i think you may have the model number wrong.... i cannot find that model anywhere? are you turning the laptop upside down and looking on the bottom..? If you are able to find a different model that way then post back and let me know. If not then lets just see if the wireless device is shown in.....
Click on START, and then RUN...... and type in: devmgmt.msc and then click the OK button.
When the device manager opens scroll down to network adapters and post back every device listed in there
also see if any of the devices have a RED X or YELLOW ! on them....
When done close out the device manager and then.....
Click on START, and then RUN...... and type in: ncpa.cpl and then click the OK button.
when the Network connections window opens check the device listed in this window against the devices listed in the device manager and let me know if they are the same, or not.
If your wireless device is listed in the network connections window then right click on it and select PROPERTIES
When the properties window opens check either the first tab or the second tab (I don't have my wireless installed right now so i cant walk along with you) for a small white box that says next to it "use windows to configure this device... blah blah blah".... make sure there is a check in that box. Was there?
If there was no check in that box, then see if you can connect now?
