Questions about network connectivity! Ace enter!

There may be a problem with the crystal head or magnetic field interference, and it is generally good to change the network cable. Or make a crystal head from scratch.

It may be that you have a limitation on the Internet, and they will solve it by complaining to the Ministry of Information Industry.

You check to see if there's a problem with the line.

It is a phenomenon caused by an unstable network signal.

There are many reasons for network instability, and here are a few of the more common ones:

1. Network operator issues.

At present, home networks use shared bandwidth, and your network speed can be guaranteed during off-peak periods, but during peak periods, you can't guarantee normal speeds. Especially at 8-10 o'clock in the evening, everyone likes to go online and watch movies after eating, and the Internet speed will be quite slow at this time.

2. Router reason.

If the router works for too long, the network status is unstable or even disconnected. At this time, you only need to power off, restart the router, and wait for a while to recover. For such situations, you should develop good Internet habits and turn off the power of the router in time when you don't need to go online.

3. The reason for the modem (cat).

For users who use ADSL to access the Internet, the modem (cat) working for a long time will also lead to no problems with the network or even network disconnection, which can be restored after power failure and restart. The solution is the same as the router solution, develop good Internet habits, and turn off the power in time when not in use.

4. The reason why the NIC device is working normally.

Right-click the "My Computer" icon in the system desktop, click the "Properties" command from the pop-up shortcut menu to open the system properties setting window, click the "Hardware" tab in the window, and click the "Device Manager" button in the corresponding tab page to enter the device manager window of the local workstation;

In this window, double-click the target NIC device under the branch to open the NIC settings page and click the General tab in the settings page to enter the label settings page. In Device Status on this page, the current NIC device is running normally, indicating that there is no problem with the NIC device.

5. Wireless stability.

With the development of wireless technology, laptops, smartphones, ipads, and even desktop computers can be connected to the network through wireless technology.

6. Multiple computers share the same network.

7. Trojan horses or viruses.

When the computer is infected with Trojan horses or viruses, the computer will also run slowly, the network is unstable, etc., at this time, it has nothing to do with the network, routing, etc., and the anti-virus software should be used in time to disinfect the computer to avoid unnecessary losses.
