Windows 7: poor transfer rate in 100/1000 Mbit LAN ethernet but only 3 MB/s speed

26 Dec 2012   #1

Windows 7 Home Premium 64-bit SP1
poor transfer rate in 100/1000 Mbit LAN ethernet but only 3 MB/s speed


i just got new hardware and switched OS from XP to WIN7 (Home Premium 64 bit).
When i copy data via my ethernet connection (LAN cat 5e cable) the transfer rate is about 3 to 3,5 MB/s

I use MSI Mainboard Z77A-GD55 with Intel network adapter 82579V (onboard), latest drivers installed,
cat 5e ethernet cable, TP-Link Gigabit Switch.

This is what i did so far:
-autotuning disabled
-ipv6 disabled
-Remote Differential Compression disabled
-firewall disabled (antivirus software not installed yet)

but no improvement

what else could i check? where do i have wrong settings? any ideas?
thx for help, i am really lost here
