That was my thinking as well. I just need to dedicate the time to troubleshoot this. It plugs directly into my GbE switch, so it should either be the cable or the port, I assume. PfSense is reporting a 100Mb connection, and I’m seeing a max of 11MB/s throughput, which is consistent with that. I’ll try to avoid derailing any further.
