if you are connected via ethernet...and your local area connection says 100mbps...then right click my computer->properties->hardware->device manager-> click + next to network adapters. Right click your nic. And go to advanced and change the speed and duplex to 10 mbps full duplex....
reason...when your lac is set to 100...it actually cause slower speed. Justlike if you have crappy lines. and you have a 7 meg connection. You may actuall expirience much slower speeds than if you were at 1 meg...
if i didnt explain well enough. let me know...lol
edit:
sorry didnt see your post...but im 99% sure thats what he is talking about
