Hi, it looks like you have the wrong driver installed.

You do not have internet with a wired connection? If you do not then you can use this link to install the drivers for your 4312 wireless card.

Just make sure you do not install bcmwl-kerrnel-source.

Hi, open synaptic and type bcm in the search box then you will see broadcom drivers the ones that have a little green box are installed click on them on remove.

Do you have a wired connection?
