Newbie question-M15x wireless question

Im new to  laptops and I just purchased an M15X, with what my mother calls all the *bells & whistles. I would like to be wireless throughout the home. My ISP is through the cable company, and I did have my desktop connected to an external modem. To be wireless I need a wifi card? and network adapter? (I have both on order) as well as a wireless router? (just purchased)  Its my understanding that I connect the router to the modem w/the adapter, and do a basic configuration and Im set?  Gosh, I really sound stupid...could someone please clarify...thanks in advance.
