The password for Xiaomi router is clearly correct but I can’t log in? 192.168.31.1 I have dealt with all five situations in which password errors were reported.

Last month, my mother-in-law called and said that the computer could not be accessed. 192.168.31.1 , the page keeps popping up "Wrong password". She swore on the other end of the phone that the password was posted on the notebook next to the router and she remembered every word correctly. I coached remotely for forty minutes, and finally found that she used the WiFi password to fill in the management password box - the two passwords were written next to each other in her notebook, and the old lady read the serial.

After this incident, I paid close attention to it, and encountered similar situations with colleagues and neighbors one after another, and collected five real cases where "the password was clearly correct but the error was reported." Write it down clearly today, so that you don’t have to do what I did before and almost press the reset button to clear the whole family configuration.

First distinguish the two passwords: Nine times out of ten when you get an error, you got the wrong key.

Xiaomi router has two completely independent passwords: WiFi password It was lost when the mobile phone and computer were connected to the wireless network. Admin password It's the browser knocking 192.168.31.1 Then the box that pops up asks for it. The two passwords can happen to be the same, or they can be completely different. The system doesn't care, but you do.

Why are these two passwords the easiest to mix up? Because there is a checkbox on the wizard page for setting up the router that says "Same as WiFi password." When I installed the computer, I slid my hand to hook it up, and the two passwords were tied together. ； Later, my family changed the WiFi password, and the management password was also changed, but the old password was still recorded in the notebook. When I want to go into the background and change the speed limit one day, I will enter "wrong password" - the one in the code book was indeed correct, but it has been retired.

There is a way to verify on the spot: If the phone is still connected to WiFi, go to the router device page in the Mijia App. If you can get in, it means that the bound channel is still alive. At this time, use the "WiFi Settings" in the App to take a look at the current WiFi password, and then use this password to try the background box. For families that have checked "Same", the two passwords are tied together, and one is correct for the other. This path for unchecked families is in vain, but at least one possibility is eliminated. How to check the WiFi password in the App, I have written a detailed article, here How to check if Xiaomi router WiFi password is forgotten , both Android and Apple mobile phones are available.

Your browser is doing you a disservice: Autofill fills in the old password

The second most common situation is more subtle, and I have fallen victim to it myself in my company. The browser is very considerate. When you see the password box, it asks you if you want to save it, and you save it. Later, the router changed the password once, but the browser still remembered the old version - every time you clicked to log in, it automatically filled in the password from three years ago, and the page reported "wrong password", and you were still wondering.: I obviously entered nothing wrong.

Typical features of this situation are: If you manually type word by word, you will be able to enter ； Click autofill and an error will be reported . On the other hand, if you have been clicking auto-fill to enter the background, but one day you suddenly can't enter, don't doubt the router first. Most likely, the password on the router has changed, and the browser doesn't know it.

It only takes a minute to verify: Clear the password box, click and hold the mouse to select and delete them all. Do not use the backspace key to delete them one by one (some password boxes will leave an invisible tail character if they are not deleted completely). Then enter it manually. The same applies to mobile phones. Don't click on the "Autofill suggestions" on the input method. Type it yourself. If you find it troublesome, just open the browser in incognito mode to access it. 192.168.31.1 , the incognito mode does not have a saved password, forcing you to enter it manually, and you can try it out one time to find out whether it is true or false.

By the way, I later developed the habit of saving a separate password record for the router backend, recording and naming it separately from the WiFi password (such as "Router-Enter" and "Router-Connect") to prevent the browser from confusing them as passwords for the same site. The general idea of ​​​​managing passwords, I am Connect the old device after changing the router It was also mentioned in that article: It is better to manage several sets of passwords at home separately than to mix them all together.

Input method problem: Full-width characters and invisible spaces

The third situation is the least common, but can drive people crazy if it happens to them. The letters and numbers typed out by the Chinese input method in the "full-width" state are exactly the same as the half-width ones, slightly wider and almost indistinguishable to the naked eye, but to the router they are completely different characters. You are right when you see the password with your eyes, but what the machine reads is another password.

The time I encountered it was an old laptop. I don’t know who cut the input method to full-width (shortcut key Shift + Space cuts when touched). There was a letter a in the password. If I typed it in full-width mode, the router would not recognize it. Later, when I showed the password and looked at it, I realized that the a had gained weight. The Xiaomi router login box of the National Bank does not have a "display password" little eye, which is a trap - you can't even see what you entered.

The solution is very simple, just remember two actions: before input Press Shift+Space to switch back to half-width , or simply switch to English input method and type again. Don’t rush to enter after typing. Take a look at the status bar of the input method. The moon icon is half-width, and the round sun is full-width. In addition, the leading and trailing spaces are also pitfalls of the same kind.: On some keyboards, the space next to the Enter key is easy to touch accidentally, and there is an extra space at the end of the password, which is completely invisible on the screen. Therefore, when entering the password manually, pause for half a second after typing the last character, confirm that there are no more keys, and then submit.

