thnx very much

I had the same problem on a Toshiba Satellite C870-15X with an identical wireless card. The link suggested by actionparsnip also worked for me.

Some people reported that the wireless connection was shaky, but I haven't observed that so far. I will update if I encounter problems with this driver.
