I have a similar problem to this.
I get in a situation where the app says that it's connected, the statistics show ok latency, but usage will only show .01 mbps. I can't get a connection. This usually manifests itself in the morning after the dish has rebooted for an update or other reason. In order to resolve it this morning, I had to reboot the dish 5 times. After reboot it will likely show connected, but .01 mbps, sometimes it will say that it can't connect to the dish, and if I'm lucky it will work normally.
In the past when this has happened, I have left it showing .01 mbps for several hours and it never improves until I reboot and it connects propertly.
I've been in contact with Starlink and I've received a new router, cable and ethernet adapter.
Any other ideas?
