Beltelecom's Wi-Fi ByFly connection: complete instructions with photos and tips

Connecting to a Wi-Fi network ByFly from Beltelecom — is a standard procedure for subscribers of the Belarusian operator, but even this can raise questions for newcomers. Unlike mobile operators, where simply inserting a SIM card is enough, this requires proper router configuration, taking into account the specifics of the tariff plan, and sometimes even manual configuration. In this article, we'll cover every step—from connecting the cable to resolving authorization issues—to ensure your Wi-Fi works reliably on all devices.

Peculiarity ByFly that the operator uses technology PPPoE for authentication, rather than a dynamic IP, as with most CIS providers. This means that without a correctly entered login and password (which are included in the contract), the internet simply won't work. Furthermore, Beltelecom has its own nuances with VLANWe'll also cover tags and MAC address binding. If you've just connected to a service or moved to a new apartment with wired internet, this guide will help you avoid common mistakes.

Important: If you already had Internet from another provider and you just changed the operator ByFlyDon't rush to reset your router! It might be enough to just update your connection details. However, if your router is new, you'll have to set it up from scratch. We'll look at both scenarios below.

1. What equipment is needed for connection?

Before you begin setup, make sure you have everything you need. Without at least one of these components, you won't be able to connect:

• 📦 Router with PPPoE support - almost all modern models (for example, TP-Link Archer C6, ZTE ZXHN H267N or Huawei HG8245H) will work. If you have an older router (manufactured before 2015), check its compatibility on the Beltelecom website.
• 📄 Agreement with ByFly — the login is indicated there (usually in the format login@byfly.by) and a password to connect. Without them, it is impossible to log in to the network.
• 🔌 Network cable (Ethernet) — it comes with the router. If it's not included, any other one will do. CAT5e or higher.
• 💻 Computer, laptop or smartphone — for initial setup. It's more convenient to use the app on your phone. Tether (For iOS) or built-in browser.

If you rent a router from Beltelecom (for example, models Sercomm RV6699 or ZTE F670L), then the login and password for its admin panel are usually indicated on a sticker on the bottom of the device. Otherwise, use the default login details: admin, password - admin or password (depending on the model).

⚠️ Attention: If you are connecting in an apartment building where there was previously a different provider (for example, A1 or MTS), make sure that the entrance is not in use GPON equipment with MAC bindingIn this case, you may need to call ByFly support to activate the port.

Also check if there is a button on the router WPS — it can be useful for quickly connecting devices without entering a password (although this is less secure). If the button is present but the feature is disabled, it can be enabled in the wireless network settings.

2. Connecting the router to the ByFly network: physical installation

Let's start with the most basic thing—connecting the cables correctly. Errors at this stage will prevent the router from receiving a signal from the provider, rendering all subsequent settings useless.

1. Turn off the router Unplug the power cord (if it was plugged in). This is necessary to reset the current settings and avoid conflicts.
2. Connect the provider's cable (which comes from ONU terminal or directly from the switchboard in the entrance) to the port WAN (or Internet) on the router. It's usually highlighted in blue and separate from the other ports. LAN.
3. Connect the router to the computer using a patch cord (included) through any of the ports LAN (yellow). If you're setting it up from a smartphone, connect to the router's Wi-Fi network (its name and password are on the sticker).
4. Turn on the power router and wait until all the indicators light up. Pay special attention to the light WAN - it should blink or be constantly on (depending on the model).

If the indicator WAN does not light up, check:

• 🔌 Is the cable correctly inserted into the port (the latch should click).
• 🔄 Is the cable damaged? (Try replacing it with a known working one.)
• 🔧 Is the port disabled in the router settings (relevant if the device has already been used before).

On some routers (for example, Huawei HG8245H) port WAN can be combined with LAN1 and require manual mode switching in the admin panel. If you have such a model, check the section Network → WAN and select Internet for the first port.

3. Login to the router admin panel and perform basic setup

Now you need to go to the router's web interface to set up a connection to ByFlyThe login address, username, and password depend on the device model, but are most often:

To enter the control panel:

1. Open your browser (Chrome, Firefox, Edge) and enter the IP or domain name of your router in the address bar (see table above).
2. Enter your login and password (default or the ones you set earlier).
3. If the page doesn't open, check your connection to the router (cable or Wi-Fi) and try a different browser. You can also reset the router to factory settings using the button. Reset (hold it for 10 seconds).

