The internet site sees only the TCP window size of the gateway which
is your router. So simply changing the window size on eCS is not
enough because the router still uses the previous window size.

Looks like the transfer of the settings of TCP are part of the
DHCP protocol or the lan interface configuration. So the router
will only get the new settings when you either renew the DHCP
session or reconfigure the lan interface after changing the window
size.

Did you try to set the window size in TCPEXIT.CMD (or TCPINIT.CMD)
in x:\tcpip\bin before the lan interface gets configured ?
(Don't remember the name of the script as I currently have no access
to my eCS box. Simply grep for ifconfig in all .cmd. In this script
several other scripts are called, either before ifconfig or after.
Take the one before ifconfig and add the required inetcfg stuff.)

When you added the necessary inetcfg calls, reboot!

There is also a way to restart the TCP/IP configuration without
reboot, but I can't remember currently how the script is called.

See above.

From your description of how you got the higher speed, it seems that
your router box has to be reconfigured to recognize the higher
parameters that have in your eCS box. Heiko hit the nail with his
suggestion that you reboot the gateway after you bring up the eCS box.
You can set up a telenet script to do this and call it from your
B4TCP.CMD file (assumes that the gateway has a telenet connection) after
you've set (load) the higher parameters in the B4TCP.CMD file.
Otherwise you would need to hit the reset button on the router (a pain
in rear) each time you bring up the eCS box.

I would write a complaint to the makers of the router box and suggest
that they fix the firmware. I wonder if there is another way to do this....

There has been reports of using eCS at a higher speed without raising
the size of either the send or rec windows. I seem to do that here on
the LAN, which is only running at 100 Mb/sec. Have you tried enabling
selective ACK (sack)?

Actually, yes-- that was one of the recommendations on the tweak site.
I'm sure it helped a little, but the tweak site acknowledged that I had
sack turned on when I get only 4 MB speed.

Next time I have a slow speed problem I'll play with the router some
more. Meanwhile I'll enjoy the better speed.
