Changing your home Wi-Fi password is one of the most frequently requested procedures for ByFly subscribers. It's often necessary to restrict unauthorized access to your network or simply update security information after installing new equipment. This can be done without a computer, directly from a smartphone or tablet connected to the wireless network.
In this article, we'll take a detailed look at how to log into your router's web interface from a mobile device. You'll learn how to find the gateway address and what default credentials are used for authorization. ZTE, Huawei or TP-Link, as well as which parameters are best to choose for maximum protection of your home network.
The setup process doesn't require any special technical knowledge, but it's important to follow the steps carefully. Incorrectly selecting the encryption type or password length can cause some older devices to stop connecting to the internet. Carefully follow the steps below to ensure stable operation of your Wi-Fi.
Preparing your mobile device for setup
Before changing your router's configuration, make sure your smartphone or tablet has an active connection to the network you plan to change. If you're connected via 4G/5G mobile data, you won't be able to access the router's control panel, as the devices are on different network segments.
Open your device's Wi-Fi settings and find your network name (SSID). It's usually listed on a sticker on the bottom of the router and looks like this: ByFly_XXXX or ZTE_XXXXOnce connected, make sure your internet connection is working properly and remember your current password if you plan to share it with other users later.
It's also a good idea to prepare a new, complex password in advance. It should contain at least eight characters, including upper- and lower-case letters and numbers. Using simple combinations like "12345678" or your date of birth makes your network vulnerable to brute-force attacks. Write down the new access key in a note or use a password manager.
⚠️ Attention: If you're changing settings remotely (away from home), keep in mind that after changing the Wi-Fi password, your phone will lose connection to the router. To continue browsing the internet, you'll need to re-enter the new password in the Wi-Fi settings.
Find your router's IP address and access the control panel
Each router has a unique IP address through which its settings are managed. For devices provided by the ByFly provider, the most common address is 192.168.1.1 or 192.168.0.1However, in some models, especially in newer versions ZTE or Huawei, the address can be used 192.168.100.1.
To find the exact gateway address without guessing, you can use your smartphone's functionality. On Android, go to Wi-Fi settings, tap the name of the connected network, and select "Details" or "Manage." The required IP address will be listed in the "Gateway" or "Router" field.
iOS users (iPhone, iPad) need to go to Settings → Wi-Fi, click the blue information icon (the letter "i" in a circle) next to the network name. In the menu that opens, find the line "Router." This is the address you'll need to enter into the address bar of your browser (Chrome, Safari, or Yandex Browser).
After entering the address in the browser's address bar, the authorization page will open. The system will request a username and password to access the administrative panel. This information is often the same as the Wi-Fi access details, but may differ. Standard combinations for Beltelecom equipment are listed in the table below.
| Router model | IP address | Login (User) | Password |
|---|---|---|---|
| ZTE (F660, F670) | 192.168.1.1 | admin | admin |
| Huawei (HG8245, HG8247) | 192.168.100.1 | root | admin |
| TP-Link (TD-W8961N) | 192.168.1.1 | admin | admin |
| D-Link (DIR-300, 615) | 192.168.0.1 | admin | (empty) |
Authorization in the router web interface
Entering your credentials is a critical step. If you're using a default login and password that you've never changed, there shouldn't be any issues. However, if you or a technician has previously changed the security settings and the data has been lost, a full factory reset of the device will be required.
Interfaces vary significantly between different manufacturers. In routers ZTE A two-tier access system is common: a standard user and an administrator. In most cases, standard user access is sufficient for changing the Wi-Fi password, but for more detailed channel customization, administrator access is recommended.
If the standard "admin/admin" pair doesn't work, try checking the information on the sticker underneath the device. It often lists "User" and "Password" specifically for the web interface, which may differ from the WPA PIN used for the wireless connection.
What should I do if I don't know the password for the web interface?
If the default passwords don't work and you haven't changed them yourself, it's possible the password was changed by the technician during setup. In this case, the only solution is to reset the router using the Reset button on the back of the router. Press it with a paperclip for 10-15 seconds while the power is on. The router will reboot with factory settings, and the password will be the same as on the sticker.
After successfully entering your data, you'll be taken to the main control panel page. This displays the connection status, device uptime, and current channel load. Menu navigation can be horizontal or vertical, depending on the firmware version.
Setting up a wireless network on ZTE routers
Equipment brand ZTE is the most popular among ByFly subscribers. The interface of these devices is typically blue and white. To change the password, go to the Network (Network), then select WLAN (Wireless network) and beyond Security (Safety).
In the menu that opens, find the field WPA Passphrase or Pre-Shared KeyThis is where you enter the access key. Delete the old characters and enter a new combination. It's important to make sure that the field Authentication Type value selected WPA2-PSK or WPA/WPA2-PSKThis will ensure compatibility with all modern gadgets.
Don't forget to also check the network name (SSID Name) in the adjacent tab. BasicIf you want to hide your network from prying eyes, you can disable SSID broadcasting, but then you'll have to connect new devices manually by entering the network name.
☑️ Checking ZTE settings
After making changes, be sure to click the button Submit or Apply At the bottom of the page. The router may warn you that the wireless connection will be lost. This is normal: the device is rebooting the Wi-Fi module with the new settings.
