you. More questions can be found in Hubei 10000!
Question 3: Why is Unicom's broadband always disconnected? Because Unicom's network cable layout is not very good, it is often disconnected.
I suggest you change the network of other suppliers.
Question 4: What if the broadband connection is always disconnected automatically? Computer pages are as beautiful and charming as the sea, which makes people feel relaxed and happy ... Under the calm sea, some marine animals kill each other and some warm each other; There are many algae and so on, this is the world! It seems calm, but it is not. Computer pages are like the sea, ........................................................................................................................................................................ If not, don't be angry! Sit down, have a cup of tea and cheer up. In hot summer, the temperature is very high. Don't you feel hot? Equipment (equipment refers to: cats, routers, network switches, Hubble, computers, etc. ) will also feel hot and will not work; You may wish to refer to the following methods and take measures that you think are acceptable to reduce the working environment temperature of the equipment. Answer: Users who have been surfing the Internet for at most half a year should open the equipment shell and clean up the dust inside the equipment after power failure. B: Put the equipment in a safe place for people, open the box cover of the equipment, and use air convection to strengthen the contact surface with the air for natural heat dissipation; C, installing a micro fan on the equipment to increase air convection and carry out forced heat dissipation; D: If you are an IT worker, I suggest that you add a heat sink to the heating part of the equipment after disconnecting the power supply. E: After the equipment is disconnected from the power supply, drill a lot of holes on the equipment with a 3mm drill bit to strengthen air convection and improve heat dissipation conditions; F: As for the equipment in the ventilated and dry place, it is best to make an insulating bracket to support the equipment to dissipate heat naturally; G: Clean up the garbage fragments and IE cache generated by surfing the Internet in time, and arrange and run the C disk regularly, which can appropriately improve the running speed. H: synchronize ADSL cat first: turn off the cat's power and restart it. One: Software settings are reasonable, and three things are not installed: no informal software, no P2P software, and no uncommon software. Turn off all unnecessary network connections, such as thunder BT donkey; J: I personally recommend using gadgets like Super Rabbit to optimize the network. K: A computer should have at least one valid genuine antivirus software installed. L: Network card problem: The bandwidth of the network card is appropriate and it works stably. As long as you do the above aspects well, your fault will be eliminated; Thank you for taking my answer! Thank you: friends!
Question 5: How is it that the computer always disconnects and automatically connects? 1. Eliminate the contact between the network cable or the crystal head and the connection.
2. It is possible that the broadband cat is disconnected because of the voltage problem. Find a multimeter to test the voltage to see if it is normal;
3. Eliminate the above two reasons, which may be caused by the mismatch between the speed configuration of your computer network card and the Ethernet port of the connected device. You can try to modify it as follows: right-click network neighbor-properties-right-click local connection-properties-general-configuration-advanced-connection speed and duplex mode, and the original "adaptive" can be changed to "10M full duplex".
Q:
The voltage can't be suddenly abnormal. It has been used at home for several years. Is there anything wrong with cats?
Answer:
The possibility of general hardware failure is not too great. You can try according to the third rule first.
