How to change your Wi-Fi router password via a computer: a guide for Beltelecom subscribers

Changing your home Wi-Fi password is a basic step to securing your personal network, often required after purchasing a new device or if unauthorized access is suspected. ByFly (Beltelecom) subscribers must follow a series of specific steps, as the default factory combinations are often the same across thousands of devices and are easily guessed by attackers. The process of updating the access key requires connecting to the router's web interface via a browser, which can be done over either a wired or wireless connection.

Equipment owners from ByFly are faced with a variety of router models, among which the most common brands are devices ZTE, Huawei And Eltex. Despite the external differences in the cases and logos, the control panel access principles are similar, although the settings paths may vary slightly. Proper setup wireless network security Protect your banking data, correspondence, and browsing history from prying eyes.

Before you begin changing settings, make sure your computer or laptop is connected to the router. This can be done in two ways: Wi-Fi connection or through LAN cable, which is usually included with the device. A wired connection is preferable, as it ensures a stable connection while making configuration changes, eliminating the risk of connection interruption at a critical moment.

Preparing to change router settings

The first step is to physically or logically connect your computer to the router's network. If you're changing your password because you've forgotten the old one and can't connect via Wi-Fi, your only option is to use Ethernet cable. Plug one end of the cable into the yellow LAN port on the router and the other end into the network port on your PC or laptop.

You will also need to know the address to access the control panel. For most Beltelecom devices, the default 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, next to the serial number and factory administrator password.

⚠️ Important: If you change settings via Wi-Fi, please be aware that immediately after changing the password, your device will lose connection to the router. You will need to reconnect to the network using the new access key.

Open any modern browser: Google Chrome, Yandex Browser, Mozilla Firefox or OperaEnter your router's IP address in the address bar (the place where you type the website address, not the search bar). After pressing Enter, the system will ask for your username and password to access the settings.

Authorization in the router web interface

A router's security system requires authentication to prevent unauthorized access to your network configuration. The default login credentials for the control panel are often found on the same sticker as the device's address. For equipment ZTE And Huawei, provided by the provider, the login link is often used admin and password admin, or user And user.

However, in modern models, especially in the line EltexThe password for entering settings can be unique for each device and also located on a sticker under the case. If the standard combinations don't work and the individual password is lost, the only solution is a full password. reset settings to factory settings. To do this, hold down the button Reset on the back panel of the router for 10-15 seconds with the power on.

After successfully entering the data, you will be taken to the main page of the control panel. Here you may need to select an operating mode (for example, Route), if the router is in bridge mode. To change the Wi-Fi password, we don't need to delve into the technical settings; simply find the section responsible for the wireless network.

Router model Standard IP Default login Default password
ZTE F660 / F670 192.168.1.1 admin admin (or from the sticker)
Huawei HG8245H 192.168.100.1 telecomadmin admintelecom
Eltex NTU-2 192.168.1.1 admin admin (or from the sticker)
Sagemcom 192.168.1.1 admin admin

Interfaces from different manufacturers may look different, but the logic remains the same. If you see a menu in English, look for the words Wireless, WLAN or Wi-Fi SettingsIn Russian versions, this is usually the "Wireless Network" or "WLAN Settings" section.

Instructions for ZTE routers (F660, F670)

Equipment brand ZTE is one of the most popular among Beltelecom subscribers. After logging in to the system at 192.168.1.1 you need to go to the top menu and select the tab Network (Network). In the list that opens on the left, find the item WLAN and subparagraph Security (Safety).

The center of the screen will display your wireless network security settings. Find the field WPA Passphrase or Pre-Shared KeyThis field contains your current password. Erase the old characters and enter a new combination. It is recommended to use mixed register letters and numbers for maximum protection.

☑️ Checking ZTE settings

Completed: 0 / 1

After entering the new key, be sure to press the button Submit or Apply at the bottom of the page, otherwise the changes will not be saved. The router may warn you that all connected devices will be disconnected—this is a normal system reaction to changing the encryption key.

In some ZTE firmware versions the path may be slightly different: Network -> WLAN -> SSID SettingHere you can change not only the password, but also the network name (SSID), which is displayed in the list of available connections on phones and laptops.

Setting up Wi-Fi on Huawei devices

Routers Huawei, such as the popular HG8245H or HG8145V5 models, have their own unique interface. After authorization (login is often required) telecomadmin and password admintelecom for full access, or data from the sticker for basic) go to the tab WLAN.

