Modern internet surfing and working from home are impossible without a stable wireless connection, and for subscribers of the Belarusian provider Byfly, the main gateway often becomes a device Promsvyaz MT-PON-AT-4, which is technically an OEM version of the equipment ZTEDespite the visual differences in the logos, the underlying software and interface logic are identical, allowing you to use proven configuration methods to ensure maximum speed and security. Properly setting up a WiFi router involves more than just entering a password; it involves a series of steps to optimize the radio channel, select the frequency range, and install reliable encryption protocols.
Owners of this terminal often face the need to change the default network name or enhance security, especially if the device was installed by provider technicians several years ago and hasn't been updated since. It's important to understand that default settings, such as WPA2-PSK A simple password or a 2.4 GHz-only network may not provide adequate performance in multi-apartment buildings with dense neighboring networks. In this article, we'll take a detailed look at how to access your modem and adapt its work to modern requirements.
The configuration process may seem complicated at first, but following the steps step by step will give you complete control over your home network. We'll cover both basic security settings and advanced settings, including frequency band separation and device filtering. Being prepared to experiment with the settings will allow you to get the most out of your plan and equipment. ZTE.
Preparing for setup and logging into the web interface
Before making any configuration changes, you must ensure a stable connection between your control device (computer or smartphone) and the router itself. The most reliable way to perform the initial setup is via a wired connection using LAN cable, as this will prevent connection interruptions while the new WiFi settings are applied. If this isn't possible, make sure you're connected to your device's current wireless network, even if it's slow.
To access the control panel, open any browser and enter the gateway IP address in the address bar. By default, the equipment Promsvyaz And ZTE the address is used 192.168.1.1In the authorization window that opens, you will need to enter your username and password. Most often, the login information is located on the bottom sticker of the device: login admin and a unique password or combination admin / admin.
⚠️ Note: If the default data doesn't work, the password may have been changed previously. In this case, you'll need to perform a full reset of the modem to factory settings, which will delete all current configurations, including the PPPoE settings from your provider.
After successful authorization, you'll be taken to the main status page, which displays the fiber optic line (PON) status, device temperature, and the number of connected clients. The interface may be in Russian or English, depending on the firmware version installed by your provider. For more detailed configuration, you'll need to access the advanced menu, often hidden behind the "More Settings" or "Advanced" button.
Basic WiFi network setup
The main section responsible for radio broadcasting is usually located in the menu Network -> WLAN -> BasicThis is where you set your network name (SSID), which will be displayed in the list of available connections on phones and laptops. It's recommended to give the network a unique name that doesn't contain personal information, so neighbors can't easily identify the access point's owner.
The operating mode and channel width are critical parameters. For the 2.4 GHz band, the optimal channel width is 20 MHz in multi-apartment buildings, as this reduces interference from microwaves and Bluetooth devices. If you live in a private home or far from other networks, you can install 40 MHz to increase throughput, but stability may decrease.
- 📡 SSID: The network name visible to all surrounding devices.
- 🔒 Security Mode: Encryption protocol, select only WPA2-PSK or WPA3.
- 📶 Channel: Radio channel, it is better to use auto-selection or free 1, 6, 11.
Don't forget to save your changes by clicking the button Apply or SaveAfter this, the router may briefly reboot the wireless module, and the connection will be lost. You'll need to re-find the network with the new name in the list of available WiFi networks and enter the new password.
Setting up security and choosing a password
Home network security starts with choosing the right encryption algorithm. In the interface ZTE/Promsvyaz In the Security section you need to set the mode WPA2-PSK (AES). Older protocols, such as WEP or WPA (TKIP), are considered obsolete and easily cracked, and their use can significantly reduce connection speed.
Your passphrase should be complex but memorable. Use a combination of uppercase and lowercase letters, numbers, and special characters. The password should be at least 12 characters long. Avoid using simple sequences like "12345678" or birthdays, which are easy to brute-force.
| Parameter | Recommended value | Description |
|---|---|---|
| SSID Broadcast | Enable | Hiding the network is not recommended for home use. |
| WPA Algorithm | AES | The most secure encryption standard |
| Group Key Update | 3600 sec | Encryption key change interval |
| Max Clients | 32 | Maximum number of connected devices |
Also in this section, the function is often available WPS (WiFi Protected Setup). Despite the convenience of connecting with a single click, this technology has known vulnerabilities. Information security experts recommend completely disabling WPS in your router settings unless you regularly use it to connect printers or cameras.
