My name is Sujay and I work for the Social Media and Community Team at Dell.
You will find all avaiilable drivers on our support website. You can visit www.support.dell.com <http://www.support.dell.com/>
and look for specific wireless drivers by using either the system model or service tag.
If you have difficulties finding the driver let me know the exact system model and will look into it.
