Problem of Ethernet connection and VirtualBox

[Sean J]

Yesterday, I went with difficulty to VirtualBox 2.2.0 because I could not configure the network settings before launching the OS because the virtual network cards do not appear in the application master.

After some research I saw that I was not alone and that a repair could have the cards. Ok I do the repair then reboot. Miracle it works and I can access internet in my virtual sessions.

As against to my surprise, tonight I have no Ethernet connection on the main OS even when VirtualBox is muted. (no attribution ip). The connection is via an access bridge.

Do you have any idea why I can not have a connection to my OS?

Precisely 2 VBox uses over virtual network card installed on the host machine. You can configure the bridge directly in VBox more in the host OS. So, we must remove the virtual network adapter and the associated bridge, and rebuild the bridges directly into the network preferences of each virtual machine in VBox.

Indeed, the problem does not come from VirtualBox because I deleted VirtualBox and its the same.

My main OS can no longer take ip from dhcp; When I manually put the info it appears connected but no web while the gateway and dns were informed

The same if connecting to another network

I also tried but without result:
moving WinsockFix
to remove my card and reinstall

You have verified that there was no network bridge in your network configuration? Deletes everything bridge and VirtualBox NIC.

[Sean J]

At the main OS network config:
My connection to the LAN Ethernet with no connection
My wireless connection is disabled
My connection is disabled bluetooth

My virtual config
Network type: PCNet fast-III
Access Mode: access by bridge
map to access Realtek

Side event log there is a DHCP warning code 1007, but when I uninstall completely virtual I can not find my connection provided

For against, I have an unknown network device (root/net/002) I have activity from that

I deleted all the bridges but it was the same. So I reinstalled windows and now it's ok
