Completed: 0 / 5

If the problem persists, proceed to the next section, where we'll cover manual network configuration.

4. Manually connect to Wi-Fi via Network Settings

Sometimes automatic connection fails due to specific router settings (for example, a hidden network or Enterprise authentication). In such cases, manually entering the parameters will help:

  1. Open Windows Settings (Win + I) → go to the “Network and Internet” → “Wi-Fi” section.
  2. Click "Manage known networks" → "Add new network".
  3. Fill in the fields:
    • Network Name (SSID): the exact name of your Wi-Fi network (case sensitive!).
    • Security type: usually WPA2-Personal or WPA3-Personal (check in your router settings).
    • Security key: Wi-Fi password.
  • Check the box "Connect automatically" and click "Save".

    • If you don't know your network's security type, check your router's web interface:

    1. Open your browser and type in the address bar 192.168.0.1 or 192.168.1.1 (the address may differ - look on the router sticker).
    2. Enter your login and password (usually admin/admin or admin/password).
    3. Find the section Wireless Settings (or "Wireless Network") - there will be information about the encryption type.
      4. What should I do if I can't access my router settings?

      If after entering 192.168.0.1 The page doesn't open, try:

      • 🔌 Connect to the router via cable (if Wi-Fi is not working).
      • 🔄 Reboot the router (disconnect power for 10 seconds).
      • 📱 Check your router's IP address via the command line: enter ipconfig and find the line "Default gateway".

    5. Diagnosing and troubleshooting connection errors

    Even if the adapter is working properly and the password is correct, Windows may display errors like "We couldn't connect to this network" or "Restricted Access." Let's look at the most common causes and solutions:

    ⚠️ Attention: If your router is configured to operate in the range 5 GHz, and the adapter only supports 2.4 GHz (or vice versa), the connection will be impossible. Check the adapter specifications and router settings.
    Error Possible cause Solution
    "Unable to connect to this network" Incorrect password or security type Check your password and encryption type (WPA2/WPA3) in the router settings.
