I remember someone on here saying how to optimize TCP/IP on WindowsXP for cable internet. It was really helpful because I would get bursts about 3 times as much and higher sustained rates. I think the utility was Dr. TCP but I forgot.

Does anyone know these settings?

Download DrTCP: <a target=new class=ftalternatingbarlinklarge href="http://www.dslre

Run the program, it will show the current settings of TCP/IP parameters. Write them down.

You can change any variable that you want, click Apply, and reboot the computer, if no good; you can always change to your original values.

Start with:

MaxMTU - for DSL =1492 Cable=1500 DialUp=576

Tcp Receive - 255552

Window Scaling - Yes

Time Stamping - No

Selective Acks - Yes

Path MTU Discovery - Yes.

Black Hole - NO

Max Duplicate - 2

TTL - 64
