A modern laptop is a versatile tool for work and entertainment, but its functionality is severely limited without access to high-speed internet. In Belarus, one of the largest providers of telecommunications services is Beltelecom, whose Wi-Fi network is branded ByFly Covers millions of subscribers. Connecting a device to a wireless network may seem simple, but users often encounter complex hardware setup, driver updates, or issues logging into the provider's system.
In this article, we'll cover in detail all the steps required to establish a stable connection between your computer and an access point. You'll learn how to properly configure your router, what to do if your laptop isn't seeing the network, and how to secure your connection from unauthorized connections. Signal stability and correct configuration of network parameters are key factors for comfortable work on the Internet.
Before moving on to technical details, it's worth making sure your equipment is ready for use. This applies not only to the laptop itself, but also to the modem or fiber optic terminal installed by your provider. A critical requirement is to have an active internet access service in your subscriber account. Without this, even perfectly configured equipment will not be able to transmit data to the external network.
Preparing equipment and checking physical connections
The first step to a successful connection is to check the physical status of the devices. Make sure the router or ONT terminal is plugged into a power outlet and the indicators on the front panel are lit or blinking appropriately. If you're using a wired connection for the initial setup, connect an Ethernet cable from the router's LAN port to the laptop's network port. This will ensure a stable connection and prevent interference from wireless airwaves.
Check the WLAN or Wi-Fi indicator on the router. If it's not lit, the wireless module may be disabled either by software or physically. On some models ZTE or EltexWi-Fi devices provided by your provider have a dedicated button to activate Wi-Fi. Press and hold it for a few seconds until the indicator light starts flashing.
You should also check whether the wireless module is enabled on the laptop itself. Older models might have used a physical switch on the side of the case for this, but modern devices control this via software. In the operating system Windows The connection status is displayed in the tray, next to the clock.
⚠️ Attention: If the router's power indicator doesn't light after being plugged in, check the power cable for damage and ensure there's power. Do not attempt to disassemble the power supply yourself, as this may result in electric shock or damage to the device.
It's important to understand the difference between having a signal and having internet access. A router can broadcast a network, but if there's no connection to the provider's equipment, websites won't load. Therefore, checking the physical connection of the provider's cable (fiber optic or twisted pair) running to the WAN or PON port is a must.
Finding and connecting to a wireless network in Windows
Once the hardware has been tested, you can move on to operating system configuration. In Windows 10 and Windows 11, wireless network management is unified and accessible from the taskbar. Click the globe or antenna icon in the lower right corner of the screen. A list of available networks will open.
Find the network in the list with the name that matches your contract or the one on the router sticker (usually starts with ByFly_ or Beeline_(This may be the case if you're using equipment from partner networks, but most often it's a custom name). Click on the network name. If the network is password-protected, the system will prompt you to enter the security key. This default password is located on a sticker on the bottom of the router, unless you've changed it previously.
Enter your password, being careful to ensure that the letters are case-sensitive, and click "Next." The system will attempt to obtain an IP address from the router and test internet access. At this point, a message may appear stating "Obtaining IP address." This process takes anywhere from a few seconds to a minute.
- 📶 Make sure the "Wi-Fi" slider in the taskbar is set to the "On" position.
- 🔒 When you first connect, Windows will ask if you want to make this computer discoverable. For a home network, select "Yes"; for a public network, select "No."
- 🔄 If the connection fails, try right-clicking on the network icon and selecting "Troubleshoot."
Sometimes a laptop sees a network but refuses to connect, displaying the error "Unable to connect to this network." This could indicate an incorrect password, incompatible encryption standards, or a full list of connected devices on the router. In such cases, deleting the saved network profile can help.
To delete your profile, go to Settings → Network & Internet → Wi-Fi → Manage known networksFind the desired network in the list, click it, and select "Forget." Then try connecting again by entering the password again.
Configuring the router via the web interface
If the standard connection isn't working or you need to change security settings, you'll need to access your router's settings. To do this, open any browser (Chrome, Firefox, or Edge) and enter the gateway's IP address in the address bar. For equipment Beltelecom this is most often 192.168.1.1 or 192.168.0.1The exact address is indicated on the sticker on the bottom of the device.
After entering the address, the system will ask for a login and password to access the control panel. The default login information is also located on the sticker (usually admin/admin or user/user). If you changed the password and forgot it, you will have to reset the router to factory settings (Reset).
In the web interface you are interested in the section WLAN or WirelessHere you can change the network name (SSID), select the operating standard (802.11 b/g/n/ac/ax) and set the channel. It is recommended to select mixed mode or 802.11 n/ac for maximum speed.
Pay special attention to the security settings. In the section Security select encryption method WPA2-PSK or WPA3, if your equipment supports it. Using outdated WEP encryption or an open network makes your data vulnerable to interception.
☑️ Checking router settings
After making changes, be sure to click "Save/Apply." The router may reboot. After turning it on, check to see if the network with the new name appears and that the connection is working.
⚠️ Attention: When changing wireless network settings, all connected devices will lose connection and require re-entering the new password. Notify family members in advance of the planned work.
