I'm working with a 3rd party surge protector that can auto-reboot outlets based on Ping timeouts. A common setup is to ping google, yahoo, etc. and after a defined number of time outs, the modem or router is automatically rebooted. Through the course of troubleshooting a client site, we determined the cause of connectivity issues to be a DNS error. None of our wired devices (Sonos players, surge protectors, managed switches) experienced any problems, but all our Wifi clients couldn't connect to the WAN. (There aren't any wired computers on site). My thought was that the router would use google DNS on the WAN side (it receives IP through DHCP) and DNS proxy for the LAN devices. All media, network (Unifi AP-AC-LITE) & client devices were set to use the router's DNS table. The thought was that if the router were to experience any DNS issues, it would trigger the ping timeouts on the surge protector and auto-reboot. This hasn't been the case though...So what's the best practice for setting DNS servers at the router, WAPs & other network enabled devices?
