Firstly, I play World of Warcraft, and I have internet issues at peak times.


Basically, I raid at 9pm-2am, however, as soon as peak times come up, I start disconnecting whenever I enter a raid, and I also have random spike lag when in the world.


Is there anything I can do to fix this? Or should I just give up on the idea of raiding?


Customer Support has been largely unhelpful in this regard.

Have a read through the other xnet threads, int speeds have been an issue for a long time.

Thats the thing, speeds are not an issue. I can download at 150-300kb/s easily, while I have this connection issues.


Or are there some other kinds of difference?


If so, what are my options? Would I have to change ISPs? And if I do, what would be some good suggestions for Dunedin?

What about upload speeds. What sort of speeds are you getting to the wow server?

hmm, I haven't checked upload speeds actually. However, since the only place issues occur are in raids, where there is a large amount of incoming traffic, but outgoing remains the same, I am not sure how much this actually relates to it, though I could be wrong, as I know little about it.


What do you mean by what sort of speeds am I getting? I hold a very stable ping of around 250 normally, but it randomly spikes at peak times.

It's sad to hear they are still having problems with international gaming in peak time as it was one of the reasons I changed away from Xnet back at the start of 2008.

I haven't played wow in ages but when I used to play I had no problems on Telstra PDQ.  I know wow players using Telecom, Telstra and Snap who don't have any major problems.  Occasionally I still hear about Orcon and Vodafone peak time international gaming and US ventrillo server problems so I would avoid them.

If you are not using a ssh tunnel service like www.wowtunnels.com or www.pingbetter.co.nz I highly recommend giving one a go.  The interaction between delayed tcp acknowledgements and the nagle alogorithm causes double latancy for oceanic players on US severs.  If you get 400-500ms currently you can cut that down to 200-350ms by tunneling your wow traffic over ssh with an endpoint in the US near to the wow server data center in LA.

It's not just your ISP

I have reports of it happening to 2 isp's in australia as well as people on Orcon (like me)

Seems to be losing packets in AT & T 's network.

Not really any fault of one particular ISP or Blizzard.

After Blizzard don't provide networking services - they rely on a third party provider for that.

I've had it happen from aroun 12.30 = 1.30 then it correct itself. It'll be fine for aroun 45 - 50 mins that it would go laggy again then be fine again.

Normally I get 300 ish to Muradin. I've seen it go to 700 then to 1440 then to 2758 then to 4000 then back down again.

If you have a look at that thread I posted it's happening to wow players in Australia as well as malaysia. The traceroutes they have posted are starting to look very similar.

Oh and I've never had a problem with my peak time international gaming with Orcon. The odd "lol lag" issue but never as bad as this. I run up to a mob , press buttons and nothing happens. Nothing at all. It then all happens at once. I'm used to getting 300ish latency on Muradin. it's been spiking as high as 4000 or 8000 on me /wrists

If you are not using a ssh tunnel service like www.wowtunnels.com or www.pingbetter.co.nz I highly recommend giving one a go.  The interaction between delayed tcp acknowledgements and the nagle alogorithm causes double latancy for oceanic players on US severs.  If you get 400-500ms currently you can cut that down to 200-350ms by tunneling your wow traffic over ssh with an endpoint in the US near to the wow server data center in LA.


Well nice but I thought they fixed that in patch a bit ago when they disabled the nagle algorithm . And as I understood it you could recreate the affect both of those tunneling services were having by having a couple of linux servers setup in a special proxy for your wow connection. It's been a while but I could possibly dig up the link for you to have a look at.

Then again an SSH tunnel service might not help much if it's an unusaully high lag - a few hundred MS off isn't going to make much difference when it's spiking as high as 1440 - 8000 ms

Has anyone thought about changing MTU sizes to see if it makes a difference? Maybe using something smaller than the default 1500. Anyone with more experience could give an input?

The nagle alogorithm is disabled in the client side but not on the server side, the client side was diabled way back during TBC it had a positive effect but didn't 100% solve the problem.  I doubt they will ever turn off the server part for a number of reasons.  A few people did some thorough traffic analysis that was posted on the ElitistJerks forums back at the time.

So you can still signifcantly reduce your ping with a decent SSH tunnel still, you can also bypass the problematic AT&T routers if your route to the SSH endpoint is different to your route to the wow servers.

Ok you might reduce your ping with a decent SSH tunnel I'll give you that.  

But will it help with the huge lag spikes I've been getting.

I usaully get around 280-334 latency on Muradin.

The spikes only last aroun 30 - 50 mins each time. Once the laggy time is over my latency goes back down to normal.

Do a tracert to your wow server and compare it to a tracert to a few of the wowtunnels ssh servers (eg:  tunnel5.wowtunnels.com and tunnel2.wowtunnels.com) and compare the route taken see if you bypass the problematic AT&T router.
