Anonymous users2024-02-11The ** of the cable terminal is about one or two hundred yuan per set, and the expensive one is several hundred yuan. Different types of cable terminations are also different. In terms of categories, 1. According to the installation material, it is divided into heat shrinkable cable termination and cold shrinkable cable termination.
2. According to the working voltage, it is divided into 1kV cable head, 10kV cable head, cable head, 35kV cable head, 66kV cable head, 110kV cable head, 138kV cable head, and 220kV cable head. 3. According to the conditions of use, it is divided into indoor cable termination head and outdoor cable termination head. 4. According to the number of cores, it is divided into single-core terminal head, two-core terminal head, three-core terminal head, four-core terminal head (which is also divided into four-core and 3+1), and five-core terminal head (which is divided into five-core terminal, 3+2 and 4+1).

Anonymous users2024-02-10When surfing the Internet, it is recommended to reinsert the network card or reinstall the driver and try again, and pay attention to whether the network cable and network card interface are normal, you can try to change the network cable.
In addition, if there is a problem with the working mode of the network card, it will also affect the use, you can find the "My Computer" icon of the computer, right-click, select "Management - Device Manager - Point to the Network Adapter", find the network card, and then right-click the network card, in "Properties--- Advanced - mediatype or link speed", set the working mode of the network card to 10m half-duplex.

Anonymous users2024-02-09I think someone is playing tricks, if it's a network card problem, then in general, either you can get on, or you can't, and the situation of dropping the line after a while is likely to be artificial.
It is speculated that someone is using the black software to attack your network card, and when your MAC address is detected, it will be T-dropped.
Think about whether you share the Internet with others, whether your friends who are online with you are in the same situation, if you are the only one doing this, then this is a targeted attack.
Remember to fix bugs and install anti-virus software, it is dangerous to surf the Internet naked.

Anonymous users2024-02-07The network card device is not disabled, but the network cable is unplugged, hello, dear, I am very happy to be able to answer for you1, due to the magnetic field or magnetic interference near the network cable interface, the computer network is unstable, the computer will prompt the network cable to be unplugged. Solution: Call ** to the local network access provider and ask them to send someone to detect it, and the problem can be solved by accessing the network cable through a non-interference place.
2. The ARP virus causes serious packet loss in the LAN network, causing the computer to prompt the cable to be unplugged. Solution: Find professional ARP interception software to intercept and apply NIC binding technology to solve the packet loss caused by ARP to the LAN.
3. The aging of the network cable or the crystal head at both ends of the network cable, the oxidation phenomenon or the quality of the network cable and the production of the network cable cause the computer to prompt the cable to be pulled out. Solution: 1) Aging of network cables:
In the daily use of the network cable for a long time, the network cable will be aged, in this case, the data transmission is often abnormal, such a phenomenon can be solved by choosing a better network cable. Hope it helps!

Anonymous users2024-02-06Based on the completeness of the question, guess what you actually need to know is:
The network cable is plugged in, the settings are normal, the computer network icon is abnormal (display) or the network cable is not plugged in, the reasons are speculated to be as follows
The message indicates that the network cable is not plugged in, and the line from the computer network port to the uplink device is loose or disconnected.
The line connection is normal, and the network icon is played, which may be a wireless network signal type and compatibility problem, and you can modify the wireless type.
Set the problem, disable the network card, uninstall it and then update it again, and check whether it is restored after resetting.
If there is an uplink problem, connect another terminal device to the same uplink device to check whether the network is normal.

Anonymous users2024-02-041. Check whether the network cable is too long and more than 50 meters, and whether there is a contact in the middle, resulting in signal transmission attenuation.
2. Change the network cable for testing, 3. Change the working mode of the network card for testing, first find the online neighbor or network of the desktop; Then right-click – Properties; Find a local connection; Then the properties and then the point Configuration; Then point Advanced; Then select network connection and duplex mode; Here you can choose the working mode, generally choose 10m full-duplex or half-duplex, according to your own computer configuration settings, you can test each one, until you solve your own computer problems.
4. If it still doesn't work, replace the computer to test and rule out the problem of the computer network card.

Nowadays, the computer generally comes with its own network card, and you also need to go to telecommunications, Netcom or move to the hall to handle broadband before you can access the Internet, this broadband can be wire-pulled, or you can choose wireless, because you choose the package traffic or package duration, the cost is different. The wireless one is like a mobile phone card.
