When Windows Vista and the Windows 7 Beta 1 were installed on this laptop I was able to transfer at gigabit speeds with Jumbo frames turned on to the 9KB/9014 range. The issue originally occurred after I had installed the Windows 7 RC. I am currently experiencing an issue on my freshly installed Windows 7 laptop. Server: CC, Host: Naru (Naru sends to CC) 0.0-10.0 sec 21.1 MBytes 17.6 Mbits/secįor comparison here are the iperf numbers between the HTPC and the server Server: Naru, Host: CC (CC sends to Naru) Iperf from the server sending to the laptop (download) > iperf -c miyukiĬlient connecting to miyuki, TCP port 5001 Iperf from the laptop sending to the server (upload) > iperf -c naru I have run iperf with some surprising results: I took my laptop over to my brothers house and was able to copy files at 10 - 12 MB/s over his 100Mbit network so I don't think it's the hardware.
I've completely uninstalled my anti virus software (I am using Avast!) thinking its network filter driver may be causing a problem, that hasn't helped either. I've tried installing the included firewall software (thinking maybe it is interfering - it's not).
I downloaded the latest Vista 圆4 drivers for the nForce 520 (NVIDIA doesn't have any drivers for that chipset for Win 7 yet). I've identified the chipset in the laptop as the NVIDIA nForce 520. As I have it right now I have a cable modem plugged directly into her computer.Ok, I've tried the answers below and nothing has changed. Is there a way to reset the ethernet controller to confirm that is the problem? I've tried to uninstall the controller and restarting the computer so the system detects the new hardware and installs it on its own but the issue remains.
I've tried to find the drivers on Nvidia's website and I download what I think are the right drivers and the problem remains. The only problem is she cannot find the disc.
I called Windows tech support and they tell me my network controller is corrupted and I have to use the initial windows install disc to reinstall all the drivers back to the factory settings.
I tried every simple fix I could think of with no success. So the internet on my girlfriend's computer just stopped working.
