Preparing to change your password: What you need to know in advance

Before you begin changing your password, there are a few key points to check. First, make sure your computer or smartphone is connected to the router. via cable Or via Wi-Fi. If you change your password from your phone wirelessly, the connection will be disconnected after saving the settings, and you'll have to enter the new password again.

Secondly, prepare factory login data in the control panel. Usually it's a combination admin/admin or admin/password (Indicated on the sticker on the bottom of the router). If you previously changed the login and password for accessing the settings but have forgotten them, you will need to reset the router to factory settings—we'll cover this in a separate section.

• 🔌 Connection: use a cable for stability (connector LAN on the router).
• 📝 Login details: login and password from the sticker or your current ones.
• 🔄 Backup: save current settings (optional, but useful).
• 📱 Devices: Remember which gadgets are connected to the network - they will have to be reconnected.

If you are not sure about the firmware version, look in the control panel: usually the version is indicated in the section Status or System Tools. For Archer C50 The current firmware for 2026 is TL-ARCHERC50(V5)_... (the exact version may differ).

Logging into the TP-Link Archer C50 router control panel

To change your Wi-Fi password, you first need to access your router's web interface. To do this, open any browser (Chrome, Firefox, Edge) and enter one of the following addresses in the address bar:

• 🌐 192.168.0.1 — standard IP for most TP-Link models.
• 🌐 192.168.1.1 — alternative address (less commonly used).
• 🌐 tplinkwifi.net — domain name for convenience.

If the page does not open, check:

1. Connecting to the router (indicator LAN or Wi-Fi should burn).
2. Disable your VPN or proxy as they may be blocking access.
3. Try a different browser or clear your cache.

After entering the address, you will see a login window. Enter your username and password (default admin And admin, if you haven't changed it). If the data doesn't match, check the sticker on the bottom of the router—it may contain unique credentials.

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

After successfully logging into the control panel, follow these instructions:

1. Go to the section Wireless (or Wireless mode in the Russian version of the interface).
2. Select a tab Wireless Security (Wireless security).
3. In the field Wireless Password (PSK password) Enter a new password. It must contain at least 8 characters, include letters and numbers. Special characters are allowed (!@#$% and others).
4. In the field Version (Version) select WPA2-PSK — is the most reliable encryption standard available today. If you have devices older than 2010 (such as older printers or smartphones), they may not support WPA2 - in this case, select Mixed mode. WPA/WPA2.
5. Click Save (Save) at the bottom of the page.

After saving, the router will reboot (this may take up to 1 minute). All devices will be disconnected from Wi-Fi, and you'll need to reconnect them with the new password.

Choosing an encryption type: WPA2 vs. WPA3 vs. mixed mode

When changing your password, you'll be asked to choose an encryption type. This affects not only network security but also compatibility with your devices. Let's consider the options:

If you choose WPA3, but you have an old device (for example, a printer HP LaserJet 1020 or smartphone Samsung Galaxy S3), it won't be able to connect to the network. In this case, go back to the settings and select WPA2-PSK or mixed mode.

What should I do if some devices won't connect after changing the password?

If your gadget doesn't see the network or displays an authentication error, try:

1. Restart the device.

2. Forget the network in the Wi-Fi settings and reconnect.

3. Check whether the device supports the selected encryption type (for example, WPA3 does not work on Android versions prior to version 10).

4. Temporarily return the old password and encryption type to check the functionality.

What to do if you forgot your control panel password

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

1. Factory reset. Press and hold the button Reset (usually located on the back panel) for 10 seconds. All settings will be reset, including the Wi-Fi password and control panel login information (they will become admin/admin).
2. Recovery via app TetherIf you previously configured your router using the official TP-Link app, try logging in through that app—sometimes it retains access even after changing the password.

After resetting, you'll need to reconfigure your router: enter your ISP information (if you have PPPoE or another connection type), change the network name, and change the password. If you're unsure of your internet connection settings, contact your ISP's support team—they'll provide you with the latest settings.

Common mistakes and how to avoid them

When changing a password, users often make mistakes that lead to connection issues. Here are the most common ones:

• 🔑 The password is too simple. Avoid combinations like 12345678 or qwertyui — they're easy to guess. Use a password generator or create phrases that replace letters with symbols (for example, M0skv@_Z1m@).
• 📵 Incompatible encryption. If you have chosen WPA3If you have an older device, it won't connect. Check compatibility beforehand.
• 🔄 Unsaved settings. After changing your password, always press Save and wait for the router to reboot. If you close the page prematurely, the changes will not be applied.
• 📡 Ignoring 5 GHz. Archer C50 Supports two frequencies: 2.4 GHz and 5 GHz. If you change the password for only one network, the other will remain with the same password (or without one).

Another common problem is dual networks with the same name. If you have both frequencies (2.4 and 5 GHz) enabled with the same SSID, devices may get confused when connected. We recommend using different names, for example: MyWiFi_2G And MyWiFi_5G.

Additional security settings

In addition to changing your password, we recommend paying attention to other security settings:

• 🔒 Disable WPS. This feature simplifies connecting devices, but it has vulnerabilities. Find the section WPS in the settings and deactivate it.
• 📡 Hiding network (SSID). In the section Wireless Settings You can disable network name broadcasting (Hide SSID). This will not make the network completely invisible, but it will reduce the number of connection attempts.
• 🛡️ MAC address filtering. In the section Wireless MAC Filtering You can specify which devices are allowed to connect to the network. This adds an extra layer of security, but requires manual control.
• 🔄 Firmware update. Please check this section regularly for updates. System Tools → Firmware UpgradeNew versions often patch vulnerabilities.

It is also useful to include guest network for visitors. This will allow you to distribute internet without access to the main network and its devices. The setting is located in the section Guest Network.

⚠️ Attention: If you enable MAC address filtering, new devices won't be able to connect to the network until you add their addresses to the allowed list. This can be inconvenient if you frequently have guests over with new gadgets.
