DNS issues can occur in multiple instances. LAN DNS issues can occur when certain devices or websites cannot authenticate the AmpliFi router's default DNS. DNS issues over the WAN port can occur due to the router not being able to authenticate the ISP's DNS or if a preferred DNS was specified incorrectly. To learn how to change the DNS on AmpliFi, please see this article: Changing the Network's DNS Address.
Changing the DNS may be necessary, this article will show you how to change it.
Make sure the router is not in bridge mode, since that will disable the DNS configuration option.
