I've read in this Question that a new package exists for this driver. But I am confused. There are a lot of packages and I don't know which one do I need. I have a DellVostro-3460, Ubuntu 12.10, kernel 3.5.0-17-generic. Thanks for any help.
For 12.10, you need linux-backports-modules-cw-3.6-quantal-generic. You will also need its dependency linux-backports-modules-cw-3.6-3.5.0-17.
