Yao and Linux

As the "clean room" policy proposed by my wife, I bought a USB wireless card for my machine, and cost me nearly 4 days to set it up under Ubuntu.

After a long time googling, this post helps me a lot...

After followed steps in this post above, it still doesn't work. Then, I upgrade my ubuntu 9.04 o 9.10. Everything works well.
