      I seem to be having an issue with my SG-3100 connected directly to my spectrum modem where the bandwidth is pegged at exactly 50Mbps and seems to be capped. When connecting PC directly to the spectrum modem i get between 200 and 225Mbps every speedtest i run. I was previously on AT&T fiber 1G/1G with zero issues. Has anyone experienced this issue or can point me to a remedy?

      Thanks!

        Might be a MAC address lock limiting speed to anything but what was first connected if that wasn't pfSense?

        Check the Status > Interfaces page for errors or collitions on the WAN.

          Router was the first device to be connected to the Spectrum modem. I did call into their tech support and they "re-activated" the modem while my PC was plugged in directly so I'm not sure if that matters. I checked the status and no errors.

            Try testing from the SG-3100 dircetly to be sure it's a WAN side problem. You can do that using the speedtest CLI utility like so:

            [2.4.5-RELEASE][admin@fw1.stevew.lan]/root: pkg install py37-speedtest-cli
            Updating pfSense-core repository catalogue...

            The modem may need to be reset against the SG-3100 MAC though if it was done while your PC client was connected to it.

              @stephenw10 you solved it. Swapped ethernet cable from my switch to an LAN interface on the SG-3100. I must have a switch issue. Thank you!
