The Acer Aspire One is a netbook manufactured by Acer. Netbooks are designed to be extremely portable and convenient for their users. One of the accessibility features standard on the Aspire One is a wireless network card which allows the netbook to connect to any Wi-Fi network that is in range, provided that the user possesses the credentials to access the network. If the Aspire One can't access a wireless network, there are several troubleshooting steps that might resolve the issue.
Locate the wireless router for your network and verify that it is plugged in and powered on. When turned on, you will see a series of lights illuminated on the front or top of the device.
Power on your laptop computer, if it is not already turned on.
Press the "Fn" and "F2" keys simultaneously to turn on the wireless connectivity option for your Acer Aspire One. You may need to press these keys several times until the light above the wireless symbol glows orange.
Click the "Wireless Network Icon" in the system tray at the lower right corner of the screen. This icon looks like a computer with semicircles next to it.
Select the SSID of the wireless network that you wish to connect to, then click the "Connect" button.
Type the security key for the wireless network when prompted, then click "Connect."
If your Acer Aspire One displays your target network in the "Available Wireless Networks" window but you are unable to access the network using the security key, then an additional security precaution, known as MAC filtering, may be enabled on this network. Contact the network administrator to have your Aspire One added to the list of devices allowed on the network.
