Changing your wireless network password is the first step you should take after installing new equipment or if you suspect unauthorized access to your network. In the case of equipment Eltex, which is often used by providers to provide triple-play services, the network security procedure has its own peculiarities that distinguish it from setting up mass-market household routers. Properly installed encryption key ensures that your data remains confidential and your internet speed won't be affected by unauthorized users.
Many users face difficulties when trying to change the default settings, as the interface ONT-terminals or GPONRouter security may be hidden or simplified by your provider. However, with the necessary access rights and an understanding of the web configurator's logic, you can independently manage your local network's security settings. In this article, we'll cover the authorization process, menu navigation, and setting a secure password for the protocol. WPA2-PSK.
Before making changes, it's important to ensure your device is connected to the router either via cable or wirelessly. This will prevent connection loss while applying new settings. We'll cover both standard setup scenarios and situations where a factory reset is required to regain full control of the device. Eltex.
Preparing to change security settings
The first step is a physical connection to the device. For initial setup or changing critical security settings, a wired connection is highly recommended. EthernetThis will ensure a stable connection that won't be interrupted when the WiFi module reboots. You'll need a patch cord, which usually comes with the equipment, or any other serviceable cable of the category CAT5e and above.
Plug one end of the cable into the port LAN1 (or any other LAN port, if there are several) on the back panel of the router Eltex, and the second one - into the network card of your computer or laptop. If you plan to configure it via WiFi, make sure you know the current password for your wireless network, as you will need to reconnect after changing the settings. You will also need the login details for the web interface: IP address, administrator login and password.
⚠️ Note: If your equipment was provided by your ISP, the default login credentials can be changed remotely. In this case, manually changing the WiFi password may not be possible without resetting the settings, which will delete internet access settings (PPPoE, VLAN, etc.).
Check the indicators on the front panel of the device. Is the indicator light on? LAN? Does it blink when transmitting data? If the indicator is green or yellow, physical contact has been established successfully. Now you can move on to the software part of the setup. Make sure that the network adapter properties on your computer are set to automatic acquisition. IP addresses (TCP/IP protocol version 4).
☑️ Check before setup
Logging into the Eltex router web interface
To manage router settings Eltex The built-in web server is used. Open any modern browser: Google Chrome, Mozilla Firefox, Yandex Browser or Microsoft EdgeIn the address bar, where you usually enter the website address, you need to enter the IP address of the device. The most common addresses for equipment Eltex: 192.168.0.1, 192.168.1.1 or 192.168.100.1The exact address is often indicated on a sticker on the bottom of the device next to the barcode.
After entering the address and pressing the key Enter The browser will request authorization. A window will appear asking you to enter your username and password. For most models Eltex (for example, series NTP-RE or WOP) by default the following are used:
- 🔑 Login:
admin - 🔑 Password:
adminor1234
In some cases, especially at terminals GPON, login can be user with limited access rights, or admin with a password unique to each device (indicated on the sticker as Password or Pwd). If the default combinations don't work, your provider may have changed them remotely. In this case, you won't be able to log in without a factory reset.
What should I do if the page doesn't load?
If your browser says "Unable to access the site," check if you're using a proxy server or VPN. Try opening the site in incognito mode. Also, make sure your computer is on the same subnet as your router (for example, if your router is 192.168.0.1, your computer should have an address like 192.168.0.X).
After successful authorization, you will be taken to the main system status page. This displays the uptime, firmware version, and port status. The interface may vary depending on the model (WOP-100, WOP-200, NTP-RE), but the menu layout remains the same. We need to find the section responsible for wireless networking.
Find the Wireless Network (WLAN) section
Router interface Eltex It's structured logically. The main menu is located at the top or left side of the screen. Look for the tab titled WLAN, Wireless, WiFi or Wireless networkIn some firmware versions, security settings are placed in a separate submenu, which may be called Security or WLAN Security.
It is common to split the settings into several profiles or SSID (network name). The router can broadcast several networks simultaneously: the main network, the guest network, and the IPTV network. You need to select the profile that matches your main network. This is usually SSID1 or the profile with the name you see when searching for WiFi on your phone. Be careful: changing the password in the profile Guest will not change the password for your main network.
| Parameter | Description | Recommended value |
|---|---|---|
| SSID Name | The name of the wireless network visible in the list of available networks | Any, without special characters |
| SSID Enable | Enables or disables network broadcasting | Enabled |
| Security Mode | Data encryption type | WPA2-PSK / WPA3 |
| WPA Pre-Shared Key | The password itself for connection | Minimum 8 characters |
If you can't find the settings you need, your interface may be in Basic (Basic). Try switching to the mode Advanced (Extended) or Expert, if available, in the upper right corner of the screen. This will give you access to all technical configuration parameters.
