Sorry if my reply come so late.
As I said in my first post, I had exactly the same problem as ozorens.
The problem wasn't from the router or cable (or my OS as I was thinking). I only fixed it by installing another driver for the network adapter. I installed driver 7.46.531.2011 and haven't got a disconnection since that. So I think the problem was from the network adapter driver. I had the problem with both the driver from the CD that came with my laptop, and the driver from the site but no problem with this new driver.
