Google dns weirdness

I was implementing some suggestions from Fraser tonight, and in the midst of everything I ran into a new (not netduma related) issue. The ps4 reported that I didn't have a DNS connection. I noticed I had left the custom setting for google dns in my wired internet setting. I do this every time there is a large update to download on ps4 (and yes, I know DNS doesn't affect speed - however I've used this trick more times then I care to count and for large downloads, for whatever unknown reason (maybe just path routing?), it has a massive & measureable effect) Anyway, I blew that out and it connected just fine with my isp's dns.

 

However, being the curious type I ran the internet diagnostic on the netduma as I know they ping the google dns server. Last night everything was fine  - tonight's results are below along with ping plotter results. This is the first of many test I've run over the past week since I received the netduma in which I've seen packet loss, let alone the weird google dns results.

It looks okay to me, you are getting a little bit of packet loss. This may be to do with your line. I'd keep an eye on it and see if it persists. Perhaps download Ping Plotter and run some tests over different times/days to see if it carries on
