Bodybuilders say, "You can't fire a cannon from a canoe." This aphorism is used to illustrate the need to develop all muscle groups, rather than focus just on beach muscles, such as your arms or chest. It's also necessary to focus on stabilizer muscles, such as the core and lower body to fully realize your upper body development.

Don't worryyou haven't wandered off into a bodybuilding handbook. However, this illustrates an important point in the world of wireless networking: It's critical to recognize that Cisco access points (APs) and client adapters cannot do the job all by themselves. They rely on another component to get the job done: antennas.
