Hi guys,
I am very new to linux, I have a dual boot system running ubuntu 12.04 and windows 7 on a Dell Latitude E6320. I have no problem connecting to the internet on windows 7. Also I have no problem with the wireless connection at university. My only problem is connecting at home on ubuntu, I tried both wired and wireless at home and they are connecting but the internet is not working.
Here are some wireless information I gathered:
