Found a way to 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.
It took me a while to figure out how to do this since I'm not computer savvy. But I did figure it out, so here is the way I did it.
Click Start
Click Control Panel
Click Network and Internet Connection
Towards the bottom again Network and Internet Connection
Double click on Local Area Connection (new window will open)
Click on Properties (New Window will open)
Click on Configure (new window will open)
Click on Advance
Click on Speed & Duplex (yours may not say it like mine so find the title that deals with speed)
To the right it has a Value box it will say Auto Negotiate. Change the Value to 100 full duplex or 100 full mode.
I checked this mode using bandwidthplace.com so with BellSouth DSL 3.0 before mode results

Now the weather here is very poor (TS Barry) so I know both of these test are off. But the was still a good improvement over the standard connection. I found this mode on TweakXP.com http://www.tweakxp.com/article37130.aspx Enjoy faster browsing.....Oh and if there are any computer savvy folks here who see a problem with the mode please speak up. I've had the mode since last night and have been very happy thus far.
 
Full duplex allows your computer to send and receive data at the same time, where half duplex only allows one way communication. Using full duplex will increase network performance, possibly even web browsing, but it should have no effect on an internet bandwidth test. For one thing, most of those tests do the upload and download separately so duplex should not matter. Second, your internet connection is at 3.0mb and your local network connection is 100mb...Which means your network should not slow down the internet connection at all.
 
So why does it affect the test scores? I've reset it a few times and each time they increase after changing it to 100 full. I'm always facinated with tweaks I just wish I was a more computer savvy. Is there any way of increasing internet speed by tweaking things around? 6.0 is still not available heer so if I can sqeeze or uncork some more speed that would be great.
 
Low5-0 is spot on. That should not have any effect on your d/l speeds to the internet, the only area it would affect is if your doing huge file transfers over your LAN.
BTW, I <3 15Mb FiOS!

Communications 11 megabits per second

Subjective rating Unbelievable

Also, check out speedtest.net, it's a real sweet GUI bandwidth test.
