Starting 2 days ago, I've started to get intermittent disconnects that usually last between 10-15seconds. It's pretty annoying, especially when I'm WFH doing video calls and my connection drops (though the weird thing is that i'm able to still hear the other side's audio while they see me as disconnected leading me to believe I have an upload issue).
Anyway, I did the usual - Comcast support restarted my modem a few times and then verified that their connection to my home or tap is all good on their side. I also took a look at my SB6190 modem logs and it shows good SNR and POWER for upstream and downstream, but I'm seeing high "uncorrectables" which I've never seen before. Anyone have a guess at what's going on? Attached is a screen shot of the logs from roughly 30 min after Comcast reset my modem. During that period, I've had 3 disconnects of about 15 sec each.

The images you posted aren't visible. They all look like this:
It's probably because the images require moderator approval. That might take some time, from a few hours to a day or so. Alternatively, you could upload the images to a file sharing site and post links to them here, or post text instead of images.
I had a tech out last week twice fix wires replace connectors, went through my entire Netgear modem router and basically shrug with no answer as to why I am experiencing these drops. Worked for 4 days and now im getting internet drops like crazy today! WHATS GOING ON XFINITY HELP US... INTERNET IS NOW ESSENTIAL! dropped as i am typing this
FWIW, that QAM test should be automatic / SOP.... It's a shame that the average so called "techs" aren't more well trained.....
How do the so called *techs * not have access to everything that they need to do their jobs ?
16 and 15 what. Channels ? There's no difference there ?
There are no channel designations in the error log entries... They are not that granular, unfortunately..
So what about the frequencies.. ?
And the channel signal levels in the signal stats have no difference to talk about....
I see zero.
The channels are different frequencies.
So even if we are not, it's really insignificant anyway. There are plenty of other redundant downstream channels.. One or two with some bit errors won't have a significant effect on overall performance.
UGH.... Your problem might be your Netgear modem. I have had never ending drops, disconnects and slow connections. Of what I seen of reviews of my Netgear CM400 modem, lots of people are having similar problems. Seems to be the best solution is to toss the modem and buy another company's modem. Netgear does not seem like company with good customer support.
Dumb question - but do we as the end user control the channel the data flows to? The reason I ask is that every time I get an intermittent disconnect, I notice that the uncorrectables go up by a few to tens of thousands.
