Internet dropping out intermittently in hot weather (maybe?) TONS of uncorrectables
I've been having a problem within the last 2 days where my internet has been dropping out for a couple minutes at a time. I thought it was my modem going bad, I've had it for a few years now (Arris Surfboard 8200, HW rev 4 bought 7/2018) but I decided to do some more digging because I couldn't tell if it was my modem, or my router that was the cause of the problem. My router is a Linksys EA9500 (bought 1/2018), with 6-12 devices connected at any given time.
I obviously took the first steps and unplugged the modem, still had issues, then same with the router with no change in the internet dropping for minutes randomly.
I connected to the UI of my modem, and saw this:
Needless to say, I didn't think that this looked right! I'm certainly not an IT pro, but even I know based on my research this doesn't look good, 24 hours after a restart. But, maybe I'm wrong, a restart may not clear the values of the corrected/uncorrected packets and this is for the lifetime of the modem? The power seems to be OK, ch1-3 look a little low, but not terrible. The SNR looks ok from what I've read.
Anyway, I did a reset on the router based on some other things I saw online, and then 3 minutes after I did a reset, I took another look at the UI and I saw this:
30 minutes later:
And 2 hours later from the last screenshot:
Here is a screenshot of the logs, which may or may not help.
I have checked the connection, the cable on the modem and wall is tight, no kinks, it has been in the same spot since we moved in. Really the only difference is that it has been very hot outside recently, and that is really when I've been noticing the connection issues.
Tonight, I'm going in the basement and tracing the line back to the ingress into the house to check for any splices and ensure they're tight, and I'll check the main house connection. But other than that, do you think this is a hardware-related problem or a problem with the line somewhere?
Now, one more item, I read somewhere that I should be sure to tell Spectrum to send a DOCSYS 3.1 signal, not the 3.0. But, I did give them the model and MAC so they could add it to my account, so I'm sure if it was that important it wouldn't have worked at all when I started service after we bought the house? Again, just trying to give all the information I have.
Thanks for the help!
