Changing your home Wi-Fi password is the first step you should take when purchasing a new router or if you notice suspicious activity on your network. Beltelecom (trademark ByFly) provides subscribers with equipment from various manufacturers, such as ZTE, Huawei, and Eltex, each with its own management interface. However, the basic security principle remains the same for all devices: access to settings is via a web interface that opens in a browser.
You don't need a computer or laptop to change your security key. A modern smartphone connected to a wireless network can become a fully functional administration tool. Mobile version The router interface is often adapted for gadget screens, making the setup process even more convenient than on a desktop. The main thing is to have a stable connection and know the login address.
In this article, we'll detail the steps for all popular router models installed by your ISP. You'll learn how to find the gateway IP address, what default credentials to use, and how to create a secure encryption key that's impossible to crack using simple methods. Changing your password will immediately disconnect all devices, so you will need to reconnect again with the new code.
Preparing your smartphone for router setup
Before changing security settings, make sure your smartphone has an active connection to the router you plan to configure. This can be via Wi-Fi or a LAN cable if your phone has a suitable adapter (USB-to-Ethernet). It's important to understand that if you're changing your password while away from home, you won't be able to do this remotely without a pre-configured cloud service.
The second important step is to determine the model of your equipment. On the back panel of each router ByFly There is a sticker with technical information. It indicates the exact type of device (for example, ZTE F660 or Huawei HG8245H), as well as standard login details: IP address, administrator username, and password. This information is critical, as without it, access to the control panel will be blocked.
It's also recommended to open a browser on your phone beforehand. Standard browsers work well for Android and iOS. Chrome or SafariIf you use third-party browsers, make sure they have disabled data saving mode or proxy servers, which may block access to the router's local addresses. Built-in ad blockers can sometimes prevent setup pages from loading correctly.
- 📱 Make sure Wi-Fi is turned on on your phone and you are connected to your network.
- 🔍 Find the sticker on the bottom of the router and take a photo of it in case of an input error.
- 🔋 Check your smartphone's battery charge to prevent the device from turning off during the setup process.
⚠️ Note: If you're roaming or using 4G/5G mobile internet instead of Wi-Fi, you won't be able to access your router settings using your local IP address. Be sure to switch to your home wireless network.
Logging into your router's web interface from a mobile device
The authorization process for the router control panel is standard for most models provided by the operator. Open a browser on your smartphone and enter the gateway's IP address in the address bar. For equipment Beltelecom addresses are most commonly used 192.168.1.1 or 192.168.0.1The exact address is always indicated on the aforementioned sticker on the device body.
After entering the address and clicking it, the system will request authorization. You will need to enter the administrator login and password. By default, ZTE and Huawei routers often use the following combination: admin / admin or admin / 1234However, if you previously changed this information or it was changed by the installation wizard, you will need the updated materials. Some newer Eltex models may have a unique login password located on a sticker.
☑️ Check before entry
The interface may not display correctly immediately if the mobile version of the router's website isn't optimized. In this case, try rotating your phone to landscape mode or selecting the "Desktop site" option in your browser settings. This will help avoid issues with pressing small buttons and hidden menus, which are common in older firmware versions.
What should I do if the page doesn't load?
If your browser displays "Unable to access the site" when you enter your IP address, check if you're using mobile data. You can also try clearing your browser's cache or opening an incognito tab. If all else fails, your router may be frozen and need to be rebooted.
Setting up Wi-Fi on ZTE routers (F660, F670)
Equipment brand ZTE is one of the most common on the web ByFly. After successfully logging in (usually at 192.168.1.1) you will see the main menu. You need to find the tab responsible for wireless networks. Depending on the firmware version, it may be called Network, WLAN or Wireless network.
Within this section, look for the subsection Security or SecurityThis is where the field is located. WPA Passphrase or Pre-Shared KeyThis is your current password. Delete the old characters and enter a new combination. We recommend using a mixture of uppercase and lowercase letters and numbers to increase the strength of the key.
Pay attention to the field SSID Name (or SSID1). This is where you set the network name that users see when searching for Wi-Fi. You can change it to any name you like to easily identify your network in an apartment building. Don't forget to save your changes by clicking the button. Submit or Apply at the bottom of the page.
| Parameter | Default value | Recommended value |
|---|---|---|
| IP address | 192.168.1.1 | Leave unchanged |
| Login | admin | admin (or modified) |
| Login password | admin | Complex password |
| Encryption | WPA2-PSK | WPA2/WPA3 Mixed |
⚠️ Note: After changing the password on ZTE routers, a device reboot is often required for the new settings to take effect. If Wi-Fi is lost, wait 1-2 minutes for the router to restart.
Changing the password on Huawei equipment
Routers Huawei, such as the HG8245H series models, have a slightly different interface, but the logic remains the same. Once logged in, go to the WLANIn the menu on the left or at the top, select the item WLAN Basic Configuration or Basic WLAN configuration.
