After entering the IP address, you'll see a login window. Here you'll need to specify:

• Username: usually admin (default for TP-Link).
• Password: Also admin, unless you've changed it previously. If you have, use your current password.

• Network Name (SSID): You can leave it the same or change it (for example, add a suffix) _5G for 5 GHz network).
• Password (PSK): Here you enter a new password.
• Version and Encryption: select WPA2-PSK or WPA3-PSK (if supported).

Requirements for a strong password:

• 🔐 Length: minimum 8 characters (optimally 12+).
• 🔤 Combination: uppercase and lowercase letters, numbers, symbols (!@#$%).
• 🚫 Avoid: birth dates, names, dictionary words, repeating characters (1111, qwerty).

Important: If your router supports WPA3, select this standard—it provides better protection against brute-force attacks. However, some older devices (such as set-top boxes or smart bulbs) may not connect to this network. In this case, keep WPA2 or use mixed mode. WPA2/WPA3.

Typical problems and their solutions:

• 🔌 No connection after changing password: Restart your router and phone. If that doesn't help, reset the settings and repeat the procedure.
• 📶 Weak signal: Check if the Wi-Fi channel has changed in the settings (automatic selection is optimal).

• 🔄 Update your router firmware: in the section System Tools → Firmware Update Check that your firmware version is up to date. Outdated firmware may contain vulnerabilities.

• 🕒 Enable parental controls: Restrict internet access for children's devices during certain hours (section Parental control).
