500 MBPS point to point

We have a 500 MBPS point to point that runs from our main office to our backup site. We have been struggling for a while now trying to figure out why we can only get 60 MBPS out of it. We have had Spectrum test the line several time and everytime they show it is running 500 MBPS.

We have forced the duplex on the firewall and nothing.

We have tested with 2 laptops and we get the same results using iperf.

We are looking for some ideas on where to go next.

Thanks!

Dave

Hey Dave,

What speeds do you get if you connect two laptops directly, leaving the UTMs out of the picture?

It has to be on the Spectrum side. If we connect directly to the spectrum equipment the problem still exists.
