I've had an issue with latency for the past several months. I've had 2 techs out, but my line came back clean. One did send a request to maintenance to work on my node because it showed something which I was hoping would fix it but it didn't. Below is a couple examples of what's going on, I've pinged Google and the first hop after my modem for reference.

I generally notice this when playing games and a latency variation symbol appears, buffering when streaming, or while trying to work and VOIP apps have issues. This issue seems random, but I do notice it more during the day, though it happens at night as well. My modem levels look good according to Comcast. Any help is appreciated.
