Hi Neurotics,
In order to install correct driver for your wireless card, you would need to check the wireless card installed on your computer. You can check the wireless card installed on your computer from the 'Device Manager'. Another way is to check the wireless card shipped with your computer from system configuration webpage, under 'Original system configuration' Tab. You can click on the link: http://dell.to/137Ex95
If you are not able to find the wireless card of your computer. You may send me the system information via private message (click my username and then click Start Conversation).
Awaiting your response.
