Changing the password on your home Wi-Fi network is a standard procedure often required when purchasing a new router, after a factory reset, or simply for increased security. Owners of carrier-supplied equipment Beltelecom (trademark Byfly) can perform this operation without using a computer. Modern routers are equipped with a built-in web interface that displays correctly on smartphones and tablets.
The key to successfully completing the procedure is an active connection between your mobile device and the router. This means your phone must be connected to the Wi-Fi network you plan to configure, or to the device via a cable using an OTG adapter, although the wireless method is much more popular. If you lose network access, you'll need to use the button. Reset on the device body to restore factory settings, after which the standard password will be valid again.
In this article, we'll detail the process of changing the access key for the most common router models provided by your ISP. You'll learn how to log in to the admin panel, where to find the necessary fields, and which settings are best to protect against unauthorized access. These instructions are universal and suitable for most subscribers using equipment from these brands. ZTE, Huawei And TP-Link.
Preparing for Setup: What You Need to Know Before You Begin
Before changing your network configuration, you need to make sure you have all the necessary login information for your router's management system. Default login information is often found on a sticker located on the bottom of the device. There you'll find the IP address, as well as the default login and password. For equipment Byfly this is most often an address 192.168.1.1 or 192.168.0.1.
⚠️ Attention: If you change the password while connected to the Wi-Fi network you're reconfiguring, the connection to the router will be lost after the new settings are saved. You'll need to reconnect your phone using the new password.
Make sure your smartphone's mobile data is enabled if you plan to reconnect, or simply remember the new password. It's also a good idea to prepare a strong password in advance, consisting of letters and numbers, to prevent your neighbors from hacking your network. Weak passwords like "12345678" or your birthday are easily guessed by automated programs.
The setup process doesn't require installing any special software; any modern browser is sufficient. However, connection stability is critical: if the router freezes or the signal is too weak, the process may be interrupted. In such cases, it is recommended to move closer to the signal source or reboot the device before beginning.
Logging into the router's web interface from your phone
The first step is to log into your router's administrative control panel. Open any browser on your smartphone (Chrome, Safari, Opera) and enter the device's IP address in the address bar. Typically, for routers Byfly This 192.168.1.1If the page doesn't load, check that the numbers you entered are correct or try the address 192.168.0.1.
After navigating to the address, the system will request authorization. You will need to enter the administrator username and password. Don't confuse these with your Wi-Fi password! For most devices, Beltelecom standard credentials look like this admin / admin or admin / 1234Exact information can always be found on the factory label underneath the device.
The interface may vary depending on the model, but the logic remains the same. If you see a page with the operator or manufacturer's logo, you're on the right track. Some modern router models may offer a dedicated configuration app, but the web interface remains the most reliable and functional way to make changes.
☑️ Checklist before entering settings
Instructions for ZTE routers (F660, F670, F680)
Equipment brand ZTE is one of the most popular on the networks ByflyThe interface of these devices is quite logical, although it may seem overloaded with technical terms. After successful authorization, you need to find the tab responsible for wireless networks. It's usually called Network or WLAN.
In the menu on the left or in the top navigation bar, select the item WLAN, and then subsection Security (Security) or SSID SettingThis is where the fields for changing the network name (SSID) and encryption key are located. Find the field WPA Passphrase or Key - this is your current password.
Enter a new password in the appropriate field. Make sure the encryption type is set to WPA2-PSK or WPA/WPA2-PSK, as this ensures the best compatibility and security. Older protocols like WEP are not recommended, as they are easily cracked. After entering the information, be sure to press the button Submit or Save at the bottom of the page.
| Parameter | Recommended value | Description |
|---|---|---|
| SSID | Unique name | The name of your network that appears in searches |
| Security Mode | WPA2-PSK | The most secure encryption standard |
| WPA Passphrase | 8+ characters | Password for connecting devices |
| Channel | Auto / 1, 6, 11 | Signal transmission channel (preferably auto) |
What should I do if the Submit button doesn't work?
Sometimes the ZTE interface may freeze when saving. Try pressing the button again. If that doesn't help, refresh the page and re-enter the information. Make sure the password doesn't contain any restricted characters, although modern routers accept almost any characters.
Setting up Wi-Fi on Huawei and TP-Link routers
Routers Huawei And TP-Link, provided by the provider, have their own corporate interface style, but the operating principle is similar. In the menu Huawei you need to go to the section WLAN -> WLAN Basic Configuration or WLAN Security ConfigurationHere you will see a field WPA PreSharedKey, which needs to be changed.
For devices TP-Link (often found in the Archer series or older TL-WR models) the path may look like this Wireless -> Wireless SecurityThis section contains the field Wireless Password or PSK PasswordPlease enter the new code, making sure to use the correct case, as the system distinguishes between uppercase and lowercase characters.
It's important to note that on dual-band routers (supporting 2.4 GHz and 5 GHz), settings may be spread across different tabs. Check both bands if you want to ensure the password changes for all frequencies. Sometimes providers combine networks under a single name, but technically these are two separate access points.
⚠️ Attention: Router interfaces can be updated remotely by the provider. Menu locations and item names may differ slightly from those described. Search for keywords: Security, Wireless, WLAN, Key, Passphrase.
Common mistakes and how to solve them
One of the most common issues is the inability to save settings. This often occurs because the new password doesn't meet security requirements. For example, the minimum length is usually 8 characters. If you enter a shorter password, the system will return an error or simply ignore the command.
Another common situation is when a user forgets the new password immediately after changing it. In this case, the only solution is to physically reset the router. There's a small hole on the back panel. ResetYou need to press it with a paperclip and hold it there for about 10-15 seconds until the lights flash. The router will reset to factory settings, and the password will be the same as on the sticker.
There are also compatibility issues with older devices. If you set the encryption type too strong or use specific characters in the password, some gadgets (smart plugs, older phones) may stop seeing the network. In such cases, try simplifying the password, using only Latin letters and numbers.
Home Network Security Tips
Wi-Fi network security isn't just about a strong password. It's important to regularly update your router's firmware, if your provider allows it. Older firmware versions may contain vulnerabilities that allow attackers to bypass protection.
It is recommended to disable this function. WPS (Wi-Fi Protected Setup) if you don't use it. This feature is designed to quickly connect devices with the press of a button, but it is one of the weakest links in wireless network security. You can disable it in the WLAN -> WPS in the router settings.
Remember that your network can be used not only by phones but also by smart devices that rarely change their passwords. Changing your access key every six months is a good habit that minimizes the risk of traffic interception. If you notice an unknown device in your client list, change your password immediately and check your security settings.
Can I change my password if I'm not connected to Wi-Fi?
No, to enter the router settings (192.168.1.1) Your device must be within the local network.

Without connecting to the router, you cannot change its settings remotely over the internet (from another network) using standard tools.
What to do if the page 192.168.1.1 does not open?
Make sure you're connected to your router's Wi-Fi, not your mobile data. Try entering the address in Incognito mode. Also, check if you're using a VPN—it can block access to the local network. Try an alternative address. 192.168.0.1.
Did your internet connection reset after changing your Wi-Fi password?
No, the Wi-Fi password itself doesn't affect your ISP connection settings (the login and password for accessing the Byfly network). The internet will still work, but all devices will need to be reconnected with a new password. Internet access is only lost if you completely reset the router using the Reset button.
What is the hardest password to crack?
A strong password should contain at least 12 characters, including uppercase and lowercase letters, numbers, and special characters. Avoid dictionary words and keyboard sequences (e.g., qwerty). A random character set saved in a password manager is best.