Installing and updating network adapter drivers
A common cause of connection issues is outdated or malfunctioning network adapter drivers. If there are no access points in the list of available networks, or the Wi-Fi icon has a red cross, the problem lies with the software.
To check the driver status, right-click the "Start" button and select "Device Manager." Expand the "Network adapters" branch. Find the device with the words "Network adapters" in its name. Wireless, Wi-Fi or 802.11If there's a yellow exclamation mark next to the device, the driver is not working correctly.
Right-click the adapter and select "Update driver" → "Search automatically for driver software." Windows will attempt to find and install suitable software from its database. If this doesn't help, visit the laptop manufacturer's website (HP, Lenovo, ASUS, Acer), find your device model in the support section and download the WLAN driver from there.
Driver installation requires administrator privileges. Run the downloaded file and follow the installer instructions. Be sure to restart your laptop after the installation is complete.
What to do if the driver is not installed?
If the installation is interrupted or the driver is unsuitable, try removing the current device from Device Manager (right-click → Uninstall device) by checking "Delete driver software." After restarting, Windows will attempt to reinstall the default driver. You can also try installing the driver in compatibility mode with the previous version.
In some cases, especially on older laptops, you may need to manually install the driver via a file. .infIn the driver update window, select "Select a driver from a list of available drivers on your computer" and specify the path to the downloaded file.
Solving common connection problems
Even with proper configuration, occasional glitches may occur. For example, a laptop may connect to Wi-Fi, but still show "No internet access." This often indicates DNS issues or IP address conflicts. Try resetting the network settings via the command line.
Run the command prompt as administrator. To do this, enter cmd In Windows Search, right-click "Command Prompt" and select "Run as administrator." Enter the following commands one by one, pressing Enter after each:
ipconfig /flushdnsipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
After running the last command, restart your computer. This will flush the DNS cache and reset the TCP/IP stack, which often resolves issues accessing specific websites or the internet in general.
Another common issue is slow connection speed. This can be caused by channel congestion from neighboring routers. In your router settings, try changing the wireless network channel from "Auto" to a fixed channel (for example, 1, 6, or 11 for the 2.4 GHz band). For the 5 GHz band, channel selection is less critical, as they don't overlap.
| Problem | Possible cause | Solution method |
|---|---|---|
| The laptop doesn't see the network. | The Wi-Fi module is turned off | Enable via Fn+key or in Windows settings |
| Error: "Unable to connect" | Incorrect password | Delete the network profile and re-enter the password |
| There is a connection, but no internet | DNS or router failure | Reset TCP/IP settings, reboot the router |
| Low speed | Interference on the air | Changing the Wi-Fi channel to 5 GHz |
Wi-Fi Security and Optimization
Once you've successfully connected, it's important to secure your network. The default password listed on your router is often too simple or publicly accessible. Change it to a complex password that includes mixed-case letters, numbers, and special characters.
It's also recommended to disable WPS (Wi-Fi Protected Setup). While it offers the convenience of a one-click connection, this protocol has vulnerabilities that allow attackers to quickly brute-force the PIN and gain access to your network. You can disable WPS in the wireless security section of the router's web interface.
For optimal performance, ensure the router is located in a central location within the apartment, away from microwaves, baby monitors, and other sources of 2.4 GHz radiation. Metal structures and mirrors can also block the signal.
⚠️ Attention: Don't use programs to "hack" your neighbors' Wi-Fi. Not only is it illegal, it's also dangerous: such programs often contain viruses that can steal your passwords to banking apps and personal accounts.
Regularly check the list of connected clients in the router interface. If you see an unknown device, immediately change your Wi-Fi password and scan your computers for viruses.
Frequently Asked Questions (FAQ)
Where can I find my Wi-Fi password if the sticker on my router has worn off?
If you haven't changed the password yourself, you can find it in the router's web interface. Go to the settings at 192.168.1.1 (or another address specified in the instructions), enter your username and password (often admin/admin). Then go to the WLAN or Wireless Security section—the password will be listed in the WPA Pre-Shared Key field. If you've changed the password and forgotten it, you'll have to reset the router using the Reset button.
Why does the laptop see the 2.4 GHz network, but not the 5 GHz?
Most likely, your laptop's network adapter is outdated and doesn't support the 802.11ac or ax standard, which operates in the 5 GHz band. Check the laptop model's specifications on the manufacturer's website. It's also possible that the network name (SSID) for the 5 GHz band is hidden in the router settings or disabled.
How do I find out who is connected to my Beltelecom Wi-Fi?
Access your router settings via a browser. In the menu, find the "Status," "Device Info," or "Client List" section. This displays a list of all devices currently accessing the internet through your router, along with their MAC addresses and names.
Is it possible to connect a laptop to Wi-Fi without entering a password?
A secure connection without entering a password is only possible using WPS technology (by pressing a button on the router and in the Windows interface), but both devices must support it. Otherwise, entering a security key is required to encrypt data.
What should I do if Wi-Fi disappears after a Windows update?
Operating system updates sometimes replace working drivers with default ones, which may not work correctly with your adapter. Visit the laptop manufacturer's website, download the WLAN driver for your model, and install it manually, after first uninstalling the current driver in Device Manager.
