Turn off and restart the Wi-Fi connection.

Select Have your Android device ignore the network and add it again.

Manually update the password for your Wi-Fi.

Check out the Wi-Fi advanced settings.

Set a static IP address.

Disable the Wi-Fi hibernation policy.

How to do it: Turn off and restart the Wi-Fi connection.

Here's how: Open the phone menu, enter the "Settings" bar, select "Wireless & Network Settings", enter the "Wi-Fi Settings" item, select "Turn off Wi-Fi" in the new window, and after completing the shutdown operation, re-enter the item and select "Turn on Wi-Fi" to restart the Wi-Fi connection.

Select Have your Android device ignore the network and add it again.

Move outside the coverage area where you want to ignore the network, select Ignore the network, return to the coverage area, wait for the network to automatically appear, and then enter the network password to log in again.

This way the android phone can get a new address and work normally.

Manually update the password for your Wi-Fi.

Move outside the coverage area of the network in question, go to the Wi-Fi configuration item that needs to be adjusted, select "Adjust Network Settings", enter a new password in the window and review the password information, and finally select "Save password".

Set a static IP address.

In order to set a static IP address, you need to enter the information (IP address, gateway, subnet mask, DNS, etc.) in the static IP address setting field.

The only problem with setting a static IP address is that it will work on all Wi-Fis, so this method can only be solved if the user is only connected to one Wi-Fi.

Disable the Wi-Fi hibernation policy.

If Wi-Fi issues occur frequently, users should try setting the Wi-Fi hibernation policy to Never to see if the problem goes away.

If you set this policy to never, the power consumption will increase, but in another way, it will also make the Wi-Fi connection more stable.

Restore the factory settings and try it, either you will upgrade to the designated place, or the wifi module is broken These are the three possibilities.

Mine too, swiped off the machine (press the sound reduction button when you turn on the power on) and it's fine.

This data cannot be connected, which is usually caused by temporary network problems, and restarting the phone can solve the problem. Here are a few workarounds:

1. Turn on your phone, and then enter the desktop of your phone.

2. At this time, pull down the menu column, select airplane mode, turn it on, then turn it off, and reconnect to the network.

3. You can also re-register the network by restarting the phone.

Note: If the mobile phone fails through the above methods, check whether the mobile phone is within the signal coverage range or whether the mobile phone is in arrears.

1. The boot line is abnormal: use an external power supply to supply power to the mobile phone, use the electric meter to detect whether the indication has changed, if there is no change, it is likely that the boot line is broken or the boot button is not in good contact.

2. The power supply circuit of the battery is abnormal: use the external interface to supply power to the mobile phone, see if it returns to normal when it is turned on, if it is normal, it is determined that the power supply circuit of the mobile phone is abnormal.

3. The IC of the mobile phone power supply is abnormal: test the test point of the peripheral circuit of the power supply IC according to the circuit schematic diagram to see whether the test value is normal.

4. The system clock and reset of the mobile phone are abnormal: you can use the dual total oscilloscope to detect the CPU power supply of the mobile phone to check whether the waveform in the reset is correct.

5. Problems with logic circuits: that is, faults in the circuit version of mobile phones, which can generally be solved by repair welding.

6. Software conflict: The installed software does not match the system of the mobile phone, which may also cause the mobile phone to fail to boot, you can connect the mobile phone to the computer to delete the program.

7. If it is a copycat mobile phone, then I estimate that it can't be turned on because the chip inside is burned, or some of the small parts inside are loose, but this situation will only appear if you drop it, the chip burns may be because you charge it for too long, burn the chip, if the battery has electricity, that is these aspects, if it is a brand-name mobile phone, such as Nokia, Motorola. These situations are rare, unless it is artificial, if it is a brand-name smartphone, and it is not used improperly, it is a software problem, it may be a system crash, or because of the mobile phone poisoning caused by software damage, generally this can only go to the maintenance office, however, I think the biggest possibility is caused by static electricity, it is recommended that you do not open the blind repair, or go to the maintenance office!

The WLAN function that comes with the mobile phone should be damaged, but you can try other forms of connecting to wifi hotspots, such as using wifi sharing wizard, connecting around wifi hotspots, fast network speed, high stability, and never disconnected network, wifi sharing wizard is a mobile phone essential free wifi Internet software, automatically connect to free wifi hotspots around you, the software is completely free, no charge.

Hope, thank you.

You can use the following methods to troubleshoot:

1.Reset the wireless router and then connect to Observe.

2.Connect to other wireless networks to see if there is a stuck.

3.Whether you have installed Mobile Security Guard software or some third-party software programs on your phone, and if so, please try to uninstall it.

4.Restore the machine to factory settings, the operation is as follows: Settings-Reset-Factory Reset (Tips: Restoring factory settings will lose all data in the phone, it is recommended to back up important data such as **Ben,**,**, etc.).

5.Firmware upgrade attempt. (Settings - About Device - System Update) If the problem still exists through the above methods, it is recommended to go to the mobile phone repair center to check the machine for the engineer and deal with it.

Cause Analysis:

1. If you install a third-party security management software, if you have it, you can uninstall it directly, and if the mobile phone has a security center, the problem of the mobile phone crashing and stuckness will be caused by the conflict.

2. Obtain root permission normally on the development version of the system, but uninstalling some system programs or forcing root access on the stable version of the system will cause the phone to crash and get stuck;

3. Operating the mobile phone while charging will cause the battery to heat up, causing the mobile phone to crash and get stuck;

4. Using an unofficial MIUI system or swiping the wrong official MIUI version causes a crash;

5. Users buy copycat machines or refurbished machines through unofficial channels, and it is easy to crash and get stuck.
