Many thanks Poe...

I am pretty much sure there isn't an issue... After reducing the interval to 5 seconds its now been pinging 8.8.8.8 with zero packet loss for the past 6 hours.

I did bring up a graph by accident of an intermediate hope which has the odd dropped packet.. But its so infrequent that the loss still shows 0%

So I am pretty sure that I will simply sending too many pings.. And now I have slowed it down to the same rate as a "dos" ping it looks good.

Thanks for taking the time to reply.
