Xiaomi Mi 4 is connected to wifi and the network has not worked, what s going on

How to set up problems in the wifi connection:

Method 1: Settings - General - Wi-Fi - Disable the Wi-Fi function, turn it off and then turn it back on and then reconnect to Wi-Fi.

Connect to wifi with a mobile phone, after the initial successful connection, the mobile phone will retain a network IP address assigned by the wifi connection, it will be applied to the current wifi, if there is no address conflict, then you should be able to surf the Internet normally, but if there is an IP conflict, you can use this method.

Method 2: Settings - General - WLAN - Select the wifi with abnormal connection - click the wifi signal icon on the right - click Cancel Save - then re-enter the password and reconnect, so that the operator can get a new address and connect normally.

Method 3: If the connection to WiFi stays in the verification stage and cannot connect normally, you need to check whether the WiFi password is entered correctly, whether the WiFi password has been changed, or whether the security rules of the router are set correctly.

After the wifi password is changed, the mobile phone cannot be connected, and the wifi password needs to be manually updated. If the wifi password is entered incorrectly, you also need to manually re-enter the wifi password. You can refer to the second trick:

Settings - General - WLAN - Select the wifi with abnormal connection - click the wifi signal icon on the right - click cancel save - then re-enter the password and reconnect, so that the operator can get a new address and connect normally. Re-enter the correct password and reconnect to the Wi-Fi again.

Method 4: Settings - General - WLAN - Select the wifi with abnormal connection and long press - Select Modify Network - Show advanced selection, view and change ** and IP settings according to router security rules. In most cases, ** and port settings won't be changed, but when there are common problems with WiFi, you can't go wrong with choosing to view these items.

Method 5: On the basis of the fourth trick, if the default settings cannot connect normally, you need to consider or check whether there may be a DHCP address allocation problem on the connected router or the device has obtained the wrong IP address.

You can find the following settings: Settings - General - WLAN - Select the wifi with abnormal connection and press and hold - select Modify Network - Show advanced options - Change the IP settings to static, and then enter the relevant parameters according to the route settings. It should be noted that setting a static IP address may not be applicable to all routers, if you switch to a different WiFi environment and cannot access the Internet normally, you may need to restore the default settings or make appropriate modifications according to the router settings in the current WiFi environment.

Method 6: In addition to trying to solve the problem with the above methods, you can also see if there is a problem with the router or broadband.

1.Check whether the connection between the network cable and the router is normal;

2.To check whether the broadband is working, you can contact the network provider, such as 10000 of Telecom

There are several scenarios in which the phone cannot connect to Wi-Fi properly:

2) If the router is faulty, try to restart the router.

2. Prompt that the connection to the wifi is refused, and the fault phenomenon: others can be connected, but they can't connect to the wifi, and the connection is refused. Here's how to fix it:

2) If the router is faulty, try to restart the router.

3. The mobile phone connection to wifi prompts that it has been saved, but the connection fails. Here's how to fix it:

1) This prompt indicates that the encryption method, password or signal channel of the router of the wifi signal has been modified. It is recommended to reset the password and encryption type of the router, and the terminal connected to this network needs to [Ignore this network], and re-enter the password to connect.

2) If the router is faulty, try to restart the router.

1. Mobile phone wifi setting error: If this situation occurs, the wifi will show that the wifi has been successfully connected, or it is being connected, but there is always no wifi.

Solution: Delete the original wifi, then click on the wifi and re-enter the password.

Solution: Factory reset or flash the phone system to a lower version, which can effectively solve this situation.

3. Too much self-starting software: too much self-starting software will affect the running speed of the mobile phone, and it will also affect the connection of wifi.

1. First of all, make sure that your router is not working normally, you can use other mobile phones or digital products to connect to the wifi hotspot, if you can connect and surf the Internet normally, then generally speaking, this wireless router can work normally.

2. Secondly, make sure that the mobile phone with a problem with the wifi connection does not have the option to turn off the network in the sleep state, and there are many children's shoes that their mobile phones will be disconnected after a period of time or can not receive the information of the background chat software, most of them are because they inadvertently or mistakenly turn on the option of turning off the network from the mobile phone.

3. Wireless router problem:

1) Dead cycle - many wireless routers sometimes have a connection into a dead loop, that is, they keep getting IP and connecting, but they can't connect to wifi hotspots. - Let's try the all-purpose fix - restart. After turning off the power of the wireless router completely, turn it back on again after about 10 minutes.

2) Whether there are too many WiFi connected devices - too many digital devices connected to the wifi of a wireless router will put a lot of pressure on the wireless router, and it is easy to cause IP conflicts and cannot be connected - such a problem can be solved by setting a static IP for each device connected through WiFi.
