I read your one paragraph too long needs breaking up story and may missed a few key items.
Let's start with this link:

I see only one HP driver offered which is the "HP Wireless Assistant" so you are left without drivers except for what MSFT offers.
Many are learning about installing windows for the first time. Many are used to ready to use machines with all the drivers pre-installed so your story sounds like you are only now discovering that Windows has for years never found the drivers for us.
You need to touch base with HP and see if they plan to issue more drivers.
