Slow Upload speeds

I'm having trouble with slow upload speeds on my vista ultimate x64 machine. My ISP is providing a 25/25 connection and the download is working fine but the upload is only at ~1mb. My router is provided by my ISP(Verizon) and just has their name on it with a model number of MI424WR on it. I have other computers running XP on the network that can upload/download just fine and if i plug the ethernet cable thats in my vista machine into my laptop that's running XP it can upload/dowload just fine. The slow upload occurs when trying to transfer files over the network as well as when online. I had Avg anti-virus installed but have since uninstalled it and have not seen any change in the upload speed. I also tried turning off Remote Differential Compression but it seemed to have no effect on the upload speed.

My system specs are as follows:

ASUS P5N-T Deluxe NVIDIA nForce 780i SLI Core 2 Quad Socket 775 1333MHz PC2-8500 (DDR2-1066) ATX Motherboard
INTEL Core 2 Extreme QX9650 3.00 GHz 1333 MHz Socket 775 12MB
BFG GeForce 9800 GX2 1GB PCI Express 2.0 Video Card
WESTERN DIGITAL VelociRaptor 300GB SATA II 10,000 RPM 16MB Buffer Hard Drive
PATRIOT 4GB PC2-8500 (DDR2-1066) DDR2 Memory

Any help or comments are appreciated Thank you

It could be a driver setting, check the device manager for the ethernet adapter's settings and check that everything is correct. I know some cards default to full 10/100 duplex, maybe something went wrong was accidentally changed.


Hope this helps. If not post back
