How to change the password on a Tele2 Wi-Fi modem: instructions with pictures and tips

Forgot your home Wi-Fi password or want to set a more secure one? Modems Tele2 allow you to change your security key in just a few minutes—even if you've never logged into the admin panel before. In this article, we'll cover all ways to change your password: via a browser, mobile app, and if access is lost. We'll also explain which encryption type to choose to prevent neighbors from connecting to your network, and what to do if your modem won't save new settings.

The instruction is suitable for all Tele2 modem models, released since 2020: ZTE MF920V, Huawei B525, Tele2 Router T2-AC1750 and others. Even if you have a device from a different carrier but with Tele2 firmware (for example, after buying it second-hand), the steps remain the same. The main thing is to know IP address your router and login details for the admin panel (they can be found on the sticker on the back of the case).

We warn you in advance: after changing the password all connected devices will be disconnectedYou'll have to re-enter the new key on phones, laptops, and smart speakers. But at least you'll be sure no one has accessed your internet without permission.

1. Preparation: What you need to change your password

Before you access your modem settings, check three things:

  • 📶 Stable connection to the modemIt's best to use the cable (included) or connect via Wi-Fi from a device that already has the current password saved.
  • 💻 Device with a browserA laptop, tablet, or even a smartphone will do. The main thing is that it has Chrome, Firefox or any other modern browser.
  • 🔍 Admin login details. Usually it is admin/admin or tele2/tele2, but it’s better to put it on the sticker on the back of the modem (field Login/Password).

If you don't remember your admin panel password and the sticker has worn off, don't despair. In the section about reset settings We'll tell you how to restore access to your modem without losing your internet connection (in most cases).

⚠️ Attention: If your modem is rented from Tele2, do not change the network name (SSID) — this may violate the terms of the agreement. Password changes are permitted.

2. Login to the Tele2 modem control panel

To change your Wi-Fi password, you first need to access the modem's web interface. To do this:

  1. Open your browser and type in the address bar 192.168.0.1 or 192.168.1.1 (at Tele2 the first option is used more often). Click Enter.
  2. A login window will appear. Enter your login and password (see the sticker on the modem). If the information doesn't work, try these combinations:
    • admin / admin
    • tele2 / tele2
    • user / user
  • After successful login, you will see the main page with connection information.

    • If the page does not open, check:

    • 🔌 Is the cable connected to the modem and computer (if you are using a wired connection).
    • 🌐 Is the IP address entered correctly (sometimes letters O And 0 (they are confused).
    • 🔄 Restart your modem (unplug it from the power outlet for 30 seconds).
    What should I do if my modem's IP address has changed?

    If standard 192.168.0.1 or 192.168.1.1 If they don't work, you can find out the current address through the Windows command line: 

    ipconfig /all

    Look for the line Main gateway — this is your modem's IP address. On Mac or Linux, use the command ifconfig or ip route.

    3. Step-by-step instructions: how to change your Wi-Fi password

    Once you have logged into your control panel, follow these steps:

    ☑️ Change your Wi-Fi password

    Completed: 0 / 4
    1. Go to the Wi-Fi settings sectionDepending on the modem model, it may be called:
      • Wi-Fi → Security
      • Wireless → Wireless Security
      • Network settings → Wi-Fi password
  • Select encryption typeThe best option is WPA2-PSK (or WPA3-PSK, if the modem supports it). Never use WEP - this protocol can be cracked in a few minutes.
  • Enter a new password in the field PSK password (or Key, Passphrase). Password recommendations:
    • 🔐 Minimum length is 8 characters (preferably 12+).
    • 🅰️ Use mixed case letters, numbers, and symbols (!@#$%).
    • 🚫 Do not use personal information (date of birth, pet's name).
    • Save the settings. Click the button Apply, Save or SubmitThe modem will reboot (this is normal).

    After rebooting, reconnect to Wi-Fi using the new password. If the devices don't see the network, check if Wi-Fi has been disabled in the settings (section Basic or General).

    4. Which password to choose: security tips

    A weak Wi-Fi password is like an open door for hackers. According to Tele2, more than 30% of users use combinations like 12345678 or qwerty, which are hacked in seconds. To protect your network, follow these rules:

    Password type Example Security level Time to hack
    Simple (numbers) 12345678 🔴 Very low <1 minute
    Vocabulary (meaningful word) sunshine 🔴 Low 3-5 minutes
    Mixed (letters + numbers) Tele2WiFi2026 🟡 Average 2-3 hours
    Complex (symbols + case) T2#WiFi_Secure!26 🟢 Tall Years

    A good password should be:

    • 🔑 Long (from 12 characters).
    • 🎲 Random (not based on real words).
    • 🔄 Unique (do not use it for other services).

    You can use a password generator (for example, one built into your browser) Chrome or Firefox) or come up with your own using the phrase method:

    Cat! Loves. Milk? In_2026! → K!L.M?V_26!

    This password is easy to remember but difficult to guess.

    5. Forgot your admin password? Reset your Tele2 modem to factory settings.

    If you can't log into the control panel (you forgot your login/password or the previous owner changed them), you will have to do hard reset — Factory reset. Note: After this All Internet and Wi-Fi settings will be reset, including:

    • 📡 Network name (SSID) and Wi-Fi password.
    • 🔧 Connection settings to Tele2 (reactivation of the SIM card may be required).
    • 🔒 Admin panel password (will become default, see sticker).

    To reset your modem:

    1. Find the button on the back panel Reset (sometimes it is recessed into the body).
    2. Take a paper clip or a toothpick and press and hold the button 10-15 secondsuntil the indicators start flashing.
    3. Release the button and wait for the reboot (1-2 minutes).

    After reset:

    1. Connect to the Wi-Fi with the default name (indicated on the sticker).
    2. The Wi-Fi password will also be the default one (usually 12345678 or the last 8 digits of the serial number).
    3. Log in to the admin panel following the instructions from Section 2 and set up the Internet again (data for connecting to Tele2 will come via SMS after SIM activation).
    ⚠️ Attention: On some models (Huawei B525, ZTE MF920V) reset button Reset Tele2 settings won't reset. In this case, you'll have to call the operator's support (📞 611 from a Tele2 phone) and ask to reset the configuration remotely.
