What's the matter with the mobile phone not going out?

First, close and restart the Wi-Fi connection.

When surfing the Internet with a mobile phone, a network IP address assigned by the Wi-Fi connection will be reserved in the mobile phone and applied to the current Wi-Fi. If there is no address conflict, don't worry. If there is a conflict, you must close and restart the Wi-Fi connection. The method is as follows:

Open the mobile phone menu, enter the settings bar, select wireless and network settings, enter the Wi-Fi settings item, select turn off Wi-Fi in a new window, turn it off and re-enter the item, and select turn on Wi-Fi to restart the Wi-Fi connection.

Second, ignore the network.

If this doesn't work, you should choose to let Android devices ignore the network and add it again.

Move out of 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 display, and then enter the network password to log in again. In this way, the Android phone should be able to get a new address and work normally.

Third, check the password of Wi-Fi.

Usually, the password of Wi-Fi should be changed regularly; However, when the network makes such adjustments, the mobile phone will not be updated automatically, and the password of Wi-Fi needs to be updated manually.

Move out of the coverage area of the problem network, enter the Wi-Fi configuration item to be adjusted, select "Adjust Network Settings", enter a new password in the window and view the entered password information, and finally select "Save Password". So Wi-Fi can work normally.

Fourth, check the advanced settings of Wi-Fi.

If the above methods can't solve the problem, the next thing to do is to enter the advanced settings of Android phone Wi-Fi and make relevant settings. Open the phone menu, enter the settings window, select wireless and network, enter Wi-Fi settings, then enter advanced options, enter proxy settings, and confirm that Android devices do not use proxy servers. If the IP address or domain name is found in the proxy section, delete it to solve the Wi-Fi connection failure.

Tip: In most cases, the proxy and port settings will not change; But there is nothing wrong with choosing to check these items when there are common problems with Wi-Fi.

Five, set the static IP address

Another solution is to set a static IP address for Android devices. This indicates that there may be a DHCP address assignment problem on the router to which the user needs to connect, or the device has obtained the wrong address. In order to set a static IP address, you need to enter the static IP address setting column and input information (IP address, gateway, subnet mask, DNS and other items).

The only problem with setting a static IP address is that it will apply to all Wi-Fi, so this method can only be used to solve the problem when the user is connected to only one Wi-Fi.

6. Turn off the Wi-Fi sleep strategy.

If Wi-Fi problems often occur, users should try to set the Wi-Fi sleep policy to never to see if the problems will disappear. If the policy is set to never, the power consumption will increase, but on the other hand, the Wi-Fi connection will be more stable.

Mobile phone is the name of Chinese mainland, and it is called mobile phone in Hong Kong, Macao and Taiwan.

1one day in April, 973, a man stood on the street of new york, took out a wireless phone about the size of two bricks and made a call, which attracted passers-by to stop and stare. This man is marty cooper, the inventor of mobile phone. At that time, Cooper was an engineer of the famous Motorola company in the United States.

The first mobile phone in the world was called to an opponent who worked in Bell Laboratories. The other party was also developing a mobile phone at that time, but it was not successful. Cooper later recalled: "I called him and said,' Joe, I'm talking to you on my mobile phone now. I heard the voice of "gnashing my teeth" on the other end of the phone-although he has always been quite polite. By April of 20 13, the mobile phone has been born for 40 years. The products of competition among scientific and technological personnel blossom everywhere, which brings great convenience to our modern life. Marty cooper is 74 years old. After working in Motorola for 29 years, he founded his own communication technology research company in Silicon Valley. He is the chairman and CEO of this company. Marty cooper's idea at that time was to let the media know that wireless communication, especially small mobile phones, was very valuable. In addition, he also hopes to attract the interest of the Federal Communications Commission. At Motorola and AT & amp； t(AT & amp； T is also a big communication company in the United States) supports the former. In fact, going back, we will find that the concept of mobile phone appeared as early as 1940s. At that time, the trial production was started by Bell Laboratories, the largest communication company in the United States. 1946, Bell Laboratories manufactured the first so-called mobile phone. But because of its large size, researchers can only put it on the shelf in the laboratory, and people will gradually forget it.
