Changing your home Wi-Fi password is a basic digital hygiene procedure that every internet user in Belarus should master. Regardless of whether you use A1, ByFlyWhether you're using a mobile phone, MTS, or a local ISP, the router's default factory settings are an open door for attackers. With so many smart devices connected to the network, from smartphones to CCTV cameras, securing your access point becomes critical.
Changing the access key doesn't require in-depth technical knowledge, but it does require attention to detail. Incorrect actions can result in loss of access to the router's settings, requiring a full factory reset. In this article, we'll detail the steps for the most popular router models in Belarus, including ZTE, Huawei And MikroTik, which are supplied in bulk by telecom operators.
Before you begin setting up your router, make sure your device (laptop or phone) is connected to the router. This can be done either wirelessly or via LAN cable, which is a more secure method that prevents connection interruptions during the configuration process. If you change the password now, be prepared for all devices to disconnect from Wi-Fi immediately after saving the settings and will need to be reconnected with the new code.
Preparing to change security settings
The first step in upgrading your network's security is gathering the necessary information and ensuring a stable connection. You'll need to know the gateway IP address, as well as the administrator username and password for accessing the router's web interface. In Belarus, providers most often use standard addresses, such as 192.168.1.1 or 192.168.0.1, but they may vary depending on the equipment model.
Pay attention to the sticker on the bottom of your router. This is where manufacturers such as ByFly or A1, specify the factory authorization data. If you previously changed this data and forgot it, the only solution is a physical reset using the button. ResetThis action will reset the device to its original state, and you will have to reconfigure your internet connection if your ISP does not use automatic MAC address authentication or PPPoE with binding.
⚠️ Attention: Before you begin any manipulations, make sure you have a wired connection or an alternative communication channel (mobile Internet) so that in case of an error you can find up-to-date instructions or contact technical support.
Router management interfaces may vary, but the logic behind their operation remains the same for most devices. You'll need to find the section responsible for the wireless network, often labeled as Wireless, Wi-Fi or WLANThis section contains encryption and password settings. It's important not to confuse the Wi-Fi password with the router's settings password, although in modern firmware versions they may sometimes be the same by default.
Login to the router's web interface
To begin the process, open any browser on a device connected to the network. Enter your gateway's IP address in the address bar. If the default address isn't suitable, you can find it using the Windows command line by entering the command ipconfig, and find the line "Default gateway." After entering the address, press Enter, and the system will request authorization information.
In the window that opens, enter your login and password. For equipment issued ByFly, the combination is often used admin / admin or the data indicated on the sticker (for example, login admin and a unique password). Routers A1 They may have their own specific combinations, which should also be checked on the label. If you enter the information correctly but still can't log in, it's possible your browser has an old cache or an incorrect password.
In some cases, especially on older models ZTE or HuaweiThe interface may take a long time to load or require disabling VPN and proxy servers. Make sure extensions that block login page scripts are not enabled in your browser settings. After successful authorization, you will be redirected to the main control panel page, which displays your connection status and basic network information.
ByFly Hardware Manual (ZTE and Huawei)
Subscribers ByFly most often encounter equipment of brands ZTE And HuaweiThe interface of these devices has its own peculiarities, which are important to consider when changing your password. After logging in, find the tab Network or Net, and then select a subsection WLAN or Wireless networkThis is where the key security parameters are located.
In the WLAN settings menu you need to locate the item WPA PreSharedKey or PasswordIn the field SSID You can also change the name of your network, making it unique and not tied to an address or last name. For the encryption type, always select WPA2-PSK or WPA3, if the device supports this standard. Using an outdated protocol WEP or WPA Without numbers, your network becomes vulnerable to hacking in minutes.
After entering a new complex password, be sure to click the button Apply or SaveThe router may reboot the wireless module, and the connection will be interrupted. This is normal system behavior. In some firmware versions ZTE from ByFly There is a separate "Security" tab inside the WLAN section, where the field for changing the access key is hidden.
☑️ Checking ByFly settings
Dual-band routers, which broadcast two networks: 2.4 GHz and 5 GHz, are worth mentioning separately. In the interface, these can be displayed as separate subsections or as a single setting with the ability to be separated. It is recommended to set the same passwords for both bands, but different names (for example, HomeWiFi And HomeWiFi_5G) to clearly understand what frequency you are connected to.
Setting up A1 routers (Eltex and other brands)
Operator A1 actively uses the brand's equipment Eltex, as well as models from TP-Link And D-Link with branded firmware. The setup logic here is similar to the previous examples, but the menu item names may differ. After logging into your router's personal account, look for the section Wi-Fi or Wireless network in the top or side menu.
Inside the section, select the item Basic settings or SecurityHere you will see a field PSK encryption key or Password. Enter a new character combination. An important point for the equipment Eltex The "Apply" button at the bottom of the page is sometimes not immediately noticeable on smaller smartphone screens. Without clicking this button, the changes will not take effect.
If you have a router with guest network support (Guest Network), consider changing the password there as well. Guest networks are often left with factory settings or without a password at all, which creates a security hole. In interfaces A1 This section is usually located in the same Wi-Fi menu, but in a separate tab.
⚠️ Attention: A1 devices may have a "WPS" feature. For maximum security, it is recommended to disable this feature in the settings, as it allows connecting to Wi-Fi without entering a password, which is a known vulnerability.
