How to remotely manage a Xiaomi router using your phone? When you're out, changing WiFi passwords or kicking unfamiliar devices can all be done in the Mijia app

Last month, I was working overtime at the company. My mom called to say that the internet at home was stuck and I couldn't watch the video, so I wanted to 'come back and fix it.' I took out my phone, opened the Mijia app, and glanced at the router's device list—my brother's gaming laptop was downloading games and was taking up 700 to 800 Mbps of bandwidth. I just set the speed limit, and after two minutes, my mom's video was smooth. I didn't leave my desk the whole time.

many people don't know that once a Xiaomi router is linked to the Mi Home app, people can manage their home router while away: checking who's connected, changing WiFi passwords, rebooting, or even disconnecting a device without having to go home, turn on the computer, or log in to 192.168.31.1. This article shares my experience with this remote management system, including the pitfalls I fell into, what I could do outside, and which things I had to do at home.

first bind the router to the Mi Home app: two binding methods

premise first: router must first connect to the internet , install the Mijia app on your phone, and log in to your Xiaomi account. If your home broadband is normal, binding usually takes about a minute.

the first binding method is the simplest. Connect your phone to the router's WiFi, open the Mi Home app, tap the plus sign in the top right corner, and it will automatically scan for nearby devices. The list will show "Xiaomi Router AX3000T" (showing your own model). Tap in and follow the prompts to bind. You may be asked to enter the router's management password to verify your identity.

can't find the first option, use the second: open the Mi Home app, tap the plus sign next to 'Manual Add', select 'Router' in the device category, then choose 'Router', then choose 'Xiaomi/Redmi', and scan the QR code on the back of the router body to bind it. This QR code is printed on the label at the bottom of the device, together with the SN code. Just scan it with your phone's camera. I used this method when I bought a Redmi AX6S on a second-hand platform. The previous owner unbound it but automatically found it wouldn't show up, so scanning the code was done in one go.

the binding is successful, the router's card will appear on the Mijia App homepage. Clicking it brings you to the management interface. Whether you're at home or using data outside, opening this card lets you see the real-time status of the router. this is the gateway remote management.

can't tie it up? Basically, these are the two situations

I succeeded on my first try binding myself, but I've helped friends and relatives tie a few cars. Summing up, there are two types of failures.

First type: The router is still tied to someone else's account. typical cases are second-hand purchased machines or elderly family members who previously linked their own accounts. This manifests as the final step of binding: "This device has been linked to another account." The solution is to have the original owner delete the device from his Mijia app; If you can't reach the original owner, just hold down the router's reset button for 10 seconds to restore the factory, reconfigure and connect to the internet, then bind your account. A factory reset will erase all settings, and you will need to reconfigure your broadband account password and WiFi name. Think carefully before you start.

Type 2: Firmware is too old and doesn't support Mijia. some older models around 2019 (I encountered an R4AC) come with the old Xiaomi router app system out of the factory, so you have to upgrade to the latest version before you can recognize Mijia. Log in to 192.168.31.1 in the web backend, check for upgrades in 'System Settings', and bind after upgrading. If your model is really too old and you can't find it on Mijia after upgrading, then it's completely unsupported and you can only manage it through the web backend— a reminder: it's best to check firmware updates manually, don't rely solely on automatic . I wrote an analysis router firmware auto-upgrade switch. You can check it out.

another uncommon situation: the phone is connected to the 5G band, while the router only has a 2.4G discovery channel enabled. This method involves switching your phone to the router's 2.4G WiFi and scanning again, which usually solves the problem of "automatic detection and scanning."

What can

people do outside: a few

, the functions I use most outside are these, sorted by usage frequency:

I want to talk about kicking unfamiliar equipment in this one. In the Mijia App's device list, each device has manufacturer information and names, so you can basically recognize it at a glance. If you find an unfamiliar device, just click in and select 'No Internet'—it's much faster than going home and running in the background. How to tell if someone is being moaned? I previously wrote an article WiFi a three-layer protection to prevent internet access. Remote kicking is just one part; changing passwords and disabling WPS also require follow-up.

the speed limit feature for devices is also very practical. Xiaomi's speed limit is set according to the device. On the device's details page, there's a speed limit switch, which limits uploads and downloads separately. My brother's gaming laptop is limited to 100Mbps; he still runs games and downloads, but it won't use up the whole family's bandwidth. As for the issue of children secretly playing on tablets after school, Xiaomi can set offline times based on the device, and it automatically disconnects at the right time—this approach is the same as guest network and time management. I've written about the general approach in the guest network and children's internet management , but Xiaomi makes it easier to operate in the app.

these operations can't be done remotely, don't waste your effort

remote management isn't a cure-all. I've tried a few things, and indeed, you have to be at home or use a web backend:

• Change the router management password (backend login password) : Mijia can only change the WiFi password; the management password must be changed in the 192.168.31.1 webpage backend. Fortunately, the password management supports mobile web operations, so you can do it at home using your mobile browser.
• broadband dial-up settings: changing internet access methods, entering broadband account passwords, and so on. Remote operation is too risky, so the app simply doesn't open it. I want to switch to using the backend for wiring at home.
• firmware upgrade : The new firmware push upgrade must be done on the router's local network; remotely, you can only check the current version number.

another reminder: when you change WiFi passwords remotely, all connected devices at home will be disconnected , including cameras and speakers. After changing, someone will have to re-enter the password at home. It was my first time changing my password remotely. My mom was at home at a loss when facing the smart speaker with the whole house offline, and she called me three times. Later, I learned my lesson and tried to do things like changing passwords when someone was home, or at least give me a heads-up.

Security as the String: Remote Management Is a Double-Edged Sword

features are great, but think about it: you can control your home router from anywhere, theoretically, anyone who gets your Xiaomi account can . Therefore, account security is more important than the router itself.

my approach is three things. First, enable two-step verification for your Xiaomi account. You can enable it in the Mi Home app settings. Once enabled, new devices will need an SMS verification code to log in. Second, don't use the default management password for the router; set it to two different sets from the WiFi password—how to set the management password and how to retrieve it if forgotten. I wrote an article about login to 192.168.31.1 in about this. Third, don't randomly add 'family' members in the Mijia app. Family members have default control over the device, so bringing in all the relatives is like copying the router key.

there's another detail worth knowing: Xiaomi routers have an old feature system related to "remote downloads," which runs through a different Xiaomi router app, but now mainstream models have all been integrated into the Mi Home. If you find an old tutorial asking you to install the "Xiaomi Router App" but find it can't log in or find the device after installation, don't suspect the device is broken—just replace it with the Mijia app. This is a historical legacy of app system upgrades.

There are two other things

App can do casually

Since the app is on your phone, I recommend opening two features that aren't related to remote management, but they're definitely worth it.

one is scheduled restart . The toolbox has a timed reset setting. I set it every Wednesday at 4 a.m., and if the router doesn't restart for a long time, memory usage keeps rising. Scheduled restarts can save you a lot of inexplicable lag. Where can you find this switch in the webpage backend? I've written about it in detail in Xiaomi router scheduled restart settings .

another is the of signal strength and heat generation. In summer, overheating of routers can also cause lag when everything looks normal remotely but experiences lag. I previously wrote about the entire process of handling heating and interruption in the Xiaomi Router Heating Troubleshooting . The simple method of raising ventilation and adding a small fan worked better than I thought.
