WiFi sometimes disconnects, what s going on with wifi always disconnecting itself

Finish. To understand the fact, at the same distance, the ability of a mobile phone to receive wireless signals is not as strong as that of a laptop. So there are often laptop signals that are OK, but the cell phone signal is always cut off. The first thing to do is to see if it is.

The transmission power of the wireless router is too small, or the device is too far away from the router, and there is a shield in the middle (especially the wall, once the two walls are passed, the wireless signal will be weakened immediately).

Solution:1Change to a wireless router with dual antennas and strong signal; Extend the strength and range of your wireless network with two wireless routers.

2.Use the wifi sharing wizard to share the wireless network of the notebook, and the mobile phone uses the network received by the notebook, but there is a drawback, maybe when your notebook and mobile phone go to the Internet at the same time, the network speed is not good.

When I observed whether the mobile phone could access the Internet, the Internet speed was particularly fast. In this case, it is very likely that the network speed is robbed, and the neighbor or roommate is not at full speed**, cache**, which occupies a lot of network speed, and your mobile phone can't be grabbed, resulting in the computer and mobile phone being disconnected.

Solution:1Set the network speed of the wireless router and divide the network speed with others to ensure that the client can access the Internet normally.

2.Connect the network cable on the laptop, use the wired network, and then use the sharing wizard to distribute the network speed to the mobile phone, and you can access the Internet.

Wired broadband can be used, but wifi is not. In this case, observe whether there are any sources of signal interference next to the router, such as microwave ovens, cordless keyboards**, wireless mice, keyboards, magnets, etc. These devices all affect the signal.

Solution: Place the router in a different place, preferably in the middle of the house, higher and more open, so that the signal is stronger and the divergence is farther.

Observe whether it is a problem with the mobile phone settings, such as turning on the power-saving mode, and the wireless network will automatically turn off if it is not operated for 10 seconds; Another example is to turn on the Wi-Fi hibernation setting.

Solution: Turn off the power saving mode and wifi hibernation settings, select Phone Settings - Wireless & Network Settings - WLAN Settings - Advanced Settings - Keep WLAN connected in hibernation - Select Always. This measure can also solve the problem of inexplicable data consumption caused by the phone sleeping when the wifi cache** is hidden.

There is a problem with the wireless router, such as the old age and the firmware version is too low, which may cause the wireless network to be unstable and often drop.

Solution: Go online to find the latest firmware of the corresponding model and complete the firmware upgrade.

The internal hardware of the router is damaged.

Solution: Check whether the router is within the warranty period, take it to the store to upgrade the warranty, and if it is not, you can only replace it with a new one.

Reconnect the wiring.

If you are using a vivo mobile phone, the wifi will be automatically disconnected, and you can troubleshoot it according to the following methods:

6. If there is no menu option of "Reset Mesh Cavity Car Virtual Network Settings" on the mobile phone, you can go to Settings - System Management More Settings - Backup and Reset Factory Settings - Restore All Settings - Restore.

Note: Restoring all settings will not delete any data or files, only all settings of the phone will be restored, some third-party application accounts need to be logged in again, please confirm that it does not affect the use of the software before operating. For the security of mobile phone data, it is recommended to back up mobile phone data in advance before operation.

You can go to the cloud service - device cloud backup - backup data type - system data - return - backup immediately 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. If the above methods cannot be solved, please back up your mobile phone data in advance, and bring your mobile phone and purchase voucher to vivo customer service center. Detect.

Causes

1. Signal congestion.

WiFi is like a radio station, the same radio station uses the same band. In other words, the more Wi-Fi transceivers around the user, the greater the impact on the Wi-Fi network signal. In addition to the router itself, mobile phones, wireless**, microwaves, Bluetooth and other devices can be the cause of congestion.

2. It is impossible to send and receive at the same time.

The WiFi signal cannot send and receive data at the same time, which will inevitably cause data delays. Therefore, many people use the same WiFi channel at the same time, which will inevitably greatly affect the signal strength of WiFi.

Wi-Fi (pronunciation: wafa, French pronunciation: wifi) Cong Rang Tease, also known as "mobile hotspot" in Chinese, is a trademark of the Wi-Fi Alliance manufacturer as a brand certification for products, is a standard wireless LAN technology.

Due to the close relationship between the two systems, Wi-Fi is often used as a synonym for IEEE standards. "Wi-Fi" is often written as "WiFi" or "WiFi", but they are not recognized by the Wi-Fi Alliance.

Not every product that matches the IEEE applies for Wi-Fi Alliance certification, and a product that lacks Wi-Fi certification does not necessarily mean that it is not compatible with Wi-Fi devices.

