The network is unstable and often drops the connection, who gives an opinion

Reasons: 1. Cats may have a long service life and poor heat dissipation.

Solution: Replace the cat with a new one or add a fan to the cat.

2. It may be because the broadband provider is maintaining the line.

Solution: Consult your broadband provider for the cause and solution, and wait for the broadband provider to solve the problem.

3. The network line in the area is aging, which affects the network transmission and dispatch.

Solution: Replace the network cable.

What should I do if the wifi speed is very slow?

Sometimes it is not the problem of the network, but the abnormality of the computer's network card and other reasons, and because of the many computer systems and different network equipment menus, many people do not know the problem of detecting the network disconnection.

1. The wired network is unstable

The way to access the Internet of the wired network is to plug the network cable into the home (here is also divided into ADSL and optical fiber network, the former needs to dial up the network, the latter plugs and plays, if the dial-up will also be wrong) directly into the network port of the computer, which is generally suitable for desktop computers (fixed in a certain place). Start Run input: Press enter to open the network connection.

2. Right-click the local connection (if not, it is caused by factors such as the network card driver not installed) Property Network configuration.

3. NIC properties (different devices, different menus.)

Key points: The default is the auto-negotiation mode, that is to say, the system determines what mode the NIC device uses, if the system misjudges, the network will often be disconnected, and sometimes after detection, it will automatically connect to the network.

4. Speed&Duplex Click the drop-down menu arrow on the right and select 10Mbps Half Duplex OK.

Reason for setting: The reason why the mode needs to be changed is that the mode is customized by the user, so as not to make a clever misjudgment by the system. Of course, if it is abnormal, you can still return to auto-negotiation mode, and you can even try other modes (all of which are reversible).

5. If the NIC device menu is in Chinese, the setting is more convenient:

Start Control Panel System Device Manager Network Adapter Wired NIC Device Properties Advanced Properties Speed and Duplex 10Mbps Half-Duplex OK.

6. Some network card devices also have a power-saving mode, which is generally used for laptops (to save power), if the desktop or notebook is plugged into the power adapter, the power-saving mode can be canceled. Here's how to set it up:

Start Control Panel System Device Manager Network Adapter Wired NIC Device Properties Power Management Remove Check OK before allowing the computer to shut down this device to conserve power.

If you are in an environment where you need to plug and unplug the network cable frequently, and the network is unstable due to loosening between the plug and the base, you can use a double-sided sticker to attach a piece of cardboard to it (the side without copper sheets) to increase the contact force and ensure that the line is in good contact.

If you mean that the broadband frequently drops the solution, here's how to do it:

1. If you use a router, disconnect the router for stand-alone dial-up test;

2. If you have a modem device, please pay attention to whether the device is overheated, and it is recommended to turn it off for a few minutes before restarting it.

3. If the connection is dropped when running the program alone (such as when playing a game), it is recommended to restart the computer or reinstall the program;

4. Check whether there is a disconnection caused by a computer virus, and it is recommended to scan the whole disk;

5. If there is a server to choose from the running program, please select China Unicom.

1: Check whether it is your own problem, use the run input cmd command, enter ipconfig all to check the DNS server, if the computer can't see here, open your router, there will be a display on it, and perform a long ping -t to test the DNS server.

3: If it still doesn't work, it proves that it is a problem with the ISP** business, and you need to contact the broadband provider to solve it.

There is no better way to contact the operator, call customer service, or change one, not your own reasons.

Look at the wrong line sequence at both ends of the network cable, yes, if it's wrong, the packet loss is delayed.

If you exclude the network bandwidth being occupied, it may be a problem with your router settings, because the settings are default, not the settings that are suitable for your environment!!
