Changing the password on your home Wi-Fi network is the first step you should take after connecting your equipment to a provider. The default combinations set by the manufacturer are often publicly available or too simple, making your network vulnerable to unauthorized access. Attackers can not only steal your traffic but also access personal files on connected devices.
In this article, we'll detail the process of changing the security key for MGTS subscribers using various equipment models. You'll learn how to access the router settings, where to find the necessary fields, and what parameters to set for maximum security. The procedure doesn't require in-depth technical knowledge, but it does require attention to detail.
No matter what kind of router you have, Sagemcom, Eltex or SercommThe basic operating principles remain the same. However, control panel interfaces may differ, so we'll cover the specifics of each model. Following these recommendations will help you secure the digital space of your home or office.
Preparing to change security settings
Before you begin changing the settings, you need to ensure a stable connection between your computer or smartphone and the router. It's best to perform this procedure through cable connection (LAN), as changing the Wi-Fi password will disconnect your wireless network. If this isn't possible, make sure you know the current password so you can reconnect after the change.
You'll also need to know the address to log into the admin panel. This is most often an IP address. 192.168.1.1 or domain name. To log in, you'll need the login and password for the router itself, which are often found on a sticker on the bottom of the device. If you've changed them before and forgot them, you may need to perform a factory reset.
☑️ Check before setup
It's important to have the device you'll use to enter the new password on hand. After saving the settings, all devices will be disabled, and you'll need to enter the new password on each one. Create a complex password in advance, using mixed-case letters, numbers, and special characters.
Login to the MGTS router web interface
Open any modern browser (Chrome, Firefox, Safari) on the connected device. In the address bar, where you usually enter the website address, you need to enter the IP address of your gateway. By default, MGTS equipment most often uses 192.168.1.1. Press the Enter key.
The system will request authorization. In the window that opens, enter your login and password. For most MGTS router models, the default login information looks like this: login - admin, password - admin or 1234. Exact data is always indicated on the information sticker located on the bottom of the device body.
⚠️ Note: If the default data doesn't work, it may have been changed by a previous user or the installation technician. In this case, you won't be able to log in without the new password, and you'll need to perform a full reset of the device using the Reset button.
After successful authorization, you'll be taken to the main page of the control panel. The interface may look different depending on the model, but the menu structure is generally the same. We're interested in the section responsible for wireless networking.
Instructions for Sagemcom routers
Equipment brand Sagemcom is one of the most common among MGTS subscribers. The interface of these devices is logically structured. After logging in, find the tab in the top or side menu. Local Network (Local area network) or immediately WLAN.
You need to go to the subsection Security (Security) or SSID SettingsThis is where the encryption parameters and access key are located. Make sure the correct security standard is selected. Currently, the most current and secure one is WPA2-PSK or WPA3, if your router supports it.
In the field Pre-Shared Key, Passphrase or WPA Key Enter a new password. The password must be at least 8 characters long, but longer combinations are recommended. Avoid using obvious information such as a phone number or date of birth.
Why might Sagemcom not save settings?
Sometimes Sagemcom routers require a reboot for changes to take effect. If the password hasn't changed after clicking "Apply" or "Save," try restarting the device via the "Maintenance" -> "Reboot" menu.
After entering the data, be sure to click the button Apply or Save at the bottom of the page. The system may warn you about a connection loss—this is normal. After a few minutes, the network will reappear with a new name (if you changed it) and will require a new key.
Setting up security on Eltex and Sercomm
Routers Eltex And Sercomm often have a more modern, but sometimes more confusing interface. In Eltex devices, look for the menu Wi-Fi or Wireless network in the left column. Next, select Basic settings or Security.
For models Sercomm the path may look like this Setup -> Wireless Setup -> Security SettingsIt is important to pay attention to the field here. WPA Pre-Shared KeyThis is where you enter your new secret phrase. The interface of these devices often requires confirmation of actions.
The peculiarity of these models is the presence of the function WPSIt is recommended to disable this feature in the corresponding menu, as it is a vulnerability that allows network passwords to be brute-forced. Even the most complex password can be compromised via WPS.
Don't forget to save your changes. In some Eltex firmware versions, the save button may be located at the very bottom of the page, and it may not be visible the first time—scroll to the bottom of the browser window. After applying the settings, the device may reboot automatically.
