Many mobile internet users are familiar with the situation of needing to connect a new device to a wireless network but losing or forgetting the access key. Owners of 4G routers and USB modems with tethering capabilities often encounter the problem of the factory sticker being worn off, and remembering the password combination they created earlier is impossible. In this case, a logical question arises: how to quickly restore access and return devices to the network without losing data?
There are several proven methods to solve this problem, depending on the model of your equipment and the current status of the settings. MTS modem Allows you to manage security settings via a web interface or special commands, but it's important to proceed consistently. In this article, we'll cover all current methods for restoring access, from simple manipulations of the device's case to in-depth configuration via a browser.
Before taking any drastic action, it's worth noting that factory default data can often be found on the device itself. However, if you've previously changed security settings, this data will no longer be relevant. Attention! Attempts to guess the password may result in a temporary lockout of the device for security reasons, so it is best to use proven administration methods.
Search for factory data on the case and in the documentation
The easiest and fastest way to find the standard passcode is to carefully inspect the device itself. Manufacturers, including MTS and partners like Huawei or ZTE, are required to include unique information for each device on a special information sticker. This sticker is usually located on the back panel, under the removable cover (where the SIM card is located), or on the bottom edge of the device.
Look for the field with the name WPA Key, Wireless Key or simply PasswordThe SSID (network name) is often listed nearby, which by default matches the model name or has the prefix MTS_XXXX. If the sticker is still legible, you can enter this information into the WiFi settings on any device.
⚠️ Note: If you've ever changed your router settings through a browser, the information on the sticker is no longer valid. In this case, it won't help you connect, as user-defined changes take precedence.
In some cases, especially with USB modems in the "whistle" form factor, the sticker may be located on the removable battery or the inside of the cover. If you're using a stationary 4G router, also check the original box or warranty card—sometimes duplicate keys are printed there.
Login to the router's web interface to view settings
If the sticker is lost, the most reliable way is to log into the modem's control panel. To do this, you'll need a computer or smartphone already connected to the modem's network (via cable or WiFi), or a USB cable with the drivers installed. The default login address is usually 192.168.0.1 or 192.168.8.1.
Open any browser and enter the IP address in the address bar. The system will request a login and password to log into the admin panel. By default, MTS equipment often uses the login admin and password admin, or superuserThis information may also be found on the same sticker as the WiFi key, but in the "System" or "Login" section.
After successful authorization, you need to find the section responsible for the wireless network. The interface may vary depending on the model (Huawei E5577, ZTE MF90 etc.), but the logic is the same everywhere:
- 📡 Go to the menu Settings or
Settings. - 🔒 Select a tab WLAN, Wireless or
WiFi. - 🔑 Find the item WPA PreSharedKey or
Passphrase- your current key will be displayed there.
⚠️ Note: Firmware interfaces may be updated by your operator. If you can't find the required option, check the official instructions for your specific router model on the manufacturer's website.
In the window that opens, you'll not only see your current password, but also have the option to change it to a more complex and memorable one. Be sure to save your changes by clicking the button. Apply or SaveAfter this, all connected devices will require re-authorization with a new key.
Using a mobile app to control
Modern 4G routers from MTS often support control via special mobile applications, such as MTS Connect or AiLife (for Huawei devices). This method is especially convenient if you don't have a computer handy and your smartphone is already connected to the router's network.
The app automatically scans the network and prompts you to log in to the device. After authorization (often requiring an admin password, which is by default admin) takes you to the main screen with information about traffic and connected subscribers. In the settings menu, usually marked with a gear or three dots, you'll find the WiFi security section.
Here you can view the current access key and change it. The advantage of the app is that it often has a more intuitive and modern interface than the web version. Furthermore, the app makes it easy to check the list of connected "neighbors" and block unknown devices if necessary.
Factory reset
In a situation where the WiFi password is lost and you can’t log into the web interface (since the administrator password is also lost), there remains a radical but effective method - a full reset (Hard Reset). This procedure will return the modem to its out-of-the-box state, restoring the factory password indicated on the sticker.
To perform a reset, find the small hole on the case with the inscription Reset or RestoreIt can be recessed into the housing to prevent accidental pressing. You'll need a thin object: a paperclip, a toothpick, or a needle.
The order of actions should be as follows:
- Plug the modem into the network and wait until it is fully loaded (the indicators should be steady).
- Press and hold the button in the hole Reset within 10-15 seconds.
- Release the button when the indicators flash or the device reboots.
After rebooting, the network will be named as indicated on the sticker and will require the standard factory key to connect.
☑️ Checklist before resetting your router
Viewing a saved password on a connected computer
If you already have a Windows laptop or PC connected to your WiFi network, you can find the password directly from the system, without having to access the router settings. Windows stores the keys for every network your computer has ever connected to.
To do this, open "Settings" (via the Start menu), go to "Network and Internet," then select "Network and Sharing Center" (or "Advanced network settings"). Click the name of your wireless network, then select "Wireless network properties."
In the window that opens, go to the tab SecurityYou'll see a "Network Security Key" field with symbols hidden by dots. Check the box next to it. Show entered characters, and the system will show you the current password in clear text.
What should I do if the security tab is grayed out?
If you can't change settings or see your password, your account may not have administrator rights on this computer. Try logging in as an administrator or running Command Prompt as an administrator.

Wireless Network Security Tips
Once you've regained access, it's crucial to ensure your network is protected from unauthorized access. Default passwords are often too simple or widely known, making the network vulnerable to brute-force attacks.
It is recommended to set the encryption type WPA2-PSK or WPA3, if the device supports the new standard. Avoid using WEP encryption, as it is considered outdated and easily cracked. The password must contain at least 8 characters, including upper- and lower-case letters and numbers.
It is also worth disabling the function WPS in your router settings if you don't use it regularly. This technology simplifies connection, but creates a security hole, allowing attackers to brute-force your PIN. Regularly checking the list of connected clients in the web interface will help you spot intruders early.
Frequently Asked Questions (FAQ)
What to do if the admin/admin password doesn't work?
If the default login/password pair doesn't work, it's possible they were changed by the previous owner or you. In this case, the only solution is a hard reset using the button on the device.
Is it possible to find out the password via USB cable without connecting to the network?
Yes, when connecting a modem via USB, it is often detected as a network card or modem. You can access the web interface using the IP address, even if WiFi is disabled on the router, and view the wireless network settings.
Did the WiFi password reset when I changed the SIM card?
No, changing your SIM card from MTS or any other provider does not affect your WiFi security settings. The password remains the same unless you reset the router itself.
Where can I find my router's IP address if 192.168.0.1 isn't opening?
Try the address 192.168.8.1 or 192.168.1.1. You can also find out the default gateway via the command line (command ipconfig) on the connected computer - this is the router address.
