Suddenly I can t connect to the wifi, and the wifi suddenly can t connect

1. Personal network connection (such as home network, company network).

3.Power off and back on the router and try to connect;

4.Reset the router to factory settings, set it up again, and try to connect again (press and hold the factory reset button, please refer to the router manual for details).

5.If access is denied when you connect:

It is recommended to confirm whether the MAC address filtering function (blacklist and whitelist) is enabled on the router, and restart the router after setting it again. The router MAC address filter setting path is generally as follows: router management interface - wireless settings - MAC address filtering, add your mobile phone MAC address to the allowed MAC address access list or remove it from the prohibited MAC address access list, there may be differences in the settings path of different routers, but the name of the setting item is roughly the same, if you can't find it, please refer to the router manual or consult the customer service of the equipment provider.

Reminder: and above mobile phones will use different random MAC addresses by default, if the router has set up a black and white list, please set up the device MAC connection on the mobile phone.

1) The number of connected users may be too large, please disconnect other connected devices and try to reconnect to the WLAN.

2) Restart your router, turn off and on Wi-Fi, or try restarting your phone to connect in.

3) Try to set a static IP, please long press the hotspot name, click Modify Network > Show Advanced Options > IP > Static.

7.If the connection message is full, the maximum number of Wi-Fi hotspots has been reached, and we recommend that you use another network connection.

2. Free public internet access (shopping malls, banks, etc.) is not available

1.Please enter the Wi-Fi search interface, click or press and hold the Wi-Fi network name, select not to save and then click to connect again, under normal circumstances, the phone will automatically pop up the verification page, follow the page prompts, and you can use it normally after completing the verification.

2.If the verification page can't pop up, you can do the following:

1) Close the browser and reopen it, click on any webpage and try again.

2) It is recommended that you enter " in the page address to see if the authentication page can be popped up.

4) Long press the Wi-Fi network, select Modify Network, check Show advanced options, and use the device MAC connection attempt.

3.If you still can't connect after successful verification, the number of public network connections may be too high, and we recommend that you use the mobile network temporarily.

Suddenly I can't connect to the wifi. You can try turning on and off the wifi function of your phone a few more times. If you still can't connect, you can restart your phone and try if it still can't connect, you can turn off the router first, turn off the network, and then restart the network and router.

Can I connect to wifi? Sometimes turn off these networks and routers for more than ten minutes, and then restart them to connect to the wireless network, if you still can't connect to the network, it may be a problem with the network operator, you need to contact the network operator to ask.

You can check how to check how your phone can't connect to wifi

1. It is recommended to click when entering the password"Eye icon"to display the password and make sure that the password is correct.

Note: When the mobile phone wifi password is entered, if the 8-digit number is not full, the "connection" function will be grayed out.

2. Please go to Settings --WLAN, click on the wifi you need to connect to, and click"Forgot Network Forgot password"reconnect.

3. Please go to the mobile phone settings - WLAN - click on the right side of the connected wifi - privacy, and check whether the MAC is set to "use random MAC (default)", if so, it needs to be set to "use device MAC".

4. Please compare whether it is normal for other mobile phones to connect to the same wifi, and confirm whether it is wifi or mobile phone. If it is due to Wi-Fi, please restart the wireless router to check. At the same time, you can enter the router management interface to check whether there are special functions

Such as the number of connections limit, Internet time management, etc.

5. Go to Settings - System Management - Backup and Reset - Reset Network Settings - Reset Settings, and then use to view. Turn the wifi off and on again, or turn it off and restart the phone. I can't tell what the specific reason for this phenomenon is, it is very likely that the phenomenon of wireless connection of the mobile phone will occur after a long period of use, which may be due to the temporary inability to connect due to the stuck of the system, and the mobile phone wifi will be turned on again to try whether it can be connected.

You can carefully observe what prompts the phone cannot connect to the wifi, or the step where the wifi device cannot be connected. If you are always in the process of obtaining an IP address, it is generally because your WiFi device is connected to too many devices, resulting in the inability to connect.

There is interference in the wireless wifi signal, which is also very common and is likely to cause too many nearby wifi signals, resulting in the problem of wifi signal channel interference. For this kind of problem, it is generally necessary to change the channel of your router.

Wireless wifi password is wrong, for this case, when the mobile phone is connected to wifi, if the wifi password is changed, then it will generally prompt the wifi password is wrong, verify the identity, but there are also mobile phones will not prompt.

If you can't connect, check whether the router is normal first, and if it doesn't work, change it. If you can connect to the Internet and can't access the Internet, just ask the network operator.

The reasons why WiFi suddenly cannot be connected are: the password is wrong and you can't connect to WiFi, the SSID number of the wireless router, and the router is wrong.

1. The wrong password causes you to be unable to connect to the wifi

The problem of not being able to connect to the wifi due to the wrong password occurs here, and the problem that most users cannot connect to the wifi wireless network occurs here, especially pay attention to uppercase and lowercase letters or symbols. If you enter the first code incorrectly, you can confirm the password again and re-enter the password, and connect.

2. The SSID number of the wireless router.

If the computer can be connected to the net, but the mobile phone can't, check the SSID number of the wireless router. If it is letters and numbers, mobile phones sometimes cannot effectively recognize Chinese.

3. There is an error on the router.

If there is an error on the router that prevents you from connecting to WiFi, restart the router and reset the password to connect again.

