Forgot your home Wi-Fi password, and your router Mercusys Won't connect new devices? This situation is familiar to many, especially if someone else set up the network or the last login was months ago. Fortunately, the manufacturer has provided several ways to restore access, and most of them don't require technical skills.
In this article we will look at all official methodsHow to find out the Wi-Fi password Mercusys — from basic (look at the router sticker) to advanced (extract data from a configuration backup). You'll also learn what to do if standard methods don't work, and how protect the network after restoring access to prevent the problem from recurring. The instructions are relevant for the following models: Mercusys Halo, AC1200, MR70X, MR90X and other series from 2020 to 2026.
Before you begin, make sure you have physical access to the router—without this, some methods will be unavailable. If the device is rented from a provider (for example, Rostelecom or Beeline), first check the contract: sometimes the password is written in the documents.
1. The password on the router sticker is the fastest way
The first thing to do is inspect the router bodyOn most models Mercusys (as with other brands of the group TP-Link) The factory Wi-Fi password is indicated on the sticker located:
- 📦 On the bottom panel of the device (under the feet or next to the serial number).
- 🔄 On the back side, if the router is vertical (for example, Mercusys MR60X).
- 📋 Inside the box, if the sticker on the router has worn off (look for the connection data sheet).
Look for fields Wi-Fi Password, Key or Password. Typically, this is a combination of 8-12 characters, including numbers, letters (in mixed case), and sometimes special characters. For example: 12345678A or Mercusys_5G_abc.
Important: This method only works if you did not change the password After initial setup. If the network has been renamed or secured with a new key, the sticker is useless—the data on it refers to the factory settings.
⚠️ Please note: On some models (eg. Mercusys Halo S12) the sticker may contain WPS PIN code instead of a password. This is not the same thing — PIN is used for quick connection via WPS, not for network authorization.
2. Router web interface: how to log in and find the password
If the sticker doesn't help, the next step is log into the router control panel via a browser. To do this:
Connect your computer or phone to the router via cable (recommended) or via Wi-Fi (if you remember the old password).
Open your browser and type in the address bar
melogin.cn(for new models) or192.168.0.1(universal IP). ClickEnter.Enter your username and password to log in. The default is:
- 🔑 Login:
admin - 🔑 Password:
adminor an empty field (depending on the model).
- 🔑 Login:
If the data is not suitable, look for it on the same router sticker (field Login Password).
After logging in, go to the Wi-Fi settings section. The path may vary depending on your firmware:
- 📶
Wireless (2.4GHz/5GHz) → Wireless Security - 🔒
Network → Wi-Fi → Wireless Security - ⚙️
More → Wi-Fi Settings
Look for the field Password, Password or PSK PasswordThe current network key will be displayed here. If the symbols are hidden by dots, click the eye icon (👁️) or check the box. Show Password.
Connect to the router via cable|Check the IP address in the network settings|Find the default login/password|Update the browser to the latest version-->
⚠️ Attention: If you have previously changed your control panel login details and have forgotten them, you will have to reset the router to factory settings (See Section 5). There is no other way to restore them. Mercusys does not provide the function of resetting the admin password via email or SMS.
3. Mercusys mobile app: convenient, but doesn't always work
The manufacturer offers an official application Mercusys (available for Android And iOS), which simplifies router management. To view the password through it:
Download the app from Google Play or App Store (Name:
Mercusys).Register an account (if you haven't done so yet) or log in using an existing one.
Add your router to the app by scanning the QR code from the sticker or entering the serial number.
Go to the section
Wi-Fi→Security settings. The password will be displayed in the field.Password.
Advantages of the method: There is no need to connect to the router via cable; you can manage the network remotely (if the function is enabled).
Cons: The app may not recognize older models (before 2021) or require a firmware update.
If the router is not detected, try:
- 🔄 Restart your router and phone.
- 📶 Connect to the router's network directly (even without the Internet).
- 📱 Update the app to the latest version.
4. Extracting the password from the configuration backup
This method is suitable if you have previously saved the router settings into a backup file (for example, when transferring the configuration to a new router). The file has the extension .cfg or .bin and contains all parameters, including passwords.
To extract data:
Locate the backup file on your computer (usually it's called
Mercusys_backup_YYYYMMDD.cfg).Open it in any text editor (for example, Notepad++ or VS Code).
Find strings using search (
Ctrl+F):wpapsk— password forWPA/WPA2.ssid— network name (will help to identify the required block).
