Hi. I have the 400Mbps plan and just recently got a SB8200 hardware rev 6 (firmware AB01.01.009.36.02_022720_183.0A.NSH). I am getting a lot of corrected error on channel 29 with locked status but showing Modulation as Other instead of QAM256. Nothing out of ordinary from the event log. Is this normal?

    johnd3, I have the same thing on my SB8200. I suspect that is an OFDM channel. I recommend you open a support ticket and ask Arris what that is. Is you Down Stream LED on the front BLUE? If so, that means it is OFDM. I think the modem is great, but their understanding is poor and the statistics are not good. Statistics are much easier to read if pasted as as a screenshot not a copy. Thanks and enjoy, John.

    Yes. the front panel is blue so my understanding is it is running 3.1. But the "corrected" error keeps going up. since positing 8hs ago it is now at 4127809677.

    Mine too, johnd3. Now it is 19960873. Please ask Arris. Enjoy, John.
