Low bandwidth detection

Hello,

I see numerous post ( well maybe 2). but no answers.

Low bandwidth network is detected for Zoom Room

10 megabits / second. on a 1 gig port.

I am curious if  it can be better described if it is the Mac-mini or the controller that  gets the complaint?

Is there any other breadcrumb to help.  Our HG bandwidth is  hardly utilized so this issue seems more seasonal than traffic.

Is there any flowchart that  can be used to describe how ZOOM INC sends this error?
