Connection Drops with Logs/Stats
Hi all,
I'm having issues with my connection dropping over the past couple of weeks. It's gotten progressively more frequent. I'm using a Netgear CM1200 modem. Here's some of the stats and some of the logs I captured shortly after a disconnect.

It generally seems like 1-3 channels have a lower SNR with an accompanying high number of uncorrectables.
