How to change the WiFi password on a Tenda router on a mobile phone? There were two routes: the app and the tendawifi.com. I switched to my mother-in-law's house in 10 minutes

Last month, my mother-in-law's house wifi got hacked by the neighbor, and my phone data ran out by the end of the month. I asked myself to go check it out over the weekend. Her router was a Tenda AC10 installed by the technician when she got broadband two years ago. We don't have a computer at home, so I brought my phone and changed the password in ten minutes. This article notes both paths: one app and one web backend, so you can choose whichever suits you. My home uses a Mercury machine. I've previously written about changing the WiFi password on a Mercury router phone, and the process is pretty similar, but the interface is different.

clarify first: the WiFi password is changed, not the background login password

many people get stuck at the first step, confusing these two. The WiFi password is the one the phone inputs when connecting to Wi-Fi; The backend login password is required when accessing the management page. The older Tengda models come by default by admin, while many new models come out empty. This article changes the former.

By the way, if you forget your backend login password and can't access the admin, that's a different issue. I've written about Tenda's initial password rules, which are completely different between old and new models. You can check Tenda router's initial password. Don't panic if you forget your WiFi password. As long as your phone is connected to the router, you can change it while you're nearby, so you don't need to know the old password.

Route 1: Change Tengda Router App to link once and then manage your phone anytime

the app store, search for "Tenda Router"; the icon is an orange T-shape. The advantage of this route is that once you bind it, you can remotely change passwords and kick unfamiliar devices even when you're away, without needing your phone to connect to home WiFi—my mother-in-law later learned to check the device list by herself, faster than I thought.

steps for the first binding:

• connect your phone to Tenda's WiFi (don't touch the old phone you need), open the app
• and it will automatically detect the Tenda router in the current network. Click "Bind Now"
• prompt to set a management password, set an 8-character plus number or more. Don't mess with admin
• Home page click " WiFi Settings' will be displayed below the WiFi name in the password box. Change it to a new
• to save, the phone will automatically reconnect, and other devices will enter the new password one by one

there's a small variable to watch out for: my mother-in-law's AC10 has an old firmware, and the app homepage shows the WiFi name and password box directly; Later, when I was working on my own AX12 PRO, the password change portal was moved into the "Toolbox," and I spent over a minute searching for it the first time. The menu location shifts depending on the app version; just look for the words "WiFi Settings" and you'll find it by scanning twice.

Method 2: Open the tendawifi.com in your mobile browser, so you can change your

don't want to install apps, just use a browser. After connecting your phone to WiFi, enter tendawifi.com in the address bar (note: it's the address bar, not the search box), and it will automatically redirect to the router's management page. Directly entering 192.168.0.1 yields the same effect. This domain is raised by Tenda itself and can only be resolved when you are connected to this router. When connected to data, it doesn't respond when enabled, so don't think it's broken.

enter, enter your login password first (the old model defaults to admin; the new model may require you to set one for the first time you enter). Looking at the interface, the new and old menus look quite different:

the older AC10 and AC9 generations, click "WiFi Name and Password" in the left menu, and the 2.4G and 5G tabs each have a password box. The new AX12 PRO and AC23 models have a single row of cards at the top. Click "WiFi Settings" to make the interface look nicer, but the logic hasn't changed.

the real key is the "dual-frequency selection" check. Hooked, two bands share one name and one password, change one to make it fully effective; No checkbox, each band is independent. both password boxes must be filled in, and the same must be provided. Otherwise, when switching between bands, the phone will think the password is incorrect. I fell into this trap before: I only changed the 2.4G slot, but my mother-in-law's phone connected to 5G in the living room and worked fine, but as soon as she switched to 2.4G in the bedroom, the connection immediately dropped. She called to say the router was broken, and I made a trip before realizing it was my own fault.

click save, no need to restart the router, it takes effect immediately.

after changing the password, the robot vacuum disconnected from the internet

changing the password, all the wireless devices at home will disconnect. This is normal, not because the password has been changed. Just re-enter the new password on your phone, computer, or tablet. The real trouble lies with smart devices: robot vacuums, cameras, smart speakers—those without screens can't enter new passwords yourself. Reconfiguring the network basically means starting over.

my mother-in-law's house, I had a robot vacuum and a camera, and it took me twenty minutes to reconnect the network. Especially for devices that only recognize 2.4G, no matter how good your new password is, it won't even be able to access 5G signals. I wrote a separate article about troubleshooting network configuration failures: robot vacuum always shows network connection failure when it can't connect to WiFi. So before you start, check how many of these devices you have at home, pick a time when you don't need a robot vacuum, and then make the upgrades. Don't start work on Friday nights like I did.

App can't bind to the router, try these three tricks one by one

first-time app users often get stuck in the binding step. I've encountered three situations:

First, if the phone isn't connected to the router's WiFi, if it's connected to data or a neighbor's home network, the app won't detect the device. Connect the WiFi first.

second, the router is too old. The old AC9 firmware didn't support app management at all. Upgrading might fix it, but if you find it troublesome, just go for the web route and change it as usual.

third, if your phone has a VPN or proxy, local devices find that layer is blocked, and apps can't find the router. Close it and open the app again.

trying all three tricks still doesn't work; the web route is always a safety net, and everyone has a browser. If you can't even open the tendawifi.com and the management pages of 192.168.0.1, then it's not about changing the password, but rather the login portal itself is faulty. Go to the article about 'can't open or troubleshoot': what to do if you can't open or enter 192.168.0.1.

why is it worth regularly changing passwords? Here's a sequence list at the end

back to the reason for changing the password. The neighbors who can access the internet either have passwords that are too simple and are found in the dictionary, or they have told the renovation workers and relatives who came to live there once and never changed them again. An 8-digit pure numeric password is basically a bare run against a network card; if you want to swap, switch to a 10-digit or mixed alphanumeric password. Anti-Unauthorized Penetration Tips include turning off SSID broadcasts and binding MAC addresses. I've gathered them all in my article: WiFi Anti-Scraper Troubleshooting .

Give a sequence chart at the end; follow it and it's easy to get confused:

Oh, right, after changing it, write down the new password. After my mother-in-law called for the third time asking what my password was, I bought a sticker and wrote it down and stuck it on the back of the router—this trick works better than any password management software, provided the router isn't placed on the windowsill.
