Changing your home network password is the first step you need to take to ensure the basic security of your digital space. Many ISP users ByFly (brand Beltelecom) leave their network at factory settings, leaving it vulnerable to unauthorized traffic and data theft. The process of updating the access key doesn't require extensive networking knowledge and only takes a few minutes if you know the correct procedure.
In this article, we will examine detailed steps for all current terminal models issued by the operator, including equipment using fiber-optic technology. GPONYou'll learn not just how to change numbers, but also how to choose strong encryption algorithms to prevent your neighbors from using your internet for free. This will also solve the problem of sudden speed drops that often occur when the channel is overloaded with multiple connected devices.
Before you begin, make sure your device (computer or smartphone) is connected to the router either via cable or your current Wi-Fi network. If you plan to change settings from your phone, it's best to have a hard copy or note with the new password ready, as the connection will be lost after applying the settings. Restoring access This will only be possible after entering new data.
Preparing to change security settings
Before entering the control panel, you need to access the router interface itself. To do this, you'll need to know the device's IP address, which is the default for most models. ByFly makes up 192.168.1.1 or 192.168.100.1Enter this address in the address bar of any browser (Chrome, Firefox, Safari) and press Enter. If the page doesn't load, check your adapter's network settings—they should be set to obtain an IP automatically (DHCP).
The system will request authorization. The standard login and password are often indicated on a sticker on the bottom of the device, but in most cases, combinations are used for the administrative panel. admin / admin or user / user. For equipment Huawei And ZTE Credentials may vary depending on the year of manufacture and the specific firmware version. If the default pairs don't work, the password may have been changed previously, and a factory reset will be required.
⚠️ Attention: If you're changing settings via Wi-Fi, remember that changing the password will cause your device to lose connection to the router. You'll need to manually reconnect to the network and enter the new key. For critical changes, it's recommended to use a cable connection.
Ethernet.
Web configuration interfaces may look different, but their logic is the same. Try not to close the browser tab until the process is complete. Modern routers GPON have a session timeout, so if you spend too much time reading the theoretical part, the system may log you out for security reasons, and you will have to start the procedure again.
Login to the router's web interface
After successful authorization, you'll be taken to the main device status page. This displays the uptime, connection type, and channel load. We're interested in the section responsible for the wireless network. Depending on the terminal model, this section may be called WLAN, Wireless, Wi-Fi or Wireless networkIn the navigation menu, this is usually one of the top or side tabs.
Within the wireless network section, you need to find the subsection related to security. It is often labeled as WLAN Security, Security Settings or Security settingsThis is where you'll find the fields for entering a new password (Pre-shared Key) and selecting the encryption type. Don't confuse this section with the MAC address filtering settings, which allow or deny access to specific devices.
Interfaces from different manufacturers have their own navigation features. For example, in routers Huawei the structure is often used WLAN -> WLAN Security Configuration. In devices ZTE the path may look like this Network -> WLAN -> SecurityPlease read the item names carefully, as the interface translation into Russian is sometimes incorrect or automatic.
What should I do if I forgot my admin password?
If you've changed your router's password and forgotten it, the only solution is to perform a hard reset. Find the small hole marked "Reset" on the router's case and press it with a paperclip for 10-15 seconds while the router is powered on. The router will reset to factory settings, and the password will be the same as the one on the sticker.
Step-by-step instructions for Huawei routers
Equipment Huawei is one of the most common on the web ByFlyTo change the password on series models HG8245 or EG8145 you need to go to the tab WLAN in the top menu. Then select the sub-item WLAN Security ConfigurationIn the window that opens, find the field WPA/WPA2 pre-shared keyThis is where the new password is entered.
An important point is the choice of encryption mode. In the field Authentication mode (Authentication Mode) Select a value WPA2-PSK or WPA/WPA2-PSKThis will ensure maximum compatibility with all modern devices and a high level of protection. Outdated protocols like WEP or WPA (without the number 2) is not recommended for use, as they can be easily hacked with special utilities in a matter of minutes.
After entering a new password and selecting the encryption type, be sure to click the button Apply or Save (Apply/Save) at the bottom of the page. Without this step, all changes will remain only in the browser's memory and will not be written to the router's configuration. The device may reboot the wireless module, which will take approximately 10-20 seconds.
☑️ Check Huawei settings
If you have a dual-band router that supports 5 GHz, the settings for 2.4 GHz and 5 GHz frequencies may be in different tabs or can be switched via a drop-down list. SSID IndexBe sure to change the password on both frequencies if they use the same network name, or set them up separately for better connection management.
Setting up security on ZTE devices
Routers ZTE (for example, models F660, F670) have their own interface, which is often called "green" due to the color scheme. To change the password, go to the menu Network, then select WLAN and further SecurityIn some firmware versions the path may be WLAN -> Security -> WPA Pre-Shared Key.
