⚠️ Attention: If the router is rented from Rostelecom, resetting may block access to some features. In this case, you'll need to call your provider's support to unblock them.

2. Login to the router control panel

To change the network name and password, you need to access the router's web interface. To do this:

1. Open any browser (Chrome, Firefox, Edge).
2. In the address bar, enter 192.168.1.1 or 192.168.0.1 (less often - 192.168.100.1).
3. Click Enter.

If the page does not open, check:

• 🔗 The correctness of the entered address (sometimes the provider changes the IP, for example, to 192.168.8.1 For Huawei).
• 🌐 No VPN or proxy in the browser.
• 🖥️ Connect to the router (if via Wi-Fi, try a cable).

After successfully logging in, you'll see a login window. Enter your username and password (the default ones are listed on the router's sticker). If the information doesn't work, it's likely that it's been changed previously—try remembering it or reset the settings as described above.

3. Find the Wi-Fi settings section

Router interface Rostelecom The menu structure varies depending on the model, but it's generally similar. Once logged in, look for sections labeled:

• 📡 Wi-Fi / Wireless network / Wireless
• 🔒 Security / Security
• ⚙️ Network settings / Network Settings

For example, in routers Sagemcom F@st 2804 the path looks like this: Home Network → Wi-Fi → Basic Settings.

IN Sercomm RV6699: Network → Wireless → Basic.

IN Huawei HG8045A: WLAN → Basic Configuration.

⚠️ Attention: On some models (Sagemcom 5364) settings 2.4 GHz And 5 GHz separated. If you want to change the settings for both frequencies, you'll have to repeat the steps in each section separately.

Where can I find my router model?

The model is indicated on a sticker on the back of the device. It usually begins with the manufacturer's name (Sagemcom, Sercomm) and ends with a digital code (for example, F@st 3804 v5).

4. Changing the network name (SSID)

Network Name (SSID) is what other devices see when searching for Wi-Fi. To change it:

1. In the section Wi-Fi (or similar) find the field Network name / SSID / Network Name.
2. Delete the old name and enter a new one. Recommendations:
   • ✅ Use Latin (not Cyrillic!).
   • ✅ Length - up to 32 characters.
   • ❌ Avoid personal information (eg. Ivanov_WiFi).

Do not change the parameter Hide SSID (Hide SSID), if you are not sure - otherwise the network will become invisible to new devices.

Important: If you have a dual-band router (2.4 GHz + 5 GHz), you can make the network names the same (for example, MyWiFi_2G And MyWiFi_5G) or different ones. Identical names are more convenient for devices that automatically connect to a more stable frequency.

After changing your name, scroll down to the bottom of the page and click Save / ApplyThe router will reboot and you will temporarily lose connection.

Make sure the new network name is unique (not the same as your neighbors)|

Check that the name does not have spaces at the beginning/end|

Remember or write down a new name to connect other devices|

Save settings on all frequencies (2.4 GHz and 5 GHz)-->

5. Setting a new Wi-Fi password

A Wi-Fi password is a security key that protects your network from unauthorized connections. To change it:

1. In the section Security (Security) find the field Password / Password / Pre-Shared Key.
2. Enter a new password. Requirements:
   • 🔐 Minimum length — 8 characters (better 12+).
   • 🅰️ Use letters different registers (Az), numbers (0-9) and symbols (!@#$%).
   • ❌ Don't use simple combinations like 12345678 or qwerty.

Select the encryption type - WPA2-PSK (recommended) or WPA3-PSK (if supported).

Example of a strong password: Green$Tree77!Moscow.

After entering the password, remember to save the settings. The router will reboot, and all connected devices will be disconnected. To access the internet again, you'll need to enter the new password on each device.

6. Additional settings for stable operation

In addition to the username and password, you can optimize other parameters to improve network speed and reliability:

• 📶 Wi-Fi channel: If the network is slow, try manually selecting a channel (for example, 6 or 11 for 2.4 GHz). Use apps like Wi-Fi Analyzer (Android) to find the least crowded channel.
• 🔄 Opening hours: For maximum compatibility, please select 802.11n/ac (or 802.11ax, if the router supports Wi-Fi 6).
• 📡 Transmission power: If the signal is weak, increase the power to 100% (may be set to default) 50–75%).

On routers Sagemcom These settings are located in the section Wi-Fi → Additional, on Sercomm - V Wireless → Advanced.

Flashable firmware (for advanced users): if your router supports alternative firmware like OpenWRT, you can significantly expand the functionality. However, this is risky—if you make a mistake, the device can become bricked.

7. Testing new settings and troubleshooting

After saving changes:

1. Connect to the new network from any device using the new name and password.
2. Check your internet speed (for example, on Speedtest.net).
3. Make sure that other devices (smartphones, TVs, printers) connect without errors.

Typical problems and their solutions:

• 🚫 Doesn't connect to Wi-Fi: Check that the password is entered correctly (case-sensitive!). Restart the router.
• 🌐 No internet access: Make sure that in the settings WAN the correct connection type is specified (usually PPPoE For Rostelecom).
• 🔄 The router constantly reboots: Reset to factory settings and set up again.

⚠️ Attention: If after changing the settings the Internet is lost on all devices, check if the parameters have been reset VLAN or PPPoE (they may be reset when updating the firmware). In this case, you will have to manually enter the data from the contract with Rostelecom.

8. Saving settings and backup

To avoid having to reconfigure your router after a failure, make a backup copy of your configuration:

1. In the control panel, find the section System tools / System Tools.
2. Select Backup / Backup Configuration.
3. Save the file to your computer (usually it is a file with the extension .cfg or .bin).

If you ever need to restore your settings, upload this file to the section Recovery / Restore Configuration.

Store the backup in a secure location (e.g., in the cloud or on a flash drive). Remember to update it after making changes to the router configuration.
