How to change the Wi-Fi name and password on a Rostelecom router: 3 proven methods

Changing the network name (SSID) and Wi-Fi password from Rostelecom — a standard procedure that may be necessary when equipment ownership changes, there's a suspicion of hacking, or simply to improve security. However, many users encounter difficulties: they can't find the necessary settings in their personal account, confuse the interfaces of different router models, or are afraid of accidentally resetting the configuration to factory settings.

In this article we will look at three official methods Wi-Fi data change: via router web interface, Rostelecom personal account And mobile applicationWe will pay special attention to the nuances for popular equipment models (Sagemcom [Fast] 5365, Sercomm RV6699, Huawei HG8245H) and typical errors that prevent new settings from being applied. You will also learn how to choose strong password and why you shouldn't use the default network name.

If you rent a router from a provider, all changes will remain even after a firmware update. Rostelecom does not reset user Wi-Fi settings during remote equipment maintenance.. Exceptions are cases of a complete reset of the device to factory settings.

1. Preparing to change Wi-Fi settings

Before you start changing SSID (network name) and password, make sure that:

• 🔌 The router is connected to a power supply and turned on (the indicator Power lights up green or blue).
• 💻 You have a device (computer, smartphone, tablet) connected to the router's network via cable or Wi-Fi.
• 📝 You know the current Wi-Fi password (if you're connecting over the air) or the login information for the web interface (usually found on the router's sticker).
• ⏳ Set the time for the procedure: when changing the parameters, all devices will be disconnected from the network for 1-2 minutes.

If you don't remember your Wi-Fi password but have access to your router via cable, you can reset it to factory settings by pressing the button Reset (usually recessed into the case and requires a paperclip). However, this is an extreme measure: after the reset, you will have to set up the internet connection again using the data from the contract with Rostelecom.

⚠️ Attention: If the router is rented from a provider, resetting it to factory settings may block internet access until the equipment is reactivated through support.

2. Method 1: Change via the router's web interface

This is a universal method that works on all router models, provided RostelecomThe interface may differ slightly, but the general algorithm remains the same.

Step 1: Login to the control panel

Open any browser (Chrome, Edge, Firefox) and enter one of the IP addresses in the address bar:

• 🌐 192.168.1.1 (the most common for routers Rostelecom).
• 🌐 192.168.0.1 (used less frequently, for example, on some models Huawei).
• 🌐 192.168.100.1 (for optical terminals GPON).

If none of the addresses open the panel, check the sticker on the back of the router - it contains the correct IP.

In the authorization window that appears, enter:

• 🔐 Login: admin (default for most models).
• 🔐 Password: admin or a unique code from a sticker (for example, RTKxxxxxx).

⚠️ Attention: If you previously changed the password for logging into the web interface and forgot it, the only way to restore access is to reset the router to factory settings.

Step 2: Find Wi-Fi settings

Once logged in, you'll need to find the wireless network settings section. The path may vary depending on your router model:

If your model is not in the table, look for tabs with the words Wireless, Wi-Fi, WLAN or Wireless network.

Step 3: Change SSID and Password

In the Wi-Fi settings section, you will see the following fields:

• 📛 SSID (or Network name) is the current name of your Wi-Fi network. Enter a new name (we recommend using Latin characters and numbers, without spaces).
• 🔒 Password (or Key, Password, WPA-PSK) is the current security key. Create a new password of length at least 8 characters, using capital letters, numbers and special characters.
• 🔄 Security type — choose WPA2-PSK (the most reliable option) or WPA3-PSK (if supported).

Example of a strong password: Rostelekom_2026!WiFi.

Changed the SSID (network name) | Set a new password (minimum 8 characters) | Selected the WPA2-PSK or WPA3-PSK security type | Checked that the "Enable Wi-Fi" checkbox is active

-->

After making changes, click the button Save, Apply or ApplyThe router will reboot, and all devices will be disconnected from the network. Reconnect using the new information.

3. Method 2: Change through your Rostelecom personal account

If you have access to personal account on the website RostelecomYou can change Wi-Fi settings without logging into the router's web interface. This method is convenient if you don't remember the control panel password or are worried about breaking something.

Step 1: Log in to your personal account

Go to the official website Rostelecom and log in to your personal account using:

• 📞 The phone number linked to the contract.
• 🔐 Password (if you don’t remember it, recover it via SMS).
• 🔑 Or data from the contract (login and password for accessing services).

Step 2: Find the hardware section

Find the tab in your personal account menu My services or Equipment. Next:

1. Select your tariff plan (if you have several).
2. Find the block Wi-Fi settings or Router management.
3. Click Change network settings.

If there is no Wi-Fi settings section, your router model does not support remote management via your personal account. In this case, use web interface (method 1).

Step 3: Editing and Saving

In the window that opens, you can:

• 📛 Edit network name (SSID).
• 🔒 Install a new one Wi-Fi password.
• 🔄 Select encryption type (recommended) WPA2-PSK).