In the menu on the left, select WLAN Basic Configuration or immediately WLAN Security ConfigurationUnlike ZTE, the settings here can be broken down into several sub-items. You need to find the field WPA/WAPI Pre-Shared KeyEnter your desired password in the appropriate text field.

⚠️ Note: Firmware interfaces may be updated by your provider. If you don't see the described options, check the current menu structure in the technical section on your provider's official website or in your personal account.

Pay attention to the parameter Encryption mode (Encryption Mode) For high speed and security, select WPA2-PSK and the algorithm AES. Outdated encryption methods such as TKIP or WEP, it is not recommended to use them, as they are easily hacked and can limit the Internet speed.

Complete the procedure by clicking the button ApplyThe router will apply the new settings and the wireless module will restart. Your device will lose connection, and the connection status in the list of available networks will change to "Login required" or "Connection error," indicating the password has been successfully changed.

Changing the password on Eltex terminals

Optical terminals Eltex (for example, NTU-2 or W2) often have a more streamlined and laconic interface. By logging in at 192.168.1.1, find the tab in the top horizontal menu Service or Wireless. Then follow the path WLAN -> Security.

Here you will see a list of SSIDs (network names) if there are multiple (for example, Guest and Home). Select the primary network, usually labeled as SSID1In the field Pre-Shared Key Enter a new security combination. The password must be between 8 and 63 characters long.

What should I do if the Save button is grayed out?

Sometimes the password entry field remains grayed out until a security type is selected. Ensure WPA2-PSK is selected in the "Security Mode" drop-down list before the password entry field becomes editable.

An important feature for Eltex owners is the ability to create a guest network. You can set a separate password for guests to prevent access to the main network containing smart devices and personal files. This can be done in the adjacent tabs of the WLAN section.

Don't forget to press the button Save/ApplyIn Eltex devices, changes are often applied instantly, without a full reboot of the device; however, the wireless module will briefly shut down to apply the new encryption keys.

Requirements for creating a strong password

The security of your network directly depends on the complexity of the password you choose. Simple combinations like 12345678, password or a phone number can be hacked using special programs in a matter of seconds. An ideal Wi-Fi password should contain at least 12 characters, including uppercase and lowercase letters, numbers, and special characters.

Use mnemonic rules to remember complex keys. For example, take the phrase "I like to drink coffee at 7 a.m." and transform it into a password: Ylpkv7u!Such a password is extremely difficult to brute-force, but easy for the owner to remember.

Avoid using personal information that might be known to neighbors or friends, such as birth dates, apartment numbers, or pet names. Attackers often use social engineering to brute-force access keys to secure networks.

  • 🔒 Use at least 10-12 characters for maximum protection against guessing.
  • 🔢 Combine numbers, uppercase and lowercase letters, and special characters (!, ?, #, @).
  • 🚫 Avoid using dictionary words and key sequences (qwerty, 123456).
  • 🔄 Change your password at least once every six months if third-party devices connect to your network.

Possible problems and their solutions

During the setup process, users may encounter various difficulties. It often happens that after entering a new password and clicking the save button, the page simply reloads, and the old password remains. This may indicate that the browser is using cached version pages or page scripts are blocked.

Try opening your router settings in Incognito mode or a different browser. Also, make sure your computer is set to automatically obtain an IP address. If you previously assigned a static IP manually, this may conflict with your router settings after a reset or network configuration change.

⚠️ Important: If after changing the password, the router stops distributing internet or the PON/LOS indicator flashes red, you may have accidentally changed your ISP settings (VLAN or PPPoE). In this case, it's best to contact technical support.

Another common problem is that the device "forgets" its settings after being turned off. This indicates a faulty internal battery or damaged flash memory. In this case, the device needs to be replaced, as it is physically unable to save the configuration.

Frequently Asked Questions (FAQ)

What should I do if I forgot my new password immediately after changing it?

If you didn't have time to connect devices with the new password and forgot it, you'll need to log in to the router's web interface again (if you're connected via cable, you can log in without the Wi-Fi password) and view the current key in the wireless network settings. If you've completely lost access, the only solution is to reset the router using the Reset button.

Is it possible to change the password on a Beltelecom router from a phone?
