The network is always unconnected, or always disconnected. What s with?

1. Check the wifi signal of your mobile phone.

Please check whether the wifi signal strength in the status bar of the mobile phone is weak, if it is weak, please move the mobile phone to a high position or use other mobile phones to connect to this wifi for comparison.

2. Check the router settings.

Please check the router manual, enter the router settings, and check whether to set dual-band or multi-band in one, if so, it is recommended to turn it off and try again.

3. Check your phone settings.

In Settings --Wi-Fi --Advanced Settings --WiFi Hibernation, change the WLAN hibernation policy to "Never sleep".

Note: Android 10 and above models do not support setting the WiFi hibernation policy.

4. If the application consumes more power in the background, the system will intelligently control the background power consumption to save power, which will affect the application networking, you can enter Settings - Battery - Background Power Consumption Management - Find the corresponding software - Allow high power consumption in the background.

5. Reset the network settings.

Resetting network settings will delete the connection records of WLAN, mobile data network, Bluetooth and other networks, you can go to Settings - System Management - Backup and Reset - Reset Network Settings - Reset Settings - Follow the prompts (you need to select the corresponding SIM card when dual SIM).

1. Enter the cloud service - data synchronization - turn on WLAN, Bluetooth, etc. to synchronize data to the cloud service.

2. Go to "Cloud Service" -- Device Cloud Backup -- Backup Data Type -- Open "System Data" -- Return to the previous page -- Back up now, and back up some system settings data.

6. Reset all settings (do this when you can't see the reset network settings menu).

This action does not delete the software or files, only resets all the settings; For data security, you can back up important data before operation.

Note: Go to Cloud Service - Device Cloud Backup - Backup Data Type - System Data - Return - Back to Back Up Now to back up some system settings and desktop layout; Cloud service--Data synchronization--Turn on WLAN, Bluetooth, etc. to synchronize data to cloud service.

7. Service center testing.

If the above methods fail to help recover, the customer service center needs to detect and process, the customer service center address: enter the vivo official website vivo**app--my--service outlets after-sales outlets--select the province and city to query the customer service center address;

Tips: It is recommended to bring relevant purchase vouchers (such as: purchase invoice, warranty card, ID card) when you go, and the staff of the consulting service center in advance, and the hail protection staff will go again during normal working hours to avoid empty running, and call Qingfan on the way to and from the sail to pay attention to safety.

Frequent disconnections in your home's wireless network are the cause of signal interference. There may be strong sources of signal interference next to the router, such as microwave ovens, cordless ovens**, magnets, high-voltage wires, etc.

The wireless signals emitted by these devices and the strong magnetic field will seriously affect the normal transmission and reception of the router's wifi signal.

It is also possible that the wifi function of the mobile phone is buggy. There may be bugs in the design of individual mobile phone wifi software, such as turning on the power saving mode, which causes the mobile phone wifi to automatically turn off when idle. Or it has compatibility problems with Zen routers, causing other wifi devices to drop down.

The wifi transmission power of the router is too small, or the Qiyu device is too far away from the router, and there is a shield in the middle. If the wifi signal is too weak, it will also drop from time to time.

There are many reasons for this, in addition to the peak of Internet access, if the hardware and software do not meet the following conditions, it may lead to the interruption of the search. For example, there is no electromagnetic interference around the computer and its auxiliary equipment and the transmission part, especially the interference of the welding machine and the frequent start of large loads on the equipment.

Effective power cord cross-section; Comply with the safety insulation level specified in the national standard. The temperature of drying and ventilation is suitable, the dust particle size is small, and the walls and roofs are best painted.

Introduction: A network is composed of nodes and connections, which represent many objects and their interconnections. Mathematically, a network is a type of graph, and it is generally considered to refer specifically to a weighted graph.

In addition to the mathematical definition, a network has a specific physical meaning, that is, a network is a model abstracted from some kind of practical problem of the same type. In the field of computer, the network is a virtual platform for information transmission, reception and sharing, through which the information of various points, surfaces and bodies is linked together, so as to realize the sharing of these resources.

History of the Internet:

The development of China's Internet was marked by the first e-mail sent to the world in 1987 through the Chinese academic network Canet. After decades of development, four mainstream network systems have been formed. Namely:

the Chinese Academy of Sciences' science and technology network CSTNET; CERNET, the Ministry of Education's education and research network; Chinanet of the former Ministry of Posts and Telecommunications and ChinaGBN of Jinqiao of the former Ministry of Electronics Code Hole.

Expansion: With the expansion of the Internet around the world, China's Internet has developed rapidly, and in recent years, the number of ISPs in China has been increasing, and the services provided have also been continuously enriched. However, in order to achieve the prosperity of China's Internet services, it is not only necessary for more and more Internet service providers to provide rich services, but also for Internet service provider ISPs to continue to develop the service market, adopt flexible operation models, find their own ways to make profits, continuously improve their independent innovation capabilities, and enhance their core competitiveness.