Encryption parameters and standard selection
When changing your password, choosing the right encryption algorithm is critical. It determines how easily an attacker can intercept your traffic or hack your network. Modern standards provide reliable protection, while older ones are long considered obsolete.
The table below provides a comparison of the main security standards available in MGTS routers:
| Standard | Security | Compatibility | Recommendation |
|---|---|---|---|
| WEP | Critically low | Old devices | Do not use |
| WPA (TKIP) | Low | Devices before 2010 | Not recommended |
| WPA2 (AES) | High | All modern devices | Recommended |
| WPA3 | Maximum | New devices (2018+) | Optimal |
Choose a mode WPA2-PSK (AES) or mixed WPA/WPA2, if you have very old gadgets. Mode WPA3 is the most advanced, but older smartphones and laptops may simply not see your network or be able to connect to it.
Creating a Strong Password: Expert Tips
Many users neglect password complexity by using simple sequences like 12345678 or passwordSuch combinations are selected by special programs in a split second. Your password must be resistant to this method. brute force (brute-force).
The ideal password formula includes:
- 🔹 Minimum 12 characters (the more, the better)
- 🔹 Uppercase and lowercase letters of the Latin alphabet
- 🔹 Numbers from 0 to 9
- 🔹 Special characters (for example: !, @, #, $, %)
Avoid using dictionary words, pet names, or family members' names. A good method is to use a mnemonic phrase: take the first sentence of a favorite song and replace some of the letters with numbers and symbols. For example, the phrase "In the forest a little Christmas tree was born" could become V1es_R0d#El0ch!.
⚠️ Important: Never store Wi-Fi passwords in plain text on your computer desktop or in unprotected phone notes. Use a password manager or write them down in a paper notebook kept in a safe place.
Common problems and their solutions
After changing the password, devices may not connect. This happens because the smartphone or laptop "remembers" the old network settings. You need to find your network in the list of available Wi-Fi networks, select "Forget network" or "Delete," and then reconnect using the new key.
Another problem is entering the settings at the address 192.168.1.1If the page doesn't load, check that DHCP is configured correctly to obtain an IP address automatically. Clearing your browser cache or using a different browser can sometimes help.
What should I do if my router stops distributing Wi-Fi?
If the Wi-Fi indicator on your router turns off or remains red after changing settings, you may have selected an incompatible region or channel. Try resetting the settings by pressing the Reset button (holding it for 10-15 seconds) and repeating the process, selecting automatic region settings.
If you've changed your password but your internet speed has dropped, check to see if your router has switched to the 802.11b/g standard instead of n/ac/ax. This can happen when manually changing some security settings. Reset the operating mode to Auto or Mixed.
FAQ: Frequently Asked Questions
Is it possible to change the MGTS Wi-Fi password through the app?
Yes, if your router supports remote management technology (TR-069) or your provider has its own app for subscribers (for example, "My MGTS" or similar). The app often has a "My Wi-Fi" section where you can change the network name and password without logging into the web interface.
I forgot my router admin password (not my Wi-Fi password). What should I do?
If you haven't changed the factory password, try the default combinations (admin/admin). If the password has been changed and lost, only a hard reset will help. Find the reset hole on the router case and press it with a paperclip for 10-15 seconds while the router is turned on. This will restore the factory settings, including the Wi-Fi password.
How often should I change my Wi-Fi password?
From a security standpoint, it's recommended to change your password every 3-6 months. However, if you use a truly complex password (20+ characters, randomly generated) and haven't shared it with guests, the need for frequent changes is reduced. The key is to change your password immediately if you suspect your neighbors are using your network.
Does changing your password affect your internet speed?
Changing the password itself doesn't affect speed. However, if you accidentally change the wireless channel to a busy one or switch the operating mode from 5 GHz to 2.4 GHz during setup, speed may drop. Make sure all other settings remain unchanged.
Do I need to reconnect all devices after changing?
Yes, absolutely all devices previously connected to your Wi-Fi network will lose connection. You'll have to manually enter the new password on every smartphone, tablet, laptop, and TV. This is an unavoidable process of updating credentials on clients.
