What should I do if my mobile phone is connected to wifi without displaying icons?

1. Why is the icon not displayed when the phone is connected to WiFi?

The password for connecting the mobile phone to WiFi is correct. Can't you connect to WiFi? : 1. First, check whether the wireless router is working properly. You can use other mobile phones or digital products to connect WIFI signals. Generally speaking, this router can work normally if everyone can connect and surf the Internet normally.

2. The mobile phone is turned on and the network is turned off. Check whether the option to turn off the network is turned on when the phone is dormant. The phone will be disconnected after a period of time or may not receive background chat software. The possible reason is that the function of closing the network when sleeping is turned on by mistake.

3. If you use the router for a long time, the router may be in suspended animation. Just restart the wireless router.

4. The authentication type is not appropriate. When trying to change the authentication type of the router, it is best to choose the secure "WPA2-PSK" type mode, and the following encryption algorithm is best to choose "AES".

5. The mobile phone or router network settings are abnormal. Consider restoring router factory settings and mobile phone network settings.

2. Why isn't the wifi icon displayed on the phone's wifi connection?

If the WIFI connection is successful, but the icon cannot be displayed normally, it may be a system abnormality. Under normal circumstances, if WIFI is turned on and successfully connected, the notification bar of the mobile phone will display the WIFI icon.

It is recommended to try the following methods to solve the problem:

1. Switch the phone and wireless device again. Press and hold the network name for a long time-select Forget, turn on the mobile phone wlan, and search for a signal connection attempt.

2. Try to replace the static IP. If conditions permit, whether this phenomenon occurs in the attempt to change other routers or wireless connections.

3. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

4. Test whether there is improvement after updating the next system version.

WiFi is widely used in handheld devices, and smart phones are one of them. Different from Bluetooth technology used in mobile phones earlier, WiFi has a larger coverage and higher transmission rate, so WiFi mobile phones have become a fashion trend in the mobile communication industry. As the frequency band of WiFi is global free and does not need any telecom operation license, WLAN wireless devices provide a wireless air interface that can be used worldwide with extremely low cost and extremely high data bandwidth.

Users can browse the web quickly in the WiFi coverage area, and answer and make calls anytime and anywhere. And other broadband data applications based on WLAN, such as streaming media and online games, are worthy of users' expectation. With the function of WIFI, we can make long-distance calls (including international calls), browse the web, send and receive emails, download music and transmit digital photos. Don't worry about slow speed and high cost.

The full name of WiFi is wireless fidelity, also known as 802. 1 1b standard. Its biggest advantage is its fast transmission speed, which can reach 1 1Mbps. In addition, it has a long effective distance and is compatible with various existing 802. 1 1DSSS devices. With the notebook computer chipset proposed by Intel Corporation-"Centrino" being recognized by more and more people, this technology has gradually become a topic of concern.

However, since the end of 2005, many mobile phone manufacturers, especially brands that mainly produce smart phones, began to introduce WiFi into their products. Many mobile phones have built-in WiFi function, but the Ministry of Information Industry expressly stipulates that mobile phones with WiFi function are not allowed to be listed in China, so mobile phones listed in China do not have WiFi function.

Many of the same models can't use this function in China, but they can be used abroad. Traditional versions of mobile phones, such as dopod 586W and 577W, can use WiFi in China.

3. The phone is connected to WiFi, but the WiFi logo is not displayed at the top. What happened?

If the connection is not successful, the WIFI icon will not be displayed. If the WIFI connection has been successful, the icon can't be helped.

Normal display, maybe the system is abnormal. In general, if you have turned on WIFI and successfully connected to.

In this case, the notification bar of the mobile phone will display the WIFI icon.

It is recommended to try the following methods to solve the problem:

1. Switch the phone and wireless device again.

Dear users, it is recommended to enter Settings-General-Restore-Restore Network Settings. If the problem is not solved, it is recommended to restore all settings. If it still hasn't been solved, it is recommended to connect directly to the computer and download iTunes to restore it.

China Telecom provides the best network communication services, such as exchanging old friends for new ones, cashing old friends, free experience of 100 Mbps broadband, taking home ultra-clear TV iTV, and the activities of Telecom Day 5 17 can be directly inquired through the telecom online business hall or the entity business hall. The details are as follows: First, check whether the wireless router has turned on the power saving mode.

In the power saving mode, the transmitting power of the antenna will be greatly reduced, which will directly lead to the attenuation of wireless signals, thus affecting the wireless rate. Second, check whether there are obstacles between two wireless devices, especially metal objects.

Metal objects will seriously affect the transmission of wireless signals. Wireless devices can be placed in high places, and the signal coverage will be larger.

Third, check whether there are electromagnetic interference devices in the room, such as microwave ovens and cordless phones. If the wireless network frequencies of several devices are similar, it will interfere with the transmission of other wireless devices.

Most microwave ovens use the 7- 1 1 channel in the 2.4GHz band. So just change the transmission channel of the wireless router to 14Channel.

Fourth, router performance. The routing function of ADSL modem is limited. Generally, it is impossible for a device nominally connected to 5 clients to provide normal connections and services for 20 clients.

It is recommended to replace the broadband router with better performance. Fifth, the line quality.

ADSL requires high line quality. If the line is far away from the operator, there will be greater electromagnetic interference in the middle, which will have an impact on signal transmission. .
