Apple Mac mini (Mid 2011) - Manual (Page 61)

61 Chapter 4 Problem, Meet Solution
 Make sure your Mac mini 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 your
Mac mini or the other computer might improve reception.
 Check the Wi-Fi status menu (Z) in the menu bar. Up to four bars appear, indicating
signal strength. If the signal strength is weak, try changing your location.
 Choose Help > Help Center, and then search for “Airport.” Also see the instructions
that came with the wireless device.
