Latency and Disconnections Related to Modems with Puma 6 Chipset

Technical Support
Prev 1 11 12 13
My apologies if this potential fix has been posted. I did not read all 12 pages of responses.

I have been playing WoW for 10 years and have only have the occasional high latency issues. Always related to a recent WoW patch/update. However, I have had massive latency for the last week - to the tune of 400+ms Home and 1000-3000+ms World. I have one of the modems on the list. (Wave Broadband / Hitron CDA3-35)

My resolution - I disabled IPv6 support in WoW via System -> Network -> Enable IPv6 when available (uncheck this, Exit Game, restart WoW).

I am now back to my normal and expected <50ms times for Home/World.

If I re-enable IPv6, my latency goes back up.

Hope this helps some people!

Try an ARRIS SURFboard SB6183. Worked for me.


He's using a TG unit, which is an all-in-one modem/router/EMTA unit. To move to the SB6183 he'd have to get a new router and ask for the ISP to provide the EMTA separately, which is a fairly large hassle depending on the ISP. They're required to do so at the customer's request in the U.S., but that doesn't mean they make it easy.

This person will need to ask the ISP for another AIO (gateway) device that isn't based on an Intel CPU, i.e. they need to find a Broadcom replacement.

This "fix" helps, but only if you aren't grouped with anyone overseas or from WoW's other datacenter (there are two). If you end up in a group with the group leader being based overseas or whose home server is in the datacenter opposite yours, your latency is still going to skyrocket due to how Blizzard's routing currently works. There's no getting around that. You'll see the effect as latency jumping approximately 7ms every 10-15 seconds until it gets so high you disconnect. The only workaround to that is to log onto a character on a different server (say, a connected realm) for a few minutes so your primary connection dies out, and then return to the original character and move on.

Obviously this isn't ideal in the least, but there's nothing we can do about it and Blizzard isn't inclined to work on that problem themselves at this point.
Better add ARRIS DG3270 to the list as it is symptomatic of all the others on the list.
So for everyone that is using the dpc3848v techinicolor cisco modem and the hitron from shaw they have a firmware update you can require from them and thats stopped all of my bad spikes i been having and the game has been running super smooth.

this is starting to get crazy it like ever xpac, it my modem or my router , or my computer , i have the TG862G Arris , i even change back to a older one the same prob happen over an over , this just started with this new patch/8.0 random freeze up people running in place , but im able to talk to g mates about everything


That isn't an issue with Puma 6. That's a world connection issue with your connectionto Blizzard. Home latency refers to Battle.net, while World latency refers to the game world itself. That's why you can talk in guild chat but not actually interact with the game world. You need to start your own thread as your issue is not caused by the issues present in the hardware listed in this thread.


Thank you. I was about to ask about this very issue as I've been having extreme latency issues since the last hotfix. I can talk in guild chat--no lag in communication. But I cannot do ANYTHING gameplay-wise.

These are my WinMTR results. I play WoW on a US server from India ( long story) and I till today I was using my Laptop for gaming which has a builtin wireless adapter and I get around 250 ping ( which is normal for me and perfectly fine.) no lag no delay perfect gameplay. Today I switched to my new PC with a TP-Link TL-WN725N wireless adapter and the game would be fine for anywhere from 5 minutes to 120 minutes but then would absolutely go to !@#$ after that, I could move and talk very normally in chats but none of my skills would go through. This was fine BUT when I tried going back to my old laptop and play, I am getting horrible lag which I haven't gotten in the past 1 year of using the same laptop. I have tried flushing DNS, and all other tips given in forum boards. Is this a wireless adapter problem? Or something else?

Help appreciated,

G'huunspeed all.
Can someone explain why Blizzard would route a PC in north Florida through Europe to connect to Irvine, CA? Is it possible the signal is faster going around the earth?! Maybe there is a glitch in the translation code in Ireland. or between Ireland and France. This disconnection issue is crap to say the least. It's not my modem or ISP. It's your problem to fix Blizzard, so do it already. Please, and thanks :)

I had the same question... here in South America (Chile) Blizzard has a weird route through Netherlands and Miami, FL. Blizzard keep silent and nobody knows what certainly happens!
Is this still a known issue? I run a Hitron CGNM-2250; What's the best way to describe this issue to a ISP tech support personal? I can say it's a manufacturing defect, it causes latency, but besides that... it's really vague and tech support doesn't really understand.
Changing modems is certainly worth a shot. Since wow was fine on my PC til I switched ISP and received one of the listed modems.

Yes it's still an issue, and sadly there's nothing you can do about it. The very best you might be able to do is describe the issue as seen in the DSLReports.com thread linked in this thread and/or badmodems.com and try (probably futilely to get one of the Puma 7 Hitrons instead of the Puma 6 version you have now. You're SOL otherwise since Hitron markets have only Hitron to choose from (I'm guessing you're in Canada on either Bell, Rogers, or TekSavvy).
