Exactly what I am suspecting! I called so many times: nothing found all works as expected.
As for the starlink: I noticed that clouds or weather ( rain snow ) does not have a true effect. Must be the frequency is not absorbed by the water in the air or similar effects. Only hard blocking with construction or big canopies of trees is struggling.
Then you call their customer support, tech comes out, it's not raining anymore and everything works, and the problem doesn't get fixed.
