Very low download speeds with Gigabit

My iMac is hardwiwred to the xFi gateway (about 24"). I am getting 800-900 Mbps down, but only about 2-4 Mbps up.  BTW, service recently has been "sketchy" in the area. I've seen trucks down the street for 2-3 days this week.

Are you trying to compensate for all of the Zoom stuff going on?