Setting up encryption type and password
Inside the WiFi settings section, you'll see a field that controls the authentication method. It may be called Authentication Type, Security Mode or EncryptionTo ensure maximum compatibility with all modern devices (smartphones, laptops, smart home) and a high level of protection, you should choose a standard WPA2-PSK (or WPA2-Personal).
Older standard WEP It is strictly forbidden to use it - it can be hacked in a few minutes even by an inexperienced user. Standard WPA3 is the most modern, but older devices may not see your network or be able to connect. If the list includes a combined option WPA/WPA2-PSK, select it for best compatibility.
The main field we are interested in is called WPA Pre-Shared Key, Passphrase, Wireless Password or simply PasswordThis is where you'll need to enter your new character combination. When creating a password, follow these security guidelines:
- 🛡️ Use at least 10-12 characters.
- 🛡️ Combine uppercase and lowercase letters, numbers, and special characters (if the interface allows).
- 🛡️ Avoid obvious combinations like birth date or sequence
12345678.
⚠️ Attention: Some older versions of Eltex firmware may not handle special characters correctly (for example,
#,&,") in the WiFi password. If your devices stop connecting after saving the settings, try using only letters and numbers.
After entering your password in the appropriate field, don't rush to close the page. Check if the button is there. Apply (Apply) or Save (Save). In some interfaces, changes take effect only after clicking this button. Sometimes, an additional device reboot via the menu is required. System Tools -> Reboot.
Save configuration and reboot
Once you've entered a new password and selected the encryption type, you need to commit the changes. Click the button Save/ApplyThe system may warn you that the wireless module will be restarted. This is normal: current WiFi connections will be lost, and the router will begin broadcasting a network with new security settings.
If you configured the router via WiFi, your device (laptop or phone) will lose the connection immediately after applying the settings. You'll need to go to the list of available networks, find your SSID (network name), and enter a new password. If the connection is successful and the internet is restored, then the procedure was completed correctly.
It's important not only to change the settings in RAM, but also to save them to the device's permanent memory. In the interfaces Eltex there is often a separate button Save Config or Export Configuration, but usually applying the settings in the WiFi menu automatically triggers saving. However, to be sure, you can go to the section Maintenance or System and find the item Save & Reboot.
If after rebooting the settings are reset to the old ones, it is possible that the device is controlled by the provider (protocol TR-069). In this case, the provider may automatically reset its settings each time you connect to the network. This can only be resolved by disabling remote management in the appropriate section or by contacting technical support.
What to do if settings are not saved
The situation when the router Eltex A router stubbornly refuses to save a new password is uncommon, but possible. One possible cause is a full event log or a device file system error. In this case, a full reboot helps: unplug the router, wait 10-15 seconds, and plug it back in. Then try changing the password again.
Another common issue is the browser cache. The router's web interface may display an outdated version of the page. Try opening the settings in incognito mode or clearing the browser cache. You can also try accessing the interface from a different device or using a different browser.
If nothing helps, there is a radical method left - a factory reset (Factory Reset). There is a small hole with the inscription on the router body. Reset or RSTWith the power on, press it with a paperclip and hold it there for 10-15 seconds until the lights blink simultaneously. After this, the router will return to its out-of-the-box state, and you'll need to reconfigure your internet connection (if your ISP doesn't configure it automatically).
⚠️ Note: A factory reset will erase all user data, including PPPoE settings, VLAN, and static IP addresses if they were configured manually. Make sure you have your ISP contract detailing these settings before performing a factory reset.
Frequently Asked Questions (FAQ)
Where can I find the WiFi password sticker on my Eltex router?
The sticker is usually located on the bottom of the device. Look for the field WPA Key, Wireless Password or PWDIf the sticker has worn off, you can view the password in the web interface under WLAN if you are already connected to the router via cable.
Is it possible to change the password via the mobile app?
Eltex home routers generally don't have official mobile apps for configuring them. Configuration is performed exclusively through a web browser. Some providers may offer their own service management apps that include the ability to change the WiFi password, but this varies by carrier.
Why doesn't my TV connect to WiFi after changing the password?
It's likely that your TV still has an old network profile. Go to your TV's network settings, find your network, select "Forget Network" or "Delete," then search again and enter a new password. Also, check that you're not using special characters that your TV may not support.
How often should I change my WiFi password?
At home, it's sufficient to change your password once a year or if you suspect a breach. In an office environment, it's recommended to change access keys every three months and use more complex authentication algorithms, such as WPA-Enterprise.
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 outdated WEP or WPA(TKIP), the speed may drop to 54 Mbps. Always choose AES encryption for maximum performance.
