3. Connection and Tweaking
To change your MTU to 1400, download DrTCP to your desktop from here.
Set your Dial-up Adapters MTU to 1438 from the Adapter Settings list. If you use ICS, then you will also need your MTU to 1438 under ICS MTU. If you also use a NIC, then set that to 1438 under Adapter Settings as well.
Click Save, Exit and reboot your PC. Run a tweaks test to confirm that your MTU is now 1400.
The reason behind the 1438 MTU value is that there is an awkward 38 byte overhead, which is deducted from the actual value your entered on your dial-up adapters.
In other words, 1438-38 = 1400 - Your actual MTU result.
By default, MTU is set to 1400 bytes upon installation of the client.
Reserving 0% bandwidth for QoS-aware programs in Windows XP Pro can boost your broadband speed by 20%. Results will vary and may not work at all for some people. The tweak can be found at TweakXP.com.
My general rule would be that if your speeds are over 80% of your cap, then this isn't affecting you. If you are getting below 80% of your cap, it may help you.
A symmetrical connection (where the downstream and upstream are the same speed) is ideal for business use. If one person on the network on an asymmetrical connection uploads a large file, then everyone will slow down.
Find a fast FTP server that can support alot of bandwidth. We'll use OOL's FTP as a fine example. Download this file to your desktop or run it from it's current location.
When it gets to about 20%-40% done, take a note of the KB/s and cancel the download.
Multiply the KB/s you got by 8.192 to determine your speed in kbps.
Example: 92.4KB/s * 8.192 = 756kbps.
If your speed appears still to be slow, then it is time to contact your ISP.
List of FTP Sites:
Note: Depending on your geographical distance from the FTP server, speeds will vary between closer DSLR/Speakeasy.net tests and your result from this method.
If you have anymore fast FTP servers with big files for testing, then message me through DSLR's instant messaging system with the URL. Must be in the U.S.A.
BroadBand Tweaks forum and include the 11 questions on the pre-post page so the helpers there can help you squeeze every kilobyte out of your connection. If you wish, you can post in the AOL Plus forum
Additional notes: AOL Plus MTU can only go up to 1454, but using too high of an MTU will cause problems on secure sites, so use a maximum of 1438.
WARNING!! This should be for advanced users only. This may cause serious problems to your dsl modem if the necessary precautions are not taken. Again, only do this if you find out your modem is unable to sync on your line.

The following items are found: VPI and VCI Table.
If you do not know your VPI/VCI contact your local telco. They will tell you; but don't disclose what ISP you use. Otherwise, try these common settings from across the globe:
(List Credit to »steve-parker.org)
So if you're in the US, try using either 0/35 or 8/35. One of those settings will allow your modem to sync on the line.
Scroll down on the VPI or VCI.
Go to the VCI or VPI table and select the correct number.
Click EDIT VCI or EDIT VPI and click "enable" and then OK.
Click apply again.
