Worked for me too, but no idea why. What does Broadcom has to do with Realtek? –  tpv Oct 31 '13 at 10:25

I found the best solution to this is to remove the network manager and install wicd

Here is how to make the switch:

First, install WICD. Open a terminal and type:

sudo apt-get install wicd

Second, uninstall NetworkManager.

sudo apt-get --purge autoremove network-manager
