try connecting to another location like the public library. it could be that your router security setting may be set too high.

Installation speed and simplicity Installing a wireless LAN system can be fast and easy and eliminates the need to pull cables through walls and ceilings. Components of a wireless LAN To set up your Wireless network at home you need to have the following:

Access point (router)
Access points (routers) are two-way transceivers that broadcast data into the surrounding environment. Access points act as a mediator between wired and wireless network. Most routers have a built-in DSL modem that will allow you access to a high speed DSL internet connection. The ISP (Internet Service Provider) you have chosen normally supplies a modem/router with the subscription to their services. Read carefully the documentation supplied
with your Access point/router for detailed setup instructions

Follow the on-screen installation instructions.
Access the Acer's Start menu and open the Control Panel.
Click "Network and Sharing Center," and then choose the "Set up a new connection or network" link.
Choose "Set up a new network" and then "Next."
Enter a name for your local area network, such as "Home" or "My Network," into the "Network Name" text field.
Type a password for your network in the "Security Key" text box and click "Next."
Click "Finish." Right-click the "Acer eNet Management" icon in the Windows task bar.

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.
