    Unhappy Time Warner Upload Speeds

    Ok, here's the deal. I work from home and I have the turbo package from Time Warner Cable. I don't remember my download speeds but for upload speeds I am suppose to be getting 512kbps. That's what I pay for. The problem is I am not getting that and my job requires that I hit that mark or a 2% variance (490kbps) in order to keep my job. Currently, I am getting 489kbps. Does anyone know of a tweak that can increase my upload speeds by 1 point? That's well within the legal limits of what I am suppose to be getting in the first place. I have already tried the TCPOptimizer Tool and unless I'm missing something that tool did NOTHING to increase my upload speeds. PERIOD. I have tried disconnecting my other devices from my internet connection and that didn't work. I have tried defraging and clearing my cookies and cache and that didn't work. Are there any other suggestions that one might know of? Thanks for your help.

    Is there possibly a setting in the TCPOptimizer tool that I am overlooking? If someone tells me which setting I need to tweak in order to obtain this goal then that would give me extra guidance. Thanks for the help.

    Upload speed cannot be tweaked under TCP settings. You can try the tweak to AFD parameter in your XP.

    Download and run Cablenut and enter just one field:

    DefaultSendWindow - 65536

    Thanks, Trogers and Osully, for responding to my OP. I tried both of your suggestions. DSL services have a significant decrease in download speeds while showing a gain in upload speeds so that's a new obstacle I have to face, and I downloaded and installed the program and then followed your instructions, Trogers. My upload speeds did not change. Can someone tell me how to uncap an smc modem or show me how to tweak my cable modem settings simply to pass this test? That would be helpful.
