HooRU What about latency and upstream?

You can use MTR in Jitter display mode to one of the iperf servers so you can see jitter on the path to the speedtest server.

$ mtr -o “DR AGJMXI” speedtest.dal13.us.leaseweb.net –report-wide

geek

I like to run the jitter along with a bi-directional test with multiple streams at the same time to see what is really going on.
iperf3 -P3 --bidir -V -c ash.speedtest.clouvider.net -p 5203
iperf3 -V -c ash.speedtest.clouvider.net -u -b 1M -t 30

Also, those GUI tests don’t show if they are IPV6 or if they are using multiple streams, etc. Another lesson why your ISP should just be a dumb pipe. No tools, no e-mail, no security services. Because somehow they manage to screw up the most simple things all the time!

MacLeech

Good for end to end jitter, but leaves out the intermediate hops jitter. MTR may show issues in the path.

And one more ipv4. It looks like upload is a little choked if i’m reading it right,which is what i think we’ve been seeing.

Welp. To me it looks like the combo of IPV6 and upload is the issue. You could try to eliminate the Eero and go direct with a machine that you have taken precautions with (no physical drives, only booted from a live usb stick or similar) and test if you want to take it that far. After that….I’m out of ideas and would start thinking it’s a Frontier issue.

This is hiding in the test output too which could be something or could be nothing.

CPU Utilization: local/sender 100.3% (100.3%u/0.0%s), remote/receiver 0.2% (0.0%u/0.1%s)

Maybe start charting system resources during your tests.

To Ashburn or Secaucus latency goes from good to so so to even bad. To Dallas and all far away serverse, latency is as high as cable or worse much of the time. And speeds, as you can see, aren’t great on upload.

But it’s all over the place. Frontier/Verizon must be doing things but why aren’t they telling us and trumpeting future quality? Frontier communicates worse than my sister, and she’s awful leaving people the the dark and the lurch 3/4ths of the time.

Still not convinced it’s not a you issue. We need tests without the Eero.

I’ll say it again. The GUI test you are posting are almost worthless as they don’t tell us the test parameters that were used.

VZ has over 80k employees, I would hope they are all doing something. What are you expecting them to trumpet/say? I would rather they keep their mouth shut, advertising budget super low and run and expand the network.
