I do not think there is an issue. My router shows a constant run of data spurts passing through it all day long because I have 8 Dots, an Echo and two Google Homes, PLUS other gadgets that periodically check with their mother ship for any updates, etc. These things are not dormant for long. I also have Comcast, and my dual-band network works great. Relax and find other things to worry about, really.
