Make sure the airplane icon isn't blue, as this mode disables all radios. Wi-Fi adapter completely disconnected from power supply.
Activating Wi-Fi through Windows Settings
operating system Windows Provides a user-friendly interface for managing network connections, which is often overlooked by users. To access the settings, right-click the network icon in the system tray and select "Network and Internet Settings." In the window that opens, select the "Wi-Fi" section on the left, where the main module status switch is located.
Move the slider to the "On" position, and the system will begin searching for available networks. If the switch is missing or inactive (grayed out), this may indicate a more serious issue with drivers or services. In such cases, the operating system will not detect network adapter as a working device.
In the deeper settings, accessible through the "Change adapter settings" menu, you can manage specific connections. All network interfaces installed on the system are displayed here. Find the "Wireless Network" icon, right-click it, and select "Enable" if it was previously disabled.
- 📡 Click on the globe or antenna icon in the tray for quick access.
- 🔘 Make sure Airplane Mode is turned off in Control Center.
- 🔄 Restart your laptop if the switch in the settings does not respond.
- 💻 Check if your antivirus software is blocking network connections.
Setting up via Device Manager
If standard methods don't help, you need to proceed to hardware-level diagnostics. To do this, open Device Manager by entering the appropriate query in the Start menu or by running the command devmgmt.mscIn the list of devices, find the "Network Adapters" section and expand it. All network cards, including the wireless one, should be displayed here.
If you see a device with a name containing the words Wireless, Wi-Fi, 802.11 or brands Intel, Realtek, Qualcomm, but its icon has a downward-facing arrow, meaning the device is disabled. Right-click it and select "Enable." If the icon has a yellow exclamation point, this indicates an error. device drivers.
If your wireless adapter isn't listed at all, try clicking "Action" -> "Scan for hardware changes." This will force the system to rescan the connected components. Sometimes the adapter may appear in the "Other devices" section as an unknown device, which also requires driver installation.
⚠️ Warning: Do not attempt to blindly remove unknown devices. First, check their properties and hardware ID to ensure they are your Wi-Fi module and not a system component.
What to do if the device is hidden?
In the Device Manager menu, select "View" -> "Show hidden devices." If the adapter appears translucent, try uninstalling it and restarting the computer to reinitialize it.
Checking and updating drivers
The correct operation of the wireless module directly depends on the installed software. Drivers are special programs that allow the operating system to communicate with the hardware. On laptops Acer Conflicts often occur after Windows updates when the system installs a generic driver instead of the original one.
To install or update manually, right-click the adapter in Device Manager and select "Update driver." Select automatic search, but if it doesn't find anything new, it's best to download the latest version from the manufacturer's official website. Enter your laptop model (e.g., Acer Nitro 5) in the search field on the support site Acer and download the driver for your version Windows.
Driver installation requires administrator privileges and may take several minutes. Once the process is complete, be sure to reboot your system. If the issue was a software glitch, reboot. Wi-Fi module should work correctly.

Diagnostics via command line
For advanced users and in cases where the graphical interface doesn't work, the command line is a great tool. It allows you to reset network settings and check the status of the WLAN service. Open the command line as administrator by entering cmd in the search and selecting the appropriate item.
The first thing you should do is check whether the WLAN autoconfiguration service is enabled. Enter the command net start wlansvcIf the service is already running, the system will notify you. If it was stopped, this command will start it, which can immediately activate network discovery.
netsh winsock resetnetsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
Running the above command sequence resets the TCP/IP protocol stack and flushes the DNS cache. This is especially useful if your laptop sees networks but can't connect, or if the adapter is unstable. After running all the commands, you must restart the computer.
⚠️ Note: Command prompt interfaces may vary slightly depending on your Windows version and localization. If the command fails, check that you entered it correctly and that you have administrator privileges.
