Certain models of Acer desktop computers are designed with wireless capabilities.
These capabilities can be added to an Acer desktop system that does not connect wirelessly with either an internal or external wireless card, depending on the computer's configuration.
When the wireless connection is not working properly, you can troubleshoot the issue yourself.
The troubleshooting process eliminates the problems that may be preventing the Acer desktop computer from connecting wirelessly.

Check to see if any other computers at the same location are able to connect wirelessly.
The issue may reside with the wireless router or access point.
Power cycling the router or access point may resolve this issue.
Verify that the wireless adapter is enabled.
Click the "Start" button, then "Control Panel."
Click "Network and Sharing Center," then "Change Adapter Settings."
If the wireless adapter is disabled, right-click on it and select "Enable."
Connect to the proper wireless network.
The Acer may be attempting to the connect to the wrong wireless network, or it may have lost its connection to the correct network.
Click the wireless network icon in the task bar.
Click the proper wireless network, then click "Connect."
Enter the network password (or WEP key) if prompted.

Check that wireless service is running
XP: Click Start, click Run, type services.msc, then press Enter.
Scroll down to "Wireless Zero Configuration" and right click on it and select Properties. Set it to Automatic and not Disabled, and press the Start button, then click OK.
That should start the service.
7 (vista): Click Start, type services.msc, then press Enter.
Scroll down to "WLAN AutoConfig" and right click on it and select Properties. Set it to Automatic and not Disabled, and press the Start button, then click OK.
That should start the service.



To enable wireless adapter we need to go to device manager and enable it.
XP:
1. Right click on My Computer and click on properties.
2. Click on Hardware tab on system properties window.
3. Click on Device Manager
To go to device manager we need to click on the device manager button.
Now we can see all the hardware devices connected to the computer. To see the status of our wireless adapter click on network adapters.
4. Enable the Wireless adapter
To enable wireless adapter, right click on it and click on enable.
7 (vista):

1. Open the Start Menu by clicking the Start button. Click on Control Panel.
   
2. In the Control Panel, click on Network and Internet.
   
3. In the Network and Internet panel, click Network and Sharing Center.
   
4. In the Network and Sharing Center, click "Manage network connections" in the Tasks list on the left side of the window.
   
5. The Network Connections manager will open. Right-click the icon labeled Wireless Network Connection and click Enable on the menu displayed.

The last step checks if you have the wireless switch on or off. Locate the wireless button (in the middle, above the keyboard). Try to toggle it, see if is says anything.

If you get that message, believe it.
You will have to enable it either through the software switch or a little switch that some computer manufacturers place on the computer case.
The first thing you can do is open your network connections and see if you can see the wireless connections. If it says disabled, you might be able to right-click on it and enable it.
You can also look in the control panel to see if the HP wireless assistant can be accessed through there (or possibly through the programs list).

1)Go to Start Menu
2)Choose Control Panel
3)Choose Network Adapters or Network and sharing center
4)Right click the wireless adapter (it should say disabled in grey letters beneath the adapter) Vista users will have to choose Manage network connections from the left hand menu before they will be able to see the network adapters.
5)Choose enable
That should do it.

Good Luck
