enable wireless adapter

[shmish]

Hello,

I have installed Kubuntu 14.04.
I have an internet connection through my ethernet adapter but I'd like to get my wireless working. When I open the internet setting from the taskbar, the wireless icon has a cross through it. Hovering over the icon, I get the message "wireless disabled."

I went to System Settings -> Driver Manager, but this screen is blank with no information about any drivers (I posted a separate thread about this).

The output from lshw is:

sluggo@sluggo-kubuntu:~$ sudo lshw -C network

Any suggestions on what to do?
thanks

You have a Broadcom Ethernet controller. Have you looked at System Settings > Driver Manager to see if there is a Broadcom driver you can enable?

My device manager list is empty. Nothing about broadcom in there.
