Still need to know what OS version you're running; Windows 7 32-bit or 64-bit, but from what I found
here, we're going to need more information.
Click the start button and go to Control Panel.
Click on Hardware and Sound
Under Devices and Printers. click Device Manager
In the Device Manager Window, click the triangle next to Network Adapters to expand that selection.
Report back with what it says or you can go to the
Dell Web Site and download the matching driver.
For the Operating System drop down, select which version of Windows 7 you're running. For the Category, select "Network". Find the driver that matches what Device Manager reports, download, move it to your Dell and install it. That should get you up and running.
