Network on ubuntu guest fails after restart

[sam452]

I have successfully gotten a network connection with the help of the docs here in virtualbox's guest inside Windows 8.1 running on my macbook pro retina. My vb version is 4.3.18. I have earlier set up my /etc/network/interfaces as follows:

Code: Select all

auto lo
iface lo inet loopback
nameserver 8.8.8.8
nameserver 8.8.4.4

My guest network was set to Bridged and worked until today after I did a restart. Some Windows updates happened as well.

The only network option that works is NAT Netword. It gives a different class of addy which I'd rather not have but at least I can connect to the internet. How can I get my Bridged option to work and stay that way after a restart?

Under NAT and Bridged there is NO connection to even the Windows host addy. Only ping for localhost works as you expect.

Here is the output of my ifconfig:

I researching I saw some point to a different "wired" adapter, eth2. As you can see I have not changed the naming of these interfaces. What can I provide to help solve this issue? thx, sam
