virtualbox.org

I have a Win 7 OS. Initially I had a VirtualBox v 4.2.6, everything was ok on my network adapters. I was able to see the Lan adapter and the Wifi adapter.
After upgrading to 4.3.6, I don't have any adapter there anymore. I have internet over them, but can see them in Control Panel\Network and Internet\Network Connections

It's nothing there but the VirtualBox adapter.

Does that mean a Win7-64bit host?

Try and uninstall/reinstall, making sure to run the installer using "Run as administrator", and also make sure that you are not configured to silently reject non-MS drivers.

It's a 32bit OS, I already did, uninstalled and reinstalled with admin rights. Nothing.

I tried to send you a screen shoot but I'm not allowed.

You can post screenshots as attachments (see "Upload attachment" tab in the new message form). Only URLs are not allowed.

btw. If you want to post screenshots, post one that shows the network devices branch of your host Device Manager.

Here it is.

Sorry, with the information given I can't tell you what's wrong.

Please state your problem again. Be clear on all the important points, particularly whether you are talking about things seen in the host or the guest. The thing that throws me is that you say that the internet connection still works, you just can't see the NICs, all you can see is the VirtualBox adapter. No matter how I try to model your problem, that statement doesn't make sense to me. E.g. if you were saying that NICs were missing from the list of those that can be bridged to - none of the VBox adapters would be listed there. If you're talking about the list of adapters visible to the guest... well it's a VM, it doesn't see host NICs. It'll see whatever you've told VBox to emulate... but the VBox name shouldn't appear there either.

Most of the "NICs" listed in your picture are not real: I would expect that only the top one can be bridged to.

I had installed VirtualBox 2.6 installed on my Asus V55 Laptop with Win 7 32bit OS installed, windows updates deactivated. With this version all my NIC (Atheros Lan and Atheros Wifi were displayed in control panel). I wanted to install on another VirtualBox VM Mac -OSx Lion. I got some error messages and after some google search on a forum post suggested to upgrade to a latest version. So I did. And after upgrading to latest version (standard instalation with all components installed), I've noticed that my NIC dissappeared from control panel, just like in that screen shot.

Please note that my NIC adapters are working properly.

Are you saying that just by installing VirtualBox it makes your host's physical NICs to disappear?

Exactly this happend after installing VirtualBox 4.3.6 over VirtualBox 4.2.6. No other software was installed.

And I've quit trying to install Mac OsX on it. Then I've removed the VBox with Uninstall, rebooted the pc, reinstalled the VBox without any network support and nothing happend.

"Awsome support". After your app crippled my computer I have to wait a year to find a fix to it. Nice app but terrible support.

Well, you realize that this forum is not an official support channel?
And none of the volunteers here work for Oracle?

If you want real support you need to buy a support contract from Oracle. This site is a user self help forum.
