Arris 8200 overheating and cutting "thermal throtlling"
We have the Arris SB8200 with the 300 MB/S plan and starting in late march started have intermittent issues where our internet would drop for a few seconds every 10 minutes or so which is not acceptable for working at home. I have gone through the logs and the the snr downstream (37.8-43.4)/upstream (39-41) power levels seem fine downstream power between 37.8 and 43.4 (channel 48 is at 37.8 and is the only one below 41.1).
When I go through the event log I see these:
above these is a EM-RSP received, Reject Permanent (I am cutting out the mac address)
| 05/04/2022 22:32 | 2436694080 | 3 | "THERMAL THROTTLE: Temperature 93C, transition to state 'Normal'" |
| 05/04/2022 22:32 | 2436694080 | 3 | "THERMAL THROTTLE: Temperature 96C, transition to state 'Elevated 3'" |
It worked fine from November until March and now seems to be ok as long as I have a fan blowing across it. It sits unimpeded on a desk and has no airflow issues.
We were asleep when it had these issues last night so there is no way it was a loading/use issues.
Chatted with Arris who says it is the upstream power levels being too low - they are around 41 and Arris says they should be between 45-51. From what I have read this is [Edit: Language] as it is when those are too high that there might be issues.
My wife is not happy with the fan solution and I just want to know what would cause a modem to overheat regularly like this.
Any help would be greatly appreciated, all my searching is not finding any answers.
