Xiaomi router 192.168.31.1 I clicked through the background one by one, and found these 7 things that Mijia App couldn’t do.

On the day I returned home during the Mid-Autumn Festival, my mother complained that the WiFi at home was stuck at night. I took out my phone and looked through the toolbox in the Mijia App to change her channel. After searching for ten minutes, there was no such option. Finally, she opened her old computer and the browser clicked 192.168.31.1 , go to "Wireless Channel and Strength" under "Common Settings", and nail 2.4G from automatic to 6 in two minutes, and it will be stable that night.

I just realized that day. I have used two AX3000Ts at home for several years. I am familiar with the Mijia App, and I have never clicked through all the menus in the backend of the web page. While I had a computer at hand, I read 31.1 from beginning to end, and I completely understood "what things can only be done here."

First distinguish: Mijia App and 31.1 backend are not in charge of one layer of things.

Mijia App manages "daily glance"」: Who is online? You can check a strange device, change the WiFi password, open a guest network, and restart regularly. You can do it with just a few clicks. People can operate it remotely even from outside. Which parts of this part are useful and which are just decorations? I went through them one by one when I was writing a toolbox inventory. If you want to save trouble, just follow that list. .

But there is a prerequisite for the App path - it uses Mijia Cloud. Once the channel between the router and the cloud is disconnected, the App becomes blind. I am investigating this pitfall. The router shows offline in the App It was written very carefully in that article: The machine is obviously alive, but the App is spinning in circles because its eyes are in the cloud.

192.168.31.1 No, it's a local door. Connect your mobile phone or computer to the router's WiFi, and directly type 31.1 or miwifi.com Just go in, the data won’t go out, and you won’t look at the cloud’s face. The division of labor between the two sets of entrances can be explained clearly in one sentence: Use the app to change the WiFi name and password, and use the "network itself" settings to open the web page. . By the way, it is not absolute to open a computer. You can also access it through a mobile browser. Just filling in a long string of characters like a broadband account is still comfortable with a keyboard. In addition, Xiaomi also has a "Xiaomi WiFi" App. The toolbox is more comprehensive than the one at Mi's home. It uses the same machine's data as the web backend. I use it as an intermediate file.: It is more comprehensive than Mijia and more convenient than the web page, but it still cannot reach the advanced settings mentioned below.

Home screen: Status and device list, the fields are more comprehensive than those provided by the App

The first page after logging in is an overview of the status of the router.: Current connection method, WAN port IP, number of online devices, real-time uplink and downlink rates, plus a device list. Don't underestimate this list. Each device is followed by its own real-time rate. You can tell who is stealing traffic at a glance - my desktop computer was hung up with Steam updates in the middle of the night and consumed 92MB per second, which is on this page. Caught in action , which is much more than the list in the App that only tells you whether you are online or not.

I take a quick look at the WAN port IP line every time. The beginning of 100.64 indicates that the operator's large yard is in front of it. The beginning of 192.168 indicates that the optical modem is still in routing mode, and only the real public network address can connect to the device at home. I have written a complete version of this interpretation method , the troubleshooting of "why the remote connection cannot go home" basically relies on it.

Common settings: The first two pages must be entered on the day of installation.

「This column is filled with the most things. The firmware of my AX3000T includes Internet settings, WiFi settings, wireless channel and strength, LAN settings, and system settings from top to bottom.

Internet settings This is the main battlefield on the day of installation. Fill in the account and password for broadband dial-up here. You must report here after restoring the factory or replacing the modem. There are three advanced items hidden underneath it: One is DNS configuration, fill in the two boxes 223.5.5.5 and 119.29.29.29 That's it, I relied on it to save my old man's phone when the webpage couldn't be opened and ads popped up. ； The second is the IPv6 switch, which is a matter of ticking it. If you want to leave more remote paths for your NAS, just open it. ； The third is to switch the working mode. The three positions of router, wireless relay and wired relay AP are changed here. This is the way to change old routes to AP and feed smart devices. .

