Fix The Lag On Windows Vista

[ironman2173]

Hello mmowned, i have recently learned that windows vista users seem to have a latency problem on wow. And here is the fix!

First of all you have to go to X:/Windows/system32/cmd.exe
Then you have to make it a "Elevated Command Prompt". By right-clicking it and pressing "Run As Administrator".

When you have the elevated command prompt loaded up... Type in...
"netsh interface tcp set global autotuninglevel=disabled"
Without quotations. When you type it in....press enter.... then in a few seconds....it should come up under it "Ok".

Load up wow, and then you should be lag free!
Have Fun!

Would love to know the technical explaination as to what this does

I've seen this posted on a private server's forums that i used to play on. I tried it and it actually did improve my latency somewhat. But not significantly.

"netsh interface tcp set global autotuninglevel=disabled"

Receive Window Auto-Tuning is a TCP/IP Setting

Basically what Receive Window Auto-Tuning does is checks to see if the receiver of the packet of data has enough space to store that packet, and if they don't it wont let the sender send it. Turning it off wont hurt anything but you might lose the occasional packet data at which point it just needs to be resubmitted which the program will do for. This really isnt going to increase your speed a lot, it might a little but its not going to be like "OmgWtfBbq My Comp is teh h4x now" Only reason it would increase your speed because your computer wouldn't check to see if the blizzard servers had enough cache space available to store the packets you send them when you do anything on WoW. I don't know exactly what the delay is for the check but it cant be more then a few ms, which is hardly going to be noticeable.
