Ubuntu – How to make the Dell 1390 wlan minicard work

I have a dell laptop with at dell wireless 1390 wlan mini-card driver, when I installed Ubuntu side by side with Win7 I assume it was missing a wireless driver since that's what it said. Later on I reinstalled completely to ubuntu, and connected my laptop to a internet cable assuming it will get all the drivers from ubuntu servers/depositories.

So the problem now is that in the networking tab I dont even see a wireless connection option, when I go to System Settings -> Additional drivers, it shows me that im using Broadcom STA proprietary wireless driver. But I still don't see my Wireless connection.

I have looked for tutorials but they are mostly too old.

Can someone please provide me with a step by step guide or some guidance on how to fix this issue, or give me a link to a place where it's shown how to fix it.
