Ping Spikes / Latency Issues with Blizzard Servers

Hi All,

 

over the past few months I've noticed that I get consistent ping spikes while playing online games from the company Blizzard.  It will go from a normal 20-25ms ping to spikes of close to 60ms and cause severe rubber banding when it does.

 

I ran a WinMTR and it looks like the issues are on the Spectrum side; I reached out to Spectrum support and they are having a tech come out Saturday but after digging into it a big more it looks like the modem could be the issue?  I am using a SB6190 and wondering if perhaps this issue cropped up when my package was bumped from 100MB to 200MB speed.

Attached a WinMTR to one of the Blizzard servers below for refernce 

 

thanks in advance for any ideas!

Re: Ping Spikes / Latency Issues with Blizzard Servers

Your modem is a model that was designed using Intel's Puma6 chipset which displays serious performance issues.  Ongoing technical investigation taking place involves a class action lawsuit investigating whether cable modems containing Intel's Puma 6 chipset, including the Arris SB6190, contain a serious defect that prevents them from operating properly.  Reports on multiple websites and forums indicate that these cable modems suffer from "latency jitter so bad it ruins online gaming and other real-time connections."

Intel has confirmed the defect, stating that the company is "aware of an issue with the Puma 6 system-on-chip software that impacts latency," but after numerous months, has failed to release any update that fixes the issue.

 

You should seriously consider using the modem that Spectrum provides at no extra cost to your monthly internet subscription fee. 

 

 

The information beklow is copied from website approvedmodems.com:

Do Not Buy List - Modems With Puma 6 Chipset
Due to many issues with the Intel Puma 6 Chipset, you should avoid buying the following modems. The chipset has caused many disconnects and interruptions with service. Please understand that these modems are the only ones affected and shouldn't harm a manufacturers name. Most have started using a different brand chipset in newer modem models.

Yeah... that chipset has made quite a name for itself. Websites even have tools out there for testing the modems for the issue. Here is a link to the one at dslreports:

Yeah, deliberately using one of the black-listed Puma-6 modems is a lot like trying to run high hurdles with your ankles tied together.

Re: Ping Spikes / Latency Issues with Blizzard Servers

Well that pretty much confirms it then! Thanks for the feedback
didnt know Spectrum offered a modem without paying a rental fee; that was why I bought the 6190 2.5 years ago.  So the tech coming out Saturday should be able to give me a non Puma 6. chipset modem then?
strange how I never saw this problem  with latency until a few months ago, and I've been online gaming for the entire time I've had the 6190.  Could it be related to the free speed bump from 100 MB to 200 MB that Spectrum did a few months back?

Re: Ping Spikes / Latency Issues with Blizzard Servers

So I swapped to a Spectrum modem today - still getting the same ping spikes when running WinMTR - they gave me no choice but to take a Hitron Puma 7 modem...

Tech is still coming out tomorrow - not sure if there is any way to get him to swap me to a Broadcom Docsis 3.1 modem?

Re: Ping Spikes / Latency Issues with Blizzard Servers

Need to verify there are no localized signal quality issues... look at the signal page of the modem (If they ha en' t hidden it) to see if there is a high error rate, abnormal dips in signal strength and/or SNR values.

Gotta figure out why your first hop is spiking over 300ms.

Re: Ping Spikes / Latency Issues with Blizzard Servers

So tech came out - said there was a value that was too high he saw at the coax going into my modem - he put a new splitter on and values were within norm.

He was able to swap me to Technicolor modem from the Hitron which was good

 

still seeing the spikes on WinMTR but in game I am not seeing anything/ experiencing any spikes/latency issues like I did before

 

Can't seem to find anywhere where to check signal strength on this new modem though
