Go at control panel (if you use windows 7), Network and Internet , Network and sharing center.Check where it says "View your active networks" , under the network you are using it will say Home network or Work network. Click that and change it into Public network.Voila, network sharing center has disappeared!

This may not be a solution for you but at least it may explain the cause of the problem. I recently had the same problem - the scroll wheel suddenly began to go crazy, jumping all the way to the bottom or the top of a document, or randomly skipping around. The unit was still under warranty, and Microsoft sent me a new mouse. Since they did not require me to return the old mouse, I decided to take it apart to see if I could find the problem. I found poorly soldered electrical joints to the optical sensor & LED which convert the scroll wheel movement to electrical signals. After I resoldered these connections the mouse worked fine again.

Although the wireless switch on your Acer does turn on/off your wireless card, you will also need to make sure that your operating system (Windows) has the wireless card enabled.

Do the following:

1. Go to Control Panel (Start -> Control Panel)
2. Double-click Network Connections
3. Right-click on Wireless Network Connection / WLAN (you can tell it is disabled if the icon is greyed)
   
   
4. Click on "Enable" (if you see Disable, your network is already enabled)
   

You should check the bottom-right-hand area of your screen (in the menu bar) for your wireless icon. If this is not appearing, you'll have to go into Network Connections again and do the following:

1. Right-click on Wireless Network Connection (your wireless network adapter)
2. Select Properties
3. Click the checkbox that says "Show icon in notification area when connected"
   
4. Now click on the Wireless Networks tab (at the top of this dialogue box)
5. Scan for a network and connect to it.
   

Try this to check the wireless.

Click on start> Control panel> network and internet connection> from left pane click on view network connection after that right click on the wireless adopter icon and select enable.
this will resolve the issue if it is not helpful
