A Wireless Router and Acces Points

Every people around me is talking about  wireless router, but I don’t knot what does it mean?  A friend explained me about the topic;

“A wireless router could be a regular IP router with an 802.11 interface card and antenna added, or it could be a router specifically designed for wireless use. Most wireless routers also act as firewalls, switches, and provide Network Address Translation (NAT).  If network speed is important to you, be sure to purchase an 802.11a or 802.11g wireless router. If you are comfortable with 11Mbps, save money by purchasing an older 802.11b wireless router.  If you need to increase the range of your wireless router, consider upgrading it with a better wireless antenna.

But, where I can find it?  My friend told me just search on Internet and you’ll find a great site offering everything you need in daily life.
