Comment 4 for bug 306469

network manager 0.7.996 in Ubuntu alpha 6 still will not release auto eth0 if it detects a wired connection.

My case: I use a USB wireless card to connect to the internet. If I run Ubuntu in VirtualBox, metwork manager detects the virtual wired connection to VirtualBox and refuses to allow me to deselect auto eth0. Network manager detects the wireless USB card but refuses to use it as long as it detects the virtual wired connection. I can connect to the wireless router in the host system (Ubuntu 8.04.3) and pass it along to the guest system on auto eth0. If I deselect auto eth0 in the guest system, it claims to disconnect then immediately reconnects, preventing me from using the USB wireless card.

I run Ubuntu Karmic alpha 6 in VirtualBox 3.0.6 on Ubuntu 8.04.3.
