  • 📡 For classic models (TL-WR840N, Archer C20): go to Wireless → Wireless Security.
  • 🌐 For new routers (Archer AX55, Deco X60): select Advanced → Network → Wi-Fi.
  • 🔄 For dual-band models (Archer C5400): Set up a password separately for networks 2.4 GHz And 5 GHz.

Now follow the instructions:

  1. In the field Network name (SSID) You can keep the old name or come up with a new one (for example, MyHomeWiFi_5G).

  2. In the field Password or Network Key Enter a new password. It must contain:

    • ✅ Minimum 8 characters (optimally 12+).
    • ✅ Combination of uppercase and lowercase letters (AaBbCc).
    • ✅ Numbers (123) and special characters (!@#$).
  • In the field Security Type select WPA2-PSK or WPA3-PSK (if supported). Never use outdated WEP - it can be cracked in minutes!

  • Save the changes by clicking the button Save or ApplyThe router will reboot (takes 1–2 minutes).

  • After rebooting, all devices will be disconnected from Wi-Fi. Please reconnect them using the new password.

    Make sure the Network Name field is not empty|

    Security type selected: WPA2/WPA3|

    All devices are ready to reconnect-->

    If you can't access your router settings because you've lost your password, the only way is to hard reset Factory reset. This procedure will return all settings to their out-of-the-box state, including the Wi-Fi name and password.

    2. Take a paper clip or a toothpick and press and hold the button 10-15 secondsuntil the indicators on the front panel start flashing.

    3. Release the button and wait for the reboot (1-2 minutes).

    4. After reset:

      • 🔄 The Wi-Fi name and password will return to the factory settings (indicated on the router sticker).
      • 🔐 The password for accessing the control panel will be reset again admin.
      • ⚠️ All personal settings (including guest network, parental controls, and device priorities) will be deleted.
      ⚠️ Attention: On some models (Deco, Archer AX) The reset results in the router being unlinked from the cloud account. TP-LinkTo restore remote access, you will need to re-link it through the app. Tether.
      What to do if the Reset button does not work?

      If the router does not reset after holding the Reset button, try:

      5. Common mistakes when changing your password and how to avoid them

      Even experienced users sometimes encounter problems after changing their Wi-Fi password. Here are the most common errors and their solutions:

      Error Cause Solution
      After changing the password, the Internet disappeared. The security type is incorrect or the password contains invalid characters (e.g. Cyrillic) Go back to settings and select WPA2-PSKThe password must contain only Latin characters, numbers, and symbols. !@#$%^&*
      Devices do not connect to Wi-Fi The password is too complex (more than 32 characters) or the MAC address filter is enabled Simplify your password or disable filtering in the section Wireless MAC Filtering
      The router constantly reboots Settings conflict after changing the password (relevant for older firmware versions) Perform a factory reset and reconfigure your router.

      Another common problem is different passwords for 2.4 GHz and 5 GHzIf your router supports both bands, make sure you've changed the password for both networks. Otherwise, devices will only connect to one of them.

      If your internet speed has dropped after changing your password, check if the mode has been activated WPA3 in compatibility mode. Some older devices (such as printers or smart speakers) may not support this protocol, causing constant connection interruptions. In this case, revert to WPA2-PSK.

      6. How to create a strong Wi-Fi password

      A weak password is the main vulnerability of a home network. Hackers can crack it in a matter of hours, or even minutes, if it's too simple. Here are the rules for creating a strong password:

      • 🔐 Length: Minimum 12 characters (16+ is ideal). Short passwords can be cracked in seconds.
      • 📛 Complexity: a combination of uppercase letters, lowercase letters, numbers, and symbols. Example: Green$Tree77!Moon.
      • 🚫 What to avoid:
        • Names, dates of birth, nicknames of pets.
        • Sequences like 12345678 or qwerty.
        • Words from the dictionary (even in a foreign language).

      If you find it difficult to come up with a password, use a generator (for example, the one built into Google Chrome or 1Password). Here are examples of strong passwords:

      • Purple#Dolphin92$Rocket
      • Coffee@Morning!2026*Strong
      • 7Golden#Keys$Under%Bed

      Keep your password in a safe place, such as a password manager (KeePass, Bitwarden) or write it down on paper and hide it. Never send your Wi-Fi password via SMS or instant messaging—this is tantamount to giving away access to your network!

      Changing your password is just the first step to securing your network. To make your Wi-Fi truly secure, configure these settings:

      • 🛡️ Disable WPS: This function is vulnerable to brute-force attacks. Find it in the section Wireless → WPS and deactivate.
      • 👤 Enable guest networkIf you have frequent guests, create a separate network with limited access to local devices. Path: Guest Network.
      • 🔄 Update the firmware: Outdated software versions contain vulnerabilities. Check for updates in System Tools → Firmware Upgrade.
      • 📡 Hide the SSID (optional): This will make your network invisible to others, but you will have to enter the network name manually on each device. The option is located in Wireless → Wireless Settings → Enable SSID Broadcast (uncheck).

    If you have a router that supports TP-Link HomeCare (For example, Archer C5400X), activate the built-in antivirus and parental controls. This will protect your devices from malicious websites and limit your children's access to inappropriate content.

    ⚠️ Attention: Hiding your SSID doesn't make your network completely invisible to experienced hackers. It only makes it more difficult for random users to connect. For true security, use a strong password and WPA3.
    Can I change my Wi-Fi password using the Tether mobile app?

    Yes, if your router supports the app. TP-Link Tether (most modern models, including Archer And Deco). To do this:

    1. Connect to the router's network via Wi-Fi or cable.
    2. Open the app and select your device.
    3. Go to the section Settings → Wireless Network.
    4. Change your password and save the changes.

    The app will automatically reconnect your phone to the network with a new password.

    Why don't some devices connect after changing the password?

    This can happen for several reasons:

    • The device does not support the selected security type (for example, WPA3). Solution: go back to WPA2-PSK.
    • The password contains invalid characters (Cyrillic, spaces). Solution: Use only Latin characters and symbols. !@#$%^&*.
    • MAC address filtering is enabled on your router. Solution: Disable it. Wireless → Wireless MAC Filtering.

    If the problem persists, try "forgetting" the network on your device and reconnecting.

    How do I know who is connected to my Wi-Fi?

    To check the list of connected devices:

    1. Go to your router's control panel.
    2. Go to Advanced → Network → Clients or DHCP → DHCP Client List.
    3. You will see a list of all devices with their IP and MAC addresses.

    If you find an unfamiliar device, immediately change your Wi-Fi password and unplug it.

    Is it possible to change the Wi-Fi password without accessing the router?

    No, it's impossible to change the password without physical or remote access to the router. If you've forgotten your control panel password and can't reset the settings (for example, if the router is installed in a hard-to-reach place), contact your ISP—some carriers (e.g., Rostelecom or Beeline) can remotely reset the password for subscriber routers.

    What should I do if my router doesn't provide internet access after changing my password?

    First check:

    • Is the provider's cable connected to the port? WAN (usually highlighted in blue).
    • Are the indicators on? Internet And Wi-Fi on the front panel.
    • Have the settings been lost? PPPoE or DHCP (relevant if the provider requires authorization).

    If the Internet does not appear, try:

    1. Reboot the router (turn off the power for 30 seconds).
    2. Call your provider's support team - the problem may be on their end.
    3. Reset the router to factory settings and configure it again.
