Set Tcp Receive Window to 63888

Set Windows Scaling, Time Stamping, Selective Acks, Path MTU Discovery, Black Hole Detection to Default.

Leave Max Duplicate Acks and TTL Blank

Using the drop-down menu in The Doctor set your NIC’s (Ethernet adapter’s) MTU to 1492.

Save/Exit DrTcp

Reboot

Rerun the Tweak Test

Run Two Speed Tests from the two DIFFERENT cities nearest to you that are listed here: Speakeasy POPs

Also, test here »ftp://ftp1.optonline.net/test512

Note your transfer rate after about 30 seconds. Then cancel the download.

Post the URL for the New Tweak Test. For the TWO Speakeasy Tests, Copy and Paste the speed results from those tests and note the speed from the FTP download test.

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.

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:
