I'm using a bridged adapter, and sometimes switch between wireless and ethernet which means switching adapter type in the network settings. Also, VB won't connect when on my wireless at work (secured or guest). Sometimes I can get connected by using my phone as an ethernet hotspot via USB connection.


Is there a way to configure VB so that it is agnostic as to how Windows is connected to the internet?

Ubuntu 14.04 as VirtualBox guest under Windows 10.

Under NAT, Ubuntu connects, but no internet access.


abalter@U1:~$ ifconfig

I haven't tried this, but I have had the same problem you are facing and so I'm pondering a solution - have you tried bridging the two adapters in Windows? You may then be able to attach your vbox bridge to the windows bridge (or either adapter) and get a usable connection. Just a thought, which I know there are some potential issues with - so let me know if it works!

    Which two adapters do you mean? How would I bridge them? Not familiar with doing that.
