I am hoping you all can help me. I recently got set up for a gigabit connection with Mediacom and have been unable to reach high speeds consistently. I have an Arris Surfboard SB8200 with a Ubiquiti ERPoe-5 behind it, with my LAN connected through the router. I run continuous speedtests through a Docker container (atribe/speedtest-for-influxdb-and-grafana) but I have never gone above 733 Mbps DL, and my average speed over the last 13 days has been 480 Mbps DL. UL is avg 55 Mbps and max 69 Mbps, which is fine and what I am provisioned for. I understand there is networking overhead and my router should lose a little bit of the speed, but consistently losing half of the speed I am provisioned for is excessive. I would be satisifed with a consistent 750-800 Mbps DL. Even testing directly through the modem is only a little better.

I have several OS in use. My home server is running Ubuntu Server 18.04 but my laptop is using Windows 10. Everything is up to date.
The issue isn't intermittent, it is a consistently low speed over time. There are no applicable firewall or antivirus that could be affecting these results.

I like to consider myself reasonably tech savvy, so please give as specific and as technical an explanation as you are able. I would particularly like to understand the events in the event log, as I am not sure what they mean.
