I have run the update to W10 and all went well until the end. The NetXtreme appeared to have lost its driver. As the system was now not on the internet there was nothing I could do. I rolled back to W7 as the only option and then I saw the driver automatically install itself in W7. How can I update to include the driver or is there a way I can download the driver first and then install in W10 when I get there? My system is Dell Precision 490 64 Bit Any assistance waould be greatly appreciated.
