Significant Packet Loss

I am experiencing a significant Packet Loss issue, during Online Video Gaming, which is happening with my 1.2Gbit internet service which is using a Xfinity XB10 modem/router.

Currently, I have an Ethernet-wired connection direct from the Xfinity XB10 modem/router to my tower PC.

user_m2h8nn, Thanks so much for reaching out to Xfinity support. I know packet loss while gaming can be frustrating. Here are a few things that will help. If you could run a ping test to Google (8.8.8.8) to isolate the issue from the game's server. If the packet loss exceeds 5%, please document this. It is good to test on at least two different devices, preferably close to the access point, and avoid using gaming consoles for speed tests due to the variability. Record relevant data such as signal strength and location. If your speed appears to be fine, then monitor and record issues. We can run through some troubleshooting steps with you as well. Please reach out when you have some time to work with us.

@XfinityAngie​ I've done a command line ping test from my PC to 8.8.8.8 for 2 hours, and my packet loss is at ~4%. This has been done with the PC directly connected to the Xfinity Gateway via Ethernet cable. I've tested on my Mac work laptop, with packet loss ranging from 0.1% to 2%. This was also a direct connect via Ethernet cable. Since these are wired connections, signal strength/location is not applicable. Speed tests from these devices show we're getting ~850 Mbps down speed. The packet loss is not constant, and instead happens in 5-10 second "bursts". These bursts occur within a variable period of 20 minutes to 2 hours apart.
