What is in the background of Xiaomi router 192.168.31.1? I ordered the menu one by one, and these seven things really can't be handled by the Mijia app

the day I came home for Mid-Autumn Festival, my mom complained that the WiFi at home would lag every night. I took out my phone and searched through the toolbox in the Mi Home app, hoping to change her channel. After ten minutes, there was no option at all. Finally, I turned on her old computer, typed 192.168.31.1 in the browser, went to 'Wireless Channels and Strength' under 'Frequently Used Settings', and in two minutes set the 2.4G from auto to 6. That night, it was stable.

day, I realized that two devices at home AX3000T had been used for years. I was very familiar with the Mijia app, and I hadn't even managed to click on all the menu in the backend webpage myself. Taking advantage of having a computer on hand, I flipped through 31.1 from start to finish and thoroughly figured out what "can only be done here."

clarify: the Mi Home app and the 31.1 backend are not managed by the same thing

Mijia App manages "daily glances": who's online, kicking an unfamiliar device, changing WiFi passwords, opening guest networks, scheduled restarts—just a tap of your finger and remote operation even when you're away. Which parts are useful and which are just decorations? When I used to write toolbox inventory, I went through them one by one. want to make things easier, just follow that list. .

But the app path has a prerequisite—it goes through Mijia Cloud. Once the router's connection to the cloud is cut off, the app becomes blind. I'm investigating this pitfall the router shows offline in the app and the article explains it in detail: the machine is clearly alive, but the app just spins because its eyes are in the cloud.

192.168.31.1 is different; it is a local gate. Connect your phone or computer to the router's WiFi, just type 31.1 or miwifi.com in your browser and you'll get in. Data doesn't go out, and you don't have to worry about the cloud's attitude. The division of labor between the two entry points can be summed up in one sentence: small things like WiFi name and password, use the app, and set up the "network itself" to open the web . By the way, having a computer isn't absolute; you can access a mobile browser, but just filling in those long strings of broadband characters is more comfortable with a keyboard. Xiaomi also has a "Xiaomi WiFi" app, which has a toolbox that is more complete than the one in Mijia. The web backend uses data from the same machine. I use it as a middle ground: Bimijia is more convenient than the webpage, but it still can't access the advanced settings I'll discuss below.

Home screen: Status and device list, fields compared to the full

the first page after logging in, you'll see the router's status: current connection method, WAN port IP, number of online devices, real-time upload and download speeds, plus a list of devices. Don't underestimate this list—each device follows its own real-time speed, and who's stealing data can be spotted at a glance—my desktop is running Steam updates at midnight and eating up 92MB per second. The current caught this page is way more than the list in the app that only tells you if you're online.

WAN IP trades. Starting with 100.64 means the operator is pressing down on the big yard ahead; 192.168 means the optical modem is still in routing mode, and only a genuine public network address can connect to your home device. I've written a full version of this method, and checking "why remote connections can't go home" basically depends on it.

Common settings: On the day of installation, the first two pages must be accessed

"Frequently Used Settings" section is packed with the most items. On my AX3000T, the firmware section from top to bottom consists of internet settings, WiFi settings, wireless channel and strength, LAN settings, and system settings.

internet settings the main battleground on the day of installation. Enter your broadband dial-up account and password here. After factory reset or switching to a modem, you will definitely be called in. Underneath it are three advanced features: first, DNS configuration—just enter 223.5.5.5 and 119.29.29.29 in the two boxes, and that's it. the senior phone webpage wouldn't open and ads popped up, I relied on it to save ; Second, the IPv6 switch—just check it. want to leave an extra remote route for the NAS, just turn it on ; Third, switching operating modes: router, wireless relay, and wired relay AP switch. old router switched to AP feeding, this is the for smart devices.

WiFi Set tube name, password, and dual-frequency integration. The vacuum cleaner's camera at home is stuck in the network. Turn off this dual-band integration, and the 2.4G and 5G models each have their own names, instantly reducing issues by half . WiFi 7 models also have an added MLO switch on this page. should you turn it on? I tested it in one , and the conclusion is not to use it blindly.

wireless channel and strength take up a separate page, and it was the star of that night at my mom's house. The automatic channel skips at midnight, cameras and vacuum cleaners all lose contact, manually pins a 2.4G in 1, 6, and 11, which is more reliable than anything else. Signal strength level 3 is also adjusted here; the default level is sufficient. The wall transmission mode yields about the margin of error. I calculated the actual numbers.

local area network settings change LAN port IPs and DHCP to only use them when conflicting with optical modem segments or connecting company VPNs to overlap segments. You can only encounter them twice a year, if you do have one, you really can't do without it. system settings (some firmware versions are called system status), I have written a separate article about these life-saving operations—rebooting, manually uploading firmware packages, factory reboot whether firmware upgrades or automatic upgrades happen.

Advanced Settings: All the capital the app can't provide is in this section

"Advanced Settings" are the real asset of the webpage backend. Here is the map list for port forwarding and UPnP—my phone has 11 lines on the clock, and the PS5 has 5 on its own. Each one shows which device applied for it when. want to know who the router door is for whom, just look at this list . DDNS is also in this section. Peanut Shell, Gongyun 3322, DynDNS, and No-IP providers are all you like. If you have a public IP and want to connect to your home computer, use it .

further inside, there's also IPTV. The optical modem switched to a bridging home, and the set-top box had to re-identify the way. This relied on the IPTV switch hidden in the third-level menu in advanced settings. The bridge mode was still customizable VLAN, and you enter the correct VLAN number to watch the TV . QoS smart speed limiting is also in this section, so you can guarantee uploads for your live streaming devices, which is much easier than setting speed limits one by one in the app.

these 7 things, no matter how much you mess through the Mi Home app, you still can't

checking both sides, I put together the "app can't be applied, must enter 31.1" into a table—seven items in total:

strictly speaking, there is an eighth item: manually uploading firmware packages. In system settings, the upgrade assistant in the app supports online upgrades. If you want to manually flash a specific version of the package, you can only open a webpage. But since it doesn't need to be used even once in three years, it won't be given any more space.

the night the internet went off, 31.1 was more reliable than the app

there's another scenario worth remembering: when your home broadband goes down, the Mijia app will probably spin in circles because it needs to loop through the cloud. At this point, the phone is connected to the router's WiFi (even without internet), and the browser miwifi.com accessible, the local backend can still be accessed as usual— this domain only resolves within the router's network, regardless of the external network's attitude. A quick look at the WAN port status on the homepage shows whether it's "connecting" or "authentication failed." You can immediately tell whether it's a line issue or an account issue, and even the repair request wording is different.

to enter this door, you need the admin password, which is the one you set when initializing the router. It's a completely different thing from the WiFi password. Xiaomi doesn't have the default admin password at all. If you can't remember it, don't try blindly— you can get it back the right way.

wrapping up, here's the webpage backend route for the day of installation. Five steps: enter the dial-up account in Internet settings→ Change your name and password in WiFi settings, and turn off dual-band integration as needed. → In wireless channels and strength, set 2.4G to 1, 6, or 11→ In LAN settings, confirm the network segment doesn't conflict with the optical modem. → In advanced settings, check the UPnP mapping list to be sure you have a good idea. After completing these five steps, the remaining daily care can be handled by the Mijia App. Both sides do their own work, and neither can replace the other.
