I get wireless when booting the older version, 3.8.0, but no sound, so I'm choosing to fix wireless on 3.9.0 as it seems easier. I am on Ubuntu 13.04. Here's my wireless adapter:
lspci -vvnn | grep 14e4 07:00.0 Network controller : Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)
I tried re-installing using this https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx but no luck
Any help would be immensely appreciated.
