Modern Internet provider ByFly, which provides broadband access services, often uses fiber optic modems from the company as terminal equipment Huawei. Model HG8245H While the Wi-Fi network has proven itself to be a reliable device capable of providing a stable connection, it is often configured with basic security settings out of the box. Users must manually change the factory settings to prevent unauthorized access to their personal network. This is a critical step that should be completed immediately after installation.
The process of configuring a wireless network does not require in-depth knowledge of networking technologies, but it does require care when entering data. Interface The device's management interface is logical, but may differ from that of other routers. In this article, we'll cover every step in detail: from physical connection to fine-tuning frequency ranges. You'll learn how to create guest networks and optimize the signal for optimal speed.
Incorrect settings can result in slow speeds or constant connection drops. Therefore, it's important to follow the steps described below and verify the entered values. We'll cover standard usage scenarios and also cover advanced settings that can help improve signal quality in multi-apartment buildings.
Preparing for setup and logging into the web interface
Before changing wireless network settings, ensure your device (computer, laptop, or smartphone) is properly connected to the modem. This can be done in two ways: via an Ethernet cable plugged into the LAN port, or via Wi-Fi using the information on the manufacturer's label. Experts recommend using a wired connection for initial setup, as it ensures a stable process and seamless connection while saving settings.
Once physically connected, open any modern web browser. Enter the device's IP address in the address bar. For hardware Huawei, provided by the ByFly provider, the standard address is usually 192.168.100.1In some cases, if your ISP has changed the default addressing scheme, the address may differ. If the page doesn't open, check your computer's network card settings—they should be set to obtain an IP address automatically (DHCP).
When you navigate to the address, you'll see a login window. You'll need your login and password. Factory-installed login information is often found on the same sticker as the network's SSID. However, for modems HG8245H The standard pair: login is often used telecomadmin and password admintelecomIf this information is not suitable, your provider may have blocked access to the advanced menu, in which case you should use a user account, such as login. user and the password indicated on the sticker.
⚠️ Warning: If the default superuser passwords don't work, don't try to guess them. Multiple unsuccessful login attempts may temporarily block access to the modem's web interface. In this case, it's best to contact your ISP's technical support to verify your login information.
After successful authorization, the control panel will open. The interface may be in English or Russian, depending on the firmware version. The main navigation is usually located at the top or left side of the screen. We'll need the section responsible for wireless settings, often called WLAN or Wireless.
Basic Wireless LAN (WLAN) Configuration
Once you've entered the WLAN settings section, you'll see several tabs or subsections. We're interested in the basic configuration, where you set the basic network visibility and naming parameters. First, find the field SSID Name (Service Set Identifier). This is the name that will appear in the list of available networks on your phones and laptops. By default, it contains the model name and a random set of characters. It is recommended to rename the network to something recognizable, such as "Home_Net" or "Apartment_WiFi," to easily identify your device among others in the neighborhood.
Next, you need to configure the encryption settings. In the field Authentication Mode (Authentication Mode) Be sure to select the option WPA2-PSK or WPA2/WPA MixedUsing the outdated WEP or Open network standard makes your data vulnerable to interception. Modern devices work well with the WPA2 protocol, providing a high level of protection for transmitted information.
The most important element is the field WPA PreSharedKey or WPA PasswordThis is where you set the password you'll need to enter to connect new devices. The password should be complex: at least 8 characters long, including uppercase and lowercase letters, numbers, and special characters. Avoid using simple sequences or birthdays.
- 🔒 SSID Name — the name of your network, visible to surrounding devices.
- 🔑 PreSharedKey — a security key required to connect clients.
- 🛡️ Authentication Mode — an encryption protocol that protects traffic from eavesdropping.
- 📡 Channel Width — channel width, which affects the speed and range of the signal.
After entering all the required data, be sure to click the button Apply or SaveThe modem will apply the new settings, and the wireless connection will be restarted. If you configured the network via Wi-Fi, your device will disconnect, and you'll need to find the new network using the changed name and connect using the new password.
Setting up the 2.4 GHz and 5 GHz bands
Modem Huawei HG8245H A wireless router is often a dual-band device, supporting both the 2.4 GHz and 5 GHz frequency ranges. Each of these ranges has its own unique characteristics and advantages. The 2.4 GHz band has better wall penetration, but it's often overloaded with signals from neighboring routers, microwave ovens, and Bluetooth devices. The 5 GHz band offers significantly higher data transfer rates and is less congested, but has a shorter range.
In the modem interface, these ranges can be configured in separate tabs, for example, 2.4G Basic Network Settings And 5G Basic Network SettingsYou can create two different networks with different names (for example, "Home_2.4" and "Home_5") to manually select which one to connect to depending on the task. For 4K video streaming or online gaming, 5 GHz is best, while 2.4 GHz is suitable for smart home use and simple browsing.
⚠️ Please note: Not all older smartphones and smart home gadgets support the 5 GHz frequency. If you hide the 2.4 GHz network or set a complex password, some devices may simply not see the network or be unable to connect to it.
It's also worth paying attention to channel selection. In automatic mode, the modem automatically selects the least congested channel, but in densely populated areas, the algorithm may not work correctly. For the 2.4 GHz band, it's recommended to manually select channels 1, 6, or 11, as they don't overlap. For 5 GHz, you can leave the automatic selection or select channels in the 36-48 or 149-165 ranges, which are usually freer.
