Changing the default wireless network access key is the first step a new ByFly subscriber must take after installing their equipment. Factory-set passwords, printed on a sticker, are often publicly available, and any neighbor who knows your device's model could theoretically attempt to access the network. Home Internet Security directly depends on the complexity and uniqueness of the combination of characters that you set.
Routers of the brand ZTEThe devices provided by your telecom operator have a user-friendly web interface, allowing you to manage your network without any specialized knowledge. However, the settings menu may vary depending on the firmware version and the specific device model, whether it's the F660, F670, or newer series. In this guide, we'll cover the general steps to help you protect your personal traffic from prying eyes.
Ignoring this step can not only result in a decrease in your connection speed due to the load from other devices, but also a potential leak of personal data. The standard WPA/WPA2 password on the router sticker is the same for thousands of devices from the same batch, making it extremely vulnerable to brute force. Therefore, regularly changing your access key is a basic rule of digital hygiene.
Preparing to change security settings
Before you begin changing your router's configuration, you need to ensure a stable connection between your control device and the router itself. It's best to perform these steps from a computer or laptop connected via LAN cable, because during the process of changing the password, the wireless connection will be broken and you will lose access to the setup interface.
If using a cable isn't possible, make sure you're connected to the Wi-Fi network you plan to change and have an alternative connection method (such as mobile data on your smartphone) in case the settings get lost. You'll also need to know the default control panel login address for the equipment. ByFly is most often standard.
☑️ Ready to configure your router
It's important to have the sticker on the bottom of the device handy. It contains the login and password for logging into the administration system. This information is different from the Wi-Fi key, although in some configurations they may be the same. Without authorization, you won't be able to make changes to the wireless network settings.
Logging into the ZTE router web interface
The authorization process begins with launching any modern web browser. Enter the router's IP address in the address bar. For most models, ZTE, used by the provider, this 192.168.1.1 or 192.168.0.1If the address was previously changed, you can check it through the computer's network adapter settings in the "Default gateway" column.
After navigating to the address, the system will request your credentials. Beltelecom devices often use a login and password combination. admin / admin or the information found on the same sticker as your Wi-Fi password (sometimes labeled User/Password). Enter it in the appropriate fields on the login form.
⚠️ Attention: The router interface can be updated remotely by the provider. If the default logins don't work, the password may have been changed by you or the technician during installation. In this case, you'll need to perform a full reset using the Reset button on the back of the device.
A successful login will open the main control panel (Dashboard), which displays the connection status, device uptime, and current channel load. From here, we'll navigate to the sections related to wireless networks.
Navigating the WLAN settings menu
Interfaces of different models ZTE may have different menu structures, but the logic remains the same. You need to find the tab responsible for the wireless network. It's usually called Network → WLAN or simply WLAN in the top or side menu.
Inside the WLAN section, look for the subsection Security (Security) or SSID SettingsThis is where the fields for changing the network name (SSID) and encryption key are located. In some Beltelecom firmware versions, these settings may be located in a separate tab. Local Network → WLAN Security.
Pay attention to the number of available networks. Modern routers often support two bands: 2.4 GHz and 5 GHz. A password is set separately for each band, although for user convenience, they are often set to the same value. Make sure you're in the correct tab when changing settings.
What if the menu is in English?
If the router interface is entirely in English and you can't find the items you need, use the translator in your browser (right-click -> Translate to Russian) or use keywords like: Security, Pre-Shared Key, SSID.
It's important not to confuse the Guest Network settings with the main network. The Guest Network is designed for temporary access by visitors and often has limited access to local resources. Change the password for the main network in the section where your current network name (SSID) is listed.
Selecting an encryption type and creating a strong password
In the Security Settings section you will see a field Authentication Type or Security ModeThis is the most important parameter that determines how difficult it is to hack your network. Never select modes Open (open network) or legacy standards WEP And WPA/TKIP.
The optimal choice for modern devices is WPA2-PSK with encryption algorithm AES. If your device ZTE supports WPA3, it is recommended to use this standard, as it provides maximum protection against password brute-force attacks. However, it's worth keeping in mind that very old devices may not connect to a WPA3 network.
The password itself (the pre-shared key) must meet certain strength criteria. Simple sequences like "12345678" or a date of birth can be easily guessed in minutes using specialized programs. Use a combination of uppercase and lowercase letters, numbers, and special characters.
A password must be at least 12 characters long. The longer and more varied the characters, the higher the key's entropy, making it cryptographically strong. Write down your new password in a safe place immediately after creating it to avoid losing access.
