No internet connectivity in virtual-box with both Host and Virtual OS being 12.04

The NAT connection needed to be selected with the hardware being:

AMD PCNet FAST III (Am79C973, the default)

This works with almost any OS (as mentioned on the Virtualbox help page). The Intel setting for some reason did not work.

For Network setups with heavy router settings, you may have to use Bridged option with "PCNet FAST III" as the default.

VB likely made a "Unidentied Network" connection to your real machine and it uses this as its source for internet connection. Follow the settings below to check your basics for getting internet to work in you virutal OS.

Network Settings: *Select NAT under "Attached to:" *"Adapter Type:" MT Desktop (only can be changed when vm power is shut off) *"Cable connected" box is checked

System Settings: *"Network" box is checked in the "Boot Order:" listing.

Just wanted to let everybody know that I fixed the issue by uninstalling Virtualbox from the Software Centre, and by installing the copy I found on virtualbox.org website. Then I also set the adapter to AMD PCNet FAST III (Am79C973, the default)
