Help, uninstalled wireless capability?

[henry]

So I was uninstalling programs. And I uninstalled some thing that said "broad 803.12 wireless utility" something like that. I want to know how I can get it back because I don't have internet right now. In the icons I press it and it says Internet unavailable. I trouble shooted and it said I had to connect to my internet cable? But idk how to. Help. If there's a way to get the download please tell me
