Constant lag spikes and latency variation daily

@XfinityRay​ Well the issue happens whether I'm gaming or not, but it is only really noticeable when I'm doing something that depends on low latency, such as online gaming, discord voice calls, or work meeting via zoom. 

As for my home network, my main PC is wired via ethernet cable to my router, and it is on this computer that I notice the issue while gaming.

I've started running PingPlotter to keep a record of how bad the ping gets. Here is an example of when things are working normally, and the ping sits at around 30ms:

Then this start to get really bad, and games become essentially unplayable. The ping starts jumping around like crazy, hitting several hundred milliseconds for minutes at a time:

Hey @XfinityRay - I'm experiencing the same thing in Central NJ. I don't see an option to send a direct message and general support inquiries have been ignored/dismissed.

To piggy back on @dronfim 's post - my internet service is behaving similarly. Rough context below:

* For the most part, the internet is stable, but ping spikes will frequently occur in intervals of every 7-20s. (i.e. the average latency will be ~20-30ms, but then spike to 300-500ms, then come back down and repeat the cycle)
* I notice this mostly on VoIP or Video Chat meetings -- I work from home so this is painful for me. The issue manifests by freezing and hiccups.

* This can also be problematic when remoting into virtual machines or development environments (as the connection often drops me)
* I use a current desktop machine, plugged in directly to the router with a Cat5 cable. I don't have any additional security software, VPNs, anti-virus, or competing applications running. Confirmed current drivers, firmware, and Windows updates.
* I've tried replacing the physical cables and even replaced both the Modem and Router with newer models.
* Anecdotally, when running traces, be-98-ar03.plainfield.nj.panjde.comcast.net seems to be a problematic node with frequent high ping spikes and/or relatively higher loss %

Any information you could provide would be great, I've tried to be patient and tolerate the issue but its progressively getting worse instead of better.

@racerxow, We would be happy to assist you. Let us know if you are still having issues with your service.
