Apple MacBook Pro (15-inch, Early 2011) - Manual (Page 63)

63 Chapter 4 Problem, Meet Solution
 Make sure your MacBook Pro is within range of the other computer or the network’s
access point. Nearby electronic devices or metal structures can interfere with wireless
communication and reduce this range. Repositioning or rotating the computer might
improve reception.
 Check the Wi-Fi (Z) status icon in the menu bar. Up to four bars appear, indicating
signal strength. If you don’t see the bars, try changing your location.
 Get help online by choosing Help > Help Center, and then searching for “wi-fi.”
Also see the instructions that came with the wireless device for more information.
