Changing your home Wi-Fi password is a basic, yet critical, procedure for ensuring the security of your personal data. Owners of equipment from Belarusian providers such as ByFly And Promsvyaz, often face the need to restrict internet access for strangers or simply want to set a more complex password after moving or purchasing a new device. The default factory settings, often printed on a sticker on the bottom of the device, are widely known and can be easily compromised by attackers, compromising the privacy of their traffic.
Changing the access key doesn't require extensive networking knowledge and only takes a few minutes if you know the correct procedure. All you need is a device connected to the router—a laptop, tablet, or smartphone—and access to the administrator's web interface. In this article, we'll cover all setup steps for the most popular router models, including ZTE, Huawei And TPLink, which are supplied to subscribers in bulk.
It's worth noting that firmware interfaces may differ slightly depending on the year of device manufacture and software version, but the general operating logic remains the same for all systems. Network security This depends directly on the complexity of your chosen password and the encryption protocol used. Ignoring these settings could result in your neighbors using your internet connection to download large amounts of data or, worse, to commit illegal online activities that the police could track using your IP address.
⚠️ Note: Web configuration interfaces may be updated remotely by your provider. If you don't see the menu items described below, check the help section on your provider's official website for up-to-date information or contact technical support.
Preparing for setup and logging into the router interface
The first and most important step is to ensure a stable connection between your computer or phone and the router. For configuration, it is highly recommended to use a wired connection via LAN cable, as changing the password and rebooting the router will disconnect the wireless connection, and you may lose access to the control panel without completing the procedure. If this is not possible, make sure your mobile device is connected to the Wi-Fi network for which you plan to change the password.
Next, open any web browser (Chrome, Opera, Firefox, Safari) and enter the router's IP address in the address bar. For the vast majority of devices provided by ByFly and Proms-bind providers, the default address is 192.168.1.1In some rare cases, especially on devices TP-Link or newer models ZTE, the address can be changed to 192.168.0.1 or a domain name, for example, tplinklogin.netThe exact address is always indicated on the information sticker located on the bottom of the router, next to the ports and buttons.
After entering the address, the system will request authorization. Here you will need the administrator login and password, which are also listed by default on the same sticker. The most commonly used combination is admin / admin or admin / a unique code from a set of characters. If you previously changed the password for entering settings and forgot it, you will need to perform a full reset of the device to factory settings using the button Reset, which will reset all settings, including the Wi-Fi network name and password, to their original values.
☑️ Check before entering settings
Changing the password on ZTE routers (F660, F670, F600)
Routers manufactured by the company ZTE are among the most common in the networks of ByFly and Promsvyaz operators. Their interface is functional, but can sometimes seem overwhelming for a beginner. After successfully logging into the system, you need to find the tab responsible for wireless networks. Depending on the firmware version, it may be called Network, WLAN or Wireless network. This section provides access to all radio module parameters.
Inside the WLAN menu we are interested in the subsection Security or SecurityThis is where the encryption and access key settings are located. Find the field labeled WPA Passphrase, Pre-Shared Key or Password. Enter a new character combination in this field. The password must be at least 8 characters long, but for true security, it's best to use 12 or more characters, combining uppercase and lowercase letters, numbers, and special characters.
An important point is the choice of encryption method. In the field Authentication Type or Defense version a protocol must be selected WPA2-PSK or, if the equipment is modern, WPA3Using an outdated standard WEP or WPA Without the number 2, the network becomes vulnerable to hacking in minutes, even by an inexperienced user. After entering the new password, be sure to click the button Submit, Apply or Savefor the changes to take effect.
What to do if the password field is inactive?
If you can't change your password in the ZTE security menu, check that the "Disable" box next to WPA is unchecked. Also, some ByFly firmware versions require you to first go to the "WLAN Basic" tab and ensure the SSID is set to "Enable." Without an active SSID, security settings may be locked for editing.
Configuring security on Huawei equipment
Routers Huawei, commonly found in Promsvyaz equipment lines, have their own recognizable interface, available in blue and white or green and gray. The setup logic is similar, but the menu layout differs. After logging in at 192.168.1.1 look for the tab WLAN in the top horizontal menu. A tree of subsections will open on the left side of the screen, where you need to select an item WLAN Basic Configuration or simply Basic.
In the window that opens, you'll see a list of wireless networks (SSIDs) if there are multiple (for example, a guest network and a main network). Select the network whose password you want to change. Below that is a field WPA PreSharedKey. Enter your new password here. Please note the parameter WPA Encryption mode: Make sure the value is selected AES, as this is the most secure encryption algorithm at the moment. Mode TKIP is considered obsolete and may reduce connection speed on modern devices.
Don't forget to scroll down the page after entering your data and click the button ApplyYour Huawei router may warn you that changing settings will cause the connection to be lost. This is a normal system response. If you're setting up a Wi-Fi network, you'll need to re-find your network in the list of available networks and enter a new password to connect. Cable users will remain connected if they haven't changed the LAN port settings.
