Issues with WIFI on new PC

I recently bought a Laptop with an unknown OS (I forget the name, but it wasn't windows) and had to format it, and afterwards got Windows 7 working on it. For some reason, I'm not getting any wifi, help please
 
What you could do is go online to the laptops manufacturer & get the manual for it to see if there is a key or combination of keys to use to go online. http://www.manualsonline.com/

Ehhhh, thanks, but nothing I found really helped, I'm able to connect to the internet, but I'm not able to connect without a network cable, which is a hassle because I am really loud and my family doesn't like me playing, especially when I like to play most, what I need is help setting up WIFI
 
Playing LOUD? Get headphones so they can't hear it. Otherwise, try getting a USB wifi
When I say playing loud, I mean I have a microphone, and I basically yell into it, because I play using a program called Steam, and yeah, also I'm only 14 so I don't have money, I just need help with getting WIFI working on my PC without spending money, any way to do that?