Warning: The password in the file may be encrypted. If you see a set of characters instead of readable text (for example, a1b2c3d4e5==), use online decoders for base64 or MD5 (but this does not guarantee success - Mercusys uses its own encryption).
| Router model | Backup format | Is it possible to extract the password? |
|---|---|---|
| Mercusys AC1200 (MR60X) | .cfg (text) |
Yes, in the open |
| Mercusys Halo H30G | .bin (binary) |
No, decoding is required |
| Mercusys MR70X | .cfg (encrypted) |
Partial (SSID only) |
| Mercusys MW301R | .dat |
Yes, via HEX editor |
5. Resetting the router to factory settings is the last chance
If none of the previous methods worked, the only thing left is full reset (hard reset). This will return the router to its "out of the box" state, including default password (indicated on the sticker).
Instructions:
Find the button on the back of the router.
Reset(usually it is recessed into the body).Take a paper clip or a toothpick and press and hold the button 10-15 secondsuntil the indicators start flashing.
Release the button and wait for the reboot (1-2 minutes).
- 🔄 Network name (
SSID) and the password will become factory default (see sticker). - 🔌 All personal settings (including
PPPoE,IPTV,Guest network) will be deleted. - 📡 You may need to reconfigure your connection to your provider (login/password for the Internet).
- 🖥️ View saved passwords on your device:
- On Windows: open
Control Panel → Network and Sharing Center → Manage wireless networks, select your network and clickProperties → Security → Show input characters. - On Android: use apps like WiFi Password Viewer (root rights required).
- On MacOS: open
(Keychain Access), find the network name and open properties.
- On Windows: open
- 🔧 Telnet/SSH connection: some models Mercusys allow you to connect via console and run a command
cat /etc/config/wirelessto view the configuration. Dangerous! Incorrect commands may damage the router. - 🔍 Traffic analysis: using programs like Wireshark It is possible to intercept authorization packets (if someone is connected to the network), but this is difficult and illegal without the owner's consent.
- 📝 Keep your password in a safe place: use password managers (KeePass, 1Password) or write it down in a notebook (but not on the router sticker!).
- 🔄 Set up a guest network: in routers Mercusys there is an option
Guest networkwith a separate password - give it to your friends, but keep your main network secret. - 🔐 Use complex passwords: a combination of 12+ characters with letters, numbers and signs (for example,
Mercusys!2026_Router) more reliable than12345678. - 📱 Link your router to your Mercusys account: This will allow you to manage the network through the application and restore access without a reset.
- 🔄 Update your router firmware regularly (but check reviews of the new version first!).
- 📡 Disable
WPS(vulnerable protocol) in security settings. - 🔍 Enable
MAC address filtering, if you want to limit the range of devices that can be connected.
After reset:
⚠️ Please note: On some models (eg. Mercusys Halo S12) reset button Reset Works only when the power is on. If the indicators don't flash, try holding the button longer (up to 20 seconds) or power cycling the router during the reset.
What should I do if the Internet doesn't work after a reset?
If the router does not connect to the Internet after resetting, check:
1. Connection type (usually PPPoE or Dynamic IP) - check with your provider.
2. Login and password to access the network (they could have been entered by the wizard during setup).
3. Cable - Make sure it is connected to the port WAN (usually highlighted in blue).
If the settings are lost, use the quick setup wizard in the web interface (melogin.cn).
6. Alternative methods: for experienced users
If standard methods don't help, you can try advanced options, but they require technical skills:
Warning: Using SSH/Telnet or intercepting traffic may disrupt license agreement Mercusys and cybersecurity laws. These methods are provided for educational purposes only.

FAQ: Frequently Asked Questions about Mercusys Passwords
Is it possible to find out a Wi-Fi password without accessing the router?
No, unless you have physical access to the router or the device that was previously connected to this network. All official methods require either removing the sticker on the router, accessing its settings, or resetting it.
The exception is if the network is saved on your phone/laptop (see section 6).
Why doesn't my router connect to the internet after a reset?
Reset deletes all settings, including data for connecting to the provider (login/password PPPoE, VLAN ID etc.). You need:
- Check the connection parameters with your provider (they may be included in your contract).
- Go to the router's web interface and reconfigure it.
WAN-compound.
If you're unsure, call your operator's support team - they'll help you over the phone.
Is it possible to recover the password if the router is broken?
If the router does not turn on or does not respond to a reset, retrieve the password impossibleThe only solution is to replace the device and set up a new network.
If the problem is with the firmware (the router turns on but doesn't boot), try flashing it in emergency mode (look for instructions for your specific model on forums).
What password should I set so that it is easy to remember but difficult to crack?
Use pass phrase — a combination of 3–4 random words with numbers and symbols. Examples:
Coffee! Umbrella_2026_Merkus5 Years_Dog? WiFi_Fast
Such passwords are easy to remember, but difficult to brute-force.
What should I do if my ISP has blocked access to my router settings?
Some operators (eg. MTS or Beeline) block the web interface of rented routers. In this case:
- Try to log in via
Telnet(if the port is open). - Contact your provider's support team to request access or reset your password.
- If the router is yours (purchased, not rented), perform a factory reset.
