Constant packet loss - living in apartment complex using xfinity modem

Hey,

Located in the Palo Alto area and been on support and restarted, disconnected reconnected many times but nothing fixes it. Around 15-20% packet loss consistently making most games and many services unusable. Don't have any special router or setup, just the modem wireless that came with for wifi for the whole house.

Technician replaced coax cable and comcast modem, seems like that was the issue as now I am not seeing any packetloss. Thank you!

Thank you for reaching out @jl.m1. I am sorry to hear about your gaming experience. Are you using an ethernet cable to connect your console to the internet?

Yes, I am using ethernet connected to my mac mini directly to the modem. The packet loss I tested was the same whether on wifi or ethernet

By the way the steps I've already taken:

- On call with support restarted modem using xfinity app multiple times, plugged and unplugged coaxial cable, unplugged ethernet and reconnected.

- The test was conducted using packetlosstest.com with default settings

- Test is consistent across multiple devices including macbook, macmini (eth), iphone(wifi), tv streaming stick, console, smart fridge, etc etc

- No additional routers, VPNs or anything that modifies/redirects internet traffic

- I have asked support to come in person to diagnose several times to no avail

- Wifi speed is consistent with what I pay for, only packetloss is an issue
