For your convenience, the material is divided into logical sections—from simple to complex—with visual cues and interactive elements.

1. Preparing for connection: checking equipment and requirements

Before you begin setting up your system, make sure all system components are ready to use. Let's start with a check. hardware:

• 📡 ByFly router: must be plugged into the network and correctly connected to the operator line (indicator DSL or Internet (lights up green).
• 💻 Laptop: Check that the Wi-Fi adapter is physically turned on (some models have a separate switch on the case).
• 🔌 Nutrition: the router and laptop must be connected to the power supply (especially important for laptops with a discharged battery).
• 📄 Documents: prepare the connection data - network name (SSID) and password (indicated on the router sticker or in the contract).

If you are using the router provided ByFly, please note that by default the network name (SSID) often contains the serial number of the device (eg BYFLY-XXXX-5G). A password usually consists of 8-12 characters, including numbers and letters in different upper and lower case.

⚠️ Attention: If you are connecting to the network for the first time after activating the service, wait for an SMS from ByFly with confirmation of the internet startup. In rare cases, a router reboot is required (hold down the button Reset for 10 seconds).

Also check if your laptop supports the standard Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax), if the router is operating in one of these modes. Older devices (manufactured before 2015) may not see networks in the range 5 GHz.

2. Basic Wi-Fi setup on a Windows laptop

The easiest way to connect is to use the built-in tools WindowsThe instructions are suitable for both OS versions (10 and 11), the differences are minimal.

Open Wi-Fi Control Panel:

1. Click on the network icon in the lower right corner of the screen (next to the clock).
2. In the list of available networks, find the name of your Wi-Fi (for example, BYFLY-1234).
3. Click on the network name and enter the password (case sensitive!).
4. Check the box "Connect automatically" and press "Next".

If everything went well, a connection icon will appear next to the network icon, and the start page will open in the browser. ByFly (or any other). If not, proceed to the next section.

The power indicator on the router has been checked. The laptop is within Wi-Fi coverage. Airplane mode is disabled. The password has been entered correctly.

⚠️ Attention: On laptops Lenovo, HP And Dell sometimes the Wi-Fi blocking is triggered via the function keys (for example, Fn + F2). If the network is not listed, try this combination.

For users Windows 11 There is an alternative way: Settings → Network and Internet → Wi-FiHere you can manually add a network if it does not appear in the list.

3. Manually adding a Wi-Fi network (if automatic doesn't work)

If your network ByFly If it's not visible in the list of available networks, you can add it manually. This is relevant for hidden networks (SSID hidden) or if there are problems with drivers.

Instructions for Windows 10/11:

   • 🔒 Security type - usually WPA2-Personal (less often) WPA3).
   • 🔑 Security key — password from the contract.

Save the settings and try to connect.

If the connection is not established after manual addition, check whether the network is blocked by an antivirus (for example, Kaspersky or Avast). Temporarily disabling the firewall will help diagnose the problem.

4. Connection optimization: channel and band selection

If Wi-Fi is unstable (frequent interruptions, low speed), the problem may lie in channel congestion or incorrect selection of range (2.4 GHz vs 5 GHz).

First, determine what range your router supports:

• 📶 2.4 GHz — large coverage area, but lower speed and higher interference from neighboring networks.
• 🚀 5 GHz - high speed, but shorter range (walls weaken the signal).

To change the band or channel, go to the router settings:

1. Open your browser and type in the address bar 192.168.1.1 (or 192.168.0.1 for some models).
2. Log in (the default login and password are often admin/admin or user/user).
3. Go to the section Wireless (or Wi-Fi → Basic Settings).
4. Select your preferred range (Band) and channel (Channel). For 2.4 GHz recommended channels 1, 6 or 11 (they do not intersect).

To analyze channel load, you can use free utilities like Wi-Fi Analyzer (For Android) or NetSpot (For Windows/macOS). They will show you which channels are free in your area.

5. Troubleshooting Wi-Fi adapter drivers

If your laptop doesn't see the network at all or connects with errors, the culprit may be Wi-Fi adapter driverThis is especially relevant after a Windows update or system reset.

Check the driver status:

1. Click Win + X and select "device Manager".
