Windows 7: Issue with my friend's Network Adapter

So my Friend recently upgraded his old Laptop (Dell Latitude C840) from Win XP to Windows 7 32bit. The only issue was that his network adapter was not being recognized. He couldn't connect to the Internet either wirelessly nor through Ethernet. I was perplexed and couldn't help him over the phone. I tried telling him to enable, disable the drivers in device manager but nothing seemed to work. I found the Dell driver download page for his laptop but am confused as to which one of the network drivers would fix his network adapter. Here is the link, could you give me some advice as to what to do next?

Hi there, Try these drivers for the wireless.

And this for the ethernet

See if they help!

And don't forget if they aren't windows Seven drivers to use compatibility mode to install. Fabe Compatibility Mode Also fromm\ the looks of the amount of different models avalible he may need to figure out which one he is actually using.http://support.dell.com/support/down...&catid=&impid=

Thanks for the help guys, I downloaded a driver off of Download.com that people said was compatible. He then used that driver temporarily to get onto the internet and update again through windows update. Now he's got both his wireless and his Ethernet working. Thanks again.