Precautions for using wifi:

1.When using free public wifi in public places, you must consult the management personnel of public places to make sure that the name of the wifi is correct, so as not to fall into the trap of hackers.

2.Set up a manual connection to wifi to prevent some phones from automatically looking for a network and connecting automatically.

3.Install anti-virus software on your phone to prevent criminals from taking advantage of it.

4.When using public wifi, you can take a look at ** and news, and try not to perform sensitive operations and payment operations, so that Rongniandong is easy to leak your account password. If a payment must be made.

5.When using public WiFi, if you are asked to click on some advertising links or ** some apps or share some personal information, be vigilant, these operations are more likely to contain traps. <>

1.It should be the password, and someone changed it. Otherwise, it's a matter of DCHP allocating IP. Re-modified, wifi password and router access password.

2.It is recommended to reboot the router and reconfigure it, if it still doesn't work, there may be a problem with the router.

3.Look to see if there are physical walls, metal meshes, etc., between the computer and the router line, as these things can weaken the signal.

In addition, you can log in to the router and change the channels in it from "automatic" to fixed mode, such as "channel 1", channel 2, etc.

4.It may be that the connection with the router is unstable because of a slight difference in the acceptance frequency, and there happens to be a suitable frequency for your computer around at this time, so it will be connected to this route first, and you don't have a password, so you can't connect successfully.

The friend above stole my answer...

Friend. I hope it can help you, remember to, satisfied, thank you...

See if the sect is in arrears.

The reason for suddenly not connecting to wifi may be a faulty router, multiple devices connected at the same time, exceeding the coverage of the signal file, or a faulty wireless network card.

The mobile phone cannot connect to wifi is generally caused by abnormal mobile phone network settings, or the mobile phone does not turn on the wifi function at all. Router malfunction, this is one of the most common causes of problems, when the phone cannot connect to Wiifi, most of it can be attributed to the damage of the router. Of course, it is also possible that the router is stuck in an endless loop for a short time.

Then the solution is to directly unplug the interface of the router and restart.

Introduction to wifi:

Also known as Hejizuo Mobile Hotspot in Chinese, it is a trademark of the Wi-Fi Alliance manufacturer as a brand certification for the product, and is a wireless LAN technology created in standards. Due to the close relationship between the two systems, Wi-Fi is often used as a synonym for standards. Wi-Fi is often written as WiFi or WiFi, but they are not endorsed by the Wi-Fi Alliance.

Not every matching product applies for Wi-Fi Alliance certification, and a relatively lack of Wi-Fi certification does not necessarily mean that the device is not compatible with Wi-Fi devices.

devices are installed in many products on the market, such as: personal computers, game consoles, smartphones, tablets, printers, laptops, and other peripherals that can be connected to the Internet wirelessly. <>

When wifi suddenly fails to connect, there may be several common reasons and solutions:1Network Failure:

First of all, check if other devices can't connect to wifi either, if other devices can't connect either, it may be that the network is malfunctioning. Try restarting your WiFi router and modem, wait for a while, and try to connect again. 2.

Weak signal or too far away: If you are too far away from the WiFi router or outside of the signal range, it can cause connection problems. Move closer to the router or try to minimize obstructions between the router and the device.

3.Incorrect WiFi settings: Check your device's WiFi settings to make sure you have entered your WiFi password correctly.

If you've ever changed your router's settings, make sure your device is using the correct WiFi name (SSID). 4.Router Issues:

Check if your wifi router is working properly. You can try connecting other devices, if other devices can't connect either, it may be a problem with your router. You can try restarting your router, or contact your network service provider to resolve the issue.

5.Device issues: If only one device can't connect to wifi while others can, then there may be a problem with that device.

Try restarting the device, or check your device's wifi settings, update your device's drivers or operating system. If the issue persists, it is recommended to contact your network service provider or technical support team for further assistance and guidance. <>

The sudden failure to connect to the wifi may be caused by the combination of multiple boring reasons. One possible reason is an issue with the wireless router itself. Over time, a wireless router may experience hardware failures or software vulnerabilities that cause it to no longer be able to provide a reliable WiFi signal.

Another possible reason is a network issue. Sometimes, there is a problem with the network, resulting in the inability to connect to the internet. This can be due to ISP (Internet Service Provider) service outages, equipment failures, network overloads, or other reasons.

There is also a possible reason for the device issue. If your device has a software glitch or hardware failure, it may not be able to connect to the WiFi network. Sometimes restarting your device can help resolve the issue, but if the problem persists, you may need to do more advanced repairs or replace your device.

Continuing to delve into other possible causes of wifi connection issues, there is also a very common problem of the distance between the router and the device. If the distance between your hooded router and the device is too far, the WiFi signal will become very weak or even disappear completely, causing connection problems.

After ruling out other causes, the last possible cause is electromagnetic interference in your network. Electromagnetic interference is caused by interference with electromagnetic signals generated by household appliances and other devices. These interfering signals can interfere with your wifi signal and cause connectivity issues.

To sum up, the sudden failure of wifi connection can be caused by a variety of reasons such as wireless routers, network issues, device issues, distance, and electromagnetic interference. If your wifi connection doesn't work, you can try restarting your router, getting closer to the router or trying to find a different network. If these methods don't resolve the issue, you may need more in-depth troubleshooting or seek professional technical support to help you resolve the issue.
