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 [0280]: 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.

There is a bug in the current version of bcmwl-kernel-source module available in the ubuntu repository. Have a look @ https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1157880

I installed the patched module available @ https://launchpad.net/ubuntu/+source/bcmwl/6.30.223.30+bdcom-0ubuntu3/+build/4761504 (as specified in that bug) and I got my wireless working with 3.10.2 kernel version :)

    hprem@hprem-mac:~$ sudo dpkg -i Downloads/bcmwl-kernel-source_6.30.223.30+bdcom-0ubuntu3_amd64.deb

  • Please avoid posting the same answer in more than one place. When tempted to do so, typically: (1) the answer should be customized to account for what is different about the different questions, (2) one question should be flagged for closure as a duplicate of another question (you can flag posts with 15 reputation), (3) the answer should really be a comment, or (4) the answer should be posted in the most appropriate place, and one-line comments posted on the other questions summarizing and linking to it. – Eliah Kagan Jul 25 '13 at 04:24

Try installing bcmwl kernel source from launchpad. You need to install the package for saucy and wireless works again. Its kind of upgrade for the default bcmwl driver in ubuntu. https://launchpad.net/ubuntu/+source/bcmwl

download and install the one for saucy and it will work.
