High packet loss on two seattle nodes

I have been experience very high packet loss on two specific nodes in the greater Seattle area that is making online gaming nearly impossible. I have attached the traceroutes for multiple servers include chicago, virginia, and seattle. All 3 of them have xfinity/comcast servers dropping very high amounts of packets.

These nodes are on IPs [Edited: "Personal Information"]

The target hop in all three traces received all of the trace packets, so the "loss" or "delay" at the intermediate hops is likely more apparent than real, and probably not significant. Please see https://www.dslreports.com/faq/14068.

Interpreting trace results is tricky. What appears to be "late" or is reported as "lost" could mean 1) the packet did not reach or was delayed in reaching that hop, or 2) the router at that hop didn't reply or was slow to reply, or 3) the reply from that hop didn't make it back or was delayed in making it back to the trace program.

The fact the hops beyond than ones you are concerned received the trace packets indicates that the router at that address is doing its job: forwarding data packets. That means the router's occasional delay in or failure to respond to trace packets, while annoying, is most likely not actually slowing down data transfer. If it was we'd see high RTT values and/or packet loss in subsequent hops.

Interesting, well it certainly feels real in games. The games internal network tools are also detecting the same packet loss and it results in a horrible experience with rubber banding and teleporting. There is also other information on this forum about these two nodes causing issues for others so it does seem real.

@BruceW​ is there another way I can confirm this is real or try to pinpoint the pack loss that I'm experiencing in game?

Are you connecting over Wifi? In any event, 129 ms ("worst" in third image) is an awfully long round-trip time for packets to travel from an in-home device to the gateway and back. That number should be single digits at most. You might want to look into that.

Interesting, yea that does seem high. I am currently on powerline because my apartment doesn't have Ethernet through the walls but I'll try running an Ethernet cable to my PC real quick and checking if that solves the issues. Thanks!

I switched to ethernet and unfortunately am still experiencing the same issues, very measurable and noticeable packet loss in game. I have attached another screenshot of me tracerouting the game server address and this time it is a slightly different server but still the same issue.
