Acer Launch Manager, which are responsible for hotkey functionality. Without them, the function keys may not work correctly.
Setting up a connection in Windows 10 and 11
After confirming that the hardware is active, you need to go to the operating system settings Interface Windows The process may differ depending on the version, but the logic remains the same. The system should automatically detect available access points and offer a list for selection.
Click the globe or computer icon in the lower right corner of the screen, next to the clock. If the icon has a line through it or displays an airplane, wireless mode is still disabled by software. In the menu that opens, find the "Wi-Fi" tile and ensure it's highlighted.
☑️ Check connection status
When you select a network, the system will ask for a security key. Enter the password carefully, observing the case of the letters, as WPA2/WPA3 Encryption is error-sensitive. If the password is saved correctly, Windows will attempt to obtain an IP address automatically via DHCP.
⚠️ Note: If you connect to a public network in a cafe or airport, the system may ask for detection confirmation. Answer "No" if you are in a public place to hide your laptop from other users.
Diagnostics via Device Manager
If the Wi-Fi icon is missing completely or appears with an exclamation mark, the problem lies deeper—in the drivers or the adapter itself. To diagnose this, you need to open device ManagerThis is the main tool for managing hardware components in Windows.
Right-click the Start button and select the appropriate menu item. In the window that opens, find the "Network adapters" section. Expand it and look for a device with the words "Network adapters" in its name. Wireless, Wi-Fi, 802.11 or brands Intel, Realtek, Qualcomm.

|---|---|---|
| Normal operation | No icons | There is a problem with the network settings. |
| Disabled | Down arrow | Right click -> Enable |
| Driver error | Yellow triangle | Update or reinstall the driver |
| Unknown device | Question mark | Install the driver from the Acer website |
If the adapter is marked with a yellow triangle, right-click it and select "Properties." The "General" tab will display an error code. Most often, this is code 10 or 43, which indicates a driver error. In this case, removing the device and restarting the laptop will help. Windows will then attempt to reinstall the driver.
What if the adapter is not on the list?
If there's no network adapters section at all in Device Manager, or the Wi-Fi adapter is missing, this may indicate a hardware failure.
