I hold wireless experienced laptops. What are access cards? Are they already built surrounded by to my laptops?

Answer:

Access cards are add-ons that can be installed on elder machines that do not have deep-seated chips or are wireless ready. If you machines are capable, a short time ago configure them with the window network wizard or beside your router's wizard and you'll be set :)
access cards are the recevers that collect wireless connections. Some are built-in and some are not. Look at the manuel and it should tell you what you get and what you don;t have.
