Sophia_16 :
I tried to search it but the link they are giving says "The page you're trying to view doesn't exist" like the link that you have provided. Btw, I'm not sure if we can request for a driver if we don't have the receipt anymore.
Actually you can...just bring the USB network adapter with you also a flash drive. go to the sale's rep show them the USB adapter and ask for a driver explain that the link the website is not working, every branch has a tech that can give you a driver.
seems the yousendit link they provided is not working anymore.
