[ubuntu] No wireless after upgrading kernel to 3.9.0

view story

http://ubuntuforums.org – 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: Code: lspci -vvnn | grep 14e4 07:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01) And then Code:   *-network UNCLAIMED            description: Network controller       product: BCM43142 802.11b/g/n       vendor: Broadcom Corporation &n (Hardware)
