Hi davenline19, Welcome to the forums !

Please connect your laptop via cable, then try this solution : http://askubuntu.com/a/215923

If it works but fails to load again on next reboot, do this -

Code:

echo "wl" | sudo tee -a /etc/modules

Post back the result. Thanks.

Re: Broadcom BCM43142

had similar problem with BCM43228 on Ubuntu 13.04 (Raring Ringtail)

in the liveCD installation it worked to simply select the 'software and updates > additional drivers, > Using Broadcom 802.11... STA wireless... driver...'

but after the install this did not work. (also my LAN did not work, so had no network at all),

the way I solved it was by using dpkg and the CDROM source files like this:

cd /media/myusername/Ubuntu 13.04 amd64/pool/main/d/dkms/
dpkg -i dkms_2.2.0.3-1.1ubuntu2_all.deb
cd
cd /media/myusername/Ubuntu 13.04 amd64/pool/restricted/b/bcmwl
dpkg -i bcmwl-kernel-source_6.20.155.1+bdcom-0ubuntu6_amd64.deb

that fixed this for me, next is to fix the LAN.

Take a look this information, from Jasmine's Debian Repository.