After saving the settings on the routers A1 Often a complete reboot of the device via the menu is required System -> Rebootto ensure the new password works correctly on all connected clients. Don't skip this step if you notice network instability after changing the key.
What should you do if you forgot your router settings password?
If you've changed the administrator password and forgotten it, you won't be able to restore access programmatically. Find the Reset button on the router (often recessed), take a paperclip, and press and hold it for 10-15 seconds while the router is turned on. This will reset the device to factory settings, and the password will revert to the one on the sticker.
MikroTik setup specifics for advanced users
Routers are very popular in Belarus. MikroTik thanks to their reliability and flexibility, but their configuration is fundamentally different from consumer models. Control is carried out through a program WinBox or web interface. To change your Wi-Fi password, go to the section Wireless and double-click on the name of your access point (usually wlan1).
In the window that opens, go to the tab Wireless and find the field Security ProfileBy clicking the profile selection button, you will be taken to the security settings. It is here, in the tab Authentication, there is a field WPA Pre-Shared KeyChange it to a new password and click OK, then Apply.
Peculiarity MikroTik The problem is that changes are applied instantly, but may not be saved after a reboot unless you click the red save configuration button in the upper left corner of the interface or use the command /save in the terminal. This is a critical point that even experienced users forget.
/interface wireless security-profilesset [ find default=yes ] authentication-types=wpa2-psk mode=dynamic-keys \
supplicant-identity=MikroTik wpa-pre-shared-key="NewPassword" \
wpa2-pre-shared-key="NewPassword"
For those who prefer the terminal, the above command will allow you to quickly change your password through the console. However, the visual interface WinBox remains more visual for checking the status of connected clients and signal strength. Remember that in MikroTik You can set up separate firewall rules for your wireless network, restricting access to local resources.
Requirements for creating a strong password
Simply changing your password isn't enough; it must be crack-resistant. Modern brute-force attacks allow simple combinations to be discovered in seconds. A strong password should be at least 12 characters long and include uppercase and lowercase letters, numbers, and special characters. Avoid using dictionary words, birthdates, or sequences like 12345678.
Using special characters such as !, @, #, $, makes it much more difficult for hackers. However, make sure the characters you choose can be entered correctly on all your devices, especially if you have older equipment or smart home devices with limited input capabilities (for example, some TV models). Samsung or LG may not display special characters correctly).
| Password type | Example | Time to hack (approximately) | Recommendation |
|---|---|---|---|
| Weak | password123 | Instantly | Do not use |
| Average | Minsk2026 | A few hours | Not enough |
| Strong | K0t_B4s!k_Msk | Several years | Fine |
| Very strong | Tr0p!n@_7#Wi-Fi | Centuries | Optimal |
Write down new passwords in a safe place. Password managers such as Bitwarden or KeePass, do an excellent job of this task, generating and storing complex combinations. Don't store Wi-Fi passwords in text files on your computer desktop named "Passwords.txt"—that's the first place stealer viruses will look.
Common problems and their solutions
After changing the password, users often encounter problems with their devices connecting to the network. Windows may display the error "Couldn't connect to this network," while Android may display an "Authentication error." In 90% of cases, this can be resolved by deleting the network from the list of saved networks on the device and re-entering the password. The system attempts to use the old key, which causes a conflict.
Another common issue is a stuck DHCP client on the device. If the phone sees the network but doesn't receive an IP address, try rebooting the router after changing the settings. It's also worth checking if MAC address filtering is enabled. If this feature is enabled in the security settings, even with the correct password, a new (or reset) device won't gain access until its address is whitelisted.
In rare cases, especially on older routers D-Link or Trendnet, change the encryption type with WPA on WPA2 This may require a complete reset of network settings on the client device. If all else fails, reset the network settings on your smartphone or laptop. This will delete all saved Wi-Fi networks and Bluetooth pairings, but often resolves the compatibility issue.
⚠️ Attention: If after changing the password the internet stops working on all devices, but Wi-Fi still works, you may have accidentally changed the PPPoE or VLAN settings required for ISP access. In this case, check the WAN or Internet section of your router settings.
Provider interfaces may be updated, changing the layout of menu items. If you can't find the settings described above, refer to the manual for your specific router model or the manufacturer's website. Technical security implementation details may vary depending on the firmware version.
Is it possible to change the Wi-Fi password via phone?
Yes, this is possible. You need to connect to the router via Wi-Fi, open a browser on your phone, and enter the gateway address (usually 192.168.1.1). The rest of the process is identical to setting it up from a computer: enter the administrator username and password and find the Wireless/WLAN section.
What should I do if I forgot my router settings password (admin)?
If the default password (from the sticker) doesn't work, the only solution is to reset it using the Reset button. Press and hold it for 10-15 seconds while the router is turned on. This will reset the device to factory settings, and the password will be the one indicated on the sticker.
How often should I change my Wi-Fi password?
It is recommended to change your password every 3-6 months, or immediately if you suspect that someone else has connected to your network, or if you have given the password to guests who no longer need access.
Does a complex password affect internet speed?
No, password strength doesn't affect data transfer speed. Speed depends on your provider's plan, equipment quality, airborne interference, and the number of connected devices. WPA2/WPA3 encryption is hardware-based and doesn't create a noticeable load.
