Changing the password on your home Wi-Fi router is the first step you should take if you notice a drop in internet speed or the detection of unauthorized devices on your network. Byfly (Beltelecom) provides subscribers with equipment from various manufacturers, such as ZTE, Huawei or Eltex, and their settings interfaces may differ significantly. However, the basic principle of access point security remains the same for all models.
In this detailed guide, we'll walk you through the steps for the most popular routers used in a Belarusian ISP's network. You'll learn not only how to set up a strong encryption key but also how to choose the right security type to keep your internet fast and secure.
Before making any changes, make sure your device (computer or smartphone) is connected to the router. This can be done either wirelessly or, more reliably, via LAN cable, connected to one of the yellow ports on the back of the device.
⚠️ Attention: If you change settings wirelessly, the connection will be immediately lost after changing the password. You'll have to reconnect to Wi-Fi using the new access key.
Changing access data requires administrative rights. Make sure you know the login and password for logging into the router's web interface. By default, the equipment Byfly Standard combinations are often used and are indicated on the sticker on the bottom of the case.
Identifying your router model and accessing the control panel
The first step is to identify your equipment. On the back of each router Byfly there is an information sticker where the exact information is indicated model number devices (for example, ZTE F660, Huawei HG8245H or Eltex NTU-2G). This information determines the address you need to go to for setup.
Open any browser on a device connected to the router. Enter the gateway IP address in the address bar. For most devices, Byfly This 192.168.1.1 or 192.168.0.1If none of the addresses open, check your network card settings or use the command ipconfig in the command line to search for "Default gateway".
After entering the address, the system will ask for authorization. Standard credentials are also printed on a sticker (often admin/admin or user/user). If you have changed them before and forgot, you will need a full resetting the router to factory settings via button Reset.
What to do if the default password doesn't work?
Default passwords may not work if the settings were changed by the technician during installation or by the previous owner of the equipment. In this case, the only solution is a factory reset. Find the small hole marked "Reset" on the router, take a paperclip, and press and hold the button for 10-15 seconds while the power is on. The router will reboot, and the password will return to the value on the sticker.
Setting up Wi-Fi on ZTE routers (F660, F670, 680)
Equipment brand ZTE is one of the most common on the web ByflyThe interface of these devices is logically structured, but requires careful selection of frequency ranges. Modern models support dual-band operation. 2.4 GHz And 5 GHz.
After successful login, go to the top menu and select the tab Network (Network). In the list that opens on the left, find the item WLAN (Wireless network). Next, you need to select the subsection Security (Security) or SSID Settings (SSID settings), depending on the firmware version.
In the field WPA Pre-Shared Key or Passphrase Enter a new, complex password. We recommend using a combination of mixed-case letters, numbers, and special characters, at least 10 characters long. Make sure that in section Authentication Type value selected WPA2-PSK or WPA/WPA2-PSK, as this provides the most secure encryption.
☑️ ZTE Security Check
Don't forget to press the button Submit or Apply at the bottom of the page to save your changes. If your router is dual-band, repeat the process for the second band, as passwords for 2.4 and 5 GHz frequencies can be set independently.
Changing the password on Huawei and Eltex devices
Routers Huawei (series HG8245, HG8247) and Eltex have their own interface features. Huawei A simplified menu is often used, where the main settings are located on the main page or in a tab WLANIt is important to pay attention to the checkbox here. Enable WLAN - She must be active.
To change the password on Huawei go to WLAN -> WLAN Basic ConfigurationIn the field WPA PreSharedKey Enter a new combination. Pay special attention to the field SSID Name — This is the name of your network that other users see. You can also change it for personalization.
Devices Eltex (often found in new GPON connections) have a more technical interface. The settings path usually looks like this: Configuration -> Wireless -> Security. Here you may need to select a specific one. SSID Index (usually it is SSID1), for which the settings are applied.
After making all changes to the security fields on Eltex And Huawei Be sure to press the button Save/ApplyThe interface may take a few seconds to reboot. If you've changed the settings of the currently active network, the connection will be lost immediately after pressing the button.
Selecting encryption type and security standards
The security of your network directly depends on the encryption protocol you choose. In your router settings Byfly You can find several options: None (open network), WEP (outdated), WPA, WPA2 and new WPA3Using open networks or the WEP protocol makes your traffic vulnerable to interception, even by non-professionals.