Question 6: What is the reason for the frequent disconnection of broadband connection? How to deal with it? First, check whether the network cable is loose. For most broadband users, ADSL cat-to-wireless router is the most common networking mode. When you are disconnected, the first thing to consider is the line problem. Because the telephone line is too long, there are too many connectors, or there are some interference sources, it may cause disconnection, and the inferior and substandard network cable often causes network instability, so when the disconnection is found, first check whether the network cable interface is loose. If it is found that the network cable interface is intact, it is necessary to check the problem of the power signal lamp. Second, whether the power signal lamp is always on If the power signal lamp is not on, first check the power problem. For example, whether the line is disconnected because of the unstable power supply of the mains, whether there is a problem with the power supply of the ADSLModem itself, and so on. Touching the ADSLModem shell with your hand feels very hot. At this time, you might as well turn off the ADSLModem temporarily, wait until it cools down, or put it in a ventilated place, or you can eliminate the disconnection fault. Third, check whether the data signal is normal. If the data signal light is not on, it is likely that the line is open or short. Then pass the telephone test to see if the line is normal. If it is not normal, we can help the technicians of ADSL service providers to solve this problem. If the data signal light flashes, it is probably caused by poor line contact. You must check whether the extension is used, whether the connector is firm, and whether the ADSL cable is too long. If the data signal lamp still doesn't light up after checking according to the above steps, it means that the fault has nothing to do with the line, and continue to look for other reasons. Fourth, whether the network card signal lamp is stable Under normal circumstances, after the network card in the computer is connected to the ADSLModem through the network cable, its signal lamp should remain flashing or always on. If the signal light of the network card is in an unstable state, that is, it is not bright or flashing, it is likely that the connection between the network card and the network cable has failed. In addition, you need to check whether the network card is loose, whether the network card driver is installed correctly, whether the network card resources conflict, and whether the network cable connector is loose. If it still can't return to normal, it means that the fault is not caused by the network card or network cable. 5. Network addresses cannot conflict. If the IP address of ADSLModem conflicts, or the address of DNS server is set incorrectly, ADSL will also be disconnected. If you are a virtual dial-up user, you don't need to set your own IP address, just choose automatic allocation. If a fixed IP address is used, be sure to check whether the IP address conflicts with the IP addresses of other workstations in the same network segment, and also check whether the DNS address setting is correct and whether the TCP/IP parameters have changed. After these troubleshooting, if you still can't troubleshoot, you have to find the reason from the dialing software. 6. Check whether the dialing software works normally. First, double-click the dial-up program on the desktop of the system with the mouse to perform broadband dial-up connection operation. If you find that the system has an error prompt of "Unable to connect" during dialing, you can click the "Retry" button in the prompt window. In general, redialing 3 to 5 times can solve the problem. If you can't connect successfully after redialing for 3 to 5 times, we can consider turning off the broadband "cat" power supply for a period of time before turning it on, and using the Ping command to test the IP address of the broadband "cat". If you can Ping the IP address of the broadband "cat", we can redial. I believe this will probably solve the problem. If you still can't dial, you might as well restart the computer system and dial again and again. If such efforts fail to solve the problem, it is likely that the modem in the telecom room has locked the user account. At this time, you can only contact the telecom staff to help unlock it. If you can surf the Internet normally without modifying the TCP/IP parameters, you might as well delete the TCP/IP protocol now, and then reinstall and set it correctly, which may solve your disconnection fault. Seven, the load is too large, which is also one of the reasons for broadband disconnection. For example, we often use BT. For example, someone in the broadband network is downloading BT, which is likely to cause the router to disconnect. This often happens in student dormitories or small office networks. In order to avoid this situation, we can limit the traffic and bandwidth of BT download, so as not to affect other users' normal online access, especially those like CM, FTT, etc. & gt

Question 8: What should I do if my home network is always disconnected? Step 1: Download a 360 security guard.
Step 2: check all aspects of the computer-> functional encyclopedia-> network optimization (left menu)-> installation: router guard, LSP repair, DNS optimization. When these three things are done, the network will be much more stable.
PS: The router guard is to see if anyone is surfing the Internet (if you are in a good mood, don't pretend. ), LSP repair makes the network stable and DNS optimizes the speed-up network.
Finally: Sometimes congestion is the reason why the router works for a long time, and it can be solved by restarting the route and the cat.
Question 9: My broadband is often disconnected. What's going on here? Did you use the route?
There are several reasons for this problem:
1, the line quality is not high, and the middle joint of the line from the telecommunication bureau to your home is oxidized; This should be checked by the telecom company.
2. Check whether your ADSL cat is of poor quality. If the temperature is high, there will be problems. You can borrow a cat from your classmates and friends if you have the conditions!
3. Check whether the connectors of the network card, network cable and telephone line are in poor contact;
4. If you use a router, there may be two problems: one is the limitation of the number of machines carried by some routers, the other is the quality problem, which is overheated like a cat; In addition, the operator prohibits routers from enjoying it and checks it every once in a while. If it is found, it will be disconnected.
Try one by one first.
Question 10: Why is the mobile broadband always disconnected? Normal, because it's cheap, but you have to believe that China Mobile has a better attitude and a faster solution than other telecom operators.
