Comment 65 for bug 710738

@vasdi, that looks like a different problem. You can confirm by running 'rfkill list' and verifying that there are no hard or soft blocks on your wlan device.

@m1k0: It looks like you are affected by this bug, but a fix is already applied to be released in the next kernel update, which I expect to be available in about 2 weeks. The kernel is already available in the proposed archive if you wish to test. Instructions for enabling the proposed archive are located at:

  https://wiki.ubuntu.com/Testing/EnableProposed

If you wish to update only the kernel, select only the linux-image and linux-headers package updates after enabling the proposed archive, then disable the archive after updating.