The optimal choice at the moment is the standard WPA2-PSK (AES)It provides a high level of protection and is compatible with all modern devices, from smartphones to smart kettles. Protocol WPA3 It's even more reliable, but older gadgets may simply not see your network or refuse to connect.
Below is a comparison table of security protocols available in routers. Byfly:
| Protocol | Security level | Compatibility | Recommendation |
|---|---|---|---|
| Open / None | Absent | All devices | Strongly not recommended |
| WEP | Very low | Old devices | Do not use, hacks in minutes |
| WPA-PSK (TKIP) | Average | Devices before 2010 | Use for compatibility only |
| WPA2-PSK (AES) | High | All modern devices | Optimal Choice (Recommended) |
| WPA3-Personal | Maximum | New devices (2018+) | For advanced users |
When selecting mixed mode WPA/WPA2 The router attempts to negotiate the most secure protocol with the connecting device. This is a good solution if you have a variety of devices of different ages in your home.
Setting up guest access and MAC address filtering
If you have frequent guests or want to secure your main network, use the feature Guest Wi-Fi (Guest Network). It allows you to create a separate access point with its own password that doesn't have access to your local files and printers, but does provide internet access.
In routers ZTE And Huawei The guest network is configured in the same section WLAN, but requires activation of a separate SSID (for example, Byfly_Guest). You can set a time limit or speed limit for guests so they don't interfere with your main work.
For maximum protection you can use MAC address filteringThis is a whitelist of devices allowed to connect. Even if someone knows your password, they won't be able to connect if their device isn't on the list. You can find the MAC address in your phone's settings or on a sticker on your device.
⚠️ Attention: MAC address filtering is a reliable but labor-intensive method. Every time a friend comes over with a laptop, you'll have to manually enter their network card address into your router settings.
Enabling guest mode is also useful for smart home devices with weak security. By placing them on an isolated network, you minimize the risk of hacking the main infrastructure.
Common problems and solutions
Users often encounter a situation where, after changing the password, the device displays "Unable to connect" or endlessly attempts to establish a connection. First, try "Forget the network" on your smartphone or laptop, then re-enter the new password. A cache of old settings may be interfering with authorization.
Another common issue is character incompatibility. Some older devices may incorrectly recognize passwords containing spaces, Russian letters, or special characters like & or #If you have connection problems, use only Latin characters and numbers.
If the router's web interface stops responding after making changes, there may be an IP address conflict or a firmware error. Try rebooting the router using the power button. In extreme cases, a reset using the button may help. Reset, but this will return all settings, including provider authorization data (PPPoE), if they were not saved in the profile.
Why doesn't the router save the new password?
Sometimes settings aren't saved due to full router memory or a firmware error. Try changing the network name (SSID) first, save it, and then change the password. Also, make sure you don't use reserved characters in the password field.
Recommendations for creating a strong password
The strength of your password is determined by how difficult it is to brute-force. Simple combinations like 12345678, password A password or phone number can be hacked in seconds using special programs. The password must be unique and complex.
Use mnemonic phrases. Take a line from a favorite song or quote and use the first letters of the words, adding numbers and symbols. For example, the phrase "My cat likes to sleep twice a day!" becomes a password. Mkl_s2rd!This set of characters is extremely difficult to guess, but easy to remember.
- 🔒 Use at least 12 characters for maximum security.
- 🔢 Combine uppercase and lowercase letters, numbers, and punctuation.
- 🚫 Avoid obvious data: dates of birth, names, addresses.
- 🔄 Change your password at least once a year or if you suspect a hack.
Write down your new password in a safe place or use a password manager. If you forget your complex access key, you won't be able to recover it from the router settings—you'll only see asterisks or enter a new one, which will require reconnecting all devices.
Is it possible to recover a forgotten Wi-Fi password without resetting the router?
If you have a Windows computer that's previously connected to this network, you can view the saved password. Go to "Network Settings," select "Network and Sharing Center," click the name of your wireless network, then "Wireless Network Properties" -> the "Security" tab, and check "Show characters as you type."
Does changing your password affect your internet speed?
Changing your password itself doesn't affect speed. However, if you've had a lot of other users connecting to your network ("neighbor traffic"), changing your password and removing the unnecessary load may significantly improve your connection speed.
What should I do if my Smart TV doesn't work after changing my password?
TVs often cache network settings. You need to go to the network settings on the TV itself, find your network, select "Forget" or "Delete," then search again and enter a new password.
