Below are Intel's specs. If you ordered your T520 with the Ultimate N 6300 card your are ready. I'm using it with the Belkin Screencast box and it's perfect. One piece of advice: The Lenovo supplied drivers do not work as well as Intel's. Go to
http://www.intel.com/p/en_US/support/de ... lds_detect and have the page autodetect your driver package. Once the Intel Widi applet is installed it will automatically inform you of software and firmware updates. Do this before you plug the Screencast in.