Continuous input errors result in temporary lockout: The more anxious you are, the harder it is to get in.

The fourth is the router's self-protection. If you enter the wrong password too many times in a row, the background will temporarily refuse to log in. Even if you finally remember the correct password, it will be in vain and the page will still report an error, or simply prompt you to wait. This was the process for my mother-in-law's time: I tried three times with the WiFi password, and then twice with the old management password on the notebook. After five attempts, the protection was triggered. I asked her to use the correct password on the phone, but she couldn't get in. I thought the router was broken and needed to be repaired.

This mechanism is available in all routers, and the specific locking time varies. Xiaomi's home models generally have a short cooldown of tens of seconds to a few minutes, unlike bank apps that often lock for half an hour, but you can't stand it and you don't know about it - during the cooldown period, the more you try, the more mistakes you make, and the more mistakes you make, the longer the cooldown becomes, a vicious cycle.

Here’s what to do if you encounter a suspected lockout: Stop, make a cup of tea, and lose only once in ten minutes . In these ten minutes, go through the contents of the first three sections.: Make sure you are getting the management password and not the WiFi password. If you are going to enter it manually, do not turn on autofill and use the half-width input method. If you lose right once, go straight in. If you still get the error after typing it manually after ten minutes, then it’s really not a locking problem. Let’s move on to the fifth case.

It's really not that you remembered it wrong: The password was changed on the router.

The last one is that the password did change, but it was not changed by you. two sources: One is that someone in the family has changed it - your child wants to change the WiFi name, or a family member has changed the settings in the Mijia App and changed the management password when changing it, and no one remembers to notify you. There is no function of "whoever changes the password will broadcast it" when it comes to the router password. It all depends on self-consciousness, and self-consciousness is never reliable at home.

Another source is reset. The router was restored to the factory by mistake (a naughty child poked the Reset hole with a card pin, or a bump triggered a long press when moving). When you re-enter the guide, a new management password will be forced to be set. Who set it and what was set, God knows. There is a simple way to determine whether the router has been reset.: If the WiFi name becomes Xiaomi_An unfamiliar name with a string of letters and numbers at the beginning has probably been reset in 80% of cases. ； The WiFi name has not changed, so the probability of being reset is low.

At this point, the password is really impossible to retrieve, so don't try again - every time you enter the wrong password again, you are adding fuel to the locking mechanism. two right paths: Those who have been tied to Mijia can use the toolbox in the App to bypass the web page password and directly manage it, and those who have not been tied to Mijia can use the password retrieval process. How to take these two roads and what prerequisites are required for each. I have been through a complete pitfall before, and I wrote it in What should I do if I forget my Xiaomi router background password? In that article, the wild way to configure telnet is also included, which is useful for saving lives. It is really hopeless. Reset and redirect the guide is the last resort. The price list is Factory reset I’ve listed it in that article, so start after reading it.

A prerequisite for self-examination: Are you logging in to your own router?

After talking about the above five types, there is still a low-level but real premise question that needs to be clicked on.: Is the WiFi you are connecting to your home? If the neighbor in the building also has a Xiaomi router, and the WiFi name is the default style left by the installation master (Xiaomi's house, Lao Wang's house next door, the names all look familiar), if the phone automatically connects to the neighbor's network, you type it in the browser 192.168.31.1 What was entered was someone else's router - the password was of course "wrong", and what was locked was someone else's account.

Verification method: Go to the mobile WiFi details page to see the gateway address. The gateway is 192.168.31.1 Only then can I connect my own machine correctly. ； A more stable way is to check the WiFi name, and then operate if it matches the sticker on the bottom of the router or the name written in your notebook. Routing layer problems such as connecting to the wrong network, typing the wrong address, and relay mode management IP drift, which are "not password problems at all," were previously reported in 192.168.31.1 Can't open, can't get in The complete troubleshooting chain is written in that article. If the password box pops up, please refer to this article. If the password box does not pop up at all, please refer to that article. The two articles are just connected.

ending: Follow the set sequence and reset when you don’t get up to speed.

Compress the five situations into a table. Next time you encounter "the password is obviously correct", go through it in this order, and you can basically locate it in ten minutes.:

There is no need to change any configuration in the first five steps in the table and there is zero risk. Complete it first and then consider the sixth step. The mother-in-law followed this order that time, and the second step was successful - what she saved was a reset and the effort of reconfiguring the network for more than a dozen devices in the whole family. Before finishing, let me say a few words about daily habits.: Set the management password to a combination that is different from the WiFi password and is known to everyone in the family but unfamiliar to outsiders. Write it in two lines in a notebook with a horizontal line in the middle. These days, even routers are starting to talk about "password separation", and your password book should follow suit.
