Hello,
I have faced a problem and I'm already stuck. Gonna describe it soon but first some info: I'm running Win8, my VBox is 4.3.12, I'm using wireless connection.
The problem I'm having is I can't use BridgedAdapter. It is possible that I'm making some foolish mistake because I'm a beginner in this topic.
I have two vbox system installed: win xp and linux. When I have NAT chosen in Network Settings, then my vbox internet connection works fine. (But here I'm getting some kind of internal IP and I want the vbox system to be treaten like it was a normal, separate machine/host, with it's own IP etc). I read somewhere that I have to use BridgedAdapter. The problem is when I switch to it - my Internet Connection just stops working. Can't connect to anything (both linux and windows). Is there any way to solve it?
Please excuse the beginner if he asked something silly. I'd appreciate some detailed tips if possible.
Have a good day, cheers!

This is usually due to an issue with your Wireless access point. Some have problems with Virtual Machines bridging to the unit. Most have special settings to help get around this issue, but that is something you would need to look into. I know that ones based or dd-wrt work fine with virtual bridged guests.

Well, as I mentioned, I'm a beginner. Could you provide me some detailed tips? Any how-to? Would be great!

Not really. I have an access point that is dd-wrt based so it just works. I would do some searching on the web and see what comes up. You should know what your access point is and that would also be a place to start. Most if not all have a support forum. That said it would probably be a security feature that is on by default if it is addressable.

If you do find out what needs to be done it would help if you posted it here so others can see.
