Advertisements One: disable IGMP Proxying Two: disable QoS Three: MoCA would be better. I use a R8000 and never have a Mini issue. I usually have one and sometimes three Mini units on-line. The "stutter" issue can be duplicated by using a slow connection. The QoS logic can slow down a connection. A reboot of the router stops the slowdown for a few hours. Also, my R7000 and R7500 had disconnect issues.
