Fresh Windows Install. 19 different Network Drivers. Which one do i download?

I have almost downloaded them all at this point for lack of a better solution. Why are you using such a high variety of manufactures for *** sakes. 

How can I find out which Wireless card is in this machine and which ethernet card it has? Same problem will surely exist with display adapters and so forth. How can I determine when the Device Manager is just listing the generic drivers installed from Microsoft?...