After successfully logging in, you'll see the main page of the admin panel. The appearance may vary, but the sections we need generally have the same names: Network (Net), WAN (Internet), Wireless (Wi-Fi).

⚠️ Attention: If you see the message "No Internet" or "WAN disconnected" on the main page of the admin panel, this means the router isn't receiving a signal from the ISP. Return to the section on physical connection and check the cables.

4. Setting up a connection to ByFly (PPPoE)

This is the most important step - here we provide the data for authorization on the network ByFlyIf you enter an incorrect login, password, or connection type, the internet will not work.

Instructions for most routers:

1. Go to the section Network → WAN (or Internet → WAN Settings).
2. Select connection type: PPPoE (sometimes called PPP over Ethernet).
3. Enter the details from the contract:
   • 🔑 Username: your login in the format login@byfly.by (For example, ivanov123@byfly.by).
   • 🔒 Password: the one specified in the contract (case is important!).

Specify additional parameters (if such fields exist):

• VLAN ID: usually 1 (for ByFly), but may differ in some regions (check with support).
• MTU: leave 1480 (optimal for PPPoE).
• DNS: you can leave it automatic or enter it manually (for example, 8.8.8.8 And 8.8.4.4 from Google).
• Save settings (button Save, Apply or Apply).

After saving, the router will reboot. Wait until it starts working again (the indicators stabilize), and then check your internet connection. To do this:

• Open your browser and try to access any website (for example, ya.ru).
• Check the connection status in the router admin panel - it should be Connected or Online.

If the Internet does not work, check:

• 🔍 Make sure you entered your login and password correctly (a common mistake is extra spaces or incorrect capitalization).
• 🔄 Reboot your router (turn off the power for 30 seconds and turn it on again).
• 📞 Make sure the service is activated in your personal account ByFly (sometimes it takes up to 24 hours after the contract is concluded).

5. Setting up a Wi-Fi network: name, password, and security

Now that the internet is working, all that's left is to configure the Wi-Fi network itself so your devices can connect to it. It's important to choose a strong password and the right security mode.

Go to the section Wireless (or Wi-Fi, Wireless network) and configure the following settings:

• 📛 Network name (SSID):
  • Come up with a unique name (eg. Ivanov_WiFi_5G). Do not use personal information (last name, address).
  • If your router is dual-band, set up separate names for 2.4 GHz And 5 GHz (for example, adding at the end _2G And _5G).
• 🔐 Security:
  • Select encryption type: WPA2-PSK (or WPA3-PSK, if supported). Never use WEP or an open network - it is not secure!
  • Create a complex password (at least 8 characters, with numbers and uppercase and lowercase letters). Example: ByFly_2026!WiFi.
• 📶 Additional settings:
  • Channel: select Auto or manually specify the least loaded one (for example, 6 For 2.4 GHz).
  • Channel width: for 2.4 GHz leave 20 MHz, For 5 GHz — 40 MHz or 80 MHz.
  • Hide network (Hide SSID): Not recommended - this makes connection more difficult without increasing security.

After saving the settings, the router will reboot. You can now connect to your Wi-Fi network from any device by entering the password you created.

If you have devices that do not support WPA2 (for example, older printers or smart plugs), you can enable compatibility mode WPA/WPA2, but this slightly reduces security. An alternative is to set up a guest network with a separate password.

How do I know which Wi-Fi channel is the least congested?

For this you can use applications like WiFi Analyzer (Android) or NetSpot (Windows/macOS). They show all nearby networks and their signal strength. Choose the channel that your neighbors use the least.

6. Typical problems and their solutions

Even after proper setup, difficulties may arise. Let's look at the most common ones and how to resolve them.