If you are using a Huawei Handluyan device and the Wi-Fi connection occurs from time to time, please perform the following attempts:

1.Confirm that your Wi-Fi signal is good.

After restarting your phone, pull down the notification bar, press and hold the Wi-Fi icon, and check and hold the Wi-Fi interface. If the signal is weak, it is normal for the phone to be disconnected and reconnected, and it is recommended that you move to a place with a better signal.

2.Please restart, reset, or upgrade your router to make a noise.

Please check whether the same situation occurs on nearby mobile phones using the same Wi-Fi network, if the same situation occurs, it may be that the router is abnormal.

It is recommended that you restart the router or reset the router or upgrade the router version after trying (upgrade the router version: Generally, click "Software Upgrade" on the router settings interface, and upgrade to the latest version through "**Kai Cover Upgrade" or "Local Upgrade".) For specific router settings and upgrade operations, please consult the router equipment provider).

3.It is recommended that you set your Wi-Fi to sleep and always maintain Wi-Fi connectivity.

If your phone's Wi-Fi network is disconnected when it is standby and the network is reconnected when the screen is on, you can set the Wi-Fi to always maintain the Wi-Fi connection in the hibernation state as follows:

4.Reset network settings attempt.

If the above methods still do not solve your problem, we recommend that you back up your data in advance (third-party applications such as QQ and WeChat must be backed up separately) and bring your purchase voucher to a nearby Huawei Customer Service Center for maintenance.

Make an appointment for service. Boarding service.

Repair spare parts** inquiry.

This is because the network speed of wifi is not good, and sometimes because of the problem of wifi network speed, some ** consume a large amount of traffic, which can only be seen with mobile traffic, but can not be seen with wifi.

Sometimes the wifi signal is obviously very strong, but when the Internet is disconnected, you have to reopen the settings and connect again, and then the connection is disconnected after a while. The signal is unstable, I can't open the web page, I always drop the line, and I cry in front of the computer every minute. Today, I will take you to see the reasons behind the always falling off the land line of wifi.

1. Signal interference.

Mobile phones, wireless**, microwave ovens, and electrical appliances with wifi modules are all strong sources of signal interference, and the wireless signals and strong magnetic fields emitted will seriously affect the transmission and reception of the router's wifi signal, and even the neighbor's router will interfere with the signal noise. So, turn off these devices, or install the router in a place with less interference.

2. Poor placement.

Many people feel that the router will affect the overall appearance of the room, and they like to put it behind the TV cabinet, or in a corner. No matter how strong the signal is, it will be weakened by a wall or obstacle. If it is a duplex or a three-bedroom or two-living room apartment, it is best to have the router in the center of the house, so that the high-quality wifi signal can cover every corner of the home.

3. Poor heat dissipation.

If the router works for a long time, it will overheat, age, and overdose, resulting in reduced signal coverage. You don't need much rest time, just set the router to automatically restart every day, and the router after a little rest can make your wifi faster and more stable!

4. The channel is congested.

When using a wireless router, the router usually has a default channel, which is perhaps the most congested of them. In addition, wireless routers are now installed in almost every household, and these routers can interfere with each other, causing channel congestion and poor signal quality. But in fact, there are many router channels, you only need to change the channel in the router settings, and switch your own wifi channel to a less congested channel.

Hello, sometimes it's because of an unstable network, and sometimes it's because of a router problem! Generally, as long as the power supply of the router is turned off, it can be connected after turning it on. The steps to restore the wifi are as follows:

1. Disconnect the network and reconnect again, it may be that the phone has been dormant for too long and you have disconnected the network.

2. Restart the router. The method of restarting the router is also very simple and rude, just unplug it and reconnect it.

3. It is also possible that the wifi password has been leaked, and there are too many people connected, which in turn overburdens the router, resulting in a very slow network transmission speed. Just change the password again.

4. Select the Wi-Fi option.

5. Enter the password we want to change in the "Share Password" field below. Return.

6. After you are sure, just reactivate it directly.

iphone11wifi is always automatically disconnected, and the problem can be solved by switching and setting the network through the local area network.

1. First of all, in the center of Apple's Sunpin mobile phone, select the setting function.

2. Then in the settings page that opens, click Wi-Fi.

3. Automatically join the hotspot.

4. Finally, in the page that opens, click to select Yinkaishan Automatic, it will automatically join the hotspot, and it will not always be disconnected.

There are many reasons why wifi automatically disconnects:

3. The AP password has been changed, see if the prompt is incorrect;

4. Whether your own soft difference is abnormal, Zheng Zhi restarts WiFi5, AP is abnormal, restart AP

This is usually a routing problem or an unstable network.
