Speed up network file transfers on 100Mbps networks

This tweak will speed up your network to the speeds you thought you were getting.  It is dependant on the network equipment that you are using, so please see the oppropriate section.

By default windows uses an auto detect feature to determine your link speed.  This feature can not handle 100Mbps.  to change it. Click Start  and right click on "My Network Places" and select properties.  On the network connections windows, right click on the adapter for your network connection and click properties.  Click the configure button on the Local Area Connection Properties window.  Click the advanced tab on the new window. Highlight the one on the list that relates to speed. (My one card is Speed & Duplex, where the other is Connection type, i have also seen media type, and i am sure there are others)  If you can figure out which one it is, simply click each one, and look at the value box, your speed property will have the value Auto Negotiate.  Change this value to one of the following:

Hub Networks

Hubs can only handle half duplex speeds (50mbps in / 50mbps out = 100mbps), because they lack the ability to create virtual circuits as they are stupid, so set this to 100 half duplex (i've also seen 100 half mode)

Switch Network

Switches are smarter devices, and can handle full duplex speeds (100mbps in / 100 mbps out = 200 mbps), because they know which port the destination computer is, and create a virtual circuit to it, so set this to 100 full duplex (i've also seen 100 full mode)

Router Network

Routers, with buit in hub, see hub section, routers with built in switch see switch section.

Please remember to make these changes on every computer on the network, or you will no notice a change.  A transfer is as fast as the slowest connection, in most cases, windows auto negotiate.

To increaase your speed further, refer to

this will remove the 20% cap on your 100 mbps full duplex network

Enjoy the network speed.

Don't listen to Mike.
Do what he said, and you'll end up with duplex mismatch problems and collisions.
Tinkering with duplex settings is one of the easiest ways to bug your connection down in strange ways, while automatic detection just works!
Same for the 20% thing, just as silly as this one.
