Apple MacBook (13-inch, Mid 2010) - Manual (Page 65)

65 Chapter 4 Problem, Meet Solution
 Make sure your MacBook is within antenna 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 the signal strength is weak, 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.
