I noticed a lot of questions over this topic, I skimmed over a few of them to see what people are doing to reduce they're latency. One method not mentioned is the TcpAckFrequency trick. I found a video that showed me how to do this but can't seem to find it again. I play WoW I normally have about a 250-300Ms ping on average with an 8Mb connection. I tried it out and it always cut my latency in half to 80-115MS average now. windows xp, vista, and 7 owners can use this trick (only because I'm not familiar with other OS)

Step 1. Open Run and type in "regedit" without the "."

Step 2. Find and open the files in this order: HKEY_LOCAL_MACHINE -->System-->Current Control Set-->Services-->Tcpip-->Parameters-->Interfaces.

Step 3. Now find the file under Interfaces that has YOUR ip address

If you don't know your ip address open your command prompt, you can open RUN and type cmd, or look in your accessories folder. Once the black box is open type in 'ipconfig' the numbers next to Default Gateway is your ip address.

Step 4. once you find the file that has your ip address, right click anywhere and click 'New' then click D-Word value 32bit

Step 5. Name the new file (i usually just put TCPackFrequency not really important just a name).

Step 6. Right click on the file and click Modify set the value data to 1

Step 7. Close the Registry editor, and refresh your ip address, you can do this by going back to the Command prompt and typing ipconfig release hit enter, the default gateway should have no numbers next type ipconfig renew, now the default gateway should have some numbers.

Step 8. YOUR DONE! enjoy less latency and ping times
