Modern internet access is hard to imagine without a wireless connection, which allows you to connect smartphones, laptops, and smart devices without unnecessary wires. ByFly subscribers often encounter a situation where, after installing equipment or resetting settings, the internet only works via a cable, and mobile devices cannot see the network. Activating the radio module is the first step towards comfortable use of home gadgets.
The setup process may seem complicated to the untrained user, especially given the differences in the interfaces of different terminal models. However, understanding the basic operating principles web interface Knowing the standard login addresses, you can manage your connection settings yourself. In this article, we'll detail the steps for ZTE and Huawei equipment, which are most commonly installed by operators.
It's worth noting that the physical buttons on the device's body can temporarily disable the signal, so before starting software configuration, you must ensure that the hardware is in good working order. Most modern Beltelecom models have Wi-Fi enabled by default out of the box, but its settings often require manual adjustment to ensure security. If you experience a complete lack of signal, you may need to perform a factory reset via the recessed Reset button.
Preparing for setup and entering the interface
Before making any configuration changes, ensure a stable connection between your computer and the router. A wired connection via a LAN port is the most reliable, as it guarantees access to the control panel even if the wireless signal is compromised. Connect the network cable to the yellow port on the back of the modem and the corresponding port on your PC's network card.
Once physically connected, open any browser and enter the device's IP address in the address bar. For ByFly equipment, the standard address is 192.168.1.1 or domain name 192.168.0.1In the authorization window that opens, you will need to enter your login and password. By default, the sticker on the bottom of the case often indicates admin/admin or individual data unique to each instance.
If the default credentials don't work, they may have been changed previously. In this case, you'll need to perform a factory reset by holding the Reset button for 10-15 seconds. After the reboot, access to the interface will be restored to factory settings, allowing you to start setup from scratch.
⚠️ Attention: When you reset your settings using the Reset button, you delete not only your Wi-Fi password but also all PPPoE connection settings. Make sure you have saved the internet login and password provided by your provider, otherwise the network will not work after the reset.
Activating Wi-Fi on ZTE (ZXHN) routers
ZTE devices, particularly the ZXHN F660, F670, and H108N series, have a unique menu structure that can be confusing for beginners. After successfully logging into the system, you need to go to the Settings tab. Network (Network) in the top menu. Next, select the section WLAN, where all wireless connection parameters are located.
In the menu that opens, find the subsection Basic or SecurityThis is where the main switch that activates the radio module is located. Look for the item Enable WLAN or SSID Enable and check the box next to it. Without this checkbox enabled, the device will not broadcast a signal, even if all other parameters are set correctly.
Below are the security settings. Be sure to select the encryption type. WPA2-PSK or WPA3, since the outdated WEP standard is easy to crack. In the field Pre-Shared Key Enter a complex password consisting of letters and numbers, at least 8 characters long. Save the changes by clicking the button Submit or Apply.
☑️ Checking ZTE settings
It's important to understand that some ZTE models allow you to set up multiple guest networks. If you don't plan to use them, it's best to disable them. SSID2 And SSID3to avoid cluttering the airwaves and reducing overall network performance. This is especially important in apartment buildings with a high density of neighboring access points.
Setting up a wireless network on Huawei (HG series)
Huawei modems, such as the HG8245H, HG8245Q, or the newer HG8145V5, have a more user-friendly interface, often even available in Russian. After logging in via your browser, go to the menu. WLAN at the top of the screen. In the left column, select WLAN Basic Configuration.
Here you will see a list of frequency bands: 2.4G and 5G. To enable the network, you need to check the box. Enable WLANIf your router is dual-band, you can activate both bands simultaneously by assigning them different names (SSIDs) so devices can select the most suitable frequency.
Go to the next section WLAN Security Configuration to set a password. In the field WPA pre-shared key Enter your new access key. Make sure that the field Authentication Mode value selected WPA2-PSKAfter entering the data, be sure to click the button Apply at the bottom of the page, otherwise the settings will not be saved.
What should I do if the interface is in Chinese?
