The Acer Aspire One is an inexpensive laptop computer that runs the Windows operating system. The computer does come with a built in Wi-Fi receiver, giving you the ability to connect to a wireless Internet network, when available. However, if you are having trouble connecting to a wireless network, you must troubleshoot the network connection to determine exactly what is causing the problem with the Internet.
Check the wireless router and high-speed modem. If the two are not powered on, or if the Ethernet cable connected the two is not completely inserted into both connection ports, you are unable to access the Internet on the Acer Aspire One laptop computer.
Activate the wireless Internet connection on the laptop computer. Right-click the wireless icon on the desktop, then choose "Enable" from the pop-up menu. Without activating the wireless receiver on the Acer Aspire One, the laptop is unable to detect any wireless network.
Select the appropriate network you wish to connect to. Your computer may be attempting to connect to a different Internet connection, preventing you from access the network you desire. Right-click the wireless icon, select "Search for available wireless networks," then choose the network you want to access.
Restart the computer. The system may have booted and failed to detect the wireless receiver. Restarting the computer corrects this issue.
