• For Sagemcom: Network → WLAN → Security
• For Sercomm: Wireless → Basic Settings
• For Huawei: WLAN → WLAN Basic Configuration

• Save changes button Apply, Save or ApplyThe router will reboot (takes 1–2 minutes).

After rebooting, reconnect your phone to Wi-Fi using the new password. If the settings page doesn't open, check:

• 🔄 The entered IP address is correct (without http:// or www).
• 📶 Connecting the phone to the router's network (if via Wi-Fi).
• 🔒 Disable VPN or proxy in your phone settings—they may be blocking access.

Correct IP address (192.168.1.1 or 192.168.0.1)|

The phone is connected to the Wi-Fi router (or mobile Internet is disabled)|

No VPN/proxy in phone settings|

Try a different browser (Chrome, Firefox, Safari)|

Reboot the router (remove/insert the power for 10 seconds) -->

3. Method 2: Using the Rostelecom Personal Account application

If logging in via a browser seems complicated, you can use the official app Rostelecom Personal Account (available for Android And iOS). This method is more convenient, but it doesn't work on all router models—it only works if the device supports remote management via a provider account.

Instructions:

1. Download the app from App Store or Google Play and log in using your Rostelecom contract number.
2. Go to Services → Internet → Wi-Fi Settings (the name may differ in new versions of the application).
3. Select your Wi-Fi network (if the router supports dual-band, there will be two networks: 2.4 GHz and 5 GHz).
4. Click "Change Password" and enter the new security key. Confirm the action.
5. Wait for the settings to be applied (the router will reboot automatically).

The advantages of this method:

• ✅ No need to remember the IP address or administrator login/password.
• ✅ Intuitive interface.
• ✅ Ability to manage other tariff settings (for example, connect IPTV or change the speed).

Flaws:

• ❌ Does not work with all router models (for example, older ones) D-Link or TP-Link from Rostelecom may not be supported).
• ❌ Requires authorization in your personal account (if you forgot your password, you can recover it via SMS).

⚠️ Attention: In some regions, the Wi-Fi control feature via the app may be disabled. If you don't see the "Wi-Fi Settings" section, use the browser method (Section 2).
