I don't know what to do. Every install of either 13.04 and 12.04 on my Dell does not have a working wired or wireless internet connection. However, if I am running from USB in the trial mode I have working internet through a wired connection using the same ethernet cord.

I honestly at this point do not know what I can do to fix this issue as I have gone through every possible fix I have found here and in other places.

Try clicking on the network icon then on Connect to hidden WiFi network, this may help. if not, can you tell us the make and model of your PC and the wireless card. –  SimplySimon Jun 26 '13 at 15:24
    
Laptop is a Dell Inspiron 1501 with a Broadcom Wireless card. Negative on the hidden WiFi network as well. –  Niven Jun 26 '13 at 15:49
    
Try sudo apt-get remove bcmwl-kernel-source then sudo apt-get install bcmwl-kernel-source as in the following information page help.ubuntu.com/community/WifiDocs/Driver/bcm43xx –  SimplySimon Jun 26 '13 at 16:05
    
For this I would need a connection to the internet. As it stands I have neither a wired or a wireless connection. –  Niven Jun 26 '13 at 23:39
    
This is a tricky one, just got up with a fresh head on, I'll try and find something that will help. –  SimplySimon Jun 27 '13 at 8:12

I had the same issue which I could not fix. I eventually fixed it using the method below.

In package manager remove bcmwl-kernal-source, then reboot. You should find the wired LAN connection then works.

To get the wireless working install linux-firmware-nonfree then reboot again. You will probably need to enable the adapter with Fn + F2 but should work after that.
