Slow Network – Windows Vista or Windows 7

Estimated time to transfer files 6hrs …. yep 6hrs and I think it might just take that long…

OK, this can’t be right.  I installed Vista at home on a 2GHZ 768mb RAM computer and it is great!  Now at work, I have a dual core 4GHZ 2Gb RAM PC and copying files and networking is horribly slow.

Here’s a couple of solutions…to help you.  Try one thing at a time and reboot after netsh

Vista’s and 7’s  issues with slow browsing and network operations can be the new TCP Receive Window Auto-Tuning Level – You must run the cmd command as the administrator.

To turn off AutoTuning –  Go to a command prompt (run cmd)
netsh interface tcp set global autotuninglevel=off or use
netsh interface tcp set global autotuninglevel=disabled

Remote Differential Compression (RDC) allows applications to synchronize data between two computers.   Turn it off….Start >> Control Panel >> Programs and Features
Click on ” Turn windows features on or off” on the left side of the panel
Takes a sec to load all the features
Uncheck “Remote Differential Compression”

Make sure you’ve got the latest drivers for ALL your hardware components.

Adjust your network card under the Device Manager-

Right click on your network card and go to properties
Select the Advanced tab
Select the Link Speed/Duplex Mode property.
Try Auto Negotiation.
Try 100Mbps/Full Duplex or 100Mbps/Half duplex
It is safe to try these alternative settings to see which setting works best for your PC’s Network card.

On last thing for performance
Go into Device Manager, open the properties windows for your HDD, select policies, check the box that says “enable advanced performance”.

Cross your fingers…