WiFi settings Manage name, password, dual frequency in one. The camera of the sweeper at home is not equipped with a network card. I turned off the dual-band in one. 2.4G and 5G each have their own names. The problems will be reduced by half immediately . The WiFi7 model has an additional MLO switch and it is also on this page. Do you want to open an article that I actually tested? , the conclusion is not arbitrary.

Wireless channel and strength Taking up a page by itself, it was the protagonist of that night at my mother’s house. The automatic channel jumped in the middle of the night, and the cameras and sweepers collectively lost contact. Manually pin 2.4G to one of 1, 6, and 11 , more stable than anything else. The three levels of signal strength are also adjusted here. The default level is enough. The gain of the wall-penetrating level is approximately equal to the error. I will calculate it based on the actual measured figures.

LAN settings Changing the LAN port IP and DHCP is only useful when fighting with the optical modem network segment or when connecting to the company's VPN and hitting the network segment. It cannot be touched twice a year. But that time I couldn't live without it . System settings (Some firmware versions are called system status) There are many reboots, manual uploads of firmware packages, Factory reset I also wrote a separate article about these life-saving operations, whether the firmware can be upgraded, and whether the automatic upgrade can be opened.

Advanced settings: The capital that the App cannot provide is all in this column

「"Advanced Settings" is the real cost of the web backend. The mapping list of port forwarding and UPnP is here - the one at home has 11 entries all year round, and the PS5 itself has 5 entries. For each entry, you can see which device applied for it and when. If you want to know who the router door is opened to, just look at this list . DDNS is also in this column. You can choose from four service providers: Peanut Shell, Public Cloud 3322, DynDNS, and No-IP. If you have a public IP and want to connect it to your home computer, Match it .

Scroll further in and there is IPTV. For families where Optical Mode has changed the bridge connection, the set-top box needs to re-identify the route. It depends on the IPTV switch hidden in the third-level menu in the advanced settings. The bridge mode is still a custom VLAN. Fill in the correct VLAN number to watch TV . QoS intelligent speed limit is also in this column. It is easier to protect the uploading of live broadcast equipment than to limit the speed one by one in the App.

These 7 things can’t be found even if the Mijia App is broken

After checking both sides, I put together a list of seven things in total that said "The app can't handle it and you have to go to 31.1".:

Strictly speaking, there is an eighth item: Manually upload the firmware package. It is in the system settings. The upgrade assistant in the App uses online upgrade. If you want to manually flash the specified version of the package, you can only open the web page. However, this life is not used once in three years, so it will not occupy a place inside and outside.

That night when the internet was disconnected, 31.1 was more reliable than the app

There is another scene worth remembering: If the broadband at home is cut off, the Mijia App will most likely follow the situation because it has to go around the cloud. At this time, the mobile phone is connected to the WiFi of the router (it can still be connected even if there is no network), and the browser clicks miwifi.com , the local backend can still be accessed—— This domain name is only resolved within the router's network , don’t look at the external network’s expression. Go to the homepage and take a look at the WAN port status, whether it is "Connecting" or "Authentication failed." You can tell at a glance whether it is a line issue or an account issue, and even the techniques for reporting repairs are different.

What you need to enter this door is the management password, which is the one you set when you initialized the router. It is two different things from the WiFi password. Xiaomi does not have a factory default password like admin. If you can’t remember it, don’t try it blindly. There is a right way to find it back .

Finally, I will give you the web backend route on the day of installation, five steps: Fill in the dial-up account in the Internet settings → Change the name and password in the WiFi settings, and turn off dual-band integration as needed → Pin 2.4G to 1, 6 or 11 in the wireless channel and strength → Confirm that the network segment does not compete with the optical modem in the LAN settings → Take a look at the UPnP mapping list in the advanced settings and you will have an idea. After completing these five steps, the remaining daily care can be left to the Mijia App. Both sides do their own work, and no one can replace the other.
