• 🔌 Router TP-Link plugged into the network and works stably (the power indicator is green or blue).
• 💻 A device (PC, laptop, smartphone) connected to the router via cable (recommended) or via Wi-Fi.
• 📝 Factory login data: login and password (usually admin/admin, but may differ).
• 🔒 New Wi-Fi password (think of one in advance, see the tips in the next section).

If you don’t remember the factory login/password, don’t panic: they can be found on the sticker on the bottom panel of the router (field Username/Password or Login). If there is no sticker or the data has been erased, see the table in section 3.

• 🔐 Length must be at least 12 characters (optimally 15-20). Short passwords can be guessed in a few minutes.

• 🔢 Add numbers and special characters: !, @, #, $But not at the beginning or the end - that's predictable.
• 🚫 Eliminate personal information: dates of birth, pet names, phone numbers.
• 🔄 Change your password every 3-6 months, especially if guests connected to the network.

Don't want to remember a complex password? Use password manager (For example, KeePass or Bitwarden) or Built-in password generator in new TP-Link firmware (available in the section Wireless → Wireless Security).

3. Login to the TP-Link router control panel

To change your Wi-Fi password, you first need to access your router settings. To do this:

1. Open your browser (Chrome, Firefox, Edge) on the device connected to the router.

4. Step-by-step instructions: how to change your Wi-Fi password via the web interface

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

1. Go to the section Wireless (or Wireless mode in Russian-language firmware).
2. Select a tab Wireless Security (Wireless security).

After saving, the router will reboot (this will take 1-2 minutes). All devices will be disconnected from Wi-Fi and will need to be reconnected with the new password.

If you don't see the section Wireless:

• 🔍 On newer firmware versions, the path may be different: Advanced → Network → Wireless Settings.
• 🌐 On some models (Archer AX55) first you need to select the range: 2.4GHz or 5GHz.
• 🔄 If the interface is in English and you want Russian, there's a flag in the upper right corner to change the language.

For dual-band routers (Archer C6, AX20) you will have to change the password separately for 2.4 GHz And 5 GHzThe network names (SSID) can be the same or different - this does not affect security.

What should I do if Wi-Fi doesn't work after changing my password?

If after saving the settings Wi-Fi disappears or devices do not connect:

1. Check that the router has completed rebooting (the indicators are lit steadily).

2. Make sure you entered your password correctly (case-sensitive!).

3. Try connecting via cable and check the settings again.

4. If nothing helps, reset the router using the button Reset and configure it again.

6. Common mistakes and how to avoid them

Even though the process seems simple, users often encounter problems. Here are the most common errors and their solutions:

• 🔑 Incorrect password when entering settings: If you changed your login/password for the control panel and forgot it, the only thing left to do is (button Reset).
• 📡 Wi-Fi won't turn on after changing the password: check that the radio module is not disabled in the settings (Wireless Radio should be Enabled).
• 🔌 Devices do not connect to the new network: Make sure you enter your password in the correct case (eg. P And p - different symbols!).
• 🌐 Page 192.168.0.1 won't open: try another browser or check the IP address via command ipconfig (V Windows) or ifconfig (V macOS/Linux).
• 🔄 The router constantly rebootsThis could indicate a malfunction or IP address conflict. Try disconnecting all devices from the network and resetting the settings.

If after changing the password the Internet is lost, but Wi-Fi works (devices connect, but there is no network access), check:

• 🔌 Connecting the cable from the provider to the port WAN (usually blue in color).
• 📡 Settings Internet or WAN in the control panel (the connection data to the provider may have become corrupted).
• 🔄 Reboot the router and modem (if separate).

If nothing helps, use diagnostics in the application Tether (chapter Tools → Diagnostics) or contact support TP-Link.

7. Additional security settings

Changing your password is just the first step to securing your network. We also recommend setting up:

• 🔒 Guest network: Create a separate network for guests with limited access to local devices. Path: Wireless → Guest Network.
• 👶 Parental control: Restrict access to certain sites by time or device (Advanced → Parental Controls).
• 🔄 Firmware update: Check the section regularly for updates System Tools → Firmware Upgrade.
• 📡 MAC address filtering: Allow only trusted devices to connect (Wireless → Wireless MAC Filtering).
• 🔌 Disabling WPS: This feature is vulnerable to hacking. Turn it off. Wireless → WPS.

For maximum safety:

• 🔐 Use WPA3-PSK instead of WPA2-PSK (if the router supports it).
• 🔄 Change the password for the router control panel (do not leave it admin/admin!).
• 📡 Disable remote control (Security → Remote Management), if you don't use it.

If you have a router that supports TP-Link HomeShield (For example, Archer AX6000), enable this feature for enhanced protection against viruses and malicious websites. It works at the network level and protects all connected devices.
