Preparation: What you need to know before changing your password

Before changing your password, make sure you have:

• 🔌 Access to the router - it must be connected to power and the network (Internet is not required).
• 💻 Tuning device — a computer, laptop, or smartphone connected to the router via cable or Wi-Fi.
• 📝 Factory data - If you have never changed the settings, the password and login for entering the control panel are indicated on the sticker on the bottom of the router (usually admin/admin or admin/password from the sticker).

If you have already changed the login/password for entering the router settings and have forgotten them, you will have to do it factory resetTo do this, press and hold the button Reset (usually it is recessed into the body) for 10-15 seconds until the indicators blink. After the reset, all settings, including the Wi-Fi name and password, will return to factory defaults and will need to be configured again.

Also check if there is a physical switch on the router. Wi-Fi On/OffIf it is disabled, the network will be unavailable and you will not be able to connect to change your password.

Step 1: Login to your TP-Link router control panel

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

1. Connect your device (computer, laptop, or smartphone) to the router via cable or Wi-Fi. If you've forgotten your current Wi-Fi password, use a cable.
2. Open any browser (Chrome, Firefox, Edge) and enter in the address bar 192.168.0.1 or 192.168.1.1If none of the addresses work, check the sticker on the router - it may indicate a different IP (for example, tplinkwifi.net).
3. Enter your username and password to log in. By default, this is admin in both fields, but if you changed them, use your data.

If the page does not open:

• 🔄 Check that the device is connected to this router (sometimes computers automatically connect to neighboring networks).
• 🔌 Reboot your router (turn off the power for 30 seconds and turn it back on).
• 🛠️ Disable VPN or proxy in your browser—they may block access to the local network.

Step 2: Find the Wi-Fi settings section

After successfully logging in, you'll see the main control panel page. The interface may vary depending on your router model and firmware version, but the general structure is similar:

In new models (Archer AX10, Deco X20) the interface is adaptive and looks modern, while in older (TL-WR740N, TL-WR841N) is simpler, with a blue or green background. Don't worry if your screen doesn't match the screenshots in the instructions: the steps remain the same.

Go to the section Wireless mode (or Wireless (in the English version). In some models it may be called:

• 📡 Wi-Fi settings (in new firmware)
• 🔄 Wireless Settings (in the old ones)
• 🌐 Network → Wireless Network (in some versions)

Where can I find the Wireless section in older models?

In routers TP-Link section released before 2018 Wireless often hidden in the menu Advanced (Advanced settings). If you can't find it, check the left sidebar or the top horizontal menu.

If you have a dual-band router (supports both 2.4 GHz and 5 GHz), you will see two sections: Wireless 2.4GHz And Wireless 5GHzThe password changes separately for each network.

Step 3: Change the Wi-Fi password

In the section Wireless mode find the fields:

• 🔤 Network name (SSID) — here you can change the name of your Wi-Fi network (optional).
• 🔐 Password or Wireless Password — Enter the new password here.
• 🛡️ Security type — choose WPA2-PSK (the most reliable option) or WPA3-PSK (if your devices support it).

Recommendations for choosing a password:

• ✅ Length must be at least 8 characters (preferably 12+).
• ✅ Use mixed case letters (AaBbCc), numbers (123) and symbols (!@#).
• ❌ Do not use personal information (date of birth, pet's name, phone number).
• ❌ Avoid simple combinations like 12345678 or qwerty.

Example of a strong password: Green$Tree77!Moon.

Password contains at least 12 characters|

The security type selected is WPA2-PSK or WPA3-PSK|

The network name (SSID) does not contain personal information|

All connected devices support the selected encryption type-->

After filling in the fields, click Save (or Save). The router will reboot, and all devices will be disconnected from the Wi-Fi network. They will need to be reconnected with a new password.

Step 4: Check the connection and troubleshoot problems

After changing your password:

1. On your devices (smartphone, laptop, TV), remove the old Wi-Fi network from the list of saved ones.
2. Find your network in the list of available ones and connect by entering the new password.
3. Check your internet access (open your browser and any website).

If the Internet does not work:

• 🔄 Reboot your router (turn off the power for 30 seconds).
• 📡 Make sure the internet indicator on your router is lit (usually blue or green).
• 🔌 Check the cable from your provider - it should be firmly inserted into the port WAN (usually blue in color).

If your device does not connect to Wi-Fi:

• 📱 On your Android smartphone: go to Settings → Wi-Fi, click on your network and select Forget. Then reconnect.
• 🍎 On iPhone: Settings → Wi-Fi, click on the icon i next to the network and select Delete this network.
• 💻 On Windows: Settings → Network & Internet → Wi-Fi → Manage known networks, select your network and click Forget.

• 🔄 Update your router firmwareGo to . System Tools → Firmware Update and check if the firmware version is up to date. Outdated firmware may contain vulnerabilities.
• 🚪 Disable WPSThis feature simplifies connecting devices, but it is easily hacked. Find the section WPS and deactivate.
• 👤 Change your login/password to access your control panel.By default this is admin/admin — such data is easy to find.
• 📡 Hide the SSID (network name). In the Wi-Fi settings, enable the option Hide SSIDThen your network won't be visible in the public list, but you can connect to it by entering its name manually.

It is also useful to include guest network For visitors. This will allow you to share internet without revealing the master password. The guest network can be limited in speed and access time.

How to enable guest network?

Go to Wireless Mode → Guest Network. Turn it on, set a separate name (for example, MyWiFi_Guest) and password. In the section Security settings select WPA2-PSK and limit speed if necessary.

If you have a router that supports TP-Link HomeCare (For example, Archer C9 or Deco M9 Plus), activate the built-in antivirus and parental controls. These free features block malicious websites and restrict access to content for children.