Here you will see a page with the basic wireless network settings. Find the field WPA PreSharedKeyIn some firmware versions, it may be hidden behind asterisks, so there's often a "Show" button nearby, allowing you to see the current password before changing it. Enter the new key in the appropriate field.
Pay special attention to the parameter Authentication Mode. Make sure the mode is selected. WPA2-PSK or WPA/WPA2-PSKUsing an outdated standard WEP or open mode (Open) will make your network vulnerable to hacking in minutes, even by an inexperienced user. After entering the data, click Apply.
Huawei interfaces often have a division into a guest network (Guest Network) and the main one. Make sure you change the password for the main network (usually SSID1) if your goal is to protect your home internet. You can temporarily disable the guest network by unchecking the box. Enable SSID.
Setting up Wi-Fi on Eltex routers
Equipment Eltex (for example, NTU-RG-1421G-W) is less common, but is also actively used by providers. The interface of these devices is more formal and technical. After logging in (often you are required to enter a login) admin and the password from the sticker) go to the section Wireless or Wi-Fi.
Select a subsection from the menu Security or Security settingsHere in the field Passphrase A new password is entered. A unique feature of Eltex is that changes may not be immediately applied until you click "Save" and then apply the configuration. Sometimes a separate "Commit" or "Save Config" action is required.
It's also important to check the frequency range of these routers. Modern models support dual-band (2.4 GHz and 5 GHz). Make sure you change the password for both bands if they're active, or at least for the one to which most of your devices are connected. The 5 GHz frequency provides higher speeds but has a shorter range.
- 📡 Check if WPS mode is enabled. For maximum security, it's best to disable it in the settings.
- 🔒 Make sure the encryption type is set to AES, not TKIP.
- 💾 Don't forget to click the save settings button, otherwise everything will return to normal after reboot.
Creating a strong password and common mistakes
Many users make the mistake of setting passwords that are too simple, such as dates of birth, sequences of numbers (12345678) or words from a dictionary. Modern computing power makes it possible to crack such protection in a matter of seconds. Cryptographic resistance The strength of your password directly depends on its complexity and length.
An ideal Wi-Fi password should be at least 12-15 characters long. Use a combination of uppercase and lowercase letters, numbers, and special characters (if your router supports them). Avoid using personal information that can easily be found on social media. A good practice is to use a passphrase—a set of 4-5 random words separated by special characters.
Another common mistake is ignoring the change of the router administrator password. If you changed the Wi-Fi password but left the default router settings login (admin/admin), an attacker who has access to your network can easily reconfigure the device, block you, or reroute traffic. Always change the password for accessing the management interface.
⚠️ Note: Router interfaces and operator requirements may be updated. If you see differences in menu item names, look for synonyms (Security, Wireless, WLAN) or refer to the official documentation for your specific model.
Troubleshooting after changing your password
After you click "Save" or "Apply," your phone's connection to the router will immediately be lost. This is normal. The device will attempt to reconnect with the old key and, if rejected, may return the error "Unable to connect." You must manually select your network from the list of available Wi-Fi networks and enter a new password.
If your phone displays "Obtaining IP address..." and gets stuck at this point, try selecting "Forget Network" for your Wi-Fi connection on your smartphone. Then, reconnect using the latest information. This will clear old network configuration files from your phone's memory.
In rare cases, especially on older Android or iOS devices, encryption conflicts may occur. If a new device doesn't see the network or can't connect, check the encryption type in the router settings. Setting the mode WPA2-PSK (AES) is the most compatible option for the vast majority of gadgets.
Did your router stop responding after changing settings?
If the router stops providing internet or the web interface disappears after applying these settings, perform a hardware reset. With the router turned on, press the Reset button on the router with a thin object and hold it for 10-15 seconds. The device will return to factory settings, and the password will be the same as on the sticker.
What should I do if I forgot my new password immediately after changing it?
If you changed your password and immediately forgot it, the only way to regain access is to perform a hard reset of the router. To do this, locate the hole marked "Reset" on the powered-on device, press it with a paperclip, and hold it for about 10-15 seconds until the lights flash. After this, the router will return to its out-of-the-box state, and the password will be the one indicated on the sticker.
Is it possible to change the password through the Beltelecom app?
The operator's official app (My ByFly or similar) is primarily designed for monitoring traffic, paying for services, and viewing tariffs. Advanced router configuration features (changing Wi-Fi passwords, port forwarding, MAC address filtering) are usually unavailable through the app. For these purposes, you must use the web interface via a browser.
Does changing your password affect your internet speed?
Changing your password doesn't affect speed. However, changing the encryption type (for example, from WPA2 to WPA3) or frequency (from 2.4 GHz to 5 GHz) can affect your actual connection speed. WPA3 is more secure, but older devices may experience slower performance or fail to connect at all.
Do I need to change my password if my neighbors know my Wi-Fi?
Yes, absolutely. If strangers know your password, they not only consume your bandwidth, slowing down your speed, but they can also potentially access shared folders on your devices or use your network for illegal activities. Changing your password is your first line of defense.
