What you should do is go up to the websites (HP.com, Toshiba.com) and look up the laptop you're looking into getting. Be 100% before buying it. I mean you don't want to go on my word (or anyone else for that matter), open up the box and go "Where is the Wi-Fi switch on this thing?....... it doesn't have one?....................", that wouldn't be too good. XD
But yea, I'm pretty sure ALL laptops these days have Wi-Fi.
