Hi I have Comcast internet and I get 120mb download and 12 upload on the computer I use. For whatever reason my girlfriends computer gets 120mb download but only 1mb upload the highest I've ever seen is 2mb upload on her computer. The computer is wired to the router not wireless. It uses a Marvell Yukon 88e8056 network card. It's using a P6T Deluxe V2 motherboard. Any help is appreciated I've looked at many threads and can't seem to find the issue.

Also this seemed to have only happened within the past few months. The upload on the computer was fine until around the time we got a new Modem from comcast. It may be a coincidence but not sure if that could do it.

Also the modem is a Comcast supplied Arris TC862.
