11.10 slow wireless on thinkpad t420

Hello,

I am having issues with my wireless connection slowing down after a few minutes of browsing (starts aroud 7 mb/s, drops to 0.3 mb/s). When I disconnect and reconnect to my network, the connection speeds up for a minute or two. The computer is set up to dual boot into windows 7, and the connection in windows is fast. I have tried turning off power management, changing to the google DNS server, and making and installing the driver from realtek. I have also tried swapping out the router with no improvement.

Thanks for your help,
Josh
