dell n4110 driver problem  

I had recently posted a thread in the wrong section about a dell n4110 laptop. I wiped and installed an OEM for windows 7 64 bit SP 1. I have no drivers that I can use listed under Other Devices, such as Ethernet Controller, Network controller, PCI Simple Communications Controller, SM Controller and USB Controller. I cannot used the dell laptop to download these . I need to download them on another PC,transfer to a flash drive and install them on the Dell using some kind of program. Any information or suggestions on this problem would be greatly appreciated. Thank you.
