I’ve never found any solution to this so far. I tried to put the echo alone on wifi access point on router, and while it seemed it happens less often, it still did. I just keep telling myself it’s no big deal and when it happens (usually when I try to show off my “smart” home) I just fly into bout of seeing-red rage and on the whole find the entire process quite cathartic /s
I wonder does anyone that encounters this use some sort of ad-blocking? I’m using pi-hole and wonder whether alexa tries to send some spy info every now and then with the request, and times out since the address is unreachable. Not really willing to test this though, as even if it was the cause, I ain’t giving amazon any exceptions in pi-hole.
