I just installed Deco XE5300 (3-Pack) from Costco tonight to replace my Orbi RBR750.  I'm no networking expert, but know enough to get everything hooked up and running.  What I can't understand is why the Deco app is showing horrible internet speeds, yet everything appears to be working great and my Speedtest.net is ~600mbps.

Hardwired to my laptop, I'm getting about 920mbps and I have 1Gig internet from Xfinity.  See the photos below and please help me understand!  Photo of the Deco app below and the Speedtest.
