All-in-one PCs Acer Wireless network adapters are a stylish and compact solution for home and office use, combining a system unit and monitor into a single housing. However, the lack of traditional physical ports on the front panel sometimes creates the illusion that the wireless module is missing or not working. Users often encounter a situation where the network icon in the system tray displays a "red ball" or a crossed-out computer, even though the internet was working perfectly just yesterday.
Reasons why wireless adapter If your device stops working, there could be a variety of reasons: from accidentally shutting down via hotkeys to driver failure after an operating system update. Unlike laptops, where the Wi-Fi switch is often located on the edge of the case, in all-in-one PCs, electronic controls are often software-based or hidden in the BIOS settings menu. Understanding your device's architecture is the first step to successfully resolving the problem.
In this article, we will examine in detail all possible activation methods. Wi-Fi module on Acer devices.

Installing and updating Wi-Fi drivers
Lack of up-to-date software is the most common reason for unstable network operation on all-in-one PCs. AcerStandard Windows Update drivers are often stripped down and do not support all power-saving features or the latest security standards. WPA3For proper operation, it is necessary to use the specified versions from the manufacturer's official website.
Since the internet may not be available on the all-in-one PC, you'll need to download drivers from another device (laptop, smartphone) and transfer them via USB. Go to the official support website. Acer, enter your device's serial number (SNID) found on the sticker on the back of the case. Select your operating system and find the "Driver" -> "Wireless LAN" section.
| Chip manufacturer | Typical name in the system | |
|---|---|---|
| Intel | Intel Wireless AC 9560 | Download from the Intel or Acer website |
| Realtek | Realtek RTL8822BE | Only from the Acer website |
| Qualcomm Atheros | QCA6174A | Check version compatibility |
| Broadcom | Broadcom 802.11ac | Use Windows 10/11 driver |
After downloading the installation file, run it as administrator. Follow the installation wizard's instructions. It's important to note that after installing the driver, a reboot may be required for the changes to take effect. If automatic installation doesn't help, try manually updating the driver through Device Manager, specifying the path to the folder containing the unzipped files.
Setting up power options
The Windows operating system strives to save energy, and sometimes this leads to it turning off network adapter to reduce power consumption. On all-in-one computers, this can manifest as intermittent connection drops or the adapter failing to turn on completely after waking from sleep mode. Disabling this feature often solves the Wi-Fi dropout problem.
To prevent the system from powering down the adapter, return to Device Manager. Find your wireless adapter, right-click it, and select "Properties." Go to the "Power Management" tab. Uncheck "Allow the computer to turn off this device to save power." This will force the module to run in permanent mode.
- ⚡ Disabling power saving may slightly increase power consumption, but will ensure a stable connection.
- 🔄 After changing the settings, be sure to restart the all-in-one PC for the changes to take effect.
- 📉 If the problem persists, check the power plan in Control Panel and select "High Performance" mode.
It's also worth checking the settings in the router itself. Sometimes all-in-one routers Acer may conflict with the router's energy-saving features. Try changing the Wi-Fi channel to a more accessible one or switching the operating standard. 802.11 b/g/n on 802.11 ac/ax, if your adapter supports new standards.
Windows Services and Network Reset
In the Windows operating system, wireless connections are managed by special background processes called services. If the "WLAN AutoConfig" service is stopped or not running correctly, you won't be able to enable Wi-Fi through the interface, even if the drivers are installed correctly. This is a common issue after cleaning the system with third-party optimizers.
To check, press the key combination Win + R, enter services.msc and press Enter. Find the service in the list. WLAN AutoConfig (or "WLAN AutoConfig Service"). Double-click it. Make sure the startup type is set to "Automatic" and the service status is "Running." If it is stopped, click the "Start" button.
