The setup process is carried out through the device's built-in web interface, accessible from any connected device. It's important to understand that changing the password in the router settings will disconnect all previously connected devices. You'll need to re-enter the new password on smartphones, laptops, and TVs to resume network access.
In this article, we will analyze in detail the algorithm of actions for the model ZTE F680We'll explore the nuances of the provider's interface and answer frequently asked questions.

Preparing to change security settings
Before making any changes to your equipment configuration, ensure the connection is stable. It's best to perform configuration from a device connected via cable. LANTo avoid connection interruptions when rebooting the Wi-Fi modules, use a smartphone or laptop connected to the current wireless network.
Make sure you have physical access to the router. On the back of the device ZTE F680 There's a sticker with factory data. It contains the login address, default username and password, and serial number. This information may be required if you haven't previously changed your admin panel login credentials.
⚠️ Please note: Changing your wireless network password will interrupt your internet connection for 10-20 seconds. It is not recommended to perform this procedure during important video conferences or online broadcasts.
It's also a good idea to create a strong access key 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 automated guessing by neighbors or hackers.
Logging into the ZTE router web interface
To begin setup, open any browser on your device. Enter the gateway's IP address in the address bar. For MGTS equipment, the standard address is 192.168.1.1In some cases, if the default address was previously changed, the current IP can be found in your computer's network connection settings.
After entering the address, the browser will ask for authorization. In the window that opens, enter your username and password. For most devices ZTE F680, issued by the provider, the standard data are:
- 🔑 Login:
admin - 🔑 Password:
admin(or indicated on the sticker under the device)
If the standard pair doesn't work, the settings may have been changed by the installers during installation. In this case, try a combination where the password matches the login, or use the data from the factory label. In extreme cases, you will need to reset the device to factory settings.
Find the wireless network section
Router interface ZTE The menu may vary slightly depending on the firmware version installed by MGTS. However, the menu layout remains the same. After successful authorization, you will be taken to the main status information page. Here, find the tab responsible for WLAN or Network settings.
In a classic menu, navigation usually looks like a tree structure on the left or horizontal tabs at the top. You need to go to the section Network (Network), then select the subsection WLAN (Wireless Network). Within this section, look for the item Security (Security) or SSID Settings (SSID settings).
Sometimes the provider hides advanced settings in "Expert" or "Advanced" mode. If you only see the basic status, look for the interface display mode switch. In some versions of the MGTS software, Wi-Fi settings are located in a separate tab. WLAN in the top menu without having to delve into the network's sub-items.
Wi-Fi Password Change Procedure
While in the security section (Security), you will see a field responsible for the access key. It may be called WPA Passphrase, Pre-Shared Key or simply Password. You must enter the new code you created in this field. Make sure your keyboard layout matches the required one (usually English).
Pay attention to the parameter WPA Encryption or Authentication TypeFor maximum security and compatibility with all modern devices, it is recommended to select the mode WPA2-PSK or mixed WPA/WPA2-PSKUsing an outdated standard WEP It is strongly not recommended as it is easily cracked.
After entering the new value, scroll down to the save button. It may be called Apply, Save or SubmitAfter pressing the router ZTE F680 Apply the changes. The wireless module may reboot, which will take a few seconds.
☑️ Verification after changing your password
Table of main settings
For ease of reference, the main parameters you'll find in the settings menu are summarized in the table below. This will help you navigate the interface.
| Parameter | Meaning / Description | Recommendation |
|---|---|---|
| SSID Name | Your wireless network name | Can be changed to anything understandable |
| Security Mode | Connection protection type | WPA2-PSK (AES) |
| WPA Passphrase | Access key (password) | Minimum 10 characters, letters and numbers |
| Channel | Broadcast channel | Auto or 1, 6, 11 (for 2.4 GHz) |
| Bandwidth | Channel width | 20/40 MHz (for 2.4 GHz), 80 MHz (for 5 GHz) |
Change channel (Channel) may be necessary if there are too many neighboring networks in an apartment building that create interference. If the internet is slow after changing the password, it might be worth experimenting with this setting by switching it from Auto to a specific free number.
Parameter Bandwidth affects the data transfer rate. For the 5 GHz band, which is also supported by the model ZTE F680The channel width is typically set to 80 MHz to achieve maximum speeds. However, in noisy environments, reducing this value can improve connection stability.
Dual-band networks: 2.4 GHz and 5 GHz
Router ZTE F680 is a dual-band device. This means it broadcasts two networks: one at 2.4 GHz and one at 5 GHz. They can be combined in the settings interface (function Band Steering) or divided into separate tabs, for example, WLAN 2.4G And WLAN 5G.
If you see a separate menu, you need to change the password for each band separately if you want them to match. Often, providers configure the same names and passwords for both bands for user convenience, but technically, these are two different access points within the same device.
The 5 GHz band offers higher speeds and is less susceptible to interference, but has a shorter range and is less able to penetrate walls. The 2.4 GHz band offers longer range but is slower. When changing your password, make sure you update the access keys for the frequencies you need, otherwise some devices may stop connecting.
Possible problems and their solutions
After changing the password, the device may fail to connect, displaying the error "Incorrect password" or "Connection failed." First, check your keyboard layout and letter case. Router security case-sensitive, that is, it distinguishes between uppercase and lowercase characters.
Another common issue is the DNS cache or network settings on the client device. The smartphone or laptop may "remember" old security settings. In this case, find your network in the list of available networks on the device, select "Forget Network," and reconnect using the new key.
⚠️ Note: The interface and menu layout may vary depending on the software version installed by your MGTS operator. If the items described here don't match, look for similar names or contact technical support.
If you have lost access to the web interface (forgot the administrator password), only a hard reset will help (Reset). There's a recessed hole on the back panel. Pressing the button inside with a knitting needle or paperclip for 10-15 seconds will reset the router to factory settings, including the password on the sticker.
Frequently Asked Questions (FAQ)
Where can I find the PIN code for connecting via WPS?
The PIN is usually found on the same sticker as the Wi-Fi password. It consists of 8 digits. However, using WPS is considered a less secure method, and many experts recommend disabling this feature in the router settings after the initial setup of devices.
Will my MGTS personal account password change?
No, the Wi-Fi router password and the password for the subscriber's personal account on the provider's website are different. You can change the key in the settings. ZTE F680 does not affect access to provider services and the billing system.
How often should I change my Wi-Fi password?
From a security perspective, it's recommended to change passwords every 3-6 months. However, for a home network with a strong key (15+ characters), it's sufficient to change it if you suspect unauthorized access or when purchasing new equipment.
What should I do if I lose internet access on all my devices after changing my password?
Most likely, a syntax error was entered or an incompatible encryption type was selected. Try temporarily resetting the old password. If this doesn't help, reset the router using the Reset button and set up the network again from scratch.
