Virtualbox, no network in Windows 7

[a_small_cake]

Hello,

I'm having problems with setting up network connection inside guest machine. Fedora 14 32 bit is host machine. Windows 7 Enterprise 32 bit is guest machine. I'm virtualizing system with Virtualbox "non-free" edition.

So, Guest Additions are already installed and Windows 7 recognizes network cards (there is no error related to driver etc.). Everything should have worked fine. But it doesn't. I can't manage to establish connection with internet on guest machine and I'm lost.

Have you got any tips for me? Thanks

Which type of network did you choose in the VirtualBox configuration? Options are NAT, Networkbridge, internal Network and Host only (names are probably different as I don't use english version).

The easiest way to the internet is using NAT. Usually the guest automatically connects and gets its IP from DHCP.

I'm using NAT. I have also tried other configurations but without success. I see icon with yellow triangle saying "no internet access". I remember that about year ago or so, when I had RC version of Windows 7 installed in Virtualbox, I could use internet connection. I have no idea why can't I connect to internet today.

Somebody had posted a message here but it got deleted (don't know why). Here is my lsmod | grep vbox output:

Module                  Size  Used by
vboxnetadp              5406  0 
vboxnetflt             12993  0 
vboxdrv               153590  2 vboxnetadp,vboxnetflt

I have just installed Ubuntu 10.10 on the very same Virtualbox. Network works "out-of-the-box". So, is it some issue with kernel, maybe? At least I'm sure that my Virtualbox installation and configuration is valid. But still I have no idea why network in Windows 7 would not work.

My bad. It doesn't work in any system

This is how it looks like:
