WPA3-PSK	⭐⭐⭐⭐⭐	Devices after 2018	The best choice if all gadgets are new
WPA2-PSK	⭐⭐⭐⭐	All devices	Optimal for most users
WPA/WPA2-PSK	⭐⭐⭐	All devices	Compromise for compatibility
WEP	⭐	Obsolete devices	Do not use!

5. Change your password via the Tether mobile app

If you prefer to configure your router from your smartphone, use the official app. TP-Link Tether (available for Android And iOS). This is especially convenient for models Deco or if you do not have access to a computer.

6. Enter a new password, save the changes and wait for the router to reboot.

Advantages of the application:

• 📱 Convenient interface on your phone.
• 🔄 Quickly reboot the router after changes.

Flaws:

• 🚫 Fewer settings compared to the web interface.
• 🔄 Sometimes the app doesn't detect the router. In this case, check your connection to its network.

⚠️ Attention: In the attachment Tether there is no way to change the security type (for example, with WPA2 on WPA3). You'll still have to use the web interface for this.

6. What to do if you forgot your admin panel password

If you don't remember your login or password for logging into your router settings, there are two ways to solve the problem:

Method 1: Recover data from a sticker

On the bottom side of the router TP-Link There's always a sticker with factory data. Look for the following fields:

• 🏷️ Username - usually admin.
• 🏷️ Password — factory password (for example, admin or a unique combination).
• 🏷️ SSID — the name of the default Wi-Fi network.
• 🏷️ Wireless Password — factory Wi-Fi password (if not changed).

Method 2: Reset the router to factory settings

If the data from the sticker is not suitable or there is no sticker, do hard reset:

• 🔄 Wi-Fi name and password.
• 🌐 Internet connection settings (you will have to configure them again).
• 📡 Guest network, parental controls, and other features.

7. Common mistakes and how to avoid them

Users often encounter problems when changing their passwords. Here are the most common ones and how to solve them:

Problem	Cause	Solution
Unable to log into the control panel	Incorrect IP address or login/password	Check IP via ipconfig, reset the router or use the data from the sticker
After changing the password, Wi-Fi does not work.	Incorrect security type	Select WPA2-PSK and re-save the settings
Devices do not connect to the new network	The password is too complex or incompatible WPA3	Simplify your password or go back to WPA2
The router constantly reboots	Firmware failure or settings conflict	Reset and reconfigure your router

A few more tips:

• 🔄 If you lose internet access after changing your password, check your settings WAN (maybe the connection to the provider was lost).
• 📶 If your Wi-Fi speed has dropped, try changing the channel in the settings Wireless (select Auto or manual channel with minimal interference).
• 🔌 If the router doesn't respond to pressing, check the power supply - it may be faulty.

8. Additional security measures for Wi-Fi networks

Changing your password is only part of securing your network. To make it truly secure, follow these recommendations:

• 🔄 Update your router firmware. Go to the section System Tools → Firmware Upgrade and check if the version is up to date.
• 🛡️ Disable WPSThis feature is vulnerable to hacking. Find it in Wireless → WPS and deactivate.
• 👤 Change the administrator login and passwordBy default this is admin/admin - too predictable.
• 📡 Create a guest network for visitors. This way, they won't know the main password.
• 🔍 Enable MAC address filtering (optional). This will add another layer of security, but may make connecting new devices more difficult.

It's also a good idea to change your Wi-Fi password regularly (every 3-6 months). This will reduce the risk of unauthorized access, especially if you frequently share the password with guests.

To check the security of your network, you can use special applications, for example WiFi Analyzer (For Android) or NetSpot (For macOS/Windows). They will show how strong your password is and whether there are any suspicious connections.

How to check who is connected to your Wi-Fi?

Go to your router's control panel and find the section DHCP → DHCP Clients List or Wireless → Wireless StatisticsThere will be a list of all connected devices with their IP and MAC addresses. If you see any unfamiliar devices, change the password and enable MAC filtering.
