If you are not too worried about anything other than wow lag.
To get low pings with 2 simple registry hacks do the following. You need to apply both registry changes to get the maximum effect. 1 - TcpAckFrequency - NOTE if you are running Windows Vista this setting may not have any effect - a hotfix is needed which i'm tracking down. This works fine under Windows XP Type "regedit" in windows "run.." dialog to bring up registry menu Then find: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\Interfaces\ There will be multiple NIC interfaces listed in there, find the one you use to connect to the internet, there will be several interfaces listed (they have long names like {7DBA6DCA-FFE8-4002-A28F-4D2B57AE8383}. Click each one, the right one will have lots of settings in it and you will see your machines IP address listed 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 - TCPNoDelay This one is pretty simple Discussed Here Type "regedit" in windows "run.." dialog to bring up registry menu Then find: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Paramet ers 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 have found the performance to be at least as good as routing via a linux box, possibly better. -------------------- retired

the real fix it seems is to plug directly into your modem or change your router MTU setting to 1024 or less.
