Unhappy Stuck on getting wireless conection, Ubuntu 14.04 LTS?


Hello!
I'm new to Ubuntu 14.04 LTS 32-bit and i'm running on dual boot with Windows 7 (the wireless in windows 7 works perfectly, wireless card- Dell Wireless 1397 WLAN mini-card), but I can't/not sure how connect with my wireless network. I have looked in network connections, but it doesn't seem to pick up any signs of my wireless (WPA2-PSK with AES encryption if that helps). So I havent been able to get any updates or additional software. I have looked on other forums and tried the "apt-get" commands on Terminal but it can't find the files I want. So far I have achieved very little. Please could I have directions as to what I should do next?
P.S. if there are any software downlad recommendations for ubuntu once the internet is up, I would gratefully take any advice.

Dell does not manufacture the wireless adapters--they resell OEM components. The most important bit of information to diagnosing this is the wireless chipset in the computer.

If you open a terminal and run the command lspci (list pci devices), the wireless chipset should be listed in the output of the command (assuming you are not using a USB wireless adapter). Post that information back to this thread, being sure to surround it with "code" tags for readability, which become available when you click the "Go Advanced" button to the right of the "Post Quick Reply" button at the bottom of the reply window.

BCM4312 is a proprietary driver. Ubuntu should have an "Additional Drivers" section that will download drivers for you. You may need an active internet connection.

Thanks for all the help so far,
I can't get any active connection on ubuntu (doesn't detect ethernet either), but I looked for additional drivers and apparently there are no additional drivers for me at the moment. Does this mean I'll have to use Windows 7 to import the drivers somehow, or do something else?

Or download the packages to usb & use gdebi to install.
If there are any missing dependencies you'll have to download them also.

Thank you all!
I have used a WORKING ethernet cable and I managed to automatically connect wirelessly too. I must say though, I'm slightly annoyed that the solution was this simple.
Anyway, thanks again and hopefully after I get to grips with Ubuntu, I can rid the system of Win 7.
