No wireless after upgrading kernel to 3.9.0

[sobinary]

My wireless was working fine on kernel 3.8.0, but no longer works in 3.9.0. By that, I mean "Wifi" isn't even an option in the Network Settings.

I'm using Ubuntu 13.04 on a Sony Vaio Fit 14E. Here's my network adapter's info:

 lspci -vvnn | grep 14e4
07:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

And then

  *-network UNCLAIMED            description: Network controller
       product: BCM43142 802.11b/g/n
       vendor: Broadcom Corporation
       physical id: 0
       bus info: pci@0000:07:00.0
       version: 01
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress bus_master cap_list
       configuration: latency=0
       resources: memory:c0700000-c0707fff

I've tried installing different drivers for the 43142 with no success (maybe incorrectly?). Ethernet works perfectly.

Any help would be immensely appreciated because I need this computer for work. Thank you!
