Loaded latency issues after upgrade to service.

[Cookies001]

i have posted before about the ongoing issues being experienced since we have upgraded service, issues that I have now detected to be caused by an extremely unstable/high loaded lantency problem that appeared alongside the upgrade to our services. 

on the low side we get around 90ms on the high side it will shoot up to 900ms. It's never consistent, tests done seconds from one another to the same locations (no matter what distance) will jump from double to triple digits.  
this is affecting every device as it's just the "new normal" for our connection.  Calls lag, games lag...everything lags. 
this was never an issue before the speed upgrade and move to the new gateway, this house was also completely new wire job last year.

This post sounds like it would be more appropriate in the Your Home Network Forum.

Why would you sell a service and force a modem what can it handle the throughput without these issues?

the ONLY solution is to use a third party router and limit your incoming and outgoing bandwidth....too which I ask, why even have this plan anymore if the benefits of paying for a higher tier are of no benefit? 

all I am going to do by solving this issue is restricting my speeds and going back down tomwhat I already had BEFORE the upgrade. 

the gateway provided by your own service doesn't allow for any QoS adjuesrment and gives us a loaded latency of 900ms, That's insane.  
pit results in dropped and garbled calls over voip and games that cannot even be played correctly online.  

I would happily go back to the old plan to avoid these issues, however it's going to cost us even more to revert back down now that we changed over.

I don't think any Comcast Gateway has that feature.  You can purchase your own Comcast-approved Gateway but I don't know whether any of them have the features you are looking for.  I have never really had any need for them snce I got TW/Comcast in 1982.

Personally, I put my XB6 in Bridge Mode and use the Orbi for my network.

issues persist with or without bridge mode and router involved.  Everything reads back the same issue. That being, Bufferbloat on our download side of things. 

Our loaded lantecy is being affected on the download side of things, the upload seems completely fine.  Download is spiking us all the way up to 900ms while under load and typically sits around 145ms while not under load.  

I've tried everything to solve this.  changed cables, bought a router of my own, limited download speeds....nothing works.  
Our download remains bloated with insane round trip ping times regardless of the device, connection type or self induced throttling.  
as stated, we never had this issue before moving to the new Comcast gateway and upping our speed from blast to the 300 tier.  

No amount of speed limiting on my end affects the high loaded latency we are experiencing.  I can drop us all the way down to 50 down and will still get a 150ms to 900ms  bloat on the connection, so it doesn't look like an issue on our end as far as congestion is concerned. 

when I call and try to reiterate the issue to Comcast, the people answering the phone don't seem to understand the issue.  They just keep trying to tell me my download speeds are fine, as if I'm talking about just my speed cap.  When I ask here I keep getting told it's our network that's causing the issue...my "network" consists of your modem plugged directly from the wall and a few cat 6 cables connecting a tv and a few game consoles....I'm beyond frustrated at this point. 

what is it going to take to actually have someone come out here and fix this issue that understands the actual issue?
