Optimize Broadband-Dial Up Connection?
(4 posts)
Things like that are a waste of time and will eventually cause problems to Windows. You won't see them straight away but at some time in the future things will one-by-one start going wrong. I have experience with that software and it's pointless and a hazard to your system. The modem design, your ISP, and prevailing demand on the internet system determine the available bandwidth. Apparently, it's possible to get 20 meg speeds on mobile broadband but you need to find out in your own area if it's available...you need the right dongle, package and location. The upshot is, the solution lies OUTSIDE your computer.

W7 'supposedly' is ALREADY optimized for your connection... and messing with it doesn't usually help. XP, a different story.
However, if you want to 'experiment', LOOK AT THIS WEBSITE PAGE.
Be WARNED, I tried some of the stuff there and I had connection problems. Specifically the ECN Capability setting. An MS tool showed my router was capable, but by changing the setting, my speed DROPPED!!!
Here is what I found and use...
==================
Querying active state...
TCP Global Parameters
----------------------------------------------
Receive-Side Scaling State : enabled
Chimney Offload State : automatic
NetDMA State : enabled
Direct Cache Acess (DCA) : disabled
Receive Window Auto-Tuning Level : normal
Add-On Congestion Control Provider : ctcp
ECN Capability : disabled
RFC 1323 Timestamps : disabled
BAD Settings
Querying active state...
TCP Global Parameters
----------------------------------------------
Receive-Side Scaling State : enabled
Chimney Offload State : automatic
NetDMA State : enabled
Direct Cache Acess (DCA) : enabled
Receive Window Auto-Tuning Level : normal
Add-On Congestion Control Provider : ctcp
ECN Capability : enabled <--- PROBLEM
RFC 1323 Timestamps : disabled
RESET to GOOD....
============
On W7, YMMV....
Here is a small .BAT file that will set the settings :
================
@echo off
echo Setting TCP/IP flags...
echo -----------------------
echo This only succeeds when run as an administrator,
echo when run as a user it only shows the current settings.
echo.
pause
echo.
netsh int tcp set global rss=enabled
netsh int tcp set global chimney=automatic
netsh int tcp set global netdma=enabled
netsh int tcp set global dca=enabled
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global congestionprovider=ctcp
netsh int tcp set global ecncapability=disabled
netsh int tcp set global timestamps=disabled
pause
cls
echo Current settings:
echo -----------------
netsh int tcp show global
pause
=========
This one should RESET it to the default :
===================
@echo off
echo Setting TCP/IP flags...
echo -----------------------
echo This only succeeds when run as an administrator,
echo when run as a user it only shows the current settings.
echo.
pause
echo.
netsh int tcp set global rss=enabled
netsh int tcp set global chimney=automatic
netsh int tcp set global netdma=enabled
netsh int tcp set global dca=disabled
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global congestionprovider=none
netsh int tcp set global ecncapability=disabled
netsh int tcp set global timestamps=disabled
pause
cls
echo Current settings:
echo -----------------
netsh int tcp show global
pause
=====================

You always want to Optimize a DIAL-UP ANALOG MODEM.
Here is Normal Register Configuration in an Analog Modem.
http://michaelgellis.tripod.com/modem.html
To Optimize, have to use AT Command Set to change the Registers in the Dial-UP Modem.
I have books on this stuff but will have to find you an on-line reference something like below.
