Bill,   Try the drivers from this thread... Installing My Wi-Fi Technology   They'll be from Intel's website and it will install Intel® My WiFi Technology because you'll have the adapter.     Rick  
I have the Wireless 5300 PCI Express Internal Half-Height Mini-Card ordered and now need to find the drivers.  My system is a 1735 Studio laptop running 64bit Windows 7.  The Dell sales rep said the card came only with the card and a flat head screw.(no instructions, figures) Thanks in advance Bill
