@d0ugmac1 In my case the latency goes to 0 and back up over and over creating a razorback as seen here:

Yours floats nicely above the through put, mine interferes (as you can see). The ISP has latency that runs as high as 800ms so there is a big swing. I'm going to address that with them in a separate ticket with the provider but this shouldn't look like this either.

As mentioned in your other post - upgrade your OC300 first.

And then try using different latency servers for measuring to see if your latency graph becomes a bit more 'straight'.

Instead of 'Default' you could use e.g. 8.8.8.8 and see how it goes.

  @Hoamboy I have changed to google nameservers as per your suggestion and will see what happens - I'm not famliar with "latency servers" but I presume you mean DNS servers, which are blank by default so they'd use whatever server the OC300 gets from DHCP I suppose. I will advise.

  @OrangeStreet 

Sorry for being unclear.

Yes try Google DNS servers 8.8.8.8 and 8.8.4.4 and play with online connection test settings described e.g. here:

And of course make sure all devices are running on latest firmware.

  @OrangeStreet Switching to the Google DNS servers did the trick, the default DNS servers chosen by the default omada configuration must be terrible. Thanks!
