Well, turning off switching to half duplex worked for me on my win 7 machine with Nvidia eth. adapter.

I was having speed issues with transferring files from my laptop to my two desktops. The two desktops would transfer at a good speed (70-90mbps), but the laptop would only transfer at around 8-9mbps. The laptop has a 10/100 interface and the desktops both have 10/100/1000 interfaces and all are connected by a 10/100/1000 switch. (Yes, the desktops could be faster, but I have not gotten around to upgrading to Cat-5e or Cat-6).
Anyway, after trying tons of things on the laptop as I assumed it was the problem since the desktops could transfer ok, it turned out that the problem was that the flow control was turned off by default on both of the desktop PCs. This caused problems with negotiating the change in speed from 1000 to 100 and therefore slowed the connection down. Turned on flow control on the desktops and *boom* 80mbps transfers to the laptop…YEAH!!!

as i posted before, not sure if it will work on any adapter, but it did increase my tansfer speeds from 200kbs to between 50 and 70mb/s! this is what i did…

go to nvidia’s website and download the latest nforce drivers, then go to control panel and uninstall the “nvidia network access manager” then when your asked ro reboot say no. then unistall all the nvidia drivers, including the display driver (thats just to make sure you uninstall all the nforce drivers, hope you have display drivers on your HDD or download the newest). ok then reboot when asked, but before your pc boots up go into the bios by pressing the del key, only if you have 2 network ports and disable the 2nd one there, just look around, you will find it. now save and exit the bios and when windows boots up and ready install the new drivers BUT WHEN INSTALLING THE NFORCE DRIVERS SAY NO WHEN ASKED IF YOU WANT TO INSTALL NETWORK ACCESS MANAGER…..NETWORK ACCESS MANAGER IS BAD!!!!! NO NAM!!!! K?????. great, restart the machine after everything is installed and when windows boots up again, go to control panel-windows firewall-(on the right pane) Allow a program through windows firewall(even if your not using it or have another installed you must do this step)-then click on advanced on the top right hand tab-then uncheck the box next to the network adapter your using, click apply and close. ok your LAN transfer speeds shoud increase alot now. but if your using bitdefender like im, youl have to do some changes in the frewall settings there, im using 2009 and cant remember if you have to do this in 2008. switch to advance view and on the right choose firewall, now click on network(the adapter name shoud show there if your connected to a network), make sure the trust level is trust all or trust local or something like that, generic is on and stealth is off. close bitdefender and restart your PC. JUST REMEMBER NO NETWORK ACCESS MANAGER AND IF YOU DONT SWITCH OF THE STEALTH ON THE ADAPTER CONNECTED TO A NETWORK THAT YOU WONT BE ABLE TO SHARE ANYTHING……

after i did what i just said my transfer rates went from 200kb’s to over 50-70mb/s. for a small improvement on speed’s you can just disable flow control on your adapter but if your lucky you will get speeds of around 5-10mb/s.

hope this helped!!!!
