How to change the password on a ZTE F670 Rostelecom Wi-Fi router

Securing your home network starts with setting up a strong wireless access key. ZTE F670, which is often issued to subscribers by the provider Rostelecom, has default settings known to a wide range of users. This makes the network vulnerable to unauthorized connections unless the factory settings are changed immediately after installation.

Changing your password takes just a few minutes, but significantly increases the security of your personal data. In this article, we'll cover logging into the web interface, navigating the menu, and properly configuring encryption settings for the F670.

It's important to understand that after changing the access key, all connected devices will require re-authorization. Therefore, it's recommended to perform this procedure when you have physical access to the router or the ability to quickly reconnect devices via cable.

Preparing to change security settings

Before you begin editing settings, ensure a stable connection between your computer or smartphone and the router. It's best to configure the settings via a wired connection. Ethernet, as this will eliminate the risk of connection loss while saving changes. However, if this isn't possible, you can use your current Wi-Fi connection, although this is less reliable.

You will need your login credentials to access the admin panel. On the bottom panel of the device ZTE F670 There is usually a sticker with the factory login and password. For equipment Rostelecom Standard combinations are often used, but they can be changed by the wizard during installation.

  • 🔌 Connect your computer to the router with a network cable or make sure you have a Wi-Fi signal.
  • 📝 Find the sticker on the bottom of the device and write down the authorization data (Username and Password).
  • 🌐 Open any browser and get ready to enter the gateway address in the address bar.

If the default data doesn't work, the password may have been changed previously. In this case, a full factory reset will be required, which will return all settings to their original state, including the network name and access key.

⚠️ Note: If you change settings remotely via Wi-Fi, please be aware that after applying the new password, the connection will be immediately disconnected. You will have to re-search for the network and enter the new information.

Logging into the router's web interface

Open your installed browser and enter the device's IP address in the address bar. For most models ZTE F670, used by the provider Rostelecom, the standard address is 192.168.1.1In some cases, especially on older firmware or specific configurations, the address may differ, for example, 192.168.0.1.

After entering the address, press Enter. If the connection is established correctly, the browser will ask for authorization. In the window that appears, enter your username and password. The default pair is often admin / admin or user / user, but always check the sticker on the case.

What to do if the page does not load?

If your browser says "Unable to access the site," check that you've entered the IP address correctly. Make sure your computer's network card is configured to obtain an IP address automatically (DHCP). Also, try disabling your smartphone's mobile data connection, if configured through it, so that traffic only goes through your Wi-Fi router.

A successful login will open the control panel's main menu. The interface may be in English or Russian, depending on the firmware version installed by the operator. The menu structure is generally logical, but requires careful selection of sections.

Navigating the WLAN settings menu

After logging in, you'll find yourself on the main status page. We need to find the section responsible for wireless networks. In the interface ZTE it is often referred to as Network (Network) or immediately placed in the side menu as WLAN.

Expand the tab Network and find the subsection WLANWithin this section there may be various tabs, such as "Basic," "Security," and "WPS." We're specifically interested in the tab Security (Security), where the password settings are located.

In some firmware versions the path may look different: AdvancedWLANSecurityIf you see a list of networks (SSIDs), select the one whose name matches the name of your network (usually SSID1 or SSID5 for 5 GHz).

It's important not to confuse the Guest Network settings with the main ones. Make sure you're editing the settings for the access point to which your main devices are connected.

Setting a new password and choosing encryption

In the security section you will see a field WPA Pre-Shared Key or simply PassphraseThis is where your current password is stored. Delete the old characters and enter a new key. The password must be between 8 and 63 characters long.

A critical parameter is the encryption type. In the field Authentication Type or Security Mode you need to choose WPA2-PSK or WPA/WPA2-PSKThese are the most reliable standards currently available, providing protection against simple data interception.

The Encryption mode must be set to AES. Option TKIP is considered less secure and may limit connection speed on modern devices.

  • 🔐 In the password field, use a combination of letters (upper and lower case), numbers, and special characters.
  • 🛡️ Make sure the security type is selected WPA2-PSK.
  • ⚙️ Set the encryption method to AES.

Once you've entered all the information, don't close the page yet. You'll need to apply the changes first by clicking the button. Submit or Apply at the bottom of the page.

Save configuration and reboot

After clicking the Apply Settings button, the router ZTE F670 will begin processing the new parameters. At this point, a brief connection interruption may occur. The system may prompt you to immediately reboot the device for the changes to take effect.

If the automatic reboot does not occur, it is recommended to perform it manually. Go to the section Maintenance (Service) or System Tools and select the option RebootThis will ensure that the wireless module configuration is updated.

During the reboot process, the indicators on the front panel of the router may blink or go out. This is normal behavior and indicates that the device's operating system is loading.

⚠️ Caution: Do not unplug the router during the reboot or configuration update process. Interrupting the writing of system files may damage the device's software.

After the device has fully booted up (usually takes 1-2 minutes), the indicator WLAN or Wi-Fi should light up or start flashing, indicating that the network is ready for operation.

Connecting devices with a new key

Now that the settings are saved, you need to update the connection settings on all your devices. Smartphones, tablets, and laptops will attempt to connect with the old password, which will result in an authorization error.

On your device, find your network in the list of available Wi-Fi networks. Tap it and select "Forget network" or "Delete profile." This will remove the old saved key from the device's memory.

Then scan for networks again, select your access point, and enter a new password. Be careful when entering your password: the system is case-sensitive, so Admin And admin - these are different passwords.
