This requires basic registry skills. Simply go into the parameters of your Tcpip files and add the dword “TcpAckFrequency” with the switch flicked to on.

STEP BY STEP

Step 1: Open your runbox and type “regedit” to open your registry editor.

Step 2: Follow this path…
HKEY_LOCAL_MACHINE/
SYSTEM/
CurrentControlSet/
Services/
Tcpip/Parameters/
Interfaces

Step 3: When you get to that point you should find many string entries, look for the one with the most keys (It should have a bunch starting with DHCP and IP).

Step 4: Right-click on that file and press “NEW” then “DWORD Value”.

Step 5: Name the new DWORD “TcpAckFrequency”.

Step 6: Right click on “TcpAckFrequency” and press “Modify”. When the editor opens, change the “Value Data” from 0 to 1.

If you’ve done it correctly, you should notice a drop in ping (ms).
