Suddenly the network can t connect to the network, suddenly can t connect to the network

Workaround for the router suddenly unable to connect to the network:

1. First of all, check whether it is due to the sudden drop of the main line or the cat's line. In this way, although there is a routing signal, you still can't access the Internet.

2. Check whether it is due to the power failure of the computer room caused by the voltage instability during the peak period of electricity consumption, a friend of mine who works in Netcom said that this situation is possible, especially in small and medium-sized cities, mainly during the cooking period, and the electricity is used more, resulting in unstable voltage.

3. If it is not the voltage reason, please restart the router. Find the reset button, press and hold it for 3s to see if the problem is solved.

4. If there is no solution, you have to set up the router, enter the browser, enter the address, press enter to log in, and check the password details.

5. Click on the setup wizard and follow the prompts to set it step by step.

6. After the setting is completed, click Confirm to save, the router will restart, restart it to see if the problem is solved.

7. If there is still a problem and you can't access the Internet, then call the local service provider to ask if the service provider is faulty.

8. If the service provider is not faulty, then it is necessary to repair whether there is a problem with the router. It is recommended to go to a professional repair shop for repair.

If you are using Unicom Broadband and cannot connect to the Internet, there may be one of the following reasons:

1. If the broadband is in arrears or expires, you need to pay or renew it in time.

2. If the network cable is loose, both ends of the network cable need to be plugged in tightly.

3. If the device is used for a long time, you can turn off the power of the optical modem, router, computer and other Internet access equipment for a few seconds, and then turn on the power supply and restart.

It would be nice to try a few more times, but it was not compatible at first.

The reason for not being able to access the Internet is that the Internet speed is too slow, the wireless router used by the home has a narrow frequency band, and the mobile broadband network is said to have no server of its own. Once the network crashes, when the mobile phone wifi is connected but the Internet cannot be accessed, the server will be prompted when it is repaired by 360 Guard.

When my phone can connect to wireless wifi but can't access the Internet, I usually use 360 Guard on my computer to fix it. How to repair the network: Turn on the computer and double-click to open 360 Guard, click "First Aid for Network Disconnection" in the upper left corner, and then click "Repair Now" to repair the network.

After the repair is completed, if the network is still not able to access the Internet normally, 360 Guard will prompt "Deep Repair", and "Deep Repair" needs to restart the computer to repair, so that after repairing the network, there is no major problem with the network part.

If the network is still unable to connect to the network after the 360 Guardian network is disconnected and repaired, at this time I usually turn off the power switch of the "photoelectric cat" (that is, the fixed router configured when the network is first installed), and then wait for 1 2 minutes, and then turn the switch on again, at this time my smartphone and all other devices connected to the network can be connected to the network.

Computer (computer), commonly known as computer, is a modern electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed.

A computer that consists of a hardware system and a software system without any software installed is called bare metal. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Inventor of the computer John von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality.

Its application field has expanded from the initial military scientific research application to all fields of society, and has formed a huge computer industry, which has led to technological progress on a global scale, which has triggered profound social changes, and computers have spread all over ordinary schools, enterprises, and institutions, and have entered the homes of ordinary people, becoming an indispensable tool in the information society.

The application of computers is becoming more and more common in China, after the reform and opening up, the number of computer users in China has been rising, and the level of application has been continuously improved, especially in the fields of the Internet, communications, and many other fields.

From 1996 to 2009, the number of computer users increased from 6.3 million to 67.1 million, and the number of networked computers increased from 10,000 to 59.4 million. Internet users have reached 100 million, and there are 100 million mobile Internet users on the wireless Internet, of which 100 million mobile Internet users have access to the Internet, ranking first in the world.
