Xiaomi Mi 4 can t get on the Internet after turning off wifi, why

If the root uses the router's "lazy mode one-click setting" to configure the router's Internet access parameters, and if "Automatic" is selected by default in the encryption authentication method, there may be a problem that the mobile phone can connect to WiFi but cannot access the Internet.

The Wi-Fi encryption authentication type is set to Automatic by default, which causes the problem.

The Wi-Fi encryption authentication type is set to Automatic by default, which causes the problem.

Solution: Since we know that the wifi encryption type is selected as "automatic" by default, the solution is also very simple, just manually select the wifi encryption type as the most secure and reliable "wpa2-psk". After restarting the router, all devices will be able to surf the Internet normally.

Hello. Can't get on the Internet" This question is very general, I try to guess the problem you may encounter, I suggest you try the method to operate it and see:

1. It is recommended that you put this SIM card into another mobile phone to check whether you can access the Internet.

2. If you can't access the Internet, please ask your carrier if you are in arrears.

3If it can be used, please put it in your Xiaomi phone, turn on the data switch, and reset the default in Settings - Access Point APN, and then restart the phone to try again.

4If you still can't access the Internet, it is recommended that you back up your data, enter recovery to clear all data (turn off, press and hold the volume up + power button to enter recovery), upgrade your phone to the latest development version of the system, don't install apps that require root permission for the time being, and see if it can be restored to normal.

At the same time, 9 Xiaomi Home in Beijing, Shanghai, Nanjing, Wuhan, Chengdu, Hangzhou, Xi'an, Shenzhen and Guangzhou have maintenance capabilities. Mi Home is open from Tuesday to Sunday, from 10 a.m. to 6 p.m.

Philosophy: Why do you have such a retarded mind?

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.