⚠️ Note: The interface and available options may vary depending on the firmware version provided by Byfly. If you don't see the described options, check the latest documentation on the support portal or contact technical support.
Works with 2.4 GHz and 5 GHz bands
Modem Promsvyaz MT-PON-AT-4 It's a dual-band device, meaning it supports both the classic 2.4 GHz frequency range and the more modern 5 GHz. The 2.4 GHz range has better wall penetration, but is heavily congested in residential areas. The 5 GHz range offers higher speeds, but is less able to penetrate obstacles and has a shorter range.
In the WLAN settings you can see the option to configure separately for 2.4G And 5GMany users prefer to give these networks different names (for example, Home_WiFi And Home_WiFi_5G) to manually select which network a particular device connects to. For smartphones and laptops located near the router, 5 GHz is ideal, while 2.4 GHz is ideal for smart light bulbs and vacuum cleaners.
Why is 5GHz faster?
The 5 GHz band has more non-overlapping channels and is less susceptible to interference from household appliances, allowing for faster and more stable data transmission, especially in multi-family buildings.
There is also a function Band Steering (or Smart Connect), which combines both bands under a single network name. The router automatically decides which frequency to connect to based on signal strength and channel congestion. However, on budget ZTE models, this feature sometimes malfunctions, hopping devices between bands, which can cause brief connection interruptions.
MAC address filtering and guest networking
For greater control over your network, you can use MAC address filtering. This method allows you to create a "whitelist" of devices allowed to connect, or, conversely, a "blacklist" for uninvited guests. The setting is located in the section WLAN -> MAC FilterTo block access to a specific device, you need to know its unique MAC address and add it to the block list.
Guest Network is a useful feature for those who frequently have visitors. It creates a separate access point with its own password, isolated from your main local network. This means guests can use the internet but won't have access to your shared folders, printers, or computer files.
- 🛡️ Whitelist: Access is allowed only to selected devices.
- 🚫 Blacklist: Access is denied to selected devices, others are allowed.
- 🕸️ Guest Zone: Complete isolation of guests from home infrastructure.
Enabling a guest network doesn't affect the speed of the main channel, but it does consume the router's CPU resources. If you have many IoT devices connected (smart plugs, cameras), creating a separate network segment for them is also a smart move from a security perspective.

Troubleshooting and Signal Optimization
Even after proper setup, issues with connection speed or stability may still arise. First, check the indicators on the modem. PromsvyazIf the red LOS indicator is lit, the problem is on the ISP's end (cable break). If the LAN indicator is flashing, active data transfer is in progress.
To optimize the signal, it's important to position the router correctly. Don't place it in a recess, behind a TV, or on the floor. The ideal location is in the center of the apartment, 1.5–2 meters above the ground. Antennas (if external) should be pointed vertically upward. It's also worth checking that the device isn't overheating, as thermal throttling can reduce the performance of the WiFi module.
If speed remains low, try changing the channel manually. Automatic channel selection isn't always effective. Use channels 1, 6, or 11 for 2.4 GHz, as they don't overlap. For 5 GHz, choose channels in the 36-48 or 149-165 range, avoiding DFS channels if you notice instability.
Frequently Asked Questions (FAQ)
How do I reset my Promsvyaz/Byfly router to factory settings?
On the back or bottom of the device, look for a small hole marked Reset or RSTTake a paperclip or a thin needle, press the button inside the hole, and hold it for about 10-15 seconds until all the lights flash simultaneously. After this, the router will reboot to factory settings.
What should I do if I forgot my WiFi or admin password?
If you've forgotten your WiFi password, you can find it in your router settings if you're connected via cable. If you've forgotten your web interface password (192.168.1.1) and standard admin It doesn't work, only a full reset and subsequent re-configuration of the Internet will help.
Can I use my own router instead of Promsvyaz?
Yes, you can connect your powerful router to the Byfly fiber optic terminal. To do this, the terminal must be set to Bridge mode, and your router must be configured for a PPPoE connection. However, for interactive TV (Zala) to work, additional IGMP Proxy or VLAN settings may be required.
Why does the router get hot and turn off?
Heating up to 50-60 degrees Celsius is normal for such devices. If it shuts down spontaneously, check the power supply—it may be faulty. Also, make sure the router is on a solid surface and nothing is blocking the ventilation holes.