After making changes, click SaveThe settings will take effect within 1–2 minutes. All devices will be automatically disconnected from the network. Please reconnect them with the new settings.

⚠️ Attention: Some features (such as guest network or parental controls) may not be available for editing through your personal account. To configure them, you'll need to use the router's web interface.

4. Method 3: Using the Rostelecom mobile application

For smartphone owners on Android or iOS The most convenient way to change Wi-Fi settings is through the official app. It automatically detects your router model and provides a simplified interface.

Step 1: Install and log in to the app

Download the app Rostelecom from the official store:

• 📱 Google Play for Android.
• 🍎 App Store for iOS.

Log in using your phone number or the login from the contract.

Step 2: Find the Wi-Fi section

In the main menu of the application:

1. Go to the section Internet.
2. Select Wi-Fi settings.
3. Click Change network settings.

If the app requests access to your location, allow it—this is necessary to determine nearby equipment.

Step 3: Editing and applying settings

In the window that opens:

• 📛 In the field Network name enter a new one SSID.
• 🔒 In the field Password Please enter a new key (minimum 8 characters).
• 🔄 Make sure the security type is set to WPA2-PSK.

Click SaveThe app will automatically reboot the router and apply the settings. All you need to do is reconnect to the network.

5. Typical mistakes and their solutions

Users often encounter problems when changing their Wi-Fi name and password. Let's look at the most common ones and how to resolve them.

Error 1: Settings are not saved

If after pressing Save changes do not apply:

• 🔄 Reboot the router (using the button on the case or via the web interface).
• 🌐 Try a different browser (for example, Mozilla Firefox instead of Chrome).
• 🗑️ Clear your browser cache or use incognito mode.
• 🔌 Check if the router's power was turned off while saving.

Error 2: Unable to log in to the web interface

If the page 192.168.1.1 does not open:

• 🔌 Make sure the cable is connected to the port LAN (Not WAN) on the router.
• 🌐 Check if the router's IP address has changed (you can find out via the command line: ipconfig for Windows or ifconfig for macOS/Linux).
• 🔒 Disable VPNs or proxy servers that may be blocking access.
• 🔄 Try connecting from another device.

Error 3: After changing the password, the Internet disappeared.

If your devices connect to Wi-Fi, but the internet doesn't work:

• 🔧 Check if your settings have been reset PPPoE (login and password for connecting to the Internet). They are specified in the contract with Rostelecom.
• 🌍 Make sure it is not activated in your router settings Parental control or MAC address filtering.
• 📡 Reboot your router and wait until the indicator lights up Internet.

What should I do if my router displays an "Invalid password" error?

The "Invalid password" error usually occurs if:

- Password is shorter than 8 characters.

- Invalid characters are used (e.g. Cyrillic, spaces, quotation marks).

- The mode is on WEP (outdated and unsafe).

Solution: Create a password using Latin letters, numbers, and symbols. !@#$%^&*, 8–32 characters long.

6. How to create a strong Wi-Fi password

A weak password is one of the main reasons for home network hacking. Hackers use automated programs to guess simple combinations, such as 12345678 or qwertyTo protect your network, follow these guidelines:

Rules for creating a secure password

• 🔢 Length: minimum 12 characters (optimally 16+).
• 🅰️ Use it uppercase and lowercase letters (For example, RostelekomWiFi2026).
• 🔢 Add numbers (not at the end, but in the middle of the word: Ro5telekomWi20Fi26).
• 💎 Turn on special characters: !@#$%^&* (For example, Rostelekom@WiFi#2026!).
• 🚫 Avoid obvious words: names, dates of birth, street names.

Examples of strong passwords

To avoid forgetting your password, write it down in a safe place (for example, in a password manager) KeePass or 1Password) or save it as a screenshot in a secure folder.

7. Additional settings for Wi-Fi security

In addition to changing the network name and password, we recommend configuring additional settings to protect against hacking and unauthorized access.

1. Disabling WPS

WPS Wi-Fi Protected Setup (Wi-Fi Protected Setup) is a convenient feature for quickly connecting devices using a PIN code, but it has critical vulnerabilities. Disable it:

• In the router's web interface, find the section WPS or QSS.
• Move the switch to the position Disabled.
• Save the settings.

2. Hiding SSID (not recommended)

Many people advise hiding the network name so that it is not visible in the list of available Wi-Fi networks. However, this does not improve safety, but only complicates connecting new devices. Instead, it's better to:

• 🔒 Use a complex password.
• 🔄 Enable MAC address filtering (if maximum protection is needed).
• 📡 Disable guest network, if it is not used.

3. Updating the router firmware

Outdated firmware may contain vulnerabilities. Check if your firmware is up-to-date:

1. In the web interface, find the section System or Update.
2. Click Check for updates.
3. If a new version is available, install it.

⚠️ Attention: Do not interrupt the firmware update process, as this may damage the router. Make sure the power supply is stable (preferably using a UPS).
