This issue started about a week ago. I noticed weird dropouts/lag bursts and then saw a crazy high number of uncorrectable codewords in the SB6183 (modem) status page.
So I began actively monitoring to document the issue (screenshots below). Should I schedule a technician now or ride out the storm? I am currently on the Ultimate internet plan with the Cox Service Protection Plan.

Packet Loss
Since this forum can't handle images well, please click on them to see what I'm referring too.
First, FYI, reason images don't fit is there is a max size that can be handled. I think it's 400x500. Not a big deal though.
Second, how comes tracert is missing hop 1 data?
Last, your upstream is on the low side. May be prone to intermid. interference. I needed a filter on my modem because the connection was direct from the street and my signal was TOO high. What do the logs say?
Here is another incident:

Packet Loss:
Again, why is tracert missing first hop? In the first part it shows some latency spikes but then doesn't include it in graph. Need to isolate if issue is modem>router or modem>cox.
Also, can you please post the logs? Specifically from around the time the packet test showed the most packet loss.
It's not missing the 1st hop - it's not shown because there is nothing to show except a flat line. There is no issue with the connection between my computer and router. It's plugged in with an ethernet cable, end of story.
The logs show nothing at the time of the connection issue.
The table below contains the log of events that the SB6183 has detected. This log can be important to the service provider to help diagnose and correct problems, if any should occur.

No packet loss on my LAN:

It's not missing the 1st hop - it's not shown because there is nothing to show except a flat line.
Then how come it showed in the test above? I didn't think there was a problem on your network, I was asking why the data was missing. Since the new image shows everything good, consider it moot.
The logs are interesting. The first thing I see are T3 errors through out the log. Those aren't good, but they don't tell much about the problem. Next, and most importantly I see T4 errors, without the usual T3 errors next to them, and MDD messaging. This makes me think the channel ID's are being juggled to maximize throughput, which you sometimes see when the node is congested. When the channels change, they probably occur uncorrectables. This is all guess work, so take it with a grain of salt.

Hi Vegas50000,
Your upstream modem levels aren't where I'd like them to be. I suggest we schedule a service call so an on-site tech can resolve this for you! Send an email to cox.help@cox.com with a link to this page, your full name, and address. We can get a service call scheduled for you.
Thanks for checking! I have sent an email to setup a service call.