Problem	Possible cause	Solution
There is internet, but Wi-Fi doesn't work.	The wireless module is disabled or the settings are incorrect.	Check if Wi-Fi is enabled in the admin panel (section Wireless). Reboot the router.
The network is visible but does not connect.	Incorrect password or incompatible encryption type	Make sure the password is entered correctly (case sensitive!). Check the security type (should be WPA2-PSK).
Slow Wi-Fi speed	Channel congestion or long distance to the router	Change the channel to one with less congestion. Move the router closer to the center of the apartment.
The connection keeps dropping	Signal problems or unstable power supply	Check the cables and power supply. Update the router firmware.
The internet doesn't work on some devices	MAC address restrictions or outdated firmware	Disable MAC address filtering in the settings. Update your device's firmware.

If none of the methods helped, try resetting the router to factory settings (button Reset) and configure it again. It's also a good idea to check if your antivirus or firewall is blocking your network connection.

⚠️ Attention: If after all these steps the internet still doesn't work, please contact technical support. ByFly by phone 123 (for Beltelecom subscribers). Provide them with your router's MAC address (found on the sticker) and check whether your device is being blocked by your provider.

Another useful trick: if you have access to your personal account my.byfly.by, check your connection status there. Sometimes the problem lies in an unpaid bill or temporary restrictions (for example, if you've exceeded your plan's data limit).

7. Optional settings: improving speed and security

Once the basic setup is complete, you can optimize your network. These steps are optional, but they will help make your Wi-Fi faster and more reliable.

• 🔄 Firmware update:

  Manufacturers regularly release updates that fix vulnerabilities and improve stability. Check the current version in the admin panel (section System Tools → Firmware Upgrade) and update if a new version is available.

• 🛡️ MAC address filtering:

  If you want to restrict Wi-Fi access to only your devices, enable MAC filtering in the section Wireless → MAC FilterAdd your gadgets' addresses to the whitelist (they can be found in the network settings on each device).

• 🌐 Guest network:

  Useful if you have frequent guests. Create a separate network with limited access to local resources (section Guest Network). This will protect your personal data.

• 📡 Repeater mode:

  If you have a large house, you can use a second router in repeater mode (Repeater or WDS) to boost the signal. To do this, you will need a model that supports this function (for example, TP-Link TL-WA850RE).

It is also worth paying attention to QoS (Quality of Service) is a feature that allows you to prioritize traffic. For example, you can give maximum speed to video calls (Zoom, Skype) or online games, while limiting torrents. QoS settings are usually located in the Advanced → QoS.

If you use it often IPTV from ByFly, check if the mode is enabled IGMP (in settings LAN or Multicast). Some TV channels may not work without it.

FAQ: Answers to frequently asked questions

Is it possible to connect ByFly directly to a computer without a router?

Yes, but it's inconvenient. To do this, you need to create a PPPoE connection manually in Windows or macOS settings using the username and password from the contract. However, in this case, Wi-Fi won't work, and you won't be able to connect other devices. A router is still preferable.

What should I do if my router doesn't detect the ByFly cable?

Check:

• The cable must be inserted into the port. WAN, and not LAN.
• Try a different cable (the current one may be damaged).
• Make sure the port WAN enabled in the router settings.
• If nothing helps, contact support - the problem may be on your provider's side.

How do I change my ByFly Wi-Fi password?

Go to the router admin panel and find the section Wireless Security (or Wireless Network → Security), enter the new password in the field Password (or Pre-Shared Key) and save the settings. After this, all devices will be disconnected and will need to be reconnected.

Why is Wi-Fi speed slower than cable?

This is normal—wireless connections are always slower than wired connections due to interference and standard limitations. To improve speed:

• Use range 5 GHz (it's faster, but has a shorter range).
• Move the router closer to the device.
• Change your Wi-Fi channel to a less busy one.
• Update your router firmware.

Also check if the speed is limited by your tariff (check in your personal account) my.byfly.by).

Can I use my own router instead of the one provided by Beltelecom?

Yes, but two things need to be taken into account:

• The router must support PPPoE and, preferably, VLAN (although for ByFly the first one is usually enough).
• If you rented a router from a provider, you must return it to the Beltelecom office, otherwise a subscription fee will be charged.

The list of compatible models can be found in support or on forums (for example, Onliner.by). Popular options: TP-Link Archer C6, ASUS RT-AC66U, Keenetic.