What is the difference between 20 MHz and 40 MHz channel width?
A 20 MHz channel width provides a more stable signal and is less susceptible to interference, making it ideal for the 2.4 GHz band in apartment buildings. A 40 MHz channel (or higher for 5 GHz) doubles the potential speed but increases the risk of interference with neighboring networks. If you have many neighboring networks, it's best to force the 2.4 GHz band to 20 MHz.
Device Filtering and Security (MAC Filter)
To enhance the security of your Wi-Fi network, you can use MAC address filtering. A MAC address is a unique identifier for the network interface of each device (Wi-Fi card in a phone, laptop, or TV). By setting up a whitelist, you allow connections only to devices whose addresses are entered in the modem's settings table. All other devices, even with the password, will be unable to access the network.
To implement this, go to the section WLAN MAC Filter ConfigurationHere you need to enable the filtering function and select the mode Allow (Allow). Then add the MAC addresses of all your trusted devices. You can find the MAC address in your phone's settings (under "About Phone" or "Status") or on the device's sticker. This method provides reliable protection against "neighbor spying," even if the password has been compromised.
However, this method has a significant drawback: it's inconvenient when connecting guests. Every time friends come over with their own devices, you'll have to manually enter their MAC addresses into the modem settings, otherwise their internet won't work. Therefore, this method is recommended for apartments where the set of connected devices is constant and rarely changes.
| Parameter | Description | Recommended value |
|---|---|---|
| Filter Mode | Filter operating mode | Allow (Whitelist) |
| MAC Address | Unique device address | Format XX:XX:XX:XX:XX:XX |
| Status | Rule activity | Enable |
| Comment | Device description | For example: iPhone_User |
Keep in mind that if you buy a new gadget or replace your smartphone, you'll need to repeat the MAC address addition process. It's also worth considering that some modern devices use a "MAC address randomization" feature to protect your privacy on public networks. On your home network, it's best to disable this feature for your Wi-Fi network in your phone's settings; otherwise, the modem will see it as a new, unknown device.
Signal optimization and additional features
In addition to the basic settings, the modem Huawei HG8245H offers a number of additional features to optimize operation. One of them is transmitter power adjustment (Transmit Power). By default, it's set to 100%, which isn't always optimal. If the modem is located in a small apartment, reducing the power to 75% or 50% can reduce electromagnetic radiation and minimize interference without degrading connection quality within the room.
Another useful feature is the creation of a guest network (Guest Network). This allows you to create a separate access point with its own username and password. Guests will be connected to an isolated network, without access to your main devices, such as network printers, NAS storage, or smart cameras. It's an excellent compromise between hospitality and security.
In the additional settings section you can also find the function WPS (Wi-Fi Protected Setup). It allows you to connect devices with the press of a button, without entering a password. For security reasons, it's best to disable this feature.Disable), as it is a vulnerable spot through which attackers can try to guess the PIN code and gain access to the network.
☑️ Wi-Fi Security Checklist
Common problems and their solutions
Users may encounter various difficulties during setup. One of the most common issues is the device not detecting the network after renaming it or changing the channel. In this case, try completely forgetting the network on your phone (using the "Forget Network" or "Delete Profile" function) and then rediscovering it. Restarting the modem itself by turning it off for 10-15 seconds also helps.
If your Wi-Fi internet speed is significantly slower than your cable connection, check the frequency your device is using. Switching from 2.4 GHz to 5 GHz often resolves the slow speed issue. It's also worth checking whether your modem is located in a closed cabinet or behind a TV, which could block the signal.
⚠️ Note: The interface and available features may vary depending on the firmware version installed by your provider. ByFly may restrict access to advanced settings. If you don't see the options described, please consult the official documentation or contact support.
Another common issue is an IP address or DHCP server conflict if there is another router on the network. Make sure the modem HG8245H Operates in router or bridge mode, depending on your connection setup. For standard use with a single device, router mode with DHCP enabled is sufficient.
Frequently Asked Questions (FAQ)
Where can I find the factory Wi-Fi password if I haven't changed it?
The factory password (WPA Key) is always indicated on the information sticker located on the bottom or back of the modem. Huawei HG8245HLook for a field labeled "WPA Key," "Wireless Password," or "Wi-Fi Key." If the sticker has worn off and you haven't changed the password, you can try the default combinations, but it's safer to reset the modem to factory settings using the button. Reset.
How to reset the Huawei HG8245H modem to factory settings?
To reset, find the small hole on the case with the inscription Reset or DefaultTurn on the modem, take a paperclip, and press the button inside the hole. Hold it for 10-15 seconds until the lights blink simultaneously. After this, the modem will reset to factory settings, and you'll have to set up the internet and Wi-Fi again.
Why doesn't the modem save settings after rebooting?
If the settings are lost after a power outage, this may indicate a faulty modem's internal memory or that the provider is forcibly resetting the configuration remotely (TR-069 protocol). In the first case, the device requires repair; in the second, you should confirm the desired settings with the provider's technical support.
Is it possible to boost the Wi-Fi signal on this modem?
It's impossible to boost the signal beyond the factory limits using software, as the transmitter power is limited by standards and firmware. However, coverage can be improved by properly positioning the modem, changing the channel to a less crowded one, or connecting an external antenna if the modem model has connectors for them (the HG8245H typically has built-in and non-removable antennas, so this option is not suitable; the only option is a repeater).