Comparison of Wi-Fi security standards
Understanding the differences between security protocols will help you make an informed decision when setting up your router. ZTEBelow is a table showing the evolution of wireless network security and its vulnerabilities.
| Protocol | Year of implementation | Encryption algorithm | Security level |
|---|---|---|---|
| WEP | 1997 | RC4 | Critically low (hack in minutes) |
| WPA | 2003 | TKIP | Low (outdated, not recommended) |
| WPA2 | 2004 | AES (CCMP) | High (de facto standard) |
| WPA3 | 2018 | SAE / AES | Maximum (brute force protection) |
As the table shows, using WEP or regular WPA today is equivalent to not having a lock on your door. Routers ZTE Beltelecom's are typically configured to WPA2-PSK (AES) by default, which is a good balance between compatibility and security.
If you have older generation smart devices in your home (light bulbs, sockets) that stopped working after enabling WPA2/WPA3, try creating a separate guest network with less stringent settings just for them, while keeping your main network as secure as possible.
Saving settings and reconnecting devices
After entering a new password and selecting the encryption type, you must click the button Apply or Save (Apply/Save). At this point, the router will reboot the wireless network module. All devices connected to the Wi-Fi network will immediately lose their connection.
This is normal system behavior. You need to take your smartphone, tablet, or laptop, find your network name (SSID) in the list of available networks, and tap "Forget network" or "Delete profile" if the device is trying to connect with errors. Then enter a new password.
⚠️ Attention: If you configured the router via Wi-Fi, after clicking "Save," you'll lose access to the settings interface. To check the results and continue configuration, you'll need to reconnect to the network with the new password.
Check the internet connection on all your main devices. If any device isn't connecting, make sure you didn't make a typo when entering your password and that the letter case is correct (uppercase and lowercase letters are different).
Why don't devices see the network after changing settings?
Sometimes, after changing the channel or security standard, older devices may not see the network. Try rebooting the device (powering it off and then back on). If the problem persists, check whether the router has switched the frequency band or encryption type to one incompatible with the device.
Additional measures to protect your home network
Changing your password is just the first step. To strengthen your router's network security, ZTE It is recommended to disable this function. WPS (Wi-Fi Protected Setup). This technology allows you to connect to a network with a simple press of a button or by entering a PIN, but it contains critical vulnerabilities that allow hackers to recover the password.
It is also worth checking the list of connected clients in the section Status or User InterfaceIf you see unfamiliar devices there (for example, TVs or phones that you don't have in your apartment), this is a sign that the password has been compromised or guessed.
Update your router firmware regularly. Beltelecom occasionally sends out updates that patch security holes, but you can check for a new version manually in the "Updates" section. Maintenance → Upgrade.
What should I do if I forgot my new Wi-Fi password?
If you changed the password, wrote it down, but lost the record, and no device remembers this key, the only way out is to reset the router ZTE to factory settings. To do this, find the hole Reset On the back panel, press it with a paperclip and hold it for 10-15 seconds until the indicators blink. After this, the router will return to its out-of-the-box state, and the password will be the same as on the sticker. However, all other settings (PPPoE login and password from the provider) will also be reset, and the internet may stop working until you configure it again.
Is it possible to change the password through the app on the phone?
Official Beltelecom apps (such as "My ByFly" or "Dom.ru," if you use their infrastructure) often allow you to manage basic Wi-Fi settings, including changing your password, without logging into the router's web interface. Check your personal account functionality in the provider's app—this is the easiest way, as it doesn't require entering IP addresses.
Does changing your password affect your internet speed?
Changing your password itself doesn't affect speed. However, if you choose a modern encryption standard (WPA2/WPA3 AES) instead of an outdated one (WEP/TKIP), your speed may actually increase, as modern algorithms are less resource-intensive for the router's processor and don't throttle your speed like older protocols do.
Should I change my password regularly?
Cybersecurity experts recommend changing passwords for critical services every three to six months. For home Wi-Fi, it's sufficient to change the password if you suspect a hack or when purchasing a new router. The key is to initially set a complex combination that's virtually impossible to brute-force.
Can my neighbor steal my internet if I changed my password?
If you've set a strong password and enabled WPA2/WPA3 encryption, the chances of a neighbor "stealing" your internet connection are slim to none. Cracking modern encryption requires enormous computing power and time, which is impractical for gaining free internet access. The only risk is sharing your password with someone else.
