Diablo 3 causing Modem Reset

Technical Support
Diablo 3 is causing my cable modem to reset. I can browse, play MMO's, use my wifi on my iphone with it never resetting. Anywhere between 5-30 minutes of playing Diablo 3, my modem resets. I don't know what the problem is. Could it be overheating? It sits on my desk in front of a running fan. I would think MMO's tax it just as much if not a hell of a lot more. I have a Motorola Surfboard SB6121. Any help would be appreciated?

lol. i have the SB6120 :D its a little older but its been running good.

anyway, you will need to provide a tracert and pathping from when you are playing D3. then post the info here.

Thanks... I will do that. When searching for an answer, I noticed several other people have the exact same problem that I do. Next time I play, I will run those 2 things. Although yesterday I did upgrade my cable internet speed from 3 Mbps to 50 Mbps download speeds and from 768 Kbps to 6 Mbps upload speeds. Did not get a chance to play last night. So maybe my problem will go away because of that.
Ok, I now have a brand new modem. Motorola Surfboard Extreme SB6141. I have also upgraded to 50 Mbps download and 6 Mbps upload cable internet. Problem still happens. Here is my tracert and pathping.

Problem is fixed, hasn't happened since I updated the Duplex and Checksum Offload in my network card. This is only a problem with Diablo 3. No MMO I have played seemed to mind what the settings were for those two things.

good information to know.
Update... this weekend, the game disconnected 4 times in an hour and I just got frustrated and stopped playing. I did some more digging on the subject and will try disabling IPV6 to see if that helps. I still find it ridiculous that I am having to do all this for freaking Diablo which should be a very light network traffic game. I've played multiple different MMO's and never had any connection issues.

have you tried reseting the modem lately?
you can usually go type in 192.168.100.1 in your browser to see the modem information screen. to reset it you go to "configuration". then just "reset defaults" and "restart cable modem". it may take it a few minutes to boot back up since it has to pull down configuration info from the cable company after you do this. my modem takes around 2-3min, but the config page on mine says it can be between 5-30min.

you can also look at your modem signals to see if everything is fine. really the most important thing to look at on the signal page imo is the power level, as long as it is +/- 12dbmv then everything is usually fine. though i have heard that +/- 15dbmv for some companies and modems is acceptable too so you may just need to see what your ISP says.

Just unplugged modem and router and plugged them back in. I'll try what you said. As far as what my ISP says, they told me to get a new modem. So I went and bought a new modem, same problem.
I reset the modem as stated above. Didn't get disconnected from an hour of play, but died several times to horrible lag. Not much I can do when I am attacking a mob, swing my weapon 10 times and no health drops on the mob, then boom I'm dead when the game catches up. Paused the game, I went out to speedtest.net and was getting 55Mbps download and 12Mbps upload. I can't belive a game as connection light as Diablo 3 is having this much lag and/or connection issues.

speedtest only tests the speed of your connection though. it doesnt test the qualtity of it or the connections in between you and blizzard.

all i can suggest is that if you are lagging do what was stated above with the tracert and pathping. make sure to do it while you are lagging.

i can offer some alternate ways of doing it if needed.

here i posted a trace/pathping file on pastebin. just enter the IP or website you want and it traces and pathpings it for you so you dont have to type them out. it will open the notepad files for you also after its done so you can look at them.
http://pastebin.com/1JqpQtqs
just paste the info into a notepad and save it as type: "all files" name: "trace.bat"

or

you can do a continuous trace with D3TR.
http://www.d3tr.de/download.html
run it for 1-2min and the paste the graph and list tabs here.

How can I do a tracert or pathping while lagging? I only lag big time or disconnect when I am moving around in the game. Usually it's when there is a lot of moving graphics.

*Edit* - Nevermind I read the rest of your post, I was too hasty in replying. I will try the continuous trace thing you mentioned.

Not sure how to paste the graph. I see no way to paste an image. Also, what do you mean list tabs? Need step by step instructions on what you need. I did receive a lag spike while tracing and the graph went up to 2300. Also pasting this from the tool, maybe this is what you are wanting.

this is a quote from another post of mine. you can see the trace graph and the list. the easiest way to post them is just hit "PrtScr" and paste the image into paint. then save it and upload to a free image host.

download the program here: http://www.d3tr.de/download.html
put the IP you want to trace in.
D3 addresses:
The Americas
12.129.209.68
Europe
213.155.155.233
Korea and Taiwan
182.162.134.1

after the trace post your screenshots of the graph and list tabs.
they will look similar to these:
