| [DSL] Problems tweaking
So here is our setup
We got a Watchbox Firebox II running as a firewall and our pppoe authentication. Modem is plugged into it.
We are suppose to be getting 8mbit down and 1mbit up (the bell tech said our modem shows as being synced at 10mbit!).
Here is the problem, both my machine and the exchange server are tweaked with 64240 rwin yet on tweak tests on both here and speedguide.net it shows some other number.

Thats my tests, please let me know what we can do to fix it.
Oh the speeds we are getting are as follows:

This will reset the registry to default TCP/IP values.
Open a Command Prompt and type:
netsh int ip reset c:\resetlog.txt
Reboot. See if The Doctor works now.

| Did you by chance use the SpeedGuide tweaker?
Have you tried connecting directly to the MODEM? |
