Dotted lines in flow chart
My wireless network seems to be working fine but I noticed that the Airport Expresses I use to extend my network are connected graphically by dotted lines and below my Time Capsule within my Airport Utility picture. I'm pretty certain solid is hard-wired and dotted means wireless. The reason for my concern is that two of the three Airport Express units are hard-wired yet show they dotted lines. Is that correct or do I have a problem?
