What is the reason for the exclamation mark next to the wifi

If you are using a vivo phone, there is an exclamation mark next to the wifi signal icon indicating that the current wifi signal of the mobile phone is not in the best state, it is recommended to move the mobile phone closer to the wifi signal source or change the wifi connection.

An exclamation mark appears next to the Wi-Fi icon of the mobile phone to indicate that the mobile phone can connect to Wi-Fi, but it is currently faulty and cannot connect to the Internet through this Wi-Fi; You can see if it's a phone or wifi problem by eliminating it. Here's how to fix it:

1. An exclamation mark is displayed next to the mobile phone when it is Wi-Fi, which means that the mobile phone is connected to Wi-Fi but has no network access;

2. This may be due to the network connection problem of the wifi itself, which can connect the device normally but does not connect to the Internet correctly;

3. If other devices can connect normally, it may be because the wifi has turned on the connection settings, which restricts the connection access of your current device.

An exclamation mark indicates that the phone is connected to WiFi but has no network access.

The reasons why the mobile phone is connected to wifi but there is no network access are:

1. The wifi itself is a problem, the wifi may not be connected normally, resulting in the inability to access the Internet;

2. Router problems, the router may be overheated or damaged;

3. There may be broadband arrears, resulting in inability to access the Internet;

4. The wifi name contains Chinese, resulting in some mobile phones unable to connect to the Internet;

5. There may be a problem with the mobile phone system, which may cause the connection to wifi but the Internet cannot be accessed.

Suggested workaround:

1. Use other mobile phones or devices to connect to wifi to try whether you can access the Internet and rule out the problem of wifi itself;

2. Restart the router to try, or restore the router to factory settings, then dial up the Internet again, and reset the wifi according to the setup wizard, or change to a new router and dial up to connect to the Internet;

3. Contact the broadband customer service to confirm whether the broadband is abnormal, such as arrears, recharge the broadband, and then dial up the connection;

4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting;

5. If the above reasons are ruled out, it is likely to be a problem with the mobile phone system for a long time, it is recommended to restore the factory settings or flash the phone to see if it can solve the problem.

A Huawei P9Plus phone I bought in 2016. It's exactly the same as you. It's a phone hardware issue. There is only one way to fix it: back up all the data and restart.

If you are currently using a vivo mobile phone, there is an exclamation mark next to the wifi signal icon, indicating that the current wifi signal of the mobile phone is not in the best state, it is recommended that you move the mobile phone closer to the wifi signal source or change the wifi connection.

If the Internet access function is not affected when the exclamation mark is displayed, this is due to the display error caused by the server abnormality, and you can resume normal use after restarting your phone.

If you are using a Huawei phone and an exclamation mark icon is displayed when you connect to Wi-Fi, you can perform the following methods to troubleshoot the operation:

1. Wi-Fi displays an exclamation mark icon, but you can surf the Internet normally.

1.Mobile data services display up and down arrows.

When the Wi-Fi network is unavailable, the phone will automatically switch to mobile data to surf the Internet, and the mobile data icon will display up and down arrows, and the Wi-Fi icon will display an exclamation mark.

2.Mobile data services are turned off and no up and down arrows are displayed.

It may be that the display is abnormal, and it is recommended that you reconnect to Wi-Fi or restart your phone to see if it can be restored. If the problem persists, we recommend that you back up important data in advance (third-party communication apps need to be backed up separately) and bring your purchase voucher to the Huawei Customer Service Center for testing.

2. The WLAN displays an exclamation mark icon indicating that the network is unavailable.

1.Please restart the router and try again.

2.Please reset the cellular settings and try again: Open Settings, enter Reset Network Settings in the search bar, and click Reset Network Settings. (This action deletes the connection records for WLAN and Bluetooth).

If the above methods do not solve your problem, it is recommended that you back up your data (third-party communication applications need to be backed up separately) and bring the purchase voucher to the customer service center for testing.

Hello, if you turn on the Wi-Fi after the display next to one! Then it is very big, it may be because the network is not normal, and it cannot be connected normally.

It is recommended that you can turn off the wireless network, turn it back on later, and then check whether this kind of problem still occurs, if there is still such a problem, then it is your network quality problem, and you need to check the network quality.

This is the wifi signal exists, but can not access the Internet normally, this phenomenon may be the router connection is normal, but the network broadband modem is not turned on, or the network is not normal.

In this case, it means that there is no network signal and you cannot access the Internet. The network cable is not plugged in, or there is a problem with the carrier.

