The security of your home network directly depends on the complexity of the access key installed on your router. The default passwords pre-installed on ISP devices are often too simple or publicly available in databases. If you use the default passwords, any neighbor with minimal knowledge can access your internet, which can result not only in traffic loss but also in risks to your personal data.
In this article, we will examine in detail the process of changing the encryption key on equipment. RostelecomThe procedure does not require in-depth knowledge of network technologies, but it does require careful attention when entering data into the web interface. Regardless of the model of your device, whether Sagemcom, Sercomm or Eltex, the logic of actions remains similar, although the visual design of the menu may differ.
Before you begin, make sure your device (laptop, smartphone, or tablet) is connected to the router. This can be done via Wi-Fi or via an Ethernet cable, which is a more secure option. A wired connection ensures you won't lose access to the router's admin panel while changing the password.
Preparing to change security settings
The first step is to gather the necessary information to log into the control panel. You will need the gateway IP address and administrator credentials. By default, the equipment Rostelecom the most commonly used address 192.168.1.1 or 192.168.0.1This information is often found on a sticker on the bottom of the device, along with the login and password for initial login.
If the sticker has been erased or the data has been changed previously and you don't remember it, you may need to reset your device to factory settings. This is a last resort and will return all settings, including the network name and Wi-Fi password, to their original state. To reset, you typically press and hold the button. Reset on the rear panel for 10-15 seconds with the power on.
It's also important to prepare a new password in advance. It should be complex enough to prevent brute-force attacks, yet memorable. It's recommended to use a combination of uppercase and lowercase letters, numbers, and special characters. The password should be at least 8-10 characters long.
⚠️ Note: Changing Wi-Fi settings will disconnect all connected devices. You will need to reconnect smartphones, TVs, and laptops using a new security key.
Login to the router's web interface
Open any modern browser on the connected device. Enter the router's IP address in the address bar. Don't confuse the address bar with the Yandex or Google search bar—enter the numbers in the URL field. After pressing Enter, an authorization window will appear.
Enter your login and password. For most models Sagemcom And Sercomm from the provider the standard pair is admin And admin, or login admin and a unique password indicated on the sticker (often designated as password or admin password). If you changed this data previously and forgot it, only a hard reset will help.
After successful authorization, you will be taken to the main page of the control panel. The interface can be presented as a list of menu items on the left or as a tile-based interface. We are interested in the section responsible for the wireless network. It may be called Wi-Fi, WLAN, Wireless network or Network.
What should I do if the page doesn't load?
If your browser says "Unable to access the site," check that you've entered the IP address correctly. Also, make sure your computer's network card is set to obtain an IP automatically (DHCP). Sometimes the browser may block access due to security certificates. In this case, try incognito mode or a different browser.
Configuring wireless network settings
In the settings menu, find the subsection related to basic configuration or security. Depending on your firmware version, the path may look like this: Wi-Fi → Basic Settings or WLAN → SecurityThis is where the field for changing the access key is located.
Pay attention to the parameter SSID (Service Set Identifier). This is the name of your network that other users see when searching for Wi-Fi. While changing the name isn't required, it's good network hygiene to avoid using a default name like "RT-WiFi_2839."
The main element of the setting is the field WPA Pre-Shared Key, Passphrase or simply PasswordDelete the old characters and enter the combination you've created. Make sure your keyboard layout matches the selected language, as case is important.
An important parameter is the encryption method. In the field Security Mode or Authentication a protocol must be selected WPA2-PSK or WPA3Using an outdated standard WEP or open mode (None) makes your network vulnerable to hacking in minutes.
☑️ Check before saving
Save changes and reboot
After entering all the data, you must click the button Apply, Save or ApplyOn some router models, changes take effect immediately, while on others, a reboot is required. If the interface offers a button Reboot or Reboot, be sure to complete this action.
