Recently setup a rt-ax86u pro and have noticed our iOS devices show privacy warning occasionally under WiFi, describing something about sending dns unencrypted, more often than my old router. I have scrubbed the net and can’t find a qualifying definition as to why this happens. Forgetting the network and reconnecting solves it for a while. I read that sometimes it’s a router config issue but I do not have any type of parental controls and dns is automatic through ISP. Is this anything to be overly concerned about? Is it the router or my isp?
