I see that. I don’t think the problem is confined to Samsung or that it can be completed solved in isolation from fixing wireless AP router behaviour. At the edge of the WiFi network I also see the IPv6 connectivity dropping while IPv4 stays up. I’ve a ZyXEL home router that sends periodic RAs every 15 seconds and a Huawei home router that sends them every 1800 seconds. It isn’t production ready yet. Ross
