Many ByFly subscribers are familiar with the situation of urgently needing to connect a new smartphone or laptop to their home network but have lost the password. Users often forget the character combination they entered during the initial setup of their equipment or simply didn't pay attention to it. In most cases, factory data for authorization in a wireless network do not disappear anywhere; they are physically present on the device body.
However, finding this information can turn into a quest if you don't know where to look. On modems and routers provided by your ISP BeltelecomStickers can be located in different places depending on the manufacturer and year of manufacture of the device. Sometimes the label fades, wears off, or comes off, requiring alternative methods to restore internet access.
In this article, we will examine in detail all possible options for the location of factory data, and consider the differences between models ZTE, Huawei, Sercomm And TP-LinkWe'll also explain what to do if the sticker is illegible. You'll learn not only how to find the security key but also how to change it to a more complex one using the web interface.
Find the factory sticker on the device body
The first and most obvious place where the manufacturer is required to indicate the basic settings is the information sticker. On devices ByFly It usually contains the provider's logo, barcode, serial number and designation lines. SSID (network name) and Wireless Key or WPA/WPA2 Key (password). This combination of characters is the key for the initial connection.
The label's location depends directly on your router's form factor. If you have a classic "horizontal" router with antennas, flip it over. The label is almost always located on the bottom edge to avoid disturbing the top panel's design. Make sure the device is stable before lifting it to avoid damaging the cables.
In the case of vertical modems or optical terminals GPONThe sticker is often hidden on the back panel, near the cable ports or reset button. This is done for ease of access, as these devices are often stored in niches or on shelves where turning them over is difficult. Run your finger along the back panel to ensure there is no sticker.
⚠️ Caution: If the sticker is heavily worn and the text is illegible, do not attempt to remove it with harsh chemicals. Alcohol-based solvents can permanently destroy the sticker, making the information irretrievable.
Sometimes users encounter a situation where the sticker indicates that the password matches serial number devices. In this case, look for a long string of numbers and Latin letters, designated as S/N or Serial NoOften this combination is the default key.
Data layout features on different router models
The equipment used by the provider is supplied by different vendors, and each has its own labeling nuances. Understanding these differences will help you navigate the situation more quickly, especially if you're using a device without a clear label. ByFly.
Let's look at the main differences in the labeling of popular models:
- 📡 ZTE (F660, F670 series): These optical terminals often have a sticker located on the bottom of the case. The password can be specified as
WPA Passphraseand consist of 8-10 characters. - 📡 Huawei (HG8245, EG8145 series): On many models Huawei The factory password is the same as the MAC address (a set of characters without colons) or is specified separately as
WLAN KeyThe label is usually white with black font and is located on the back. - 📡 Sercomm (FG8010): These devices often have a sticker on both sides or duplicate information on the side. The password may be hidden under a protective layer that can be scratched off with a coin.
- 📡 TP-Link (Archer series): If the router has been reflashed by the provider, the sticker ByFly It's glued over the factory one. Look for the top sticker, as the factory data TP-Link in this case they are no longer relevant.
It's important to understand that if the equipment has been repaired or replaced under warranty, it may have a new service center label. In this case, the information on the label will be current at the time the device was issued, but it may have been changed by the technician during setup.
⚠️ Note: Some older router models may not have a default Wi-Fi password (the network is open). This field on the sticker will be marked with a dash or "None."
If you find multiple stickers, always prioritize the one with the carrier's logo. The vendor's factory settings may have been reset or changed when the service line was activated.
What to do if the sticker comes off or wears off
It's not uncommon for the information you need to be physically missing from the device's casing. The adhesive dries out, the labels fall off, and the text fades when exposed to sunlight. However, this doesn't mean you'll lose your network access if you have at least one device already connected to the same Wi-Fi network.
If you have a computer or smartphone that has previously successfully connected to this network, you can view the saved password in its settings. Windows This is done through the Network and Sharing Center, Android — via QR code in Wi-Fi settings (on versions 10 and higher), and on iOS — via the password transfer function to another Apple device or viewing in iCloud Keychain.
Let's consider the algorithm of actions for different scenarios:
- 🔑 Via Windows: Go to
Control Panel → Network and Internet → Network and Sharing CenterClick on the name of your wireless network, selectWireless network properties, go to the tabSecurityand check the boxShow entered characters. - 🔑 Via Android: Open Wi-Fi settings and tap the gear icon next to your network. If there's a "Share" button or QR code, point the other phone's camera at it—the password is often displayed in text below the graph or in a notification.
