High Packet Loss / High Ping Issues

Hey everyone,

So I’m a bit frustrated here. I’m a gamer/streamer and I’ve been having extreme packet loss which results my ping to sky rocket while gaming, which causes me to lag extremely. I’ve been having this issue for months now. I’ve done all troubleshooting. I’ve gotten the my modem swapped with Xfinity about 4 times now and this is still an issue.

This makes most games nearly unplayable. My ping randomly shoots from a very stable 30 ms up to 120-150 ms for a few seconds and this happens very frequently.

For reference, the plan I have with Xfinity is for 200mbps. I’ve contacted Comcast various times and it hasn’t been very helpful. The customer service agents that I speak with don’t seem to even know or understand what I’m talking about. I had an inexperienced technician come over which all he did was change the heads on the coaxial cables and swap the modem. He basically had no idea what “ping” or “packet loss” even was. And after going through all this, it’s still an on-going issue.

How can I go about fixing this issue? How can I go about getting help from experienced technicians and/or Xfinity agents that know how to deal with an issue like this? I would greatly appreciate any help that I can get with this.

Thank you.

Did you ever get a solid answer or solution? None of the techs I called could tell me the real issue because it was actually something they didn't know about. I saw a couple of guys from Xfinity working on the street equipment and they told me a new node was being installed. It turned out to be a bigger issue that I could not solve my self and was network congestion.

Honestly, it is probably network congestion. I have been having the problem for 3 months, and when I saw some techs working on the street they told me a new node was going in. They said there was a ton of traffic, especially with the pandemic.

I wanted to chime in that I'm experiencing this exact same issue and it is very frustrating. We cannot use WiFi calling at all during the daytime which is important for work (not great cell reception) and online games are unplayable. This used to happen on and off in the evenings around what I'd call "peak" times but ever since the COVID stay home guidelines have been in place a few weeks back it is a constant issue during all waking hours. 

 

Look at this ping I just did to 75.75.75.75. I have seen as high as 1300ms during the daytime. If I get up at 5am and do this the response times will be around 20ms as expected. If you start measuring it around 7am you can pretty much watch the issue start happening around 8am as you assume everyone is logging onto their VPNs or online learning.

Hello i am seeing the same exact issue as posted in this thread.

Comcast tech came out today and supposedly replaced the line from behind my housE(alley) up to my house.  But i am still seeing pings in the 1000+ ms response and dropped packets.