Changing WiFi Password on Huawei Devices
Routers Huawei, often used for GPON terminals, have their own specific interface. The settings menu is usually located at the top of the screen. You need to find the section WLAN or Basic, and then go to the subsection WLAN Security Configuration.
The key parameter here is WPA PreSharedKeyIn some firmware versions, this field may simply be called "Passphrase." Enter your desired password, adhering to the length requirements (usually 8 to 63 characters).
Pay special attention to the parameter WPA Encryption ModeIt is recommended to select the mode TKIP & AES or simply AES. Mode TKIP It is considered outdated and less secure, and its use may limit connection speed on modern smartphones.
⚠️ Attention: On some Huawei models, the interface may be divided into profiles (SSID Profiles). Make sure you're editing the settings for the main profile (usually Profile 1), not the guest network, if one is configured separately.
Saving the settings is done by pressing the button ApplyAfter this, the router will apply the changes. If you're setting up the device via Wi-Fi, reconnection will occur automatically after a short delay, but sometimes you'll need to manually reselect the network from the list of available connections.
Instructions for TP-Link and D-Link routers
Although ByFly primarily supplies ZTE and Huawei equipment, it also has devices in circulation TP-Link And D-LinkIn TP-Link routers (green interface), the settings path looks like this: Wireless → Wireless SecurityHere you need to select the type of protection WPA/WPA2 - Personal (Recommended) and enter the password in the field Wireless Password.
For D-Link devices, the interface is often orange and gray. You will need the section Setup, then subsection Wireless SettingsThere is a button at the bottom of the page. Manual Network Connection Setup, leading to advanced security settings.
In both cases, the principle remains the same: find the wireless network section, select the WPA2 encryption type, and enter a new phrase. After saving the settings (button Save Settings or Save) The router may prompt you to reboot. Accept this for the changes to take effect correctly.
Selecting optimal security parameters and frequencies
Simply changing your password is only half the battle. For stable operation, it's important to choose the right encryption standards. Currently, the "gold standard" is WPA2-PSK (AES)The older WEP method can be cracked in minutes, and the newer WPA3 is not yet supported by all devices.
It's also worth paying attention to the frequency range. If your router is dual-band, it broadcasts two networks: 2.4 GHz and 5 GHz. You can set the same password for both, but it's better to give them different names (for example, Home_WiFi And Home_WiFi_5G) to understand what frequency you are connected to.
The 2.4 GHz frequency has better wall penetration, but is often congested by neighbors' routers and microwaves. The 5 GHz frequency offers high speeds but is less effective at penetrating obstacles. For smartphones and laptops within a single room, 5 GHz is ideal, while 2.4 GHz is ideal for smart lights and vacuum cleaners.
Why can't I set a password shorter than 8 characters?
The WPA2 protocol technically doesn't allow for a password shorter than 8 characters. However, even 8 characters is too few for modern cryptography. It's recommended to use 12 or more characters, including special characters, to ensure that brute-force attempts take years.
Possible problems and solutions
After changing your password, you may encounter a situation where your phone displays "Connection Error" or "Incorrect Password," even though you're sure you've entered it correctly. This is often because the device is attempting to connect using old saved data. There's only one solution: "Forget the network" in your phone's Wi-Fi settings and reconnect.
Another common issue is encoding incompatibility. If you use rare characters or characters from other alphabets in your password, some devices (especially game consoles or older TVs) may interpret them incorrectly. Use only Latin characters (English letters) and numbers to avoid conflicts.
If your router stops distributing internet after changing settings, check whether PPPoE or VLAN settings have been reset. Changing your Wi-Fi password typically doesn't affect your connection settings, but human error cannot be ruled out. Make sure the router's indicator lights are lit correctly.
⚠️ Attention: Router interfaces and firmware are regularly updated. Menu locations and item names may differ from those described in the instructions. If you can't find the item you need, check the official documentation on the manufacturer's website or in your subscriber account.
Frequently Asked Questions (FAQ)
Can I change my Wi-Fi password if I'm not connected to the network?
No, the device must be connected to the router to access its settings (web interface). You can use a LAN (Ethernet) cable to connect a laptop or phone (via an OTG adapter) directly to the router, but a wireless connection to the network is required to access the control panel via a browser.
What should I do if I forgot the password for my router's web interface?
If you changed the settings password (admin) and forgot it, it can't be recovered. The only solution is to reset the router to factory settings. This will reset the login and password to the ones on the sticker on the bottom of the device, but all other settings (connection type, network name) will also be reset.
Should I change my Wi-Fi password regularly?
From a security perspective, changing your password regularly (for example, every 3-6 months) is a good practice, especially if you've had a lot of guests or suspect your neighbors are using your internet. However, for a typical home network, setting a single, very complex password during initial setup is sufficient.
Does changing your password affect your internet speed?
Changing your password itself doesn't affect speed. However, if you changed the broadcast channel or encryption standard (for example, from AES to TKIP) during setup, your speed may change. Also, if you had a lot of rogue users connecting to your network, disconnecting them after changing your password can significantly increase your connection speed.