If you see Chinese characters instead of Russian or English, try changing the ending of the address in your browser's address bar. Often, adding "?language=en" or looking for a drop-down list with a flag or the abbreviation "LANG" in the menu (usually in the upper right corner) is enough. If this doesn't help, use the browser's translator (right-click -> Translate to Russian), but be careful when selecting menu items.
Pay special attention to the function WPSOn Huawei routers, it is often enabled by default, which creates a vulnerability. In the section WLAN WPS Configuration It is recommended to uncheck the box Enable WPSto prevent unauthorized connections to your network by brute-forcing your PIN.
Differences between 2.4 GHz and 5 GHz frequencies
Modern Beltelecom modems often support dual band operation. Understanding the differences between them will help you optimize internet speed for different tasks. 2.4 GHz It has a longer range and penetrates walls better, but it is heavily congested with signals from microwaves, Bluetooth devices, and neighboring routers.
Range 5 GHz Provides significantly higher data transfer rates and is virtually interference-free in apartment buildings. However, its range is shorter and it has poorer penetration through solid concrete floors. For online gaming, 4K video, and video conferencing, 5 GHz is preferable.
The table below provides a comparison of characteristics for ease of selection:
| Characteristic | 2.4 GHz | 5 GHz |
|---|---|---|
| Range of action | High (up to 50 meters) | Medium (up to 20 meters) |
| Permeability of walls | Good | Bad |
| Maximum speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Interference level | High | Short |
| Device support | All devices | Only modern gadgets |
If you live in a private home or on the top floors of a new building where there are few neighboring networks, you can use only 5 GHz for maximum speed. In older homes with thick walls, 2.4 GHz is often the only viable option.
Changing the network name and security password
The factory network name (SSID) usually contains the router model name and a set of numbers, which is not only inconvenient but also reveals information about potential vulnerabilities of a specific equipment model. You can change the name in the same sections WLAN Basic, where you included the module itself. The field is called SSID Name.
When choosing a name, avoid using personal information such as your last name, apartment number, or address. This could aid attackers in social engineering. It's better to use neutral names or abstract words that don't reveal anything about the owner.
Password protection is critical. Default passwords printed on stickers are often shared across multiple devices. When changing your password, use a combination of uppercase and lowercase letters, numbers, and special characters. Passwords should be at least 12 characters long to ensure reliable protection against brute-force attacks.
⚠️ Attention: After changing the password, all your devices (phones, tablets, TVs) will lose connection to the router. You will need to re-enter the new password on each device. We recommend changing the settings from a device that is definitely connected via cable to avoid losing access during the process.
Solution: Why Wi-Fi isn't working
Even after proper setup, users may encounter issues. If devices don't see the network, check whether the module is disabled using the physical button on the device. Some ZTE and Huawei models have a button. WLAN or Wi-Fi, a short press of which turns wireless transmission on or off.
Another common cause is a full list of connected clients or a router software glitch. In this case, a simple reboot helps: unplug the device for 10-15 seconds and then plug it back in. This clears the RAM and restarts services.
If the problem persists, check your channel settings. In automatic mode, the router may select a congested channel. In the WLAN settings, find the option Channel and try switching it from Auto to a specific number (for example, 1, 6 or 11 for 2.4 GHz), after first analyzing the airtime load of special applications on the smartphone.
Frequently Asked Questions (FAQ)
How do I reset my Wi-Fi password if I forgot it?
If you can't remember your password, the only solution is to reset the router to factory settings using the Reset button. Afterwards, a default password will be located on the back of the device (on a sticker) that you can use to log in. You must then change the password in the settings.
Is it possible to turn on Wi-Fi via an app on my phone?
Official Beltelecom apps (such as "My ByFly" or "Dom.ru") typically only allow you to check your balance and tariffs. For detailed router configuration (enabling/disabling modules, changing channels), you need to use the web interface via a browser and IP address.
Why is Wi-Fi speed slower than cable?
Wireless connections always incur signal encoding overhead and are susceptible to interference. Furthermore, speed is limited by the capabilities of the router's antenna and your phone's receiver. For maximum speed, use a cable or the 5 GHz band.
Is it safe to use WPS for guest connections?
No, WPS technology is considered outdated and vulnerable. Attackers can brute-force the PIN and gain access to your network. It's better to create a guest network with a separate password in your router settings.
