I don't know if my experience will help you, but here goes. I had 3 Basic Fire Sticks. The network is Google wifi mesh. The Fire Stick was 3 feet from the node. Everythng was working fine until one day it played about a minute of recording and then reported that my connection was too slow. Restarted the Fire Stick with the same result. Moved another Fire stick in its place and it worked fine. I assumed that the Fire Stick has failed so I ordered a replacement. Once I had 3 working again, I tried a factory reset on the "defective" one. Everything worked fine again, even further from the mesh node.
