I have a couple questions because I am by no means a networking expert.

I recently purchased the Deco X4300 Pro Mesh System and have everything bridged from my Xfinity router with the 1000mbps plan.

Now, everything is working pretty well. Speed tests show 500-700 mbps over wi-fi throughout my 2 story home. But when outside on the porch I get dropped from the wifi on my Pixel 7 often. Even though my main router is directly on the other side of the wall in front of a window. I also have a second router in my garage placing me in the middle of two satellites. Not the end of the world but frustrating at times. 

Also, even though all speed tests are great my app shows crazy abysmal numbers. 

Am I reading this wron, being nit picky, or is somethine set up wrong?
