Perhaps you've forgotten your router password or want to restrict unauthorized devices from accessing your internet. Fortunately, modern technology allows you to manage router directly from your smartphone screen, whether it be Android or iOS.
Change procedure password It doesn't require any special technical skills, but it does require careful input. Regardless of your device model—whether it's Sagemcom, Huawei or ZTE — the operating principle remains similar. You only need access to your router settings and a stable Wi-Fi connection.
In this guide, we'll walk you through the process in detail, address potential issues, and offer alternative management methods. Please remember that after changing the password, all devices will be disconnected from the network and will have to be reconnected with a new key. This is normal security system behavior.
⚠️ Note: Web control panel interfaces may vary slightly depending on your router's firmware version. If you don't see an exact match in the menu items, look for similar sections related to Wireless or WLAN.
Preparing your smartphone for router setup
The first and most important step is to connect your mobile device to the wireless network of the router you plan to set up. Make sure your phone is connected to the Wi-Fi network. Rostelecom, and doesn't use 4G or 5G mobile internet. If you're out of coverage or switch to mobile data, you won't be able to access the router's internal interface.
It is also recommended to find out the address for accessing the control panel in advance. In most cases, the standard address is 192.168.1.1 or 192.168.0.1This information is often found on a sticker located on the bottom of the device. You'll also find the factory-set login and password for system authorization there, if you haven't changed them previously.
Open any browser on your phone: Chrome, Safari or Yandex BrowserEnter the router's IP address in the address bar. If the page doesn't load, check that you entered the numbers correctly and that there are no extra spaces or characters in the address. Sometimes the browser may warn you that the connection is not secure—this is normal for local networks; simply agree to continue.
Login to the Rostelecom router web interface
After entering the IP address, you will be taken to the authorization page. Here, the system will request credentials to access the administrative panel. The default login is often admin, written in lowercase. The password can also be admin or a unique combination of characters indicated on the sticker.
If you've previously changed your login information and forgotten it, you'll need to reset your router to factory settings. There's a small button on the device for this. Reset, which must be held for about 10-15 seconds while the power is on. After rebooting, use the default data from the label.
Some modern router models Rostelecom Supports mobile app login. However, the classic web interface via a browser remains the most universal and reliable method, working even on older hardware. It's important not to confuse the Wi-Fi password with the admin password—they are different.
What should I do if the login page doesn't open?
Make sure you're connected to your router's Wi-Fi, not your mobile data. Try using incognito mode in your browser. Check that your phone isn't set to a static IP address—check your Wi-Fi settings to enable DHCP or obtain IP automatically.
Find the wireless network section in the menu
After successful authorization, you'll be taken to the main page of the control panel. The interface may look different, but the menu structure is the same. You need to find the section responsible for the wireless connection. It's usually called WLAN, Wireless, Wi-Fi or Wireless network.
Within this section, look for a subsection titled Basic, Security or SecurityThis is where the encryption and access key settings are located. Don't confuse this section with the PPPoE or WAN settings, which are responsible for connecting to your ISP—they don't need to be changed.
Pay attention to the parameter SSIDThis is the name of your network that other users see when searching for Wi-Fi. You can change it if you want to make the network more recognizable. However, our main goal is to WPA Pre-Shared Key or Password.
The process of changing your Wi-Fi password
Once you find the password field, delete the old character combination. Create a new, secure password that will be difficult for hackers to guess. We recommend using a combination of uppercase and lowercase letters, numbers, and special characters. The password should be at least 8 characters long, but 12 or more is preferred.
It is important to check the encryption type. In the field Security Mode or Authentication Type a protocol must be selected WPA2-PSK or WPA3Using an outdated standard WEP or open network (None) makes your internet vulnerable to hacking. If you have a different encryption type, be sure to change it to WPA2.
After entering your new password and selecting the encryption type, scroll down the page. Find the button Apply, Save or SaveClick it. The router will begin applying the new settings. Your internet connection may be temporarily interrupted during this process.

| Router model | Menu section | Subsection | Password field name |
|---|---|---|---|
| Sagemcom F@st 2804 | Advanced Setup | Wireless / Security | Pre-Shared Key |
| Huawei HG8245 | WLAN | WLAN Basic Configuration | WPA Pre-Shared Key |
| ZTE F660 | Network | WLAN / Security | WPA Passphrase |
| Eltex NTU | Wireless | Security | Passphrase |
As you can see from the table, the terminology may vary, but the essence remains the same. If you can't find an exact match, search for security-related words (Security) or key (Key, Pass).
In some models ZTE or Huawei Settings may be divided into several tabs. Sometimes you need to switch the display mode from "Quick Setup" to "Advanced" to see all available options. Be careful when navigating the menu.
⚠️ Note: After pressing the save button, the router may reboot. Do not attempt to access the settings again immediately—give the device 1-2 minutes for the Wi-Fi modules to fully recover.
Setting up via the Home mobile app
An alternative and more convenient way for smartphone users is to use the official application House from RostelecomThis method doesn't require entering IP addresses or navigating through a web interface. The app automatically detects connected equipment and offers settings management.
To get started, download the app from Google Play or App StoreLog in using your account number or the phone number associated with your contract. If your router supports remote management, it will appear in the list of devices.
Select your router from the list and find "Wi-Fi Settings" or "My Network." Here you can change the network name and password in a couple of clicks. The app will automatically apply the settings and, if necessary, prompt guests to scan a QR code to quickly connect.
Possible problems and their solutions
Sometimes, after changing the password, your phone can't connect to the network. In this case, find your network in the list of available Wi-Fi networks on your smartphone, tap it, and select "Forget network" or "Delete profile." Then, reconnect using the new password.
Another common issue is that the router won't save settings. This can happen if you try to change settings while on a 5 GHz network, and the router switches to a different channel or standard when you reboot. Try configuring the settings while connected to a 2.4 GHz network.
If you see an IP conflict error message, check if another router or access point is sharing your internet connection. In more complex cases, when nothing else helps, you can contact your ISP's technical support, but usually the problem is resolved by rebooting your device and clearing the browser cache on your phone.
Remember that the security of your network depends on the complexity of your password. Simple combinations like 12345678 or qwerty They can be cracked with specialized programs in seconds. Use password generators or create complex but memorable phrases.
What should I do if I forgot my new password immediately after changing it?
If you changed the password and immediately forgot it, and the connection from your phone has already been lost, your only option is to physically access the router. You'll need to press the reset button on the device to restore factory settings. After that, the password will be reset to the one on the sticker, and you can change it again, making sure to write it down this time.
Is it possible to change the password without connecting to Wi-Fi?
Without connecting to the router's local network (via Wi-Fi or cable), you can't access its settings using the standard method. However, if the router is linked to your Rostelecom account and supports cloud management, you can change the password through the provider's website or mobile app using your mobile data connection.
Does changing your password affect your internet speed?
Changing your password itself doesn't affect your internet connection speed. However, if you change the encryption type from WPA2 to a less secure one, or vice versa, some older devices may experience instability. Also, if you have many unauthorized users connecting to your network, changing your password and disconnecting them may improve your speed.
