Anyone have LXDE running with Ubuntu 16.04 correctly?

So I just recently installed LXDE to get a desktop environment for my BBB on Ubuntu 16.04 distro. It works, (when I use 4D system’s 7’in LCD cape I can see the desktop gui) but now I noticed I cannot access the internet connection anymore whether I connect to the BBB serially, when I ssh, and when I use the gui. I noticed this happened right after I installed LXDE. I have tried all sort of workarounds like even trying to share my Mac’s internet connection but all attempts failed. Any ideas or comments?