During a reboot, the router updates the configuration file and restarts the wireless module. During this time, the internet will be unavailable. The device's indicator lights may flash erratically—this is a normal part of the system boot process.
After the router has fully booted (usually 1-2 minutes), try finding your network in the list of available connections on your smartphone or laptop. When you try to connect, the system will ask for a new password. Enter it and verify the connection is successful.
⚠️ Important: If devices are unable to connect after changing the password, try "forgetting the network" (deleting the network profile) on the router or client device and then reconnecting. Old saved data may conflict with the new security settings.
Features of different router models
The interfaces of different devices can vary significantly. To make things easier, we've prepared a table with typical settings paths for popular models provided by your provider.
| Router model | Entrance address | Path to Wi-Fi settings | Standard login/password |
|---|---|---|---|
| Sagemcom [email protected] 1744 | 192.168.1.1 | Advanced Setup -> Wireless -> Security | admin / admin |
| Sercomm RV899 | 192.168.0.1 | Local Network -> WLAN -> Security | admin / (indicated on the sticker) |
| Eltex NTU-RG-140 | 192.168.0.1 | Network -> WLAN -> Security | admin / admin |
| Upvel UR-326N4G | 192.168.10.1 | General -> Wireless -> Security | admin / admin |
Models Sagemcom often have a simplified interface, where the main settings are located on the main screen. While Sercomm And Eltex may require going to advanced settings (Advanced). Don't be afraid to explore the menu, but avoid sections related to VLAN or WAN, if you are not confident in your actions.
Some new models support control via a mobile app Wink or My RostelecomIn this case, you can change your password directly from your phone, without logging into the web interface via a browser. This is a convenient method, but it requires linking your device to your personal account first.
Recommendations for creating a strong password
Securing your network isn't just a formality. A weak password allows attackers not only to use your internet but also to intercept your traffic, gaining access to website passwords, banking information, and personal correspondence.
Avoid using obvious combinations such as sequences of numbers (12345678), repeating characters (aaaaaaaa) or dates of birth. Also, avoid using simple dictionary words that are easily found by special programs.
An ideal password should be a random string of characters. A good example: G7#mP9$vL2It's difficult to remember such a combination, so it's better to use a base phrase transformed according to your rules. For example, the phrase "I love walking in the park 2026" could become Lgvp_2026!.
Changing your password regularly (every 3-6 months) significantly reduces risks. If you have guests for whom you temporarily changed the password or granted access, it's best to update the access key immediately after they leave.
⚠️ Warning: The WPS (Wi-Fi Protected Setup) protocol, which allows for connection by pressing a button, is often vulnerable. If you don't need the quick connection feature, we recommend disabling WPS in your router settings for increased security.
Frequently Asked Questions (FAQ)
What happens if I forget my new Wi-Fi password?
If you've forgotten the password for your Wi-Fi network, you can find it in the settings of an already connected computer (in the wireless connection properties) or in the router's web interface by logging in via cable. If you've forgotten the password for accessing the router's settings (admin), the only solution is to reset it using the Reset button.
Is it possible to change the password via phone?
Yes, this is possible. Your phone must be connected to the router. You can access the settings through the mobile browser or use the provider's official app if your model supports remote control.
Why did the Internet become slower after changing the password?
Changing your password itself doesn't affect speed. However, if you've changed the broadcast channel or encryption standard to a less powerful one (for example, from WPA2 to WPA3 on an older device), speed may drop. Also, check to see if anyone else connected before you changed your password and hogged the channel.
Do I need to change the password for logging into the router (admin)?
Yes, this is critically important. The default password admin Everyone knows this. If an attacker gains access to your router settings, they can redirect your traffic to phishing sites or block the device. Change the administrator password in the "System" or "Management" section.
How often should I change my password?
Cybersecurity experts recommend updating access keys for critical services and home networks at least every six months. However, if you have a truly complex password (15+ characters, including special characters), the frequency may be reduced to once a year.
