It depends on the type of wifi adapter. The 3 most common ones are b, g, and n. First check the type of adapter your laptop has. Mine, for example, is wireless n. If you have a wireless g adapter then upgrading to a wireless n adapter would be a good choice. Alternatively, upgrading you're router to wireless n (if you're laptop is wireless n) would work too.
Wireless adapter of G type connect work in N type network. To take advantage of N networks you need to have N type network adapter.

If you are talking about building of wireless network. Then you need a wireless router and a wireless network adapter (if you have a laptop you might not need it).

You can't. You will need to purchase a new router.
