I just performed a fresh install of Ubuntu 12.04.3 64-bit, and I cannot connect to the internet.

Ubuntu is installed on its own partition, with Windows 7 on the other. Yet while I'm able to connect to the internet using Windows 7, I am unable to do so using Ubuntu.

I use a Linksys Wireless-G USB network adapter dongle (WUSB54GC). It shows that I am successfully connecting to my router over wi-fi.

I had successful internet connection when I was using the 32-bit version of Ubuntu 12.04.3.

Can you help?

Thank you.

try these lines once -

sudo apt-get purge bcmwl-kernel-source
sudo modprobe -rv wl
sudo modprobe -v brcmsmac

answer taken from here.

If error comes ignore them and reboot your PC then see if its working.

hope it will work now.
