Tweaks?

[Shadows]

Sorry, I'm kind of new here, but I think the following is all the information you need to suggest some tweaks?

OS = Windows XP

I've got DSL and I believe I have a 768k package? Not quite sure, but the information above may contradict that.

Thanks in advance.

Download this program

Enter just one item below and leave all others blank or unchanged:

DefaultReceiveWindow - 31944

Click 'Save to Registry' and exit. Reboot comp and do another TCP Analyzer report.

Apologies for the delay, was away for a few hours. Anyway, here is the analyzer report you requested

TCP Window is now correct at 31944.

[Shadows]

So this is the best the connection will ever get? Excuse my ignorance.

Yes. You are getting 96% of your speed package of 768 kbps.

[Shadows]

Sorry to reopen this dead thread, but I upgraded my internet connection and am looking for a new tweak. Connection now is 3mb/768.

Verizon said it may take up to 24 hours for the speed to reach its maximum, and it has only been a few hours.

Try again the setting that I gave and make sure TCP Window is set to 63888 and Windows scaling uncheck.
