This is my first post. So forgive me if I'm not giving all the details.

My OS:- Ubuntu 13.04

My problem is, After upgrading to kernel 3.9.3(from kernel.org), I'm not able to access my wireless network. The wireless button in my laptop indicates that it's ON, but it is not being detected. I have gone through all the posts and have tried all the stuffs, but no results.

This is the output of lshw -C network network

 -network UNCLAIMED

The following is the output of lspci|grep Network command

The following is the output of rfkill list command
