⚠️ Note: On some models Acer The Wi-Fi function is completely disabled when the battery is removed if the laptop was running on AC power. Try disconnecting the charger and pressing the power button again.
Diagnostics via Windows Device Manager
If the physical buttons don't help, you need to check whether the operating system sees the network adapter itself. To do this, open device ManagerBy right-clicking the Start button and selecting the appropriate option from the menu, find the "Network adapters" section in the list of devices and expand it.
If you see the name of your adapter (often it is Intel Dual Band, Realtek or Qualcomm Atheros) with a yellow exclamation point, it means the driver is not working properly. If the adapter is displayed as "Unknown Device" or is missing entirely, the problem may be a hardware failure or a faulty module. Try right-clicking and selecting "Enable" if the device is disabled.
A common mistake is setting up a power plan. The system may shut down the device to save power, after which it is unable to wake it up. Double-click the adapter, go to the "Power Management" tab, and uncheck "Allow the computer to turn off this device." This often resolves the issue of random shutdowns.
devmgmt.mscEnter this command in the Run window (Win + R) to quickly open Device Manager without unnecessary menus. This is a universal way to access hardware management in the environment. Windows 10 And Windows 11.
Updating and reinstalling drivers
Proper operation of the wireless module directly depends on the version of the installed software. Drivers that Windows installs automatically through the update center are often basic and may not support all the features of your device. router or a specific module AcerIt is recommended to download the latest version from the manufacturer's official website.
Visit the support page Acer, enter your laptop model (for example, Acer Nitro 5 AN515) and go to the drivers section. Select your operating system version and download the file marked as Wireless LAN Driver or WLANBefore installing the new version, it's best to completely uninstall the old one via Control Panel → Programs and Features.
After removing the old software, restart your computer and install the downloaded driver. If there's no official driver for your version of Windows (for example, you've upgraded to a newer OS), you can try installing the driver from the previous version in compatibility mode. To do this, right-click the installation file, select "Properties" → "Compatibility," and select the desired Windows version.
☑️ Driver Update Checklist
⚠️ Caution: Do not use third-party driver updaters. They often install generic versions of software that can cause unstable Wi-Fi performance on laptops. Acer.
Configuring network services and settings
In the operating system Windows A special service is responsible for wireless connections. If it's stopped or disabled, the Wi-Fi icon may disappear completely or be inactive. Checking the status of these services is an important diagnostic step that's often overlooked.
Click Win + R and enter the command services.mscIn the list that opens, find the "WLAN AutoConfig" service. Make sure the startup type is set to "Automatic" and the service status is "Running." If not, change the settings and click "Start."
It's also worth checking your TCP/IP settings. Resetting your network settings can resolve addressing conflicts that are blocking the connection. Open a command prompt as administrator and run the commands to reset the TCP/IP stack and DNS cache. This will reset your network settings to factory defaults.
netsh winsock resetnetsh int ip reset
ipconfig /flushdns
After running these commands, be sure to restart your laptop. The changes will only take effect after a system restart. If the issue was a software conflict with network protocols, this method should restore functionality.
What should I do if the WLAN AutoConfig service does not start?
If an error occurs when starting the service, check for dependencies on other services. In the WLAN AutoConfig service properties, on the "Dependencies" tab, make sure the NDIS usermode I/O protocol and RPC services are running. Without these services, Wi-Fi will not function.
