What's in the Mijia App router toolbox? I went through a dozen tools one by one; out of five, I used them and three were just decorations

my home router is AX3000T, and in the first year after installing the Mijia app, I had no idea there was a 'toolbox.' Until one night, I found the network was scratched and searched through the app before finding this row of tools in the corner of the router's device page. Later, I clicked through all the dozen or so features in the app one by one. I use five of them every day, and three I just open them once and never touch them again. This article will clearly organize this row of tools, so you don't have to wait until you have trouble like me to look for them.

clarify first: where is the toolbox, and why can't you find it

entry path is simple: Mijia App →, tap the device card on your router →, scroll down the middle of the screen, and you'll see a row called 'Toolbox.' Tap it to see all tools. The old interface was called "Recommendation Tool," and the location was similar.

There are generally three situations where

can't be flipped. First, your router is an older model (AC series, R3 batch), and many features in the Mi Home app have been cut. You need to install the standalone "Xiaomi WiFi" app, which has a more complete toolbox, including photo album backups and red packet WiFi. Both apps run on the same machine, so changes to either side take effect, and the data is connected. I keep two on my phone: I use the Mi Home app a lot because it shares the same roof as the speaker and camera; Only enable Xiaomi WiFi if you really want to check niche features. The second is that the firmware is too old. The tools follow the firmware version, so upgrade the firmware first. I've written about the full process of manually upgrading Xiaomi router firmware . The third and most unfortunate scenario is when you open it under mobile data. Some tools only turn on when your phone is connected to the router's WiFi, so you have to switch back to WiFi and then log in.

there's another misconception to correct first: the items in the toolbox are divided into two types—one is a switch that actually works, and the other is an entry shortcut—clicking it only takes you to the router's settings page. Don't treat the latter as a new feature.

three I use every day, each one has saved me in emergencies

first is anti-scrape netting. this switch is turned on, if an unfamiliar device connects to your home WiFi, your phone will immediately pop up a notification, including the device name, MAC address, and connection time. That's how I caught my phone that was trying to ride the internet. Later, I followed the process and found the full process, which I wrote about in the of Xiaomi router checking for internet access. The toolbox also allows you to directly blacklist and whitelist users, and even if the blocked device is restarted, the router cannot be restarted.

second is the WiFi Treasure Chest. has a signal detection option. Click it to check the signal strength at every location in your home. The number is negative, so you can use it anywhere below -50, but below -70, it should lag. When I checked mesh roaming stickiness, I relied entirely on it to prove it: the phone showed full bars but was lagging. Upon checking the toolbox, it stuck to the -74 sub-router and wouldn't move. This process is detailed in the of the Mesh roaming without switching sections. Before buying a signal amplifier, test it around and save a lot of unnecessary money.

third is remote reboot. was at the office, and a call came from home saying the network was down. I took out my phone and tapped 'Restart the router'—just wait a minute or two. This feature looks insignificant, and once you use it, you can't go back—before, I could only call my mom to help her unplug the power supply, and she could always unplug the fiber modem cable. By the way, remote restart is a quick fix. If you find that the router needs to restart every few days for smoothness, that's an overload or firmware issue. You have to address the root cause. The more hassle-free method than manual scheduled restarts is something I wrote in about scheduled restarts. I set it to 4 a.m. every Wednesday, and I haven't gotten up in the middle of the night for half a year.

if your family has kids and guests, open these two

Children's internet control: set internet time slots for children's devices, with disconnection at 10 PM and game video categories and blocking. The toolbox entry and the 31.1 backend share the same set of data; the app side wins by allowing remote changes—even during business trips, you can make up for forgotten controls. A complete setup approach, including how to prevent children from using secondary data cards to bypass them, which I wrote in the article on children's internet control .

Guest WiFi: guests open a temporary network isolated from the main network, so guests can't access your NAS or access the router's backend. The day the broadband installer asked for my password, I had this one opened. After using it, I just turned it off without changing the mainnet password. The entrance is called 'Guest WiFi' in the toolbox. I've tested the exact boundary once, and the Guest Network has a complete record.

by the way, the entry point for QoS speed limiting is also near the toolbox (some firmware is in "More Settings"). Limiting the upload and downlink of live streaming devices is more effective than arguing. The numeric reference table is in the Xiaomi router speed limiting article.

look beautiful but are actually useless three

Game Acceleration: you only find the accelerator membership portal when you enter, and you need to buy the service separately for it to be meaningful. If the home bandwidth itself has stable latency, you won't feel anything when you turn it on; When it comes to real cards, what you should check is the NAT type and channel, not the membership purchase.

Internet Report: send you a weekly report showing who has been online for how long and how much data they have used. The first time I saw it, it was quite novel, but I never clicked again the second time. If you really want to manage devices and access the internet, managing children is much more direct.

Album Backup: outdated feature, you need the router to be plugged into a USB hard drive to work. The functionality itself is fine, but I recommend backing up phone photos directly to the NAS, with automatic upload unrestricted by router storage restrictions. The comparison between the two options is in the article about phone photo backup to NAS. If you don't have a NAS, you can just plug in an old USB drive as a lightweight shared drive. I've written about USB interface usage before.

two common pitfalls—know them before you act

pitfall one: Smooth connection is enabled by default. Toolbox → WiFi settings has a "Smooth Connection" option, which is enabled by default out of the factory to help you automatically connect to the best signal bands. It sounds good, but old cameras and printers at home often have compatibility issues—the device is directed to unsupported bands, causing repeated offline disconnections. The troubleshooting method is simple: separate the dual-band and fix 2.4G on IoT devices. The idea is about separating 2.4G and 5G.

Pitfall 2: Not finding a certain function in the toolbox—it's not your imagination. different models and firmware versions, the toolbox contents differ; the official manual itself states "varies by model." Have you searched everywhere? First, upgrade the firmware; After the upgrade, it's still not available. If you don't have this machine, don't push it to the limit. For example, for a factory reset, some firmware apps don't have it, so you have to go to the 31.1 backend or reset the pin to the pin. Both methods are the factory reset article has been covered.

here's a fun fact: the "Device Management" section in the toolbox and the device list on the homepage are two doors of the same item, but the toolbox entry now has an "View Historical Devices" section—even offline devices are recorded. Whether my robot vacuum really disconnected or what time it went off depends on checking the timing here. It's especially useful when Mijia devices repeatedly go offline. The complete troubleshooting sequence is in the article Mijia devices going offline.

Conclusion: Which App to Use and Which to Use 31.1 Backend

used it for over a month, and my division of labor was as follows: daily checking status, free-roaching, remote restart, temporarily changing WiFi passwords, using the app because it lies on the phone, fast; Dynamic structure—change LAN subsidiary, change internet method, firmware upgrade, dual-band split, go to the 192.168.31.1 web backend because many advanced settings on the app side don't even have an entry point. It's also recommended to set a scheduled restart in the background once and then forget about it. How to choose the frequency depends on about scheduled restarts.

In the end,

comes down to one thing: first turn on anti-anti-anti-internet notifications—that's a free sense of security; Then use the WiFi gadget box to check the home signal so you know where the weak points are; The rest are available on demand. The toolbox has quite a few items, but the ones you actually know how to use are probably only three or five of them.