⚠️ Note: Some Huawei models with firmware from providers may have hidden advanced settings. If you don't see the encryption type selection, try switching the interface to "Expert" or "Advanced" mode in the upper right corner of the page, if this option is available in your firmware version.
Changing the access key on TP-Link routers
Devices TP-Link They feature a user-friendly interface, often featuring an orange-green or blue-white color scheme. In newer firmware versions (with a green interface), navigation is via a vertical menu on the left. You need to find the section Wireless (Wireless mode) and then go to the subsection Wireless Security (Wireless Security). This is where all access control levers are concentrated.
In the central part of the screen, find the section WPA/WPA2 - PersonalThis is the recommended type of protection for home networks. In the field Wireless Password, PSK Password or Wireless network password Enter a new security combination. The system may require you to enter characters twice to confirm to prevent typos. You can also change the network name (SSID) here if you want your neighbors to see your router under a different name.
After filling in all the fields, click the button Save (Save). On TP-Link routers, changes are often applied instantly, but the device may prompt a reboot. In older interface versions (orange), you may need to go to the menu after saving. System Tools -> Reboot to activate the new settings. Do not skip this step if the network stops working correctly.
Recommendations for creating a strong password
Choosing a password isn't just a formality; it's the primary barrier to unauthorized access. Many users make the mistake of using simple sequences like 12345678, qwerty or your phone number. These combinations are automatically generated by programs in a split second. A strong password should be unique and not reused on other sites, so that if a data leak occurs on one site, your home network remains secure.
The optimal length for a Wi-Fi password is 12 to 20 characters. When creating a key, use mnemonic rules: take the base from a favorite phrase or song line and replace some letters with numbers or special characters. For example, the phrase "I like to drink coffee in the morning" could become Yl_p-k0_2026!This password is easy for the owner to remember, but practically impossible to crack using brute force.
It's also worth considering that some older devices (such as previous-generation gaming consoles or smart plugs) may not support special characters or have case-sensitive restrictions. If you have such devices, ensure the new password is compatible with them, or create a separate guest network with simplified requirements for IoT devices.
| Parameter | Weak defense | Average protection | High protection |
|---|---|---|---|
| Password length | 6-7 characters | 8-11 characters | 12+ characters |
| Character set | Just numbers | Numbers and letters | Numbers, letters, special characters |
| Protocol | WEP / Open | WPA (TKIP) | WPA2/WPA3 (AES) |
| Vulnerability | Hacking in seconds | Hacking in hours/days | Virtually unhackable |
Possible problems and solutions
When changing a password, users may encounter a number of technical difficulties. The most common issue is that the device won't connect to the network after changing the password. This often happens because the smartphone or laptop "remembers" the old access key and tries to log in with it. The solution is simple: find your network in the Wi-Fi list on the device, select "Forget network" or "Delete," and then reconnect using the new password.
Another situation: you cannot access the router settings. If the address 192.168.1.1 If the website isn't opening, check the IP addressing settings on your computer's network card. They should be set to automatic (DHCP) acquisition. The issue could also be caused by an antivirus or firewall blocking access to local IP addresses. Try temporarily disabling them or using a different browser.
If after changing the password, the internet connection is lost on all devices, although Wi-Fi is still available, you may have accidentally changed the encryption type to an incompatible one or made a mistake in other Wi-Fi settings. In this case, resetting the router using the reset button will help. Reset (Hold for 10-15 seconds while the power is on.) After this, the router will return to factory settings, and you will need to re-enter your ISP credentials (PPPoE or VLAN login and password) if they weren't automatically retrieved.
Frequently Asked Questions (FAQ)
What happens if I forget my new Wi-Fi password?
If you've forgotten your wireless network password but have a computer connected to the router via cable, you can view or change the password in the router's web interface (WLAN/Security section). If there are no wireless devices and the cable isn't connected, you'll have to reset the router using the Reset button and set it up again.
Is it possible to change the Wi-Fi password using an app on my phone?
Yes, many modern ByFly and Promsvyaz routers (especially ZTE and Huawei models) support management via mobile apps such as AiHome, Huawei AI Life, or proprietary provider apps. However, for initial setup and deeper security changes, web access via a browser remains the most reliable method.
Does changing your password affect your internet speed?
Changing your password itself doesn't affect speed. However, if you change the encryption type from WPA2 to the older WEP or leave the network without a password, speed may drop due to interference or unauthorized use of the channel by neighbors. Using the modern WPA2/WPA3 standard ensures optimal performance.
Should I change my password regularly?
For a home network, changing your password frequently (for example, once a month) isn't strictly necessary if you use a complex combination of characters and haven't shared it with strangers. However, if you suspect neighbors have connected to your network or you've been sharing your password with guests, changing the access key is the most effective security measure.
