1. Please clarify the problem. Where the wire is dropped may be caused by the loosening of the terminal post and the vibration. The wire can be fixed by soldering.
2. Try another network card
3. You don't believe how to improve the network speed by using any software or measures. You can only remove some garbage from your computer on your terminal and optimize the running environment of your equipment, so as to improve the processing speed of your terminal (computer); Just like the water pressure of a waterworks is low, you are increasing the diameter of your water pipe, which can not solve the problem of your water pressure; You can't speed up the Internet! Isn't this just talk about deceiving people? Deception only talk, whimsical, unless you find the monkey king to improve network speed! Network is a concept of network, which is qualitatively different from a terminal
for the network, no matter what form of computer network or transmission medium, what kind of terminal equipment, or how advanced network switch;

4. It's the LAN bar. It's people playing with software like the guardian God of P2P network. That's what happened in your apartment. You hurt me and I hurt you. Now everyone is suffering
5. This situation is generally caused by operators' lines, cats, routers, etc
1. Check whether the crystal head of the lower network cable and telephone line is aged or rusty. If it doesn't work, it will be redone. If it doesn't work, it won't affect it
2. The cat is very hot when it is open for a long time. It is suggested that the cat should be placed in a ventilated place instead of overlapping with the router. So as not to overheat. It's really not good. It's recommended to change to a cat with good performance
3. Several computers share the same network. Because the router is too bad, others will drag the router to death when they watch movies with P2P. The router will be better when it is restarted. The long-term solution is to replace it with a better enterprise router
4. The business opportunity room is far away from your home, beyond the distance of ADSL, line fault, etc., so they are required to measure the signal strength and line condition (sometimes two lines, broken one can also access the Internet, but the network speed is slow, easy to drop, ordinary people can't find it).

6. I also have this problem today, but I have a new connection problem solved at once. If you need to add my QQ, I will teach you the specific operation....
7. 1. According to the information you provided, if you mean that Unicom broadband is frequently offline, which affects your access to the Internet, it is recommended to remove the obstacles through the following ways:
[1] if you are using a router, first disconnect the router from the stand-alone dial-up test
[2] if there is a modem device, you need to pay attention to whether the device is overheated. You can turn it off for a few minutes and try to restart it again
[3] if the program is disconnected when running alone (more than when playing games), it is recommended to restart the computer to try or re install the program
[4] if the whole network is disconnected, please check whether the access line and the network line are loose or in poor contact, and try to plug the line again
[5] check and filter the broken line caused by computer virus, and scan the whole disk
[6] if the running program has a server option, please select China Unicom
2. If the problem can not be solved after the above troubleshooting, we suggest that you contact the local Unicom manual customer service to report the problem, and our company will check and handle it for you as soon as possible
you can also focus on China Unicom WeChat official account, click "customer service > broadband failure reporting > common fault guide" to see how to handle the corresponding faults. If br / > is still not resolved, you can help yourself with the following obstacles:
[mode 1] pay attention to China Unicom WeChat official account, click "customer service > broadband barrier block online".
[method 2] log in to the app of mobile phone business hall of China Unicom and click "Service > broadband > Broadband Service > broadband report".

8. Look at the router interface
the router is aging
turn off the router for one night, and try to
arp broadcast virus the next day
kill all viruses

Frequent disconnection and re insertion of network cable can solve this problem, which is mostly caused by poor contact of crystal head of network cable. Re crimp the new crystal head
there are two methods of network cable, one is cross line, the other is parallel (through) line
the method of cross line is: one end adopts 568a standard, the other end adopts 568B Standard
the method of parallel (through) line is: both ends are 568a standard or 568B standard (generally, 568B parallel (through) line is used)
568a standard: white, green, green, White orange, blue, white blue, orange, white brown, brown
568B standard: white orange, orange, white green, blue, white blue, green, white brown, brown
the difference between the two methods is the exchange of white orange (white green) and green (Orange)
10. There are many reasons for network disconnection, which need to be analyzed concretely:
1. The network cable of network equipment is damaged, but it is rare to replace the equipment and cable
2. Check whether there are a large number of people downloading or using P2P terminators in the intranet
3. Check whether there are network viruses and network attacks in the intranet
according to the situation you described, the third one is more likely, which I have encountered. When there are ARP attacks and flood attacks on the intranet, it will cause network congestion, destination IP error, broadcast storm, etc., which will slow down the network speed, or even drop the line. You can grab packets and analyze the intranet traffic to see if there is abnormal traffic
arp attack is initiated from the data link layer. ARP is not a virus, but a "protocol attack". Because there is no obvious characteristic word and the important role of ARP in network communication, the anti-virus wall and firewall are helpless to deal with ARP virus. Therefore, blocking the outflow of problem data from the source and releasing legal ARP packets at the same time is the ultimate solution to completely get rid of ARP. This is e to the loopholes in the Ethernet protocol. That is why ARP attacks have been unable to be prevented after ARP firewall, antivirus software, IP-MAC binding and other traditional methods have appeared for so long. ARP firewall, antivirus software, IP-MAC binding and other traditional methods can not prevent ARP attacks
to sum up, if we want to solve ARP attacks thoroughly, we must fill the Ethernet loopholes and strengthen the underlying network security, which is the ultimate solution to get rid of ARP. It is suggested that you go online to find procts that can protect the security of the intranet and aim at the bottom of the network
the better solution I used is "immune wall gateway", which works well. It is the only solution to solve ARP attack from the root. You can try it
