Your wireless module should be displayed under "Network Adapters." If there's a yellow exclamation point next to the device, the driver isn't installed correctly or is conflicting with the system.

It often happens that a device is simply disabled by software. In this case, right-click the adapter and select "Enable." If the adapter is completely missing from the list, check the "View" tab and enable the display of hidden devices. This will help you see previously installed but currently unconnected modules.

⚠️ Important: If a device with error code 10 or 43 appears in Device Manager, this often indicates a hardware module failure or a deep driver conflict. Try completely uninstalling the device and updating the hardware configuration.

For proper operation on modern systems such as Windows 10 or 11, you may need to manually update the driver through the system database. Select "Update driver" → "Browse my computer" → "Choose from a list of available drivers." Sometimes the default driver Microsoft It works more stably than the proprietary one, although with limited functionality.

• 📂 Open Device Manager using the command devmgmt.msc.
• 👁️ Check the device's presence in the "Network adapters" section.
• 🚫 Make sure there is no prohibiting icon on your device.
• 🔄 Use the "Update hardware configuration" function when changes occur.

Using the Acer ePower Management utility
