Sometimes the system prompts you to enable Airplane Mode, which forcibly blocks all radios—make sure it's disabled.
For more advanced settings, go to the settings section. To do this, click Start → Settings → Network & InternetHere you can view the adapter's status and manage additional features, such as MAC address promiscibility or proxy settings. If the Wi-Fi slider in this menu is missing or grayed out, this is a sure sign of driver or service issues.
- 🔹 Click on the globe or monitor icon in the tray to open the quick menu.
- 🔹 Make sure Airplane Mode is deactivated, as it blocks the signal.
- 🔹 Check if the Wi-Fi icon is blue, which means it is actively searching.
- 🔹 If the icon is crossed out, try clicking on it to activate the module.
Configuring a network adapter in Control Panel
A more traditional way to manage your network is through the classic Windows Control Panel. This method allows you to see all available network interfaces, including those hidden or disabled programmatically. Press the key combination Win + R, enter the command ncpa.cpl and press Enter.
In the "Network Connections" window that opens, find the icon Wireless network or Wi-FiIf it's grayed out and labeled "Disabled," right-click it and select "Enable." The system will begin initializing the driver and attempting to connect to known networks.

|---|---|---|---|
| Disabled | Grey | Right-click → Enable | Activating the adapter |
| Identification | Yellow | Diagnostics | Obtaining an IP |
| Connected | Blue/Green | No action | There is Internet |
| No connections available | Red Cross | Checking drivers | Finding the cause |
In the same window, you can check the adapter properties. Select the Wi-Fi connection and click Properties and make sure that the protocol Internet Protocol version 4 (TCP/IPv4) is active and configured to obtain addresses automatically.
