Help !!! ...Can't access internet on virtual box ...:(

I haven't used VirtualBox ever, but I have been using VmWare for quite long time now. Vmware got some settings regarding to how it will gain internet access...like if it will duplicate the machine's IP etc. Try checking through the options of virtualbox and adjust settings that have to do with your network card and router. If nothing works, try to contact their support forums, I am sure there will be people available to help with your problem. Hope you resolve the problem soon, have a nice day!
