This is what I did to slow network. It pertains to the person starting the thread.
Using Linux Netbooks connected to a Linksys E3000 w/ DD-WRT. Transfer speed were a respectable 30-45mbit.
My work laptop w/ Win 7 ultimate was getting on LAN = 768k (LOL?) On same network as Linux laptops
The Fix:
Windows 7 Machine (access through control panel or device manager)
> Network Adapter > Advanced Settings>Power Management Tab> Uncheck allow computer to turn this device off
> Network Adapter > Advanced Settings
In the drop down menu look for and Disable power saving. Depending on the card, there might not be a setting. **** you can google what some of the settings do. On a home network. I wouldn't change to much. IE Enabling 'jumbo frames' might see a LAN speed increase but wreck havoc on high latency apps such as VOIP.
My speeds went up to 12mbit.
I did ton's of troubleshooting. Different routers, Nic Cards, Cabled, WiFi and etc. If you're using primarly WiFi. The power saving change will result in a significant increase of data throughput. Wired networks- change settings to match router/switch port IE 1000 mbit ful duplex or etc.
