On the homelab front there is a Plex server that is fed movies/TV via Ombi/Sonarr/Radarr.
That is in your internal network.
Your downloads will take place at a specific time. Mine is usually from 12 to 7AM when everyone is sleeping.
So I don't see why 200MB is needed. Maybe your devices can connect via the 5GHz band on your internal network.
What am I missing here?
