I read a few posts that seem similar to mine, but thought I would get some insight before calling TWC/Spectrum. I would much rather find and fix the issue myself.
I have come home twice in the last week to find no connection to the internet. That usually happens to me about 2-3 times a year. I simple reboot of the modem does the trick, but I picked up on a trend a couple of days ago I had not noticed before. My internet in the evening (7-10pm) seemed sluggish. Especially from 9-10pm. I have been running periodic speed tests and noticed that during the morning or early evening I am getting my usual around 68-70Mbps. I pay for 60 so I am usually estatic and have not had any issues. Now it seems that starting around 6pm that starts to trend down to the 30s and eventually dips into single digits around 9pm and stays there until after 10. I never stay up late enough to see when it recovers, but at 6am the next day it's back around 68-70.
I checked connections, disconnected all items except those being used for testing, bypassed my WIFI router, checked for tight connections in the attic, etc..., but then went into the modem and sure enough found an error log starting about the time I can remember having an outage. Some of it I know is from me playing with it. Wondered if any of this is off or what it might mean? I live in a new subdivision, but service has been built out for about 2 years. Modem is a Netgear CM400. Thanks in advance.
Do you have any sort of cloud backups, scheduled updates, antivirus, etc. running during the times of the slowdowns?
I thought about that too, but no. I bypassed the router and connected straight to my ATV4K and then did it again with my Mac with a different CAT6. Same results either way. Maybe it has been going on for a while and I just didnt notice it until I started dabbling in 4K 2 weeks ago.
Thank you again for the assistance. Here you go. Did not seem to help, at least running a speed test. Looks like about 9pm it just hits a wall. I tested about 8:30 and was getting mid 40s. Not upper 60s, but good enough. At 9pm and just now I am down to 8-12. It spikes into the upper 30s and then drops and levels out at 8-12 right now. I also took the wall plate off and tightened the connection behind. It was hand tight, but solid. Tried wiggling the cable too during the test to see if it was a badly made up head. Just throwing darts....lol.
Here is current while it seems to be working at about 75% speed.

corrected and uncorrecteds didn't increase so it appears it's either one of your devices hoarding bandwidth or the entire node is slowing down.
Make sure you don't have cloud, sync, onedrive or win 10 peer upgrade running on any of your devices...
