Mi 4 mobile phone can receive WiFi signal but can t connect, the password is also correct

The router is not set up correctly.

1.Turn on the power supply, then plug in the network cable, plug the incoming cable into the WAN port (usually the blue port), and then plug in any LAN port connected to the computer. After doing these jobs, you will see that there is an address and account password behind the router, and after connecting, enter the address you see on the router in the browser

2.Then enter, enter the corresponding account and password.

3.After entering the operation interface, you will see a setup wizard on the left, and the attack entry (usually pops up automatically).

4.Click Next, enter the Internet access method settings, you can see that there are three Internet access options, if it is dial-up, then use PPPoE. Dynamic IP can be used by plugging the computer directly into the network, and there is a DHCP server on the upper layer.

The static IP is generally a private line or something, or it may be a cell bandwidth, etc., and the upper layer does not have a DHCP server, or wants to fix the IP. As I dial up, I choose PPPoE.

5.If you choose PPPOE dial-up Internet access, you need to fill in the Internet account and password, which should be understood by everyone, and there will be an account number to open broadband, and it is OK to fill it in!!

6.Then the next step is to go to the wireless setup. You can see the channel, mode, security options, SSID, etc., generally SSID is a name, you can fill in at will, and then the mode mostly uses 11BGN

The wireless security option to choose WPA-PSK WPA2-PSK is so secure.

First see if your network environment is open, how to do it:

The computer should be connected to the Internet through routing;

If it is a router, there is no need to click on the broadband connection dial-up;

If you can't access the Internet, please check whether the routing settings are correct;

The wifi can be connected, which proves that the routed wifi is normal, it may be that the network is not connected, resulting in the inability to access the Internet!

Hope it helps

If you are satisfied, if you still have questions, you can continue to ask!

The general solution is, cancel the save first, enter the password again to connect to wifi, if the IP address is assigned, it means that the connection is normal, if the IP address is not assigned, the router is powered off and try, and finally it doesn't work to enter or reset the password in the router, and exit after saving.

Long press to select the wireless network, select the modify network, and then enter the password again, save, and that's it, I also encountered such a problem, and then it was solved.

I've also encountered this problem.,I've tried it for a long time.,I finally knew.,It's your input method problem,,Sogou and QQ Pinyin I tried it is not good,I haven't tried other input methods,Use the input method of the system to enter the password on the line。

Possible causes and solutions for Xiaomi mobile phones to enter the wifi password correctly, but they cannot connect to the wifi network:

First of all, check whether the wireless router is working normally, you can use other mobile phones or digital products to connect to the wifi signal, if you can connect and surf the Internet normally, then generally this router can work normally.

2.The phone is turned on to sleep and the network is turned off. Check whether the phone has the option to turn off the network in the dormant state, the phone will be disconnected after a period of time or cannot receive the background chat software, the possible reason is that the phone is turned on the function of turning off the network by mistake.

3.If you use the router for a long time, the router may freeze its death. Just restart your wireless router.

4.The type of certification is not suitable. Try to change the authentication type of the router, it is better to choose the secure "WPA2-PSK" type mode, and the following encryption algorithm is better to choose "AES".

5.The network settings of the mobile phone or router are abnormal. Consider restoring your router factory settings and cellular network settings.

You click and hold it to choose whether to save it, and then reconnect to try, if it doesn't work, go to the forum for help.

Please don't set a password when testing, try changing the SSID of the router. Be careful not to have too high a wireless channel.

I'm also doing this a lot, turning it off, turning it on, turning it off, and trying it many times before I got connected.

After deleting the network, enter the password again.

Just turn off the network, turn it back on, and you're good to go.

You turn your phone off and on again.

1. First of all, make sure that the 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 almighty fix first - 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 connection devices - too many digital devices connected to the wifi of a wireless router is very stressful 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.

Hello. You can set up your phone by following the steps below:

1.Click Settings --Wi-lan, select the arrow next to the name of the network you want to connect to, select Don't save the network, and re-enter the password.

2.Restart your phone and router.

3.Still doesn't work, I recommend you try other wifi networks to see if it works.

If it can be used normally in other WiFi router environments, then it may be caused by the current problem of this router itself.

Xiaomi phone flashing tutorial:

The first reason: the password is wrong, please double-check that the password is entered correctly. Unless the restriction is lifted, your mobile device will not be able to connect to the wifi network signal normally.

Method 1:

Settings - General - WLAN - Turn off the WLAN function, turn it off and then turn it back on and then reconnect to the WiFi.

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 the above methods to try to solve.

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.
