Constant 5 second duration lag spikes and linkdeath while gaming.

Okay, my problem is as such... I'm up visiting my girlfriend's folks in Texas. The both of us are hopeless addicts of MMORPGs, and we picked up a copy of EQ2 two weeks prior to coming down - unfortunately, we've had to jump through hoops to get it to work right down here.

Not a software or hardware issue - we're being crippled by network lag. They're using Centex DSL, a Linksys router, Windows XP, and toggling Norton Antivirus / Norton Internet Security on / off has yielded no positive results.

I'm a novice when it comes to networking, but the symptoms are the game runs smoothly for about 15 seconds. Then a lag spike hits for about 5 seconds. The frequency of these hefty and 'group-killing' lag spikes seems to be random. Anywhere from 7 seconds later to a minute later, but the fact that they happen with such frequency is enough to make progressing in the game an impossibility.

When I ping the server in question (Antoniabayle.everquest2.com) I get ~100ms in response.

However, when I attempt to tracert it, I hit the subnet mask (10.20.32.1) with about 70ms and then get no redirects after that.

Any assistance that could be provided with diagnosing and / or fixing this hassle of a problem would be appreciated! My entertainment over the next 2 weeks ride on you!

Try adjusting the MTU for the connection to the server.  I have written a page on this on my site:

www.doverproductions.com (look under DSL for the link)...  or just go directly here:

http://65.24.134.81/KipSolutions/MTU/MTU.htm

It explains what it is, and how to determine your correct MTU size for your network connections.  When you find the correct size, adjust it on all network interfaces (computer and routers) on your network.

You may also want to look at the Default Send/Receive Window size also, and the link is in the same category.

BTW:  you might want to read through some of the other articles also..  Specifically anything to do with performance.  

Happy gaming!!

Well, this had mixed results; now my performance is better when it's not lag spiking, but it did not solve the issue of lag spikes. *Laugh*

The lagspikes remain the main problem, though. Any other thoughts?

It could even be the the game server is not a dedicated server..  Have you tried other servers?

Oh, believe me, it's not the server, nor the game. This worked fine at home. But to answer yor question, yes, I have tried other servers to the same end.

In that case, I would hold suspect the router (that your tracert command shows dropping packets) is to blame for this lag.  Now that you have adjusted the MTU, try the command again and see if the results are any different.

No different at all. What now?

Did you use the game server's IP address as the target in the Ping/MTU setting above?  If so, then at this point, you may not have anymore options.  If the reason for this lag is the router itself, it is beyond your abilty to solve this.  It could be that the packets are getting bottlenecked somewhere along the path, and that your specific connection does not have the bandwidth to handle them.  This is typical of some flavors of DSL, especially the low bandwidth versions.  It could even be that the problem is with the CO (Central Office) where Centex has its equipment placed, and where the connection becomes 'shared'.

I see. Any other opinions? Just wanting to be sure I've explored all options before I submit to the 'smothering blanket of lag'. ^^

Hm. Mild update, dunno if it makes much difference. But when running the World of Warcraft patcher, it claimed I was 'behind a firewall'. Looking more and more likely the router is to blame. Router up here is Linksys HPRO200

Curious, since this router provides HPNA support.  You are using the Cat5 jacks for your connection, are you not?  Phone line networking is great, but will not give you the throughput that Cat5 will.

I suspected that this might be the case, but no, their network is configured through Phone Line networking - no Cat-5s.

Then, I also suspect that this is the problem.  Although HPNA does give good throughput, it is more than likely the lines themselves that are the problem....  :(
