Re: Change in channels
your downstreams will always be qam256, they have been for years and need to be for the throughput. You will never see them drop to qam128. Keep an eye on your upstream channels, qam64 is better than qam16 (by 50%) and having qam16 on 4 channels is by no means the end of the world. It is possible you have been moved to a new bonding group (you would need to look at the channel numbers) or more than likely there is some noise on the line and if you check back tomorrow or the day after they will revert to qam64.
