I need a techie! Wireless internet software help.

[LP.]

So before I go and download 5000 things from sites claiming to be the software I need, I'll ask the techies of the community.

Long story short: My dad went on a deleting spree and accidentally deleted the software that our Belkin wireless router needs to actually get the wireless running. Well, I cant find the disk with the software and I cant figure out how to download the software off the net.

I've searched on google, and obviously 4 bajillion sites pop up claiming to have the software. I'm almost positive I shouldn't use any of these sites, and actually use Belkin's site. I've searched up the software I need, and I can download it, I just cant open it. My computer says I need to download some type of file opener and recommended a few. I tried downloading one, and it didn't open the file.

So, I'm absolutely stuck. I have no idea what to do from this point..

Information that will probably be useful:
Belkin Enhanced Wireless Router
Model: F6D4230-4 V3

Should I just go and buy a new router and fool my dad so he doesn't have too and get all mad with me, or can somebody thoroughly explain to me how to download the software.
I'm simply a kid who knows how to push the ON button, and use the internet. I'm not good with downloading and coding and all this fancy business

And he deleted it off of the control panel where you can add or remove programs, not just the desktop icon.
