Hi,

 

I have been playing Path of Exile and I have noticed lag spikes and even disconnects from their server.  I have run WinMtr and see that I have some long ping times but I am told they seem to be between my router and PC.  See WinMTR log below. In this case the host is the POE servers I connect to.

How do I go about troubleshooting and resolving this so as to minimize the lag spikes? It happens when I am home alone as well as when there is other traffic on the network. 

 

What info do you need to give suggestions?  I have the Uverse router supplied by AT&T.  Plus an older Netgear unit that is not in use at this time.

Win 7 machine.  Specs below:

Post a Trace Route to that server, either from your router if it gives that option, or through your Operating system.

 

I am showing that ae-2-52.edge4.Chicago3.Level3.net & te2-5.bbr01.eq01.chi01.networklayer.com are the bad hops.  The problem is not on your end, it is those two hops that I posted, that are the problem.

 

Doing a search, it appears this issue with the lag has been going on for sometime.  It is not something that popped up overnight.  Also appears that whoever administrates the equipment for those hops, has not done or care to do anything to fix it.  If you do a search using "bad hop at te2-5.bbr01.eq01.chi01.networklayer.com".  You will get all kinds of results of complaints.

 

This is what my Trace Route shows, just for your comparison:

Hi,

 

Here are three tracerts over the course of about 5 minutes. At 6:45 PM Central time.  I can do at other times if you think it may help.

Looks to me that either they have fixed the problem, or they just had a lot of traffic load on that switch or router at hop 9. It could be that they were getting a DDOS attack at that hop for awhile.

I would just monitor it and see if the problem pops up again.

Lots of lag and disconnects from the game last night.  It was so bad I quit out of frustration.  Perhaps I should contact AT&T, show them the WinMTR klog and see if they can help.

 

The support at the game forums tell me that it is the first hop that is lagging.  I am willing to try to fix anything within my own network.  I will get a new USB wireless adapter and see if that helps.  My current is internal to my laptop. Plus I have my old Netgear router I used before I went to Uverse. I hear there is a way to hook both the Uverse and my own router together.  Any advice on how to do this or a site I can read?  I am doing my own research too and will post anything I find.

 

I will run WinMTR this morning to see if there are different results and post after a while.

Thanks

Have you tried it wired to the 2Wire? And I agree with the game forum that first hop is WAY too slow. 1100's to there is bad. 

 

Besides that first hop, your's and mine look a lot alike. I am on Uverse but on the east coast.


Hope this helps thumbup.gif