In the field WPA Passphrase Enter a complex password of your choosing. The system may require confirmation of the password in the second field if this option is enabled. Make sure encryption mode is enabled. WPA2-PSKIn older firmware versions ZTE Sometimes the default mode is mixed, which can cause connection problems with some smart devices (IoT), so it is better to fix it strictly WPA2.
After making changes, click the button Submit or Save Settings. Interface ZTE often takes longer to apply settings compared to HuaweiAt this point, the Wi-Fi indicators on the router may flash rapidly or go off briefly. This is normal behavior and indicates that the radio module is restarting.
⚠️ Attention: In some firmware versions ZTE For ByFly There's a bug where the page freezes after saving the settings. Don't panic and don't immediately reboot the router with the power button. Wait 1-2 minutes, then try refreshing the browser page or connecting to Wi-Fi with the new password.
Changing the password on Eltex terminals
Operator ByFly actively implements equipment Eltex (models NTU-4W, EGW-101). The interface of these devices is more formal and technical. To change the password, go to the menu Wi-Fi -> Basic (or General). Here you will see a list of SSIDs (network names). Select the one you want to change (usually it is SSID1).
Go to the tab Security (Security). In the field WPA key (WPA Key) Enter a new combination of characters. Feature Eltex is a flexible configuration option. You can also disable the function here. WPS, which is highly recommended for increased security, as this authentication method has known vulnerabilities.
Don't forget to press the button Save at the bottom of the page. Unlike other vendors, Eltex A reboot of the entire device may be required for some settings to take effect, although password changes are usually applied immediately. Check the list of connected clients after changing the password to ensure that the unauthorized users have been disconnected.
Selecting the encryption type and network name
Network security depends not only on the password's complexity, but also on the encryption protocol chosen. In your Wi-Fi settings, you'll see abbreviations WEP, WPA, WPA2 And WPA3WEP is an outdated standard that can be cracked in seconds; its use is unacceptable. WPA (TKIP) is also considered obsolete and hinders the speed of modern devices.
The optimal choice today is WPA2-PSK (AES)This standard provides reliable encryption and is supported by the vast majority of gadgets. If your router and all devices support the new standard, WPA3, you can select the mode WPA2/WPA3 Mixed or pure WPA3, but this may cause problems with older laptops or smart plugs.
This section also changes the network name (SSID). It's recommended to give the network a unique name that doesn't contain personal information (such as addresses or last names). This will make it more difficult for attackers to use databases to find vulnerable networks in your area. Changing the network name will also force all your devices to request a password again.
| Parameter | Recommended value | Description | Security |
|---|---|---|---|
| Authentication Mode | WPA2-PSK | Modern standard of protection | High |
| Encryption | AES | Data encryption algorithm | High |
| WPS | Disabled | Simplified connection | Low (vulnerable) |
| SSID Broadcast | Enabled | Network visibility | Average |
Common mistakes and troubleshooting
When setting up a network on your own, users often encounter common problems. One of the most common is that the device won't connect to the network after changing the password, displaying an "Incorrect Password" error or endlessly attempting to obtain an IP address. In this case, find your network in the list of saved networks on your smartphone or laptop, select "Forget Network," and re-enter the password from scratch.
Another issue is character incompatibility. Some older devices may not work correctly with passwords containing Cyrillic (Russian letters) or special characters such as spaces, quotation marks, or question marks. To avoid problems connecting guests or smart devices, use only Latin letters (A-Z, a-z) and numbers (0-9).
If the internet stops working on all devices after changing your password, you may have accidentally changed other settings in adjacent tabs, such as the WAN connection type or VLAN ID. In this case, the only solution is to reset the settings using the reset button. Reset on the case and reconfigure from scratch, or call the provider's technical support to restore the configuration remotely.
FAQ: Frequently Asked Questions
How often should I change my Wi-Fi password?
Cybersecurity experts recommend changing your Wi-Fi password every 3-6 months, especially if you've had many guests or suspect your neighbors may have learned your key. However, if you use a very complex, unique password (15+ characters) and disable WPS, the need for frequent changes is reduced.
Is it possible to change the Wi-Fi password from your phone?
Yes, this is possible. You need to connect to the router, open a browser on your phone, and enter the router's IP address (usually 192.168.1.1). The interface adapts to the mobile screen, and you can change the settings just like on a computer.
What should I do if my ByFly router doesn't accept the new password?
Check your password length. The minimum length is usually 8 characters. Also, make sure you're not using prohibited characters or spaces. If the issue persists, try refreshing the router settings page (F5) and entering your information again.
Does changing your password affect your internet speed?
Changing your password itself doesn't affect your speed. However, if you've previously had a lot of third-party devices connecting to your network and hogging your bandwidth, changing your password and disconnecting them will significantly improve your internet speed.
