Network Connections

ÂMake	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

computer	might	improve	reception.
	
ÂCheck	the	 Wi-Fi	(Z)	status	icon	in	the	menu	bar. 	Up	to	four	bars	appear,	indicating
