I use a wireless connection to connect to the internet. It works out of the box in Ubuntu. I installed Windows XP inside VirtualBox and even it was able to use the connection. I installed the guest additions also.
Now my host Ubuntu is not able to connect to the wireless network anymore. It is an open network. So no I have no internet for Ubuntu nor its guest Windows XP.
The network is fine as other laptops are able to connect to it. Right now I am typing this from another Ubuntu laptop connected to the same network.
Can anyone help me with reconnect my laptop to the network?
