Packet Loss Constantly

I recently moved to a home but before I did I had packet loss issues while gaming on my PC at my apartment. I upgraded to the XB6 and thought my problems would be solved, they were not. So I figured when we move all the issues with network congestion and everything else would be solved. I had a technican come out, that I had to pay for, and he re-ran all the cable from outside to inside. I only have one splitter and it directly connects the outside to the splitter to the modem and then I hardwire into my PC.  I have done wireless adapters, new network cards, pingplotter, Network reset, etc. You name it I've done it. I recently bought a gaming router and will be soon purchasing my own modem. I was just wondering if anyone can see issues on my network from looking at the usual Up Down SNR. I'll paste that below. Thanks, hopefully I'm not just going crazy.

Huh ??? Things aren't like / don't work like that....

 

@kyle_ja05255 [Edited to match username, remove PII] The signal stats at that snapshot in time were ok / in spec. Are there any error log entries being shown ? If so, please post them as well.

You listed a bunch of settings that you can't change.

And it doesn't really matter unless you are on a satellite communications.

Your QR is like 690 millions which is fine for tune. Everything else is in negative Db because you share with your neighbors. And the same as wifi. They might provide a channel map for WiFi. For example my neighbors use 1 and 11. I fit mine in at channel 8 and I'm alone.

But, if you get a chance to change the volume of your internet settings go ahead. I use this for reference from room one to room 1408. 1:14 ratio. https://en.m.wikipedia.org/wiki/A_band_(NATO)

Yep. Those router component event log entries are unhelpful, unfortunately...

We've seen many posts here recently indicating that they have now blocked the end-user from accessing the modem component's RF signal error log entries in the Comcast supplied gateway devices. A BIG mistake in my opinion......

 

Perhaps there is noise ingress into the line(s) somewhere ?

 

There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.


I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They can check the CMTS (Cable Modem Termination System) for any real time degradation and / or error reports, see your node / cable plant and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.

You should get a reply here in your topic. Good luck !

We appreciate your patience, @kyle_ja05255 [Edited to match username, remove PII]. I'm sorry for the issues you're having with your internet. I wanted to check in to see if this has been resolved for you? If not, I would like to check for noise on the line or issues at the node that may be causing this. Can you send a private message with your first and last name and the numbers associated with your service address?
