Ubuntu 13.04 does not recognize wireless adapter (14e4:4365)

I replaced Windows 8 on my laptop with Ubuntu and neglected to check if my wifi adapter (14e4:4365) would work. I've tried a few solutions to make it work, but I can't seem to make it happen. I don't have access to internet on the computer-I'm at a hotel on a business trip-but I can transfer files from a laptop with internet to the one with the issue.

Result running lspci -nn | grep 0280:

With a temporary wired ethernet connection, please open a terminal and do:

sudo apt-get install bcmwl-kernel-source

Detach the ethernet. After a reboot, your wireless should be working.
