Changing the factory password for your wireless network is the first step you should take after installing your ISP equipment. The default combinations found on a sticker inside the device are often publicly available, making your network vulnerable to unauthorized access by unauthorized individuals.
In this article, we will take a detailed look at the process of changing the security key for your hardware. Rostelecom, which can be released under brands Sagemcom, Sercomm or your own logo RTYou'll learn how to access your router settings, select a strong encryption type, and create complex passwords that will protect your personal data from hacking.
The process takes just a few minutes but significantly improves the level of digital hygiene in your home. We'll cover both standard browser login and using a mobile app to manage the network.
Preparing to set up network security
Before changing security settings, you need to ensure a stable connection between your device (computer or smartphone) and the router. It's best to do this using a cable connection. LAN, since the wireless connection may be broken when changing the password or encryption type.
You will need to know the address to log into the admin panel. In most cases, for equipment Rostelecom the standard IP address is used 192.168.1.1 or domain name 192.168.0.1This information may also be duplicated on an information sticker located on the bottom of the device.
If you've previously changed your login and password for the settings interface itself, use them. If the settings were reset or not changed, the factory settings, which are often a combination, will work. admin / admin or a unique combination from the same sticker.
⚠️ Important: Make sure you're connected to your own network. If you change settings while within range of a neighboring router with a similar name, you could block access to someone else's device or become confused by the interfaces.
Modern router interfaces may differ depending on the model and firmware version, but the operating logic remains the same. It's important to have the device you'll be using to make changes on hand and ensure it's charged if you're using a laptop or tablet.
Login to the router control panel
Open any convenient web browser: Google Chrome, Yandex Browser, Mozilla Firefox or SafariIn the address bar, where you usually enter the website address, you need to enter your router's IP address. Don't confuse the address bar with the search bar, otherwise the browser will try to find this number online.
After pressing the key Enter The system will request authorization. In the window that opens, enter your login and password. For equipment Sagemcom And RT login is often used by default admin and password admin, or the data indicated on the device sticker.
If you've successfully logged in, you'll be taken to the main page of the web interface. Here, you can see your connection status, internet speed, and a list of connected devices. We're interested in the section responsible for your wireless network.
In some cases, especially on older models or when using specific firmware, the interface may not load. Try clearing your browser cache or using incognito mode. It's also worth checking whether you have a static IP address set on your network card that conflicts with your router's address.
Finding Wi-Fi network settings
After authorization, the control menu will open. The menu structure depends on the hardware manufacturer. On devices Sagemcom The settings you are looking for are usually located in the section Network (Network) -> WLAN (Wireless Network) -> Security (Safety).
For routers Sercomm the path may look different: tab Wi-Fi -> Basic settings or Security settings. In interfaces RT (provider's own line) often uses a simplified menu, where all wireless network parameters are combined into one group WLAN.
You need to find a field called SSID (network name) and a password entry field, which may be designated as Pre-Shared Key, WPA Passphrase or simply PasswordThis is where the access key is changed.
Pay attention to the parameter Security Mode or Authentication TypeFor maximum protection and compatibility with all modern devices, it is recommended to select the value WPA2-PSK or WPA/WPA2-PSKUsing an outdated standard WEP unacceptable, since it can be hacked in a few seconds.
Modern firmware may also have this option WPSIt is recommended to disable this feature in adjacent tabs, as it is a known vulnerability that allows one to bypass the Wi-Fi password without knowing it.
Create a strong password and save it
When creating a new password, avoid obvious combinations such as sequences of numbers. 12345678, dates of birth, or simple words. A strong password should contain at least 8-10 characters, including uppercase and lowercase letters, numbers, and special characters.
In the password entry field (WPA Pre-Shared Key) Enter the combination you've created. The system may hide entered characters with asterisks for security. Carefully double-check the entered data, as a typo will result in loss of access, and you'll have to reconnect the devices.
After entering all the required parameters, be sure to click the button Save (Save) or Apply (Apply). In some interfaces, the button may be at the bottom of the page, while in others, it may be at the top of the menu.
After clicking the save button, the router may reboot the wireless module. At this point, all connected devices will lose internet connection. This is normal system behavior.
☑️ Password security check
If you change the password while connected to a Wi-Fi device, the connection will be disconnected immediately after the settings are applied. You'll need to find your network in the list of available networks and enter the new key.
Changing your password via the mobile app
For users who prefer to manage settings from a smartphone, the provider offers an app Rostelecom Wi-Fi (or Rostelecom.Dom). This method allows you to change your password without having to remember IP addresses and access the web interface.
Download the official app from Google Play or App StoreLog in using your personal account information or the phone number linked to your contract. The app will automatically find your router on the local network.
In the main menu of the application, select the section My network or Wi-FiThe current network name and password will be displayed there. You can edit the settings by clicking the edit or eye icon.
The advantage of the mobile method is its simplicity and the availability of additional features, such as creating a guest network or limiting access time for children. The app interface is more user-friendly and does not contain complex technical terms.
⚠️ Note: For the app to work, your smartphone must be connected to the Wi-Fi network of the router whose settings you want to change. Control may not be available via mobile data (3G/4G) without first setting up remote access.
After changing the password in the app, the router will immediately apply the settings. Previously connected devices will require re-entering the new access code.
What to do if you forgot your settings password
The situation when the password for entering the control panel (192.168.1.1) has been changed and forgotten, a common occurrence. In this case, accessing the settings and changing the Wi-Fi password through the browser will not work.
The only sure solution in this situation is to reset the device to factory settings. On the back of the router, next to the ports or power button, there is a small hole with the inscription Reset or Reset.
To reset the router, plug it in. Take a thin object (like a paperclip or toothpick) and press the button inside the hole. Hold it for 10-15 seconds until the front panel lights flash simultaneously or the router begins to reboot.
After the reboot, all settings, including the Wi-Fi password and administrator password, will be reset to the factory defaults listed on the sticker. You will be able to log in and set up the network again.
Consequences of a factory reset
After resetting, the router will lose all user settings. If your provider uses specific parameters (VPI/VCI, PPPoE connection type with login and password), the internet may not work automatically. You will need to re-enter the PPPoE authorization information provided in your contract or wait for automatic configuration from your provider's server, if supported.
It's important to understand that resetting is a last resort. Before doing this, always check to see if the password is written on a sticker that may have been placed on the router by the previous owner or a technician during installation.

Frequently Asked Questions (FAQ)
Is it possible to change a Wi-Fi password without having a computer connected?
Yes, this is possible. You can use a smartphone or tablet connected to the router's network via Wi-Fi. It's also possible to configure it through your provider's mobile app, if you have one installed and configured.
Why did the TV stop connecting to the network after changing the password?
The TV "remembers" the old password. You need to go to the network settings on the TV, find your home network, select "Forget network" or "Delete," and then reconnect using the new password.
How often should I change my Wi-Fi password?
Security experts recommend changing passwords for critical resources every three to six months. For a home Wi-Fi network, it's sufficient to change the password if you suspect a hack or if the number of residents or guests with access changes.
What should I do if my router displays "No Internet Access" after changing my password?
Changing your Wi-Fi password shouldn't affect internet access. If the issue persists, check to see if your PPPoE settings (username and password from your ISP) were reset or otherwise changed. Also, try rebooting the router using the power button.
Is it possible to set a password that consists only of numbers?
Technically, this is possible, but not recommended. A password consisting solely of numbers is easier to brute-force. It's better to use a combination of letters and numbers to increase encryption strength.