- 🔑 Via macOS: Open Keychain via Spotlight search, find your network name, double-click and check the "Show password" box, confirming the action with Touch ID or your account password.
Please note that if security settings have previously been changed manually, viewing the saved password on the connected device will show the current key, not the factory default. This is often even more useful than searching for the sticker.
Viewing the password through the router's web interface
The most secure way to find out or change the password without accessing the connected devices is to log into the router's control panel. To do this, you need to connect to the device via cable. LAN Or, if the network is open/the password is known to one device, via Wi-Fi. The login address is usually on the same sticker as the password.
Standard addresses for entering the management interface:
- 🌐
192.168.0.1— is often used for TP-Link, D-Link, Tenda. - 🌐
192.168.1.1— standard for Huawei, ZTE, Asus, Beeline. - 🌐
192.168.100.1- sometimes found on optical terminals GPON.
After entering the address in the browser, the system will ask for a username and password to access the settings. Don't confuse these with your Wi-Fi password! A pair is often used by default. admin / admin or admin / passwordThis information may also be duplicated on the sticker.
Once inside, look for a section titled WLAN, Wireless, Wi-Fi or Wireless networkThere should be a tab inside this section. Security (Security) or BasicIn the field WPA Pre-Shared Key, Passphrase or Password The current character combination will be displayed. You can copy it or replace it with a new one.
What should I do if I can't access the settings?
If the default login and password (admin/admin) don't work, they were changed during initial setup. Check if you wrote them down in a notepad. If not, a full reset of the device using the Reset button will help.
The interface may differ depending on the firmware. From the provider Beltelecom Often, there's a customized version of the software, where sections may be called "Wi-Fi Settings" or "Home Network." Be careful when switching between tabs.
Standard data table for popular models
To help you find information quickly, we've organized data on the most common router models found in subscriber networks. Please note that your provider may make changes to the default configurations.
| Device model | Entrance address | Default login | Default password |
|---|---|---|---|
| ZTE F660 / F670 | 192.168.1.1 | admin | admin (or from the sticker) |
| Huawei HG8245H | 192.168.100.1 | telecomadmin | admintelecom |
| Sercomm FG8010 | 192.168.1.1 | admin | admin |
| TP-Link Archer C6 | 192.168.0.1 | admin | admin |
| Eltech 150-1 | 192.168.0.1 | admin | admin |
The data in the table is valid for factory settings. If the router was configured by a wizard during setup, the web interface password may have been changed to a unique one. In this case, the table won't help, and a reset will be required.
Factory reset (Hard Reset)
If none of the above methods work, or you don't remember the password to access the router settings, there's one last, radical but effective method: a hard reset. This procedure will return the device to its out-of-the-box state, and the Wi-Fi password will be the one on the sticker (or the default one for this model).
To perform a reset, find a button or hole with an inscription on the case Reset or RestoreThis is usually a small indentation where you need to press with a paperclip or toothpick. You need to be careful not to damage the internal contacts.
Reset instructions:
- Plug the router into a power outlet and wait until it boots up (the indicators light up).
- Press and hold the button
Resetwithin 10-15 seconds. - Watch the indicators: when they all flash at the same time or go out, you can release the button.
- Wait for the device to reboot (1-2 minutes).
☑️ Checklist before reset
⚠️ Please note: After resetting, the router will "forget" your provider settings. Internet access may not work until you re-enter your login information (username and password from your contract) in the web interface.
This method is guaranteed to restore access if the sticker is present. If the sticker is missing, resetting will return the default password, which can be found online for the device model. However, it may not work if the provider uses unique keys.
Frequently asked questions and problems when searching
Users often encounter nuances that aren't covered in the quick start guides. For example, confusion between the PIN code and the WPA2 password. There may be a field on the sticker PIN — This is a code for quick connection using WPS technology; it is not suitable for regular password entry on the phone.
Another issue is case sensitivity. Passwords are case sensitive. If there's a letter on the sticker, O, it can be a letter, not zero 0In label fonts, they often look identical. Try both options if the connection fails.
It is also worth remembering that some providers use technology TR-069, which allows you to remotely manage your router settings. Theoretically, support can view your current password or reset it remotely if you call the call center.