The production process of electricity is extremely complex, with multiple processes such as power generation, transmission, distribution, and consumption. Among them, power generation refers to the place where electric energy is produced, such as: thermal power units, hydropower units, etc.; Transmission refers to the operation of using high-voltage lines to complete power transmission; Substation refers to the use of high-voltage substation to convert high-voltage voltage, ultra-high-voltage voltage and other electrical energy into low-voltage electrical energy; Distribution is the final step, which reduces the voltage and delivers the electricity to the consumer.

The power transmission and transformation project of the power system attaches importance to the two steps of transmission and transformation. With the rapid increase in China's electricity demand, there is an urgent need for power system transmission and transformation projects to undertake the transmission and transmission of the power system. A number of power transmission and transformation projects together constitute the main frame of China's power grid.

At this stage, China's power transmission and transformation projects generally have multiple voltage levels such as 110kv, 220kv, 330kv, 500kv, etc., of which 220kv is used more frequently in China; 330kV is commonly found in China's northwest power grid; The 500kV level is the highest, and the requirements for cost, capacity, and process are higher and more advanced. At present, China attaches great importance to the construction of 500kV power grid, which is the backbone of China's power grid. Power transmission and transformation engineering is an important engineering project in the construction of the main grid of the power grid, including transmission line engineering and substation engineering, which requires high costs, extremely complex engineering construction, and high construction technical requirements.

Power transmission and transformation projects generally include electrical installation, communication and automation, civil engineering, electrical equipment commissioning, system start-up and commissioning, etc. Among them, electrical installation includes the installation of primary equipment such as high-voltage equipment, and also includes the wiring and installation of secondary equipment such as protection and control systems; Communication and automation refers to communication engineering and substation automation; Civil engineering covers equipment foundation, building engineering, four-way and one-level, frame foundation, etc.; The commissioning of electrical equipment is to test and adjust the installed primary equipment and secondary equipment; System start-up and commissioning refers to the start-up and commissioning of the operation of transmission lines and substations after the construction of power transmission and transformation projects. The status quo of power system power transmission and transformation project management does not pay attention to the coordination of the project scheduleThe power system power transmission and transformation project is very different from other projects, and the requirements of the power system power transmission and transformation project are higher, and the construction progress is required to be carried out in strict accordance with the specified requirements to ensure that the project construction is completed on time.

At this stage, most of China's power enterprises do not pay attention to the management and coordination of the progress of power transmission and transformation projects, which seriously affects the quality of the project, which not only reduces the ability of construction personnel and engineers to control the progress of the project, but also has a great impact on the efficiency and quality of the project. A small number of power transmission and transformation projects only pay attention to the progress of the project, and lack the supervision of the project quality, resulting in the problem of urban power shortage.

If you use a vivo mobile phone, there is an exclamation mark next to the wifi signal icon, indicating that the wifi network currently connected to the device is not available, it is recommended to try to keep the device closer to the wifi signal source or connect to other wifi networks.

The phone is connected to wifi normally but can't access the internet:

1. Check your phone's settings.

Go to Settings --WLAN and check if the wifi has been successfully connected.

Go to Settings - Other Networks & Connections - Private DNS to see if Private DNS is set, if so, it is recommended to set Private DNS to off and try again.

2. Check WiFi

Please compare whether the same wifi connection is normal with other mobile phones, and confirm whether it is the wifi or mobile phone. If it is due to Wi-Fi, please restart the wireless router to check. Some public Wi-Fi networks require browser authentication before they can connect to the Internet.

3. Check the network permissions.

Please go to iButler - Traffic Management Traffic Monitoring - Network Management - WLAN - Turn on the software networking group infiltration permission.

4. Check the environmental causes.

If the phone is far away from the router, although it shows a WiFi signal, it may not be able to access the Internet, it is recommended to adjust the distance between the phone and the router before trying.

5. Reset the network settings.

Make a backup of wifi and other data, go to Settings - System Management - Backup and Reset - Reset Network Settings - Reset Settings, and then use it to view.

Note: Resetting the network settings will clear the connection records such as Wi-Fi, mobile data network, Bluetooth, etc.; If you have dual SIM, you need to select the corresponding SIM card.

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

Note: This action will not delete the software or files, only reset all the settings; For the sake of data security, important data can be prepared before operation.

7. Service center testing.

If the above methods do not solve the problem, please back up your mobile phone data in advance, and bring your mobile phone and purchase voucher to vivo customer service center for testing.
