WoW spiking to hell!

For some reason I am getting horrible latency spikes while playing world of warcraft. My dbm is good all the time usually in the -70's and whenever I tracert to different IP's/websites I get average 90-160ms pings. But it's just online gaming in general that I have bad pings and horrible spikes.

I've tried everything. One thing I've noticed is that hop's #2 and 5 are timing out on ALL tracerts.. and my PER (packet error rate) in ##DEBUG doesn't stay at 0 consistently. It jumps sometimes to 8 or more.

I'm afraid calling sprint will be a waste of time because standard tracert's are showing reasonable pings.

Does anyone have any advice?

running winxp with a pantech-px500 located in northern florida.

After some research and messing with a few things I've miraculously achieved <300ms 'green' pings while playing WoW (averaging around 250ms) good as it gets with wireless I suppose, and also my extreme 2500+ms spikes have disappeared (aside from the casual realm related lagouts) I'm usually green 90% of the time.. this includes being right in the middle of major cities during prime-time hours. I only had to add 2 things to registry in WinXP;

#1:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\

There will be multiple NIC interfaces listed in there, (they have long names like {7DBA6DCA-FFE8-4002-A28F-4D2B57AE8383}. Click each one, the right one will have your machines IP address listed in there somewhere. Right-click in the right hand pane and add a new DWORD value, name it TcpAckFrequency, then right click the entry and click Modify and assign a value of 1.

You can change it back to 2 (default) at a later stage if it affects your other TCP application performance. it tells windows how many TCP packets to wait before sending ACK. if the value is 1, windows will send ACK every time it receives a TCP package.

#2.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters

Right-click in the right hand pane and add a new DWORD value, name it TCPNoDelay, then right click the entry and click Modify and assign a value of 1.

Click Ok and close the registry editor, then reboot your PC.

---

I must also note that I originally ran TCPOptimizer a few months ago and it deleted and changed several keys on my system which I thought had helped with my speeds.. but I have since reverted completely back to my original registry settings without any tweaks, besides the 2 that I listed above, and my speeds are even better hitting peaks of 1300kbps up and 300+kbps down.

Hope this tweak helps for any other fellow WoW'ers out there. Good luck!

Tried this but the MSMQ section is missing on my pc. I am having similar issues but with Verizon Latency is ok one min the Spikes all to hell. Not sure how to fix it since i cant find the file in the second part of the registry tweak. Getting Very frustrated as my dbm is at 90 - 85 and ping is usually 400-500ms, i can live with that but its spiking alot to 2K+ and sometimes DCing me. Sad

I have been experiencing the exact same thing. My Sprint EVDO RevA connections has been quite good for my WoW game until recently. I can't wait to get home and try this tweak!

Thought I would just chime in here and let you guys know how I got around this problem. I believe it is due to traffic shaping (the process some ISPs go through to prioritize traffic)

Here is the link from begining to solution of my problem.
