How do you change the WiFi password on a Mercury router on a mobile phone? No computer needed, just follow the button and it's done in 5 minutes

Mercury router and phone WiFi password change routes comparison diagram

neighbor's Mercury D268G WiFi password was stolen from the internet, and downloads at night have slow speeds. They asked me to help change the password. They don't have computers, so the whole process is operated on their phones, and it takes about five minutes to finish. It sounds simple, but as I tried to operate, I found that the newbie card was all about the details: the login box wouldn't work, the TV disconnected after changing the TV, the new password was too simple, and the next day it got scammed again. Writing while it's hot, since my home has a Mercury router and only has a phone, just follow the instructions.

let's start with the choice: whether it's an app or a web backend, both options can be changed

Mercury router, there are only two ways to change the WiFi password. the first is to install the 'Mercury Router' App. You can find it by searching the name in the app store. Once installed, connect to WiFi and the device will automatically recognize the device. The interface will show 'WiFi settings' directly, making password change the easiest way. The second rule is to log in to the 192.168.0.1 webpage backend your mobile browser. You don't need to install anything, which is suitable for situations where your phone has tight storage or the app won't open.

I chose an app for my neighbor. The reason is simple: their machines were previously bound to an app (done by the installer), and opening it brings you to the management interface, without even entering your login password. For the webpage backend, you have to enter the management password, which he had long forgotten about and had to go through the recovery process first, taking a detour. But I've tried both paths, so you can choose according to your situation.

By the way, if you're connected to someone else's Mercury and want to change your own, first make sure your phone is connected to your own router's WiFi before you act. The app and web backend only recognize the currently connected machine; if you connect to the wrong WiFi, the device you modify is someone else's (of course, you can't access without a password).

Route 1: Change your password in the Mercury Router app, tap a few times to finish

Step

: Search for 'Mercury Router' in your app store and make sure the developer is 'Shenzhen Meikexing Communications.' Don't install third-party knockoff versions. After installing and opening it, the app prompts you to connect to the router's WiFi. After connecting, there are two situations: previously bound , go directly to the management interface; that haven't been bound before, the first time you need to enter the management password (the password you log in to 192.168.0.1, forgot how to recover it. I wrote an article about how to recover it, see the about the Mercury initial password , then scroll to the section on app recovery).

Step two, after entering the interface, click the "Tools" tab at the bottom, tab and find "WiFi Settings" (some versions call it "Wireless Settings"). Inside are the WiFi names and password boxes for the two frequency bands. The D268G is a dual-band machine, with one line each for 2.4G and 5G. My neighbor's family needed to change the password for the whole group, so they changed both—setting the two frequency bands to the same password, so the elderly family wouldn't have to remember two sets when switching back and forth.

Step 3: Clear the old password box, enter the new one, and click Save . The moment you save, the phone will disconnect WiFi (the name hasn't changed, but the password has changed, and the phone is still connected with the old password). After a few seconds, the phone will automatically pop up a new password input box. Enter the new password and reconnect, and you're done. If you order quickly, the whole process takes three minutes.

Method 2: Log in to 192.168.0.1 in your mobile browser and change the

those who don't want to install the app should go for this one. Open your mobile browser. Note that it is address bar not a search box—enter 192.168.0.1 and press Enter. Here's a high-frequency pitfall: some Android browsers automatically add the HTTPS prefix and say 'Your connection is not private.' Manually change the address to http://192.168.0.1 and press Enter to enter. Pitfalls related to entry points (address bar entered as search, gateway changed, wrong WiFi) I previously wrote about a thorough investigation of six different situations. If you can't open this step, check out the 192.168.0.1 login entry .

After

enter, enter the management password to log in. Then find "Wireless Settings" or "WiFi Settings" menu (the Mercury website backend uses slightly different firmware versions, but both are in the primary or secondary menu, with the WiFi ripple icon). Open a sub-item like "Wireless Security Settings," and inside there is a PSK password box—this word sounds intimidating, but it's actually the WiFi password. Clear the old and replace the new, then click Save. After saving in the webpage backend, some models will prompt "Effective after reboot." Follow the prompt to restart the router (there is a restart button in the backend, no need to cut off the power).

phone will also disconnect after modifying it; just reconnect and enter the new password. The web route is two steps more than the app (find the menu, may need to restart), but the advantage is you don't have to install anything, the interface is complete, and later you need to change channels and set speed limits in the same backend, which is convenient.

can't connect anymore, how do you fix it? There are two situations where you can't get in

some people want to change their password when WiFi can't connect to their —for example, forgetting the password or suspecting someone was trying to change it. At this point, neither the app nor the website works, because the phone isn't connected to the router at all. Two methods:

first, use network cables to . Pull out a network cable, plug one end into the router's LAN port (any one in the yellow row), and the other end into your laptop. The computer can log in directly to 192.168.0.1 without WiFi. If you don't have a computer, some Mercury models support USB to Ethernet for your phone, but buying a dedicated adapter isn't worth it.

second, reset and then reset the . When the device is powered on, hold the SIM ejector pin down the reset port for more than 8 seconds. When the light turns on completely, release the router. The router will be restored to factory, WiFi will change to its passwordless default name (the string at the beginning of MERCURY_). When the phone is connected, a settings wizard will automatically pop up, where you can reset the WiFi name and password. The trade-off is that you have to refill your broadband account—so before you start, call your carrier's customer service, provide your installation address, and find your broadband account password for backup—it's free. I wrote about this step in detail and pitfalls in the reset section of the router password section. see here for .

After changing your password, don't forget to do these three things

changing the password doesn't end after clicking save. My neighbor didn't do a second thing that time, and the next day he was called over again.

reconnect all the devices at home : TV, robot vacuum, camera, smart speaker. All these devices that don't pop up the password box automatically have to be manually re-entered. Using a remote to enter passwords on TV boxes is the most annoying; slow down is the most annoying thing, but come one unit at a time.
don't set the management password and WiFi password : If you get the WiFi password, you can log in to the backend and change your password. WiFi passwords can be told to guests, but management passwords are not given to anyone.
the new password is set up decently a pure number under 8 digits can be tested by a dictionary in half a day. Letters + numbers with more than 10 digits, such as home address + birthday spelling backwards, don't use 12345678 or 88888888.

two days after the change, I checked the app or backend the connected device list . If there were unfamiliar devices, they were still on—just click disable immediately. Previously, when people succeeded in using the password, it was mostly because the password was too simple or was shared during broadband installation. After changing the password, all old devices were taken offline, and only after the list was clean did the change truly complete. A more systematic way to prevent internet access (turning off WPS, hiding SSID, binding MAC, etc.). I wrote an article about three-layer protection.

Frequently Asked Questions

changed the password and your phone can access the internet, but your computer can't find WiFi anymore? most likely, the old computer's network card only recognizes 2.4G. If you change the WiFi name for 2.4G, the computer will store the old name. Just make your computer forget about old networks and re-search; Or you can simply keep the 2.4G name unchanged and just change the password. If you have an older device at home, I recommend doing this.

App prompt "Router not bound"? phone is not connected to this router's WiFi, or the previous binding has been unbound. First, confirm the WiFi connection is paired, then go through the binding process again (enter the management password). If you forget your management password, first go to the app to retrieve it (you need the previously bound phone number still in use); if you can't get it back, you have to reset it.

webpage backend leads to an English interface? some older Mercury firmware versions default to English, with a Language option in the top right corner or the "System Tools" menu toggling Chinese Simplified, which does not affect the password change operations.
