I'm using PiHole as DNS/DHCP server for ad blocking. Had it fail on me, thus taking down primary DNS and DHCP services. When I set up a backup, the Deco's continued to use the old DNS IP addresses, thus apparently failing their Internet self tests and leaving my WiFi network down.

And I had no way to tell why the self tests were failing or what was going on until I set another device on the same Ethernet network with the old IP and started sniffing packets.

If the app displayed two simple pieces of information this would have been much easier to diagnose:

One, along with the IP address, tell me the DNS IP and while you're at it, default gateway.

Two, tell me WHAT TEST FAILED and what the error message was.

Of course, the root problem is not honoring new DHCP settings, which should also be fixed, but in the meantime, this seems pretty trivial.

Thank you.
