Constant Internet Speed Reduction after 9PM Every Night
For the last month, I've been getting abysmal speeds at night (10 to 30mbps) when I pay for 200mbps. I get constant disconnects, and modem restarts. I've been in contact with Comcast at least a dozen times at this point. I've had techs come out and replace all the lines from the road, every splitter, and I've replaced my cable modem. Techs are coming out Thursday to look in the neighborhood (hopefully). I've been measuring my speeds every 30 minutes (while awake) for the last 4 days. Almost exactly on the dot, around 8:15 I'll start to see my speeds steadily start decreasing from 230mbps. At 8:15 they'll go to around 80mbps, 8:30 40mbps, 8:45 30mbps, 9:00 20mbps, 10:00 10mbps, and when I wake up in the morning the speeds will be at their lowest running at around 5 to 8mbps, until magically around 8:30 to 9am the speeds will jump back to 230mbps, then rinse and repeat.
I'll also mention that Xfinity supposedly had an advanced repair team look at the issue, and they just closed the ticket without letting me know the solution or what was done. Issue surely wasn't fixed.
I've posted a pic of my current cable modem (Arris Surfboard) status as of 10:50pm on 4/13/2021. I always notice Unlocked channels, and large amounts of uncorrectables while having these issues. Can someone help me here, because the multiple xfinity agents I've talked too have been no help.
