I have installed Kali Linux in Virtual Box as a VM. I use a wire network to which I login at a portal for internet access. But when I use the VM, I have to login to the portal inside the VM. I am new to Kali, but my setup used to work for backtrack 5. Also, a parallel windows XP VM can access internet just fine.

My settings in VM :

Network: Bridged Adapter

When I login in the VM, both my host system (Windows 8.1) and the xp XM that had internet access can't access anymore until they login to that portal.

Please help. I am not able to update install new packages. (Let alone follow the tutorials for learning tools in Kali Linux.)
