I have submitted a ticket about this - but it would be nice to see if anyone else has had similar issues or whether this is an isolated case.
When my ECI modem has been connected for a few days, all of a sudden the connection will drop. When this happens, the modem will automatically re-connect, but with massive latency and really slow throughput. It will then be in this broken state until i turn it off and back on.
It's not hot, so I doubt it is overheating, and it does the same thing with a different router attached to it, so I can rule out the router as the issue, which I didn't think would be the cause as I don't need to restart the router to get the connection back to normal, I only need to restart the ECI modem.
It seems to be getting worse too.... When this originally started happening, it would last a few weeks. Now, it lasts only a few days.
