About a year and a half ago I had pretty intermittented packet loss every evening around the same time, took a few months to get this resolved ( was not an issue on my end, upstream noise issue was what I was told in the end). Now I'm having similar issues, except this time it's just really bad ping spikes.
This makes most games nearly unplayable, randomly shooting from a very stable 60ms up to 80-120 ms for a few seconds very frequently is a huge pain.
What is the best way to resolve this? Given my net is 100% fine for most of the day I'd assume it's a similar issue as before where I'm basically sitting on my hands waiting for Comcast to recognize there's a problem and figure out where that problem is. I'm just unsure how to help in this process.

Solved! Go to Solution.
Is this with a WiFi connection ? If so, for a test, does a computer hardwired directly to the router / gateway device with an ethernet cable have the same problem ?
What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 or here http://10.0.0.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
What is the exact make and model number of the modem ?
The signal stats looked o/k at that snapshot in time. Please also post the RF error / event log entries from the modem.
Even though the signal stats looked o/k at that snapshot in time, the error log entries confirm that something is going on. Perhaps there is noise ingress into the line(s) somewhere.
There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They can check the CMTS (Cable Modem Termination System) for any real time degradation and / or error reports, see your node / cable plant and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.
You should get a reply here in your topic. Good luck !
Hey there s7efen,
Thanks for posting your signal levels and letting us know about that high ping you've been experiencing. I know how important low ping values are while gaming so we'll take a closer look at your area to get to the route of the problem. Based on your logs you've posted, I would agree with EG and say that it sounds like there might be noise on the line but we'll confirm in a bit.
