Internet Connection help

[braz]

OK, so I re formatted my friend's DEll Dimension E310. I cannot connect to the internet. I looked at the device manager and there is a quesion mark next to a lot of drivers. The only diver disc he has is for his monitor and printer. I did find this website for him, but am not sure what to download. He does not have wireless internet, he is hard wired. Here is a link to the drivers, if someone could let me know which to download so I can put it on a flash drive and bring it over, that would be great. Thanks!
